A newly whitelisted contract drained over $6 million in wstETH from a Base vault with seven unnamed signers

Security firms traced about 1,783 wstETH, worth more than $6 million, out of a Base vault on Oct. 4 whose owner is an anonymous 3-of-7 Safe. With Base and Aave's core contracts not blamed, the loss lands on a custody setup whose seven signers no one has publicly identified.

S&P sets out how it will grade the $10 billion on-chain lending vault market

S&P Global Ratings launched a letter-graded risk scale for on-chain lending vaults, a market that grew from $1.5 billion to $10 billion in two years. With no vault graded yet, the method matters first to curators, because S&P counts allocation caps coded into smart contracts as strong risk limits.

Reviewer says Ethereum's ERC-8424 draft for private RWA tokens can leak a hidden balance within 64 calls

Reviewer zexoverz found that two functions in ERC-8424, a draft giving RWA issuers forced transfers over encrypted balances, can leak a balance within 64 calls. OpenZeppelin's own code already limits that view to holders, so the harder gap is rules whose failed transfers expose amounts.

The decimals offset decided whether the victim lost 50 tokens or 4.98

A Foundry fixture runs the same donation attack against two OpenZeppelin vaults, and the depositor ends with zero shares in one and shares worth 45.02 of 50 tokens in the other. In the zero-offset run the attacker burned about 4,975 tokens to cause it.
