From the marginalia — the deposit pathway:

• Deposit transaction hashes from the claimant wallet to the 121Coinx 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.

The annotation continues — off-ramp endpoint:

• Off-ramp endpoint for 121Coinx resolves to a named centralised counterparty — the venue varies casefile to casefile, but the resolution always names a real exchange wallet.
• 121Coinx’s off-ramp address is matched against the Professor’s compliance feed and against external chain-analytics datasets.
• The compliance packet for 121Coinx is structured the way an off-ramp compliance reviewer expects to receive evidence — header, hashes, narrative, ask.
• If the 121Coinx off-ramp counterparty does not respond inside the published window, escalation routes through IC3, state AG, and civil discovery.
