What Is Blast?

Blast is the L2 that helps you earn

Blast is the only Ethereum L2 with native yield for ETH and stablecoins. Blast yield comes from ETH staking and RWA protocols. The yield from these decentralised protocols is passed back to Blast users automatically. The default interest rate on other L2s is 0%. On Blast, it’s 3.4% for ETH and 7% for stablecoins.

How Blast works

​Auto Rebasing

ETH itself, not WETH, STETH, or any other ERC20, is natively rebasing on the L2. The ETH balance for EOAs is automatically rebasing. Smart contracts can opt-in to this rebasing, making it easy for existing Dapps to deploy on Blast without any changes.

USDB, Blast’s native stablecoin, is automatically rebasing as well. Like ETH on Blast, USDB is automatically rebasing for EOAs. USDB is also automatically rebasing for smart contracts. Smart contracts can opt out of this rebasing.

​L1 Staking

Blast only became possible following Ethereum’s Shanghai upgrade. ETH yield from L1 staking, initially Lido, is automatically transferred to users via rebasing ETH on the L2.

In the future, the Blast community will have the power to supplement, or even fully replace, Lido Blast-native solutions or other third-party protocols.

​T-Bill Yield

Users who bridge stablecoins receive USDB, Blast’s auto-rebasing stablecoin. The yield for USDB comes from MakerDAO’s on-chain T-Bill protocol. USDB can be redeemed for USDC when bridging back to Ethereum.

In the future, the Blast community will have the power to supplement, or even fully replace, MakerDAO with Blast-native solutions or other third-party protocols.
