Q & A

What is the main focus of the video by Sean Wata?

The video focuses on deploying ERC 721 smart contracts, explaining the ERC 721 standard, and showcasing how to use the third web platform to create various types of ERC 721 NFT contracts.

What is the difference between ERC 721 and ERC 20 tokens as explained in the video?

ERC 721 tokens are non-fungible tokens (NFTs), meaning each token is unique and cannot be exchanged one-to-one, unlike ERC 20 tokens which are fungible and every token has the same value and attributes.

What are some use cases for ERC 721 tokens mentioned in the video?

Use cases for ERC 721 tokens include digital collectibles such as unique digital art, virtual pets, wearable items in games, and other digital assets that need to represent individual ownership and uniqueness.

How does the video introduce the third web platform for deploying smart contracts?

The video introduces the third web platform by showing the user interface, explaining how to connect a wallet, navigate to the contracts tab, and deploy pre-built ERC 721 smart contracts by filling out contract parameters.

What is the significance of the 'lazy mint' feature in the context of the NFT drop contract?

The 'lazy mint' feature allows for the prepping of NFTs by creating their metadata without minting the actual tokens. This means when someone claims an NFT, the metadata is already prepared, and the NFT can be minted and assigned to the claimant promptly.

How can royalties be set up for an ERC 721 smart contract as described in the video?

Royalties can be set up during the deployment of the smart contract by specifying the wallet address to receive the royalties and the percentage of royalties for secondary market sales.

What is the purpose of the 'claim condition' functionality in an NFT drop contract?

The 'claim condition' functionality allows the contract owner to set specific conditions under which NFTs can be claimed by users, such as setting a price for the claim, limiting the number of NFTs per wallet, and defining phases of availability.

How does the video demonstrate the creation of an NFT with the third web platform?

The video demonstrates the creation of an NFT by navigating to the NFTs tab, clicking on 'mint an NFT', providing a name, media file, description, properties, and attributes, and then confirming the transaction to mint the NFT to the user's wallet.

What is the difference between the NFT collection smart contract and the NFT drop contract?

The NFT collection smart contract allows the owner to mint unique NFTs with distinct metadata, while the NFT drop contract enables the public or specified users to claim NFTs that have been pre-minted with metadata prepared in advance.

How is the open edition ERC 721 smart contract different from the other contracts discussed in the video?

The open edition ERC 721 smart contract differs by allowing multiple tokens to share the same metadata. This is useful for scenarios where all NFTs in a collection look the same, such as event tickets, and only the token ID differs.

🚀 Introduction to ERC 721 Smart Contracts

Sean Wata introduces a tutorial video on deploying ERC 721 smart contracts. He outlines the video's content, which includes an explanation of the ERC 721 standard, its distinction from ERC 20, and a demonstration of deploying these contracts using thirdweb. The video promises to cover various types of ERC 721 contracts, their use cases, and the rationale for choosing one over another. The tutorial begins with a fundamental understanding of ERC 721 as non-fungible tokens (NFTs), often associated with digital collectibles, and their unique attributes compared to fungible tokens like ERC 20.

05:01

🎨 Use Cases and Deployment of ERC 721 Tokens

The speaker delves into the use cases of ERC 721 tokens, such as digital collectibles, virtual pets, and in-game items, emphasizing their unique value and rarity. He proceeds to a live demonstration on deploying ERC 721 smart contracts using thirdweb, detailing the process from connecting a wallet to deploying a contract. The video showcases the pre-built contracts available on thirdweb and guides viewers on how to fill in contract parameters, select a blockchain network, and deploy their contracts, recommending the use of testnets for initial testing.

10:02

📝 Navigating the Thirdweb Dashboard and Creating NFTs

After deploying an ERC 721 smart contract, Sean navigates the thirdweb dashboard, explaining its features such as analytics, code snippets, and the Explorer tab for interacting with the contract. He demonstrates how to mint NFTs by providing a name, media file, and other metadata, clarifying the difference between the NFT token and its associated media. The dashboard also allows for setting up royalties, primary sales, and managing permissions for NFT minting, giving the contract owner control over who can create new tokens.

