From the marginalia, the deposit pathway:

• Deposit confirmations from the claimant to Probtc.online’s receiving wallet at pro-btc.online.
• 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.
