Keywords

💡Cross-chain bridge

A cross-chain bridge refers to a technology or platform that enables the transfer of digital assets between different blockchain networks. In the context of the video, the presenter is discussing the use of cross-chain bridges to optimize the process of obtaining airdrops from various blockchain projects. The bridges mentioned are used to transfer tokens from one blockchain to another at the lowest cost, which is crucial for maximizing the potential benefits from airdrops.

💡Airdrop

An airdrop typically refers to the distribution of a cryptocurrency token or coin, usually for free, by a project or team to a wide audience, often as a marketing strategy or to increase network adoption.
