From the marginalia — the deposit pathway:

• Initial deposit hashes to the SPX Trade receiving address at spx-trade.org.
• 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 reading — exchange counterparty for SPX Trade:

• Endpoint counterparty in the SPX Trade casefile is named — typically a major venue such as OKX or Bybit, sometimes Gate.io or KuCoin, occasionally Binance or Huobi when liquidity allows.
• SPX Trade’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 SPX Trade packet is assembled to a standard the off-ramp’s compliance desk reads and acts on.
• If the SPX Trade 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.

Recovery sequence — from on-chain reading to filed packet:

1. Casefile review on SPX Trade — reading the submission against the no-go list.
2. Trace mapping on SPX Trade — pathway documented to chain-of-custody standard.
3. Off-ramp naming on SPX Trade — exchange endpoint identified.
4. Packet filing on SPX Trade — to the named off-ramp, IC3, state AG; civil discovery overlay as applicable.
5. Documented follow-through on SPX Trade.

What we read in a SPX Trade casefile:

• Deposit-side chains in SPX Trade casefiles — typically the major chains (BTC, ETH) and the high-throughput stablecoin chains (Tron USDT, BSC USDT) — with bridge crossings noted.
• Off-ramps named in SPX Trade packets — centralised exchanges that accept regulator-grade compliance filings.
• Filing options on SPX Trade — IC3 (US), state AG, off-ramp compliance desk, civil-discovery KYC where the dollar value warrants it.

Lines we never cross — by published policy:

• On the SPX Trade casefile — never request a seed phrase. Ever.
• On the SPX Trade casefile — never request remote-access logins to a wallet or exchange.
• On the SPX Trade casefile — never demand an upfront cash retainer to scope the matter.
• On the SPX Trade casefile — never promise a guaranteed recovery. The trail does not promise one.
• On the SPX Trade casefile — never call the claimant unsolicited. Written-only.
