From the marginalia, the deposit pathway:

• Claimant deposit hashes, provided in the case submission and verified against the public ledger for SPG.
• Forwarding wallets on the deposit chain, each hop documented with the forwarding tx hash and the consolidating wallet.
• Bridge events into chains where the operator can off-ramp at scale.
• Mixer or privacy-service interactions, where present, listed with the contract address and the deposit/withdraw side.
• Off-ramp endpoint, the centralised exchange deposit address holding the compliance lever.

The Professor’s off-ramp note:

• SPG’s off-ramp endpoint, in this casefile, is the centralised exchange that holds compliance leverage, typically named in the packet alongside the deposit address.
• Chain-analytics datasets cross-reference the SPG off-ramp wallet against historical laundering throughput.
• The SPG packet is delivered to the off-ramp compliance desk in a format the desk’s reviewers act on.
• Escalation pathways for SPG, where needed: IC3, the relevant state AG, and a civil-discovery overlay for KYC on the off-ramp wallet.

Recovery pathway, how this casefile moves toward filing:

1. Submission triage, SPG casefile reviewed against the no-go list, written reply within one business day.
2. Pathway trace, SPG deposit and forwarding wallets captured.
3. Endpoint identification, SPG off-ramp wallet named.
4. Filing, SPG packet delivered to IC3, state AG, off-ramp compliance, civil discovery as needed.
5. Ongoing follow, SPG stays on file until a documented next step is reached.

Chains and off-ramps the Professor follows:

• Chains the SPG casefile may touch, Bitcoin and Ethereum at the deposit side, Tron USDT-TRC20 in stablecoin pathways, BNB Smart Chain and the L2s (Arbitrum, Optimism, Polygon, Base) where bridges link them.
• Off-ramps relevant to SPG, the major venues including OKX, Bybit, Binance and KuCoin, plus the regional venues operators rotate through under regulatory stress.
• Filings the SPG packet supports, IC3, the appropriate state attorney general, the off-ramp’s compliance desk, and a civil-discovery overlay where dollar value justifies it.

Lines the Professor will not cross:

• Hard line on SPG, no seed-phrase requests, period.
• Hard line on SPG, no remote logins requested.
• Hard line on SPG, no upfront cash retainer.
• Hard line on SPG, no guarantee language.
• Hard line on SPG, no unsolicited phone outreach.
