From the marginalia, the deposit pathway:

• Deposit confirmations from the claimant to Sadex Group’s receiving wallet at sadexgr.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.

The annotation continues, off-ramp endpoint:

• Sadex Group off-ramps consistently to centralised exchanges, Coinbase, Kraken, and Gemini appear less often than the offshore venues; the casefile names the actual endpoint.
• The Sadex Group 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 Sadex Group, the packet meets the off-ramp’s published compliance standard.
• When the Sadex Group 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. Triage on Sadex Group, submission read against a no-go checklist, written go/no-go returned to the claimant inside one business day.
2. Trace on Sadex Group, deposit pathway mapped across chains, captured with chain of custody hashes.
3. Identify on Sadex Group, off-ramp endpoint matched to a named exchange counterparty.
4. File the Sadex Group 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 Sadex Group, the Professor stays on the casefile until a documented next step exists.

Reading-list, chains and exchanges in scope:

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