Out of 8,100+ proposed ERCs, @OpenZeppelin has only implemented a tiny handful of token standards: ERC-20, ERC-721, ERC-1155, ERC-4626, ERC-6909 ERC-7540 is joining that list: the async vault standard is now part of the toolkit most of DeFi runs on.

Tokenized treasuries, private credit, and regulated funds often settle over days, a timeline synchronous onchain vaults weren't designed for. We've merged an implementation of ERC-7540 with support from @tokenizedvault members @centrifuge and @superformxyz to solve this.

Glad to work with @OpenZeppelin and @superformxyz to make it accessible to anyone building real-world assets onchain. A recent piece by @offerijns, CTO of Centrifuge Labs and co-author of ERC-7540, on why real-world assets need async settlement and how the standard delivers it ↓

Beyond Instant Settlement: The Standard for Asynchronous Vaults

The default assumption in DeFi is that everything happens atomically. Deposit tokens, receive shares in the same transaction. Redeem shares, receive tokens back instantly. ERC-4626 codified this into

This is how standards actually earn their spot.

ERC-7540 getting adopted by @OpenZeppelin is a big milestone

What is also notable is that OpenZeppelin has been aware of the ERC-20 design flaw since at least 2018, was reported three separate times, and chose not to document it or act on it. That flaw has caused users to lose over $100 million dexaran.github.io/erc20-loss… They labeled hundreds of ERC-20 contracts as secure while knowing the standard violates basic security design principles
