From the marginalia — the deposit pathway:

• Deposit transaction hashes from the claimant wallet to the Yuan Pay Group platform receiving address.
• Forwarding wallets the platform consolidated through — typically two to four hops on the deposit chain (BTC / ETH / USDT-TRC20 / BSC / Polygon / Arbitrum / Optimism / Avalanche).
• Bridge crossings between chains, where the operator moves value into a chain with deeper liquidity ahead of the off-ramp.
• Mixer interactions — Tornado-Cash variants, Sinbad, and the smaller obfuscation services that operators rotate through under regulatory pressure.
• Final off-ramp wallet — the centralised exchange deposit address that received the consolidated funds.

Off-ramp map — where the funds left the chain:

• Off-ramp endpoint for Yuan Pay Group resolves to a named centralised counterparty — the venue varies casefile to casefile, but the resolution always names a real exchange wallet.
• Yuan Pay Group’s off-ramp address is matched against the Professor’s compliance feed and against external chain-analytics datasets.
• The compliance packet for Yuan Pay Group is structured the way an off-ramp compliance reviewer expects to receive evidence — header, hashes, narrative, ask.
• If the Yuan Pay Group off-ramp counterparty does not respond inside the published window, escalation routes through IC3, state AG, and civil discovery.

Filing pathway — the next step after the off-ramp is identified:

1. Triage on Yuan Pay Group — submission read against a no-go checklist, written go/no-go returned to the claimant inside one business day.
2. Trace on Yuan Pay Group — deposit pathway mapped across chains, captured with chain-of-custody hashes.
3. Identify on Yuan Pay Group — off-ramp endpoint matched to a named exchange counterparty.
4. File the Yuan Pay Group packet — IC3, state AG (where loss meets state thresholds), off-ramp compliance desk, and civil-discovery overlay where dollar value supports it.
5. Follow-through on Yuan Pay Group — the Professor stays on the casefile until a documented next step exists.