15:02

🔑 Permissions and Advanced Features of ERC 721 Contracts

The tutorial continues with managing permissions for NFT creation, allowing for the addition or removal of wallet addresses that have minting privileges. Sean also introduces the concept of 'lazy minting,' which prepares NFTs for future claiming without immediately creating them. He discusses the 'claim conditions' feature in NFT drop contracts, which sets the parameters for when and how NFTs can be claimed by users, including setting claim phases, prices, and limits per wallet.

20:04

🌐 Embedding NFT Drops and Customizing Claim Conditions

Sean demonstrates how to set up claim conditions for an NFT drop, allowing the public or specific wallet addresses to claim NFTs under certain parameters. He introduces the 'embed' feature, which allows creators to embed the NFT drop interface on their websites for a seamless user experience. The video shows how to customize the embed with themes and colors, and how to use it to claim NFTs directly from the website, enhancing the accessibility and user-friendliness of the NFT claiming process.

25:04

🎟️ Open Edition ERC 721 Contracts for Shared Metadata

The final part of the video covers the open edition ERC 721 smart contract, which is used for minting NFTs that all share the same metadata, such as event tickets or collectible items that are identical in nature. Sean walks through the deployment process, setting the metadata once for all tokens, and configuring claim conditions similar to the NFT drop contract. He illustrates the process of minting multiple NFTs that reference the same metadata, simplifying the creation of large collections with uniform attributes.

👋 Conclusion and Final Thoughts

Sean concludes the video by summarizing the key points covered, including the ERC 721 standard, the different types of smart contracts deployed through thirdweb, and the practical steps for deploying and managing these contracts. He encourages viewers to like, subscribe, and turn on notifications for more content, and offers assistance through a support ticket link in the video description for any questions or help needed in deploying their own ERC 721 smart contracts.

Keywords

💡ERC 721

ERC 721 is a standard for creating non-fungible tokens (NFTs) on the Ethereum blockchain. In the video, it is the main focus as the presenter discusses deploying ERC 721 smart contracts. The standard allows for unique digital assets, each with distinct attributes and ownership, which differentiates them from ERC 20 tokens that are interchangeable and identical.

💡NFT

NFT stands for non-fungible token, which is a digital asset that represents ownership of a unique item or piece of content, such as digital art or collectibles. In the script, NFTs are explained as being different from ERC 20 tokens due to their unique attributes, and the video provides an overview of how to deploy NFTs using the ERC 721 standard.

💡Thirdweb

Thirdweb is a platform mentioned in the video that simplifies the process of deploying smart contracts, including ERC 721 NFTs. It offers a user-friendly dashboard and pre-built contracts that can be easily customized and deployed by filling out a few parameters, which is demonstrated in the script.

💡Smart Contracts

Smart contracts are self-executing contracts with the terms of the agreement directly written into code. In the context of the video, ERC 721 smart contracts are a type of smart contract that facilitates the creation and management of NFTs, with specific functionalities like minting and claiming NFTs.

💡Minting

Minting in the context of NFTs refers to the process of creating a new token and adding it to a blockchain. The video script explains how to mint NFTs using ERC 721 smart contracts, which is a key step in bringing a unique digital asset into existence.

💡Metadata

Metadata is data that provides information about other data. For NFTs, metadata includes details like the name, description, and attributes of the digital asset. The video emphasizes the importance of metadata in defining the unique characteristics of each NFT and how it is linked to the ERC 721 token.

💡Claim Conditions

Claim conditions are the rules or requirements set for users to claim NFTs from a smart contract. The script discusses how these conditions can be configured, such as allowing only certain addresses to claim NFTs or setting price and limit for public claims.

💡NFT Collection

An NFT collection is a group of NFTs that are often thematically related or part of a specific series. The video script describes deploying an 'NFT Collection' smart contract, which allows the creator to mint multiple unique NFTs for a collection.

💡NFT Drop

NFT drop refers to the release of NFTs for sale, often with a focus on limited availability or special access. The script introduces an 'NFT Drop' contract, which includes functionality for users to claim NFTs under certain conditions, like paying a price or being on an allow list.

💡Open Edition ERC 721

An Open Edition ERC 721 contract allows for the minting of multiple NFTs that all share the same metadata. This is useful for scenarios where identical NFTs are desired, such as event tickets or limited edition digital goods. The video demonstrates how to deploy such a contract and set its metadata.

