Blast: the Layer 2 that took off on "deposits that earn yield automatically"

In one sentence

Blast is an Ethereum Layer 2 built from a modified version of Optimism’s OP Stack. Its main selling point is native yield: deposit ETH or stablecoins into Blast and your balance grows by itself.

How it took off is typical: before mainnet even existed, it opened “deposit to earn points” with the promise of a future airdrop, and drew in billions of dollars within months. That makes it a good case study for the “points plus airdrop” playbook.

Where it came from

November 2023: Blast opened deposits. Users put ETH and stablecoins into a contract on Ethereum in exchange for points, but could not withdraw until mainnet launched. The deposit contract was controlled by a multisig at the time, and many researchers criticised it as “not a Layer 2 but a multisig wallet”.
29 February 2024: mainnet launched and withdrawals opened.
June 2024: the BLAST token was issued and airdropped. Locked value then fell sharply as the points campaign ended.

Where the yield comes from

Blast puts users’ deposits to work and passes the returns back to users:

how it worksHow money deposited in Blast earns yield

01Deposit
You bridge ETH or stablecoins from Ethereum to Blast.
02Bridged ETH is staked
Blast stakes the ETH in its bridge on Ethereum (for example through Lido) to earn staking rewards.
03Stablecoins earn Treasury yield
Stablecoins are swapped into products that earn US Treasury interest.
04Yield flows back
Returns are added pro rata to users' balances on Blast (ETH grows automatically; stablecoins become yield-bearing USDB).
05So does the risk
Behind the yield sit three stacked layers of risk: the staking protocol, the Treasury products and Blast's bridge contract.

“Automatic yield” does not come from nowhere: your money is being used for something else, and both the return and the risk come from there.

How L2BEAT sees it

L2BEAT does not classify Blast as a rollup but as “Other”. The key item is state validation: none. In other words, the “ledger result” Blast submits to Ethereum is not checked by any fraud proof or validity proof; whether it is correct comes down to trusting the operator.

Security stage: Stage 0 (L2BEAT does not count it as a rollup)

Stage 0
Still on "training wheels": proofs may not be live, or the operator can change the rules alone
Stage 1
Proofs are live, but a security council can still override or upgrade in an emergency
Stage 2
Fully governed by code and proofs; nobody can change outcomes unilaterally

If the sequencer failsIf the official sequencer goes down or censors you, can you still force your transaction in?

Self sequence

Good

State validationWho guarantees that the state the Layer 2 posts to Ethereum is correct

No proof system: correctness cannot be checked

Poor

Data availabilityIs all transaction data published on Ethereum, so the chain can be rebuilt if something goes wrong

Onchain

Good

Exit windowDo users have time to withdraw before the contracts are upgraded

None (can be upgraded instantly)

Poor

If the proposer failsIf the role that posts state to Ethereum stops, can users still withdraw

Cannot withdraw

Strengths and trade-offs

Strengths

Native yield: idle balances earn staking and Treasury interest.
Ethereum-compatible, so wallets and contracts work directly.

Trade-offs

No working proof system; correctness rests on trusting the operator, and L2BEAT does not count it as a rollup.
Yield comes from staking protocols and Treasury products, stacking extra layers of risk.
The money was mostly attracted by points and the airdrop, and much of it left once the campaign ended; the ecosystem is quiet.

Investigating a project on Blast? Check these first

01
For any "deposit now, earn points, wait for the airdrop" project: which contract controls the deposits, how many signatures can move them, and when can you withdraw?
02
Where does the yield come from, and who pays it? If the source of yield is unclear, so is the risk.
03
Pools are shallow and small-token prices are easy to manipulate; check liquidity and the top ten holders first.
04
How long does an official bridge withdrawal take, and who has to submit the state for it?
