The annotation reads, wallet trace:

• Deposit transaction hashes from the claimant wallet to the External Coins 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 Professor’s off-ramp note:

• Endpoint counterparty in the External Coins casefile is named, typically a major venue such as OKX or Bybit, sometimes Gate.io or KuCoin, occasionally Binance or Huobi when liquidity allows.
• External Coins’s off-ramp wallet is then matched against compliance feeds the Professor maintains a standing read on.
• Leverage is applied to that named counterparty, the External Coins packet is assembled to a standard the off-ramp’s compliance desk reads and acts on.
• If the External Coins off-ramp is non-cooperative, the casefile escalates to IC3, the relevant state AG, and (where dollar value warrants) a civil-discovery overlay for KYC.

How a External Coins casefile becomes a evidence filing:

1. Submission triage, External Coins casefile reviewed against the no-go list, written reply within one business day.
2. Pathway trace, External Coins deposit and forwarding wallets captured.
3. Endpoint identification, External Coins off-ramp wallet named.
4. Filing, External Coins packet delivered to IC3, state AG, off-ramp compliance, civil discovery as needed.
5. Ongoing follow, External Coins stays on file until a documented next step is reached.

Reading-list, chains and exchanges in scope:

• Chains tracked on External Coins, Bitcoin and Ethereum at the deposit side; Tron USDT-TRC20 and BSC at the consolidation side; bridges crossed where the operator chases liquidity.
• Off-ramps tracked on External Coins, named exchange counterparties with public compliance contacts.
• Filings supported on External Coins, IC3, state AG, off-ramp compliance, civil discovery, selected by the dollar value and the off-ramp’s responsiveness.