Transcripts

hey everyone Sean Wata here back with

another video and in today's video what

we're going to be doing is deploying our

very own ERC 721 smart contracts this

video is going to cover a lot of things

and an overview of what we're going to

be covering we'll first go over what is

the erc721 standard how is it different

from your other standards like erc20 and

ERC

1155 then we'll jump into third web and

we'll show you how to deploy your very

own ERC 721 smart contracts we'll go

through some of the different erc721

smart contract that you can deploy

easily using third web and what some of

the different use cases for those smart

contracts can be and why you would

choose one over another and that is

again a quick overview of what we're

going to be going over in this video but

to start off let's first cover what is

the ERC 721 standard and how is it

different from your other standards like

erc20 so an ERC 721 is a non fungible

token or an nft now you may have heard

of an nft before you might be familiar

with it they are normally referenced and

referred to when people talk about

digital Collectibles you might know it

as like those Avatar or profile pictures

of different animals or different you

know styles of Art and that is what an

erc721 token is they are nonf fungible

tokens that is what nfts stand for but

what does non-fungible mean let's you

know break that down a bit first so

non-fungible means that each token is

unique it can't be exchanged one to one

because one token uh differs in value to

another token unlike an erc20 where all

the tokens that you create are all the

same they have the same values same

attributes uh erc721 each of the tokens

created are unique in their own way you

can think of this as like maybe you have

a piece of art if you have a painting

it's not the same as other paintings

each piece is unique it has its own

value therefore it is non one ible now

let's cover some maybe use cases of ERC

721 tokens or nfts a popular use case

and you might hear people mention this a

lot when they talk about nfts but

digital Collectibles imagine you have a

platform where you can sell buy and

trade these unique digital assets uh you

can think of these like maybe um digital

art virtual pets wear items in games uh

all these different things can be

represented by an ERC 721 token and this

ensures that every item is distinct and

can be owned and traded individually the

non-f fungibility of these tokens make

each digital asset unique and valuable

there can be Rarity to these as well and

depending on the attributes that you

provide these digital assets that can

change the value of what they are worth

to one another so now that we have a

little better understanding of what an

erc721 token is let's jump on the

computer here and let's deploy and go

over some of the different ERC 72 when

smart contracts third web has to offer

all right so on my computer here I am on

third web.com I've connected my wallet

and I am now on the third web dashboard

from here we have our different tabs

here and we're going to head on over to

the contracts Tab and here on the

contracts tab you can see a list of all

the contracts you've deployed using

third web and up in the top right you'll

see a blue deploy contract button so

click on that and this is the list or

our Explorer page of all the different

pre-built contracts that you can deploy

through third web now we have these

pre-built contracts they're easy to

deploy all you need to do is fill out a

few pieces of information for the

contract parameters and you can click a

button and deploy the smart contract now

again we're going be covering ERC 721

smart contracts there are a few of them

here and most of them are going to be

under this NFS tab if you remember

earlier uh erc721 is a non-fungible

token or nft and we're going to just hit

view all in this nft section here to

look at the nft contracts that we can

deploy now you're going to see some ERC

721 smart contracts along with ERC 1155

smart contracts and we'll cover ERC 1155

in a different video uh but this one

we're just going to be covering the ERC

721 smart contracts now we do have a few

of them the three that we're going to be

going over is these top three right over

here we're going to go over the nft

collection which is your standard ERC

721 smart contract we're going to be

going over the nft drop contract this is

going to be a contract that maybe you're

more familiar with but it's an ERC 721

smart contract with the ability for

other people to claim ERC 721 nfts from

the contract so this is like your

traditional nft drop maybe if you're

familiar with like those pfps or avatars

uh and you want to charge someone for

claiming an nft you'll use the nft drop

and we'll go over what the drop

functionality and claim condition

functionality is in a bit and then we

have the open Edition ERC 721 so we'll

go through all of these different ones

in depth as we start to deploy them but

we'll start off here with the nft

collection so if I click on this you can

see this is an ERC 721 smart contract

you can see some of the use cases and

examples of why you might want to use

this smart contract you can create a of

many collection for maybe like your

photography or your artwork uh you can

create a one ofone nft collection uh

maybe you want to Min your artwork as

nft sell them on a Marketplace um these

are going to be for you to create these

again unique nfts and the difference is

only you as the deployer and owner of

this smart contract are going to be able

to create these nfts for the smart

