Wallet trace — what the Professor maps:

• Deposit-side hashes from claimant wallets into Sigma Capital’s receiving addresses.
• Operator forwarding wallets — deposit consolidation documented to chain-of-custody standards.
• Inter-chain bridge transactions when value moves toward off-ramp liquidity.
• Mixer/obfuscation events the operator routed through, where present.
• Final off-ramp endpoint and named counterparty exchange.

The Professor’s off-ramp note:

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