From the marginalia — the deposit pathway:

• Deposit transaction hashes from the claimant wallet to the 3XFX 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:

• 3XFX’s off-ramp endpoint, in this casefile, is the centralised exchange that holds compliance leverage — typically named in the packet alongside the deposit address.
• Chain-analytics datasets cross-reference the 3XFX off-ramp wallet against historical laundering throughput.
• The 3XFX packet is delivered to the off-ramp compliance desk in a format the desk’s reviewers act on.
• Escalation pathways for 3XFX, where needed: IC3, the relevant state AG, and a civil-discovery overlay for KYC on the off-ramp wallet.

Recovery pathway — how this casefile moves toward filing:

1. Read the 3XFX submission — written go/no-go returned.
2. Map the 3XFX wallet trail — every hop captured with chain-of-custody hashes.
3. Name the 3XFX off-ramp — endpoint counterparty identified.
4. Build and file the 3XFX recovery packet — to IC3, state AG, off-ramp compliance, civil-discovery overlay.
5. Stay on the 3XFX file — until written next steps exist.

Chains and off-ramps the Professor follows:

• Chains tracked on 3XFX — 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 3XFX — named exchange counterparties with public compliance contacts.
• Filings supported on 3XFX — IC3, state AG, off-ramp compliance, civil discovery — selected by the dollar value and the off-ramp’s responsiveness.