contract if you look at the nft drop

which will deploy next you'll be able to

allow other people to claim and mint

these nfts uh but the nft collection

here this is only strictly for if you

the owner wants to be able to have the

sole permission to uh mint and create

these nfts so what we'll do is hit the

deploy now on the top right you'll see

you can fill out your contract

parameters here from the name uh we'll

just call this our nft

collection uh symbol we just call this

nft you can add a contract image a

description now you can also set the

royalties and price Ary sales so

royalties this is for if you sell your

NFC on a secondary Market this is the

wallet address that the royalties are

going to go to and you can set to the

percentage of royalties here so if the

marketplace that you're selling supports

royalties this is what it's going to be

taking and that's where it's going to be

sending the royalties to you have

primary sales so this is going to be the

initial sales of nfts this is the wallet

address that it gets sent to now down

here at the bottom you'll see network in

Chains where you can select the drop

down and you can select any evm

compatible blockchain uh you can select

main Nets test Nets you can just put

search the network name or put the chain

ID in here and you can again deploy the

smart contract to any evm compatible

blockchain out there so we make it super

easy uh for you to deploy a very own nft

or ERC 721 smart contracts now I have

some sepolia eth here so I'm just going

to click on sepolia and I highly suggest

that you deploy your smart contracts to

a test net first try it out get some

test net funds and you knowest test out

deploying these smart contracts before

you go to mainnet but once you have

everything filled out here go ahead and

hit deploy now you'll get a popup here

this is going to uh give you the

transaction here to deploy your smart

contract so you're just going to have to

pay for the gas I'm going to hit confirm

then we'll get another popup here this

is going to be a signature request for

adding your contract to your third web

dashboard now our dashboard gives you a

really userfriendly UI to manage and uh

EX Ute and interact with your smart

contracts so he just going to sign that

right over

there and once that is successfully

deployed you'll be brought to your

contract dashboard you'll see here the

name of your contract uh the chain that

you deployed it to uh your contract

address here you can copy that um you

have a contract checklist so you can see

we already deployed our contract the

next thing to do is to Mint our own nfts

uh which we'll go over in just a bit uh

but we'll first go over some of the

other navigation here on the left so

this is your overview page this gives

you a very general overview of your

smart contract from the analytics the

latest events and everything uh you can

look at code Snippets so if you're

looking to build or interact with the

smart contract through our SDK uh we

have typescript um react you can use

this in unity uh react native you'll

have all the code Snippets and

everything here to kind of get you

started so you can see if we want to

transfer an nft this is the code snippet

here you can copy that you can start

building out your frontend applications

for interacting with your smart contract

uh below that we have the Explorer tab

this is where you can actually interact

with your smart contract you can view

all the write and read functions uh you

can execute these write functions here

you can think of it as a like how you

interact with your smart contract do

something like a block Explorer you can

again you can mint you can do and

execute any of those functions from the

smart contract directly right here in

your dashboard below that you have uh

events so all the events that get

emitted to the blockchain through the

smart contract will be viewable here you

have analytics as well so you can view

things like unique wallets total

transactions um and you can view the

analytics of your smart contract uh we

have payments here so this is if you

want to enable credit card checkout you

can enable that here we have your

settings so if you want to add or change

the contract metadata you can change

that here uh when you update it just

know that you have to pay for gas again

so if you want to set it up again

beforehand like when we deployed the

smart contract you can do it there if

not you'll just have to configure it

right here in your settings we have your

sources tab this is going to give you

all of the solidity code here that is

used to create this smart contract so

you can you know open it up and view all

of the solity code here if you want then

if we drop down here into the bottom we

have our nfts Tab and this is where we

can start creating our nfts for our

collection so right over here I can mint

an nft uh I can now create the nft that

I want by providing it a name the media

this is can be an image uh mp3 mp4 you

can I think there's a yeah list of

different uh media types that you can

put in here a 3D model PDF HTML whatever

you want the nft to be so how an nft or

an ERC 721 works is attached to the

Token is a reference to a piece of

metadata and that metadata is going tocl

include things um like the name uh the

reference to the image or the media file

is going to have a description you can

add attributes to it and that is what

connects the attributes and the

description of the nft to the Token it's

this piece of metadata here so a lot of

people think that the ERC 721 or an nft

is like a pitcher uh and that's the

