From the marginalia, the deposit pathway:

• Deposit confirmations from the claimant to PFx Ltd’s receiving wallet at pfxlt.com.
• Forwarding-wallet pathway documented hop-by-hop with chain of custody hashes.
• Cross-chain bridge transactions where the operator routed value out of the deposit chain.
• Mixer or coin-join interactions, where applicable.
• Final off-ramp at a centralised exchange, the compliance counterparty named in the recovery filing.

Off-ramp reading, exchange counterparty for PFx Ltd:

• PFx Ltd off-ramps consistently to centralised exchanges, Coinbase, Kraken, and Gemini appear less often than the offshore venues; the casefile names the actual endpoint.
• The PFx Ltd 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 PFx Ltd, the packet meets the off-ramp’s published compliance standard.
• When the PFx Ltd off-ramp does not respond, escalation runs through IC3 (for US claimants), state AG, and (above a dollar threshold) civil-discovery overlay.

How a PFx Ltd casefile becomes a evidence filing:

1. Triage on PFx Ltd, submission read against a no-go checklist, written go/no-go returned to the claimant inside one business day.
2. Trace on PFx Ltd, deposit pathway mapped across chains, captured with chain of custody hashes.
3. Identify on PFx Ltd, off-ramp endpoint matched to a named exchange counterparty.
4. File the PFx Ltd 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 PFx Ltd, the Professor stays on the casefile until a documented next step exists.

Reading-list, chains and exchanges in scope:

• Deposit-side chains in PFx Ltd casefiles, typically the major chains (BTC, ETH) and the high-throughput stablecoin chains (Tron USDT, BSC USDT), with bridge crossings noted.
• Off-ramps named in PFx Ltd packets, centralised exchanges that accept regulator-grade compliance filings.
• Filing options on PFx Ltd, IC3 (US), state AG, off-ramp compliance desk, civil-discovery KYC where the dollar value warrants it.
