Blast is an Ethereum layer 2 scaling solution, designed to provide users with native yield opportunities for both Ether (ETH) and stablecoins. It operates on the principle of optimistic rollups, a technology aimed at enhancing the throughput of the Ethereum network while maintaining security and reducing transaction fees. Blast has become notable for offering a unique feature where the yield from Ethereum's Layer 1 staking, primarily through interfaces like Lido, is automatically transferred to users on the Layer 2. This process is facilitated through rebasing ETH on Blast, allowing users to earn yields directly on the platform​​.

Blast is primarily used for enhancing transaction speeds and reducing costs on the Ethereum network, thanks to its layer 2 framework. Users can bridge their ETH and stablecoins to Blast to earn native yields. Specifically, when users bridge stablecoins, they receive USDB, an auto-rebasing stablecoin backed by Blast, with yields derived from MakerDAO's on-chain T-Bill protocol. This mechanism creates an attractive environment for both yield seekers and developers, providing substantial incentives and sharing gas revenues with developers on the chain. Additionally, there is an airdrop mechanism intended to reward early users and contributors to the network, further incentivizing participation and investment in the Blast ecosystem​​.

Blast was developed by a team led by Tieshun "Pacman" Roquerre, who is also known for creating Blur, a leading NFT marketplace on Ethereum. The project has received backing from notable investors in the cryptocurrency space, including Paradigm, Standard Crypto, eGirl Capital, Primitive Ventures, and others, collectively raising $20 million. This support underscores the industry's interest and belief in Blast's potential to contribute significantly to the Ethereum ecosystem​​​​.