common misconception that majority of

the world I think or majority of people

who kind of got their first taste of

nfts as you know these pictures of

monkeys that were selling for hundreds

of thousands of dollars um that isn't

technically um the nft itself the nft is

the token that is minted and created on

the blockchain the image and the media

is just what that token is referencing

to and that's just the visual aspect

that people can see um when they are

interacting And when they see an nft so

again you can create your own nfts here

you can just add a name so just say we

can and upload a file so let me just uh

just take like our little blob friend

here you can add a description uh you

can add properties and traits and then

you can mint the nft and what this is

going to do it's going to create this

nft it's going to create that erc721

token it's going to create the metadata

and Link that token to this piece of

metadata here we'll confirm that to

minted and this nft will then be minted

to my own personal wallet from here I

can you know list the nft for sale on

the marketplace maybe open C rar uh and

then I can put a price onto it and

people can then you know purchase this

nft on those marketplaces or if you want

you we actually have Marketplace

contracts and you can deploy your own

and build your own Marketplace to sell

your own nfts so there you go you can

see now we have our nft we have the

token ID uh which starts at an index of

zero and goes up from there you have

your media which is our image of our

blob friend here the name that I gave it

uh and then the owner so the owner is my

wallet address that deployed smart

contract because I'm the creator of the

nft and again from there we now have an

nft that we can list um on different

marketplaces and we can use it however

we want to down here at the bottom uh

below the nfts tab there's the

permissions tab this is where we can

give permission to other wallets to be

able to create nfts so maybe I have a

team of artists or a team of people who

want to create nfts for this smart

contract right now by default it's the

wallet address that deploys a smart

contract but I can add other wallet

addresses to here if I want to so um I

can also remove all the wallet addresses

completely and now no one has the

ability to add or create new nfts on the

contract so maybe I want to create a

collection of 100 unique tokens and once

those 100 unique tokens are created I

want to remove permission so no one else

can ever add tokens or Mint new nfts to

the contract I can remove everyone off

of it update the permissions and then

pay for the gas to execute that so in

permissions you can control the mentor

and Creator and that does it for your

erc721 nft collections let's come back

to contracts here and let's deploy

ourselves another contract so we're

going to hit come back to the contracts

tab we're going to hit deploy contract

go back to the nft section here and the

next one we're going to go over is the

nft drop so I'm going to select this one

here and the nft drop you can see the

use cases this is going to be for your

pfp collections maybe what you're

normally used to when you see nfts out

there U maybe you want to release art

work um and you know allow people to

claim and pay a certain price uh to

claim those nfts so what we're going to

do is just we're going to hit deploy now

we're going to fill out the contract

parameters similar like how we did with

the nft collection contract I'm just

going to call this one nft uh drop and

then we can give it a symbol here we'll

just say nft drop here and you can add

an image description you can fill out

the royalties and primary sales again

just like how we went over in the nft

collection you can come down here Selec

the network or chain you want to deploy

to select the drop down select that

chain and then deploy now confirm that

transaction you get another popup here

for a signature request again to add it

to your dashboard so you can sign

that and once your contract has been

successfully deployed you'll be brought

to your contract dashboard similar to

like the nft collection you'll have your

contract checklist here this one's a bit

longer and the reason for that is

because we have to set a claim condition

and that is again that functionality

that you get in an NF T drop or any type

of contract that has the drop extension

um it just has a claimable extension

that allows users to claim the nfts so

we'll come here to the left hand

navigation we'll come to the nfts tab

first and what we'll have to do is lazy

mint nfts to the contract so lazy mint

is not minting to create the token but

we're pre you think of lazy mint as like

a pre-int we're prepping the nft to be

created so that when someone claims an

nft we have the meta data and we know

what nft that person is going to be

receiving so you can single upload and

single upload is just like how we did

with our nft collection you can create

all of the nfts and metadata all within

this and you can provide it a name the

media file description properties

attributes um but if you're doing

something like a pfp collection or a

larger collection normally you'll

generate those pieces of metadata so

what you can do as well is do a batch

upload you have example CSV and Json

files here so you can download those and

you can upload all 100 all 500 all

10,000 of the pieces of metadata that

you want in your nft collection you can

just drop those files in here and then

you'll be able to Lazy Min them to your

contract on the left hand side here

