From the marginalia, the deposit pathway:

• Deposit transaction hashes from the claimant wallet to the MarcoFX 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.

From the lectern, off-ramp identification:

• MarcoFX off-ramps consistently to centralised exchanges, Coinbase, Kraken, and Gemini appear less often than the offshore venues; the casefile names the actual endpoint.
• The MarcoFX off-ramp address is matched to known compliance feeds, the Professor’s standing dataset plus chain-analytics references.
• Compliance leverage is applied at the named counterparty for MarcoFX, the packet meets the off-ramp’s published compliance standard.
• When the MarcoFX off-ramp does not respond, escalation runs through IC3 (for US claimants), state AG, and (above a dollar threshold) civil-discovery overlay.

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

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

Reading-list, chains and exchanges in scope:

• Chains the Professor reads for MarcoFX casefiles, BTC, ETH, Tron USDT, BNB Smart Chain, Avalanche, Polygon, Arbitrum, Optimism, plus the cross-chain bridges that link them.
• Off-ramps named in MarcoFX, major centralised venues with compliance desks that accept regulator-grade packets.
• Filing pathways available on MarcoFX, IC3 for US claimants, state AG offices, off-ramp compliance, and civil-discovery overlay for high-value loss.

Recovery scammers do these things; the Professor never does:

• On the MarcoFX casefile, never request a seed phrase. Ever.
• On the MarcoFX casefile, never request remote-access logins to a wallet or exchange.
• On the MarcoFX casefile, never demand an upfront cash retainer to scope the matter.
• On the MarcoFX casefile, never promise a guaranteed recovery. The trail does not promise one.
• On the MarcoFX casefile, never call the claimant unsolicited. Written-only.
