If you’ve ever been stuck waiting for a bank wire to clear while watching the market move without you, you understand the pain of settlement delays. Now imagine that frustration scaled up to institutional-grade vaults holding tokenized real estate loans and other offchain assets, where settlement can take days or weeks. Centrifuge just shipped a fix.
ERC-8161, a new Ethereum standard co-authored by Jeroen Offerijns and Cain O’Sullivan, was proposed in February 2025 and finalized in late July 2026. Its core innovation is deceptively simple: it makes pending deposit and redemption requests transferable before they actually settle. In practice, that means investors no longer have to sit on their hands while waiting for an epoch to close. They can sell their place in line.
What ERC-8161 actually does
To understand why this matters, you need a quick tour of the standards it builds on. ERC-7540, finalized in 2024, introduced asynchronous claim flows for vaults. ERC-7575 added multi-asset support, so a single vault can hold different types of collateral, not just one token.
ERC-8161 is the layer on top. It takes those pending requests created under ERC-7540 and makes them transferable assets in their own right. The standard requires compliance with ERC-165, Ethereum’s interface detection mechanism, ensuring that contracts can verify whether a vault supports transferable requests before interacting with it.
