ERC-8161 Transfers Pending Redemptions

Centrifuge has co-authored ERC-8161, a new Ethereum standard designed to resolve the issue of pending vault redemptions. This problem occurs when users are stuck in redemption queues waiting for their assets to settle.

The existing ERC-7540 standard introduced the concept of splitting vault operations into separate request and claim steps. However, it did not address the issue of transferring pending requests. ERC-8161 builds on this foundation by making pending requests transferable.

This new standard enables the creation of secondary markets for redemption queues. A user who needs immediate liquidity can transfer their pending redemption claim to a counterparty willing to wait, likely at a small discount.

Centrifuge's track record with async vault design has been significant, particularly with its Tinlake platform, which introduced epoch-based request queuing for illiquid real-world assets. The progression from Tinlake's epoch-based model to ERC-7540's request-claim split to ERC-8161's transferable pending positions represents a logical evolution.

ERC-8161 requires ERC-165 and ERC-7540 for implementation, making it designed to slot cleanly into the existing vault architecture. This new standard is expected to simplify restructuring operations by allowing pending positions to be delegated to new addresses or operators.