you'll see a few different things um so

what I'm going to do actually is let's

just uh lazy Mint one nft here let me

just add in our blob friend here and

lazy mint this to our contract so we can

you know see an example of everything

we're going to go through here so let me

just confirm this transaction right here

all right so very similar to how we

created our nft uh collection contract

or the non-rop version of our ERC 721

contract and once we lazym this nft here

so you'll see that that was a lazy mint

not a mint like the nft collection

contract so we have our token ID we have

our media type the name similar to like

how we had before but the owner the

owner is no one the owner is null right

now this nft hasn't been fully created

and sent to a wallet address in our

previous ERC 721 contract when we

created and minted the nft it was

automatically put into our wallet and

created for us this one again is a lazy

Mint or kind of like a Prem mint where

we're prepping the metadata of the nft

for when someone does actually claim it

so I have one nft in here uh we'll come

down here to the claim conditions and

the claim conditions this is the

features uh that you get with with the

drop functionality now there are

different conditions that you can set up

and we'll quickly go through them so

only owner and you can hover over the

information icon here for a little

snippet about what it is only owner

means that only the owner or deployer of

the contract has the ability to claim

the nft example of this is you have a

maybe a collection of a 10,000 pfp

project that you want to uh launch and

you want to claim a certain set amount

for maybe distribution or for your team

members uh you can set the first claim

phase to only owner you can deploy the

contract get everything set only you as

the owner will be able to claim maybe

the first 25 nfts or 100 nfts and then

you can set it to the following claim

phases um and those claim phases the

next one will be like an allow list so

this is where you can have a list of

wallet addresses and only those wallet

addresses will be able to claim so if

you want to again create a list uh

through whatever means um to collect

those wallet addresses you can provide

it with the wallet addresses and only

those wallet addresses will be able to

claim uh we're going to skip up to the

public one and then we'll come back to

this public with allow lless but the

public this is going to apply to all

wallets so public means it's open to the

public uh you can set prices you can set

uh claim limits uh but anyone will be

able to claim within this phase then

there's a public with allow list this is

still a public claim phase but you can

override certain things with an allow

lless so let's just say in the public uh

with allow list the public price is 10

maic right let's just use that as an

example U but maybe if there is a list

of wallets in their allow list that can

purchase the nfts for fmatic so the

allow list will overrate the public

parameters that we input for the public

with allow list so those are the four

different claim conditions uh once you

select one I'll just select a public one

for an example you put in the name of

the phase when it's going to start uh so

you can set up multiple claim phases and

then it'll just roll into the next one

depending on the start time and date you

can put how many nfts will be in this

phase so maybe with the allow list one

it's an allow list but it's for the

first 100 people you can just say 100

nfts here you can put in a price and you

can also put in how many nfts per wallet

can be claimed so once you set

everything up you just hit save phase

you get a transaction that appears you

just have to confirm and pay for the gas

there you go and now we have a claim

condition set so again this is what the

drop functionality allows you to do um

again you set up all your nfts here you

can upload all your nfts set the claim

conditions now there is one extra tab

here uh that you see that we didn't have

on the previous nft collection smart

contract and that's the embed button and

the embed button allows you to get uh

create create your own embed which it'll

give you a preview down here and you can

then plug this embed into your own

website um wherever you want to put it

you can customize it right over here so

you can add gasless if you want to do

open Zeppelin relayer or bonom relayer

you can select your theme so we can say

dark you can see the preview down here

or we can set the primary color let's

just say blue to match our little blue

blob FR and you can just copy this

iframe right over here plug it into

wherever you want again this is going to

give you uh a full embed so you can see

here we have only one nft uh zero has

been minted uh but we have to connect

our wallet so we can like connect a

metamask wallet here once we're

connected you can see we can Mint one

nft uh it's free cuz we didn't put a

price in here so let's just claim this

and you get a transaction here you can

see we're going to claim token ID zero

uh we'll confirm that pay the gas and

once we claim the nft you'll see one out

of one here so again you can take this

embed plug it into wherever you want to

and you can you know launch your nft

collection as easy as that there you go

you can see we successfully minted and

now it is sold out because again we only

had one nft uh but there you go we can

close that and there you have it again

you can copy and paste this embed

wherever you want to and that does it

and covers the nft drop now we're going

to go over one last ERC 721 contract I'm

