Is Blast Safe?
Risk Grade: C (44/100)
Blast is rated as elevated risk — multiple novel mechanisms and notable interaction risks.
High risk — anonymous signers with potential single-entity control over all deposits and no working fraud proof system
An Ethereum Layer 2 network that automatically earns yield on your ETH and stablecoins by staking them behind the scenes. It holds about $200M in deposits and raised $27M in funding. Its C- grade reflects serious concerns: anonymous wallet signers control all deposited money, and there is no working system to catch fraudulent transactions.

Key Risks for Blast Users
Three out of five people who control the wallet holding all deposits are anonymous. Four of their wallets were funded from the same source, so one person may control them all
Your ETH balance changes automatically as yield arrives. Many apps on Blast weren't built for this and can miscalculate what you own, creating exploitable bugs
There is no working fraud proof system. If the operator submits a fake transaction, there is no on-chain way to challenge it. Your money could vanish with no recourse
Top Risk Factors
- •3/5 multisig with unknown signers (4 of 5 funded by same wallet) controlling all deposited assets raises custodial risk
- •Native yield auto-rebasing changes ETH balance semantics, breaking smart contract assumptions across the ecosystem
- •No functional proof system means a malicious proposer can finalize invalid state and cause loss of funds
