$3.55M in Unclaimed Bridge Funds Moved via EIP-7702 Authorizations

Roughly $3.55 million in unclaimed bridge funds were moved using EIP-7702 account authorizations, security firm BlockSec said. The transactions carried valid account authorizations, but BlockSec said they do not establish whether the wallet owner knowingly approved the transfers. The incident involves funds that had not been claimed on a bridge.

AI take

The notable detail is not the amount but the mechanism: EIP-7702 lets an externally owned account delegate execution to contract code, which turns a dormant, unclaimed balance into something reachable without the owner initiating anything. That shifts the risk profile for idle bridge balances, since the question of consent is now separate from the question of whether the authorization was technically valid. Whether this remains an isolated case or reflects a broader pattern around delegated accounts and stranded bridge funds is the open question.