going to open up the contracts tab again

and we're going to go to deploy contract

and the final one that we're going to go

over is this open Edition ERC 721 so

what is an open Edition erc721 an open

addition ERC 721 is similar to like the

nft drop smart contract but instead of

you know creating different nfts for

each of the tokens all the tokens are

going to share the same metadata so you

set One Singular metadata and every

token minted is going to share that

metadata data so this is great for

things like maybe like a concert ticket

or maybe you want to launch uh something

that uh nft and all the nfts are going

to look the same and have the same

attributes um and but maybe you don't

want an ER something like an ERC 1155 uh

you still want an ERC 721 but you want

to share that metadata instead of you

having to you know duplicate the same

metadata over and over and batch upload

it you can just set that metadata once

um and then and all the tokens minted

will always share that same metadata

we'll go over an example of this we'll

deploy this smart contract um we'll just

call this our open nft and we'll just

say open again setting up your contract

parameters selecting your chain and

everything uh I'm going to hit deploy

now now you're going to see there's one

extra step here and that's called

setting your nft metadata so we're going

to have to confirm through two

transactions here so there you go um

another transaction this is for setting

the metadata we're going to hit confirm

and then we'll get that last popup which

is a signature request to add the

contract to our dashboard here we go so

signature request we'll sign that it has

been successfully deployed we brought to

our open addition ERC 721 smart contract

and you can see here nft metadata is set

it's preset um with a blank metadata so

we still have to set that up and then we

need to set up our claim condition so

we're going to come over to the nfts tab

and you'll see a button here that we

haven't seen previously in the other

smart contracts and that's the set nft

metadata so if we set the metadata here

this metadata that we set up here again

is going to be for all tokens claimed so

we can just make our little blob friend

again here you can add all your

descriptions whatever you want to set

the metadata as you can create that here

you only need to set it once so we set

the metadata here and then we're going

to

confirm and then once we have that set

again every nft that gets minted to the

smart contract is going to share that

metadata so over here we have a claim

condition we can set the same type of

claim conditions like we went over with

the nft drop contract so you have the

same for here I'm just going to set up a

public one and not charge any uh we're

going to save that and this is just

again so we can test out this claiming

and I can show you what I mean by every

nft is going to share the same metadata

so once that is saved we can come down

to the embed section here just to test

out our nft claims U but right here

you're going to see this come up and

what we're going to see here is our open

Edition nft oh I don't think we set an

image so it's not going to show anything

here uh but we can mint an nft here so

let me just Mint one and then we'll mint

a few more after that you can see here

we're going to Mint an nft here once we

mint the nft we'll take a look at it in

the nfts tab there you go nft has been

transferred to our wallet so if we go to

the nfts tab here we should see our nft

here so it says nft one it has our

little blob friend here and it has the

owner which is my wallet now

again we only set that nft up when we

set the nft metadata now let's come to

the embed here one more time and let's

claim oh let's set this load let's claim

three more so I'm going to Mint these

three and again what should happen here

is you can see all the three nfts that

I'm going to be minting all these nfts

that get minted again will share the

same exact metadata that the first nft

that we minted had so every single nft

in this collection is going to have the

same attributes it's going to have the

same

metadata but they are going to be erc721

tokens instead of me having to you know

create 10,000 of the same metadatas and

you know upload 10,000 of those metad

datas I can just set one metadata and

every token references the same piece of

metadata so once this finishes claiming

here there we go let's head back to our

nfts tab here and we should see three

more nfts here again all of the nfts are

the same they have the same metadata

same image uh we didn't put a

description or anything here uh and then

you have the owner which is all owned by

me but everything will share the same

piece of metad dat that way you don't

need to recreate the same piece if that

was the goal of you know your collection

so there you have it we went over a few

different things in this video we

covered what an erc721 standard is uh

which is essentially an nft or a

non-fungible token we also went over

some of the different smart contracts or

erc721 smart contracts that you can

deploy through third web and we actually

deployed these smart contracts

themselves this included the nft

collection smart contract which is your

ERC 721 contract your nft drop contract

which is your claimable RC 721 smart

contract again with that claim condition

functionality and then we had the open

Edition ERC 721 smart contract which all

nfts will essentially share the same

metadata making it easy if that is you

know the type of collection you're

looking to create but I hope you folks
