| # Approach: Private Delivery-versus-Payment (DvP) | |||
There was a problem hiding this comment.
I think for this one we said private-dvp is not a use case, but something that touches multiple use cases. Do you think it still makes sense as an approach?

| ### Recommended Architecture: Privacy L2 + Atomic Settlement | ||
|
|
||
| **Primary Pattern:** [ERC-7573 DvP](../patterns/pattern-dvp-erc7573.md) |

Is this enough? Do we not need to make this ERC privacy-preserving?
| - EAS attestation logging for audit trails | ||
| - Time-bounded viewing keys for regulatory access | ||

How prescriptive do we want to be at this stage?
Don't think below is bad, just wondering how prescriptive we want to be here at this stage
Also considering trade-offs
E.g. Aztec not live yet, ACE seems a bit diff from atomic settlement, Circle needs to work on L2 etc

| ### Open Questions | ||

| 1. **Stablecoin Issuer Adoption:** Timeline for major issuers (Circle, Tether) to support privacy L2s natively? |

This is great! Some minor comments but think we can merge this; definitely better than what we have right now

I'll go ahead and merge it; can address above in follow up PRs |
