@corwintines or others, would love to get a review of this, think this would be very useful for a lot of people looking at vaults right now. |
Tighten intro, reorder sections, clarify request IDs, add note on optional async flexibility per deposit/redeem.
Simplify prose, remove forward pricing paragraph, weave diagrams into explanatory text instead of standalone headers.
Place the request lifecycle diagram before the deposit/redeem flow details, where it serves as a map for the reader.

Thanks for the well-written page, the diagrams and structure are solid. A few things before this can move forward: Implementation link bias. The Further Reading section links exclusively to Adoption justification. Issue #17911 claims "several billion in TVL" and growing adoption. Could you provide sources for these numbers? For context, the other ERC pages on ethereum.org (ERC-20, ERC-721, ERC-4626, etc.) all document standards with massive ecosystem-wide adoption. Understanding the current adoption scope helps calibrate whether this warrants a standalone page vs. expanding the existing ERC-4626 subsection. SVG dark mode. The diagrams use hardcoded Scope question for maintainers: Does this meet the bar for a standalone page given current adoption, or would expanding the ERC-7540 section on the ERC-4626 page be more appropriate at this stage? Happy to hear other reviewers' take. |
That was unintentional. The ERC4626 Alliance reference implementation is unaudited so not sure it would be best to link to that. There will soon be an OpenZeppelin implementation: OpenZeppelin/openzeppelin-contracts#6399 But that is still in progress. So will remove it for now and suggest we add the OZ one once it's live. |
For TVL specifically, here's a brief overview of TVL based on what I could quickly find.
Besides Centrifuge, there is 1) an increasing number of protocols using it (this list is not complete) and 2) several projects with significant TVL (USDai, Lagoon, Nest, OpenCover). Other references for ecosystem-wide adoption:

Adds page describing ERC-7540 in detail (fixes #17911)
Description
ERC-7540 has grown significantly in adoption, but is a complex standard. While it is already briefly explained on the ERC-4626 page, a more detailed guide specifically for asynchronous vaults can be very useful to a wider audience.
