From the marginalia — the deposit pathway:

• Initial deposit hashes to the Sandai Investment receiving address at sandaiinvestment.com.kh.
• Hop-by-hop forwarding wallets across the deposit chain, captured with chain-of-custody hashes.
• Cross-chain bridge events that move value into the chain where liquidity supports the eventual off-ramp.
• Obfuscation events through mixer contracts and privacy services.
• Centralised-exchange off-ramp wallets — the named counterparty that holds compliance leverage.

Off-ramp map — where the funds left the chain:

• Endpoint counterparty in the Sandai Investment casefile is named — typically a major venue such as OKX or Bybit, sometimes Gate.io or KuCoin, occasionally Binance or Huobi when liquidity allows.
• Sandai Investment’s off-ramp wallet is then matched against compliance feeds the Professor maintains a standing read on.
• Leverage is applied to that named counterparty — the Sandai Investment packet is assembled to a standard the off-ramp’s compliance desk reads and acts on.
• If the Sandai Investment off-ramp is non-cooperative, the casefile escalates to IC3, the relevant state AG, and (where dollar value warrants) a civil-discovery overlay for KYC.

Filing pathway — the next step after the off-ramp is identified:

1. Casefile review on Sandai Investment — reading the submission against the no-go list.
