description: 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

**Requires:**

* Privacy Pools reference implementation
* Institutional wallet API documentation

**Enables:**

* Compliance-friendly privacy deployments
* Regulatory engagement with concrete demo
* Foundation for Travel Rule integration
