Wallet trace — what the Professor maps:

• Deposit transaction hashes from the claimant wallet to the Diag EX platform receiving address.
• Forwarding wallets the platform consolidated through — typically two to four hops on the deposit chain (BTC / ETH / USDT-TRC20 / BSC / Polygon / Arbitrum / Optimism / Avalanche).
• Bridge crossings between chains, where the operator moves value into a chain with deeper liquidity ahead of the off-ramp.
• Mixer interactions — Tornado-Cash variants, Sinbad, and the smaller obfuscation services that operators rotate through under regulatory pressure.
• Final off-ramp wallet — the centralised exchange deposit address that received the consolidated funds.

Off-ramp reading — exchange counterparty for Diag EX:

• Diag EX casefiles end at a centralised exchange — Bybit, KuCoin, OKX, or Gate.io are common; the casefile names the actual deposit address that received the consolidated funds.
• Off-ramp wallet for Diag EX is matched against compliance and chain-analytics datasets the Professor reads daily.
• Compliance leverage applied to the named off-ramp for Diag EX — the packet is delivered in compliance-desk format.
• Non-cooperative off-ramps trigger IC3 + state-AG + civil-discovery escalation on the Diag EX casefile.

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

1. Read the Diag EX submission — written go/no-go returned.
2. Map the Diag EX wallet trail — every hop captured with chain-of-custody hashes.
3. Name the Diag EX off-ramp — endpoint counterparty identified.
4. Build and file the Diag EX recovery packet — to IC3, state AG, off-ramp compliance, civil-discovery overlay.
5. Stay on the Diag EX file — until written next steps exist.

Reading-list — chains and exchanges in scope:

• Chains the Diag EX 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 Diag EX — the major venues including OKX, Bybit, Binance and KuCoin, plus the regional venues operators rotate through under regulatory stress.
• Filings the Diag EX packet supports — IC3, the appropriate state attorney general, the off-ramp’s compliance desk, and a civil-discovery overlay where dollar value justifies it.
