Blast in one minute
Blast is an optimistic rollup on top of Ethereum. It runs the same smart contracts, wallets and tooling you already use, so moving a dapp or a wallet to Blast feels exactly like any other EVM chain.
The difference is the baseline. The default interest rate on other L2s is 0%. On Blast, bridged ETH earns yield from Ethereum staking (around 4%) and bridged stablecoins earn yield from on-chain T-Bill protocols (around 5%). It happens automatically, right in your wallet balance.
Why a new L2
After the merge, Ethereum pays yield on staked ETH, and on-chain T-Bill protocols pay yield on stablecoins. If your funds earn less than that, you are losing value to a form of inflation.
Existing L2s were not built with this in mind. Incorporating ETH and stablecoin yield natively requires a chain designed from the ground up, which is what Blast is. It raises the baseline yield for users and developers without changing the experience crypto natives expect.
Where the yield comes from
ETH · L1 staking
ETH bridged to Blast is staked on Ethereum, initially through Lido. Staking rewards flow back to users through rebasing ETH on the L2.
Stablecoins · T-Bills
Bridged stablecoins become USDB. Its yield comes from MakerDAO’s on-chain T-Bill protocol.
Over time the Blast community can supplement or replace these providers with Blast-native solutions or other third-party protocols.
Auto rebasing
On Blast, ETH itself is rebasing: not WETH, not stETH, the native gas token. Regular wallet balances grow on their own. Smart contracts can opt in, which lets existing dapps deploy without code changes.
USDB rebases automatically for both wallets and smart contracts. Contracts that need a fixed balance can opt out.

Risks to know
- Yield rates are variable and depend on Ethereum staking and T-Bill returns. They are not guaranteed.
- Like every L2 and bridge, Blast carries smart contract and operational risk.
- Withdrawals through the native bridge take several days because of the optimistic rollup challenge window.
- Scammers copy popular crypto brands. Only bridge through the official Blast app.
