From the marginalia — the deposit pathway:

• Claimant-to-platform deposit transactions on the deposit chain used by STB Markets.
• Operator-controlled forwarding wallets where deposits consolidate ahead of laundering or off-ramping.
• Cross-chain bridge events to chains with deeper exchange liquidity.
• Privacy-service interactions, where present in the trail.
• Off-ramp wallet — the named centralised-exchange endpoint.

Off-ramp summary — STB Markets casefile:

• Off-ramp endpoint for STB Markets resolves to a named centralised counterparty — the venue varies casefile to casefile, but the resolution always names a real exchange wallet.
• STB Markets’s off-ramp address is matched against the Professor’s compliance feed and against external chain-analytics datasets.
• The compliance packet for STB Markets is structured the way an off-ramp compliance reviewer expects to receive evidence — header, hashes, narrative, ask.
• If the STB Markets off-ramp counterparty does not respond inside the published window, escalation routes through IC3, state AG, and civil discovery.
