**Grant Proposal: Private P2P Bridge – Universal L2 Privacy for P2P Trading**

We’re building **Private P2P Bridge** , a relayer-based bridge that brings privacy to cross-L2 stablecoin trades. The system locks USDC on Base, moves zk-USDC through Aztec for private execution, and releases USDC to Arbitrum.

**How It Works:**

- Merchants list P2P trades across L2s.
- Buyers initiate escrowed transactions, fully private on Aztec.
