Privacy Pools Institutional Integration

Institutions need privacy but fear regulatory backlash from "black box" solutions. Privacy Pools (Buterin et al., 2023) offer a compliance-friendly approach: users can prove their funds don't come from sanctioned sources without revealing transaction history. However, this pattern isn't production-tested for institutional use cases, and lacks integration with institutional wallets and compliance workflows.

RFP: Privacy Pools Institutional Integration

Why It Matters

Provides "compliance-friendly privacy" narrative for regulators
Enables institutions to use privacy without OFAC/sanctions concerns
Creates separation between "privacy" and "money laundering"
Immediately demo-able value for institutional conversations

Scope

In-Scope

Privacy Pools integration for institutional ERC-20 workflows:
- Deposit with association set selection
- Withdrawal with membership/exclusion proofs
- Proof generation for compliance (non-sanctioned source)
Wallet integration design:
- Fireblocks-compatible API surface
- Ledger Enterprise hooks
Compliance proof SDK:
- "Prove funds not from address set X"
- "Prove funds from address set Y" (allowlist)
- Proof verification for counterparties
Association set management:
- How institutions define "clean" sets
- Update mechanisms and governance

Out-of-Scope

Novel cryptographic research (use existing Privacy Pools design)
Full compliance platform
Sanctions list curation (that's a data/legal problem)

Deliverables

Smart contracts for institutional Privacy Pools (auditable)
Proof generation SDK (TypeScript)
Wallet integration spec (Fireblocks/Ledger API surface)
Association set management guide
Example compliance workflow documentation

Dependencies
