How to read this diagram
Each station on the rail represents a compliance or infrastructure event in the P2P wallet transfer path. Hover any station to inspect it. The shape tells you what kind of event it is. The ring tells you how it's enforced.

Step 1 · Sender Wallet (Base)Policy-Enforced

"A cash handoff — the sender decides to pay, but unlike a bank transfer, there's no institutional identity gate."

Self-custodial wallet on Base. No KYC gate — the wallet is permissionless. Identity is established only to the extent the wallet provider (MetaMask, Coinbase Wallet, Rainbow) collects it, which for self-custody is typically none. L4 Account and L5 Application lit, but the identity layer is hollow. **Honesty marker:** the D1 (Identity) domain is technically present but not meaningfully enforced.

Step 2 · On-Chain TransferCode-EnforcedINGESTDETECTALERT

"Handing someone cash — the transfer executes, no intermediary screens it, no Travel Rule data accompanies it."

USDC transfers via a single ERC-20 transaction on Base. If the USDC contract's blocklist includes either address, the transfer reverts — this is the only code-enforced compliance gate. No sanctions oracle fires unless the wallet app adds one at the UX layer. L2 Consensus and L3 Execution lit. **Honesty marker:** Stages 3-6 compress because there is no Discovery, no Negotiation, and Authorization is reduced to the USDC blocklist check.

Step 3 · Recipient Wallet (Base)Policy-Enforced

"Receiving cash — the recipient has the funds, but no reporting happened, no Travel Rule data was exchanged, no record exists outside the blockchain itself."

USDC arrives at the recipient's self-custodial wallet. L4 Account and L5 Application lit. **Honesty marker:** D7 (Travel Rule) is listed because FATF Recommendation 16 requires it, but in practice no mechanism exists to transmit originator/beneficiary data in a permissionless self-custodial transfer. This is the structural compliance gap the industry has not solved. Recordkeeping (D11) relies entirely on on-chain transparency — no off-chain report is filed.
