Trace summary — funds that left sierrainvest.pro:

• Deposit transaction hashes from the claimant wallet to the SierraInvest 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.

The Professor’s off-ramp note:

• On the SierraInvest casefile, the off-ramp endpoint resolves to a centralised exchange — Bitfinex, MEXC, or Crypto.com seen often in this segment, with the larger venues routed through under stress.
• The off-ramp wallet for SierraInvest is run against chain-analytics datasets and the Professor’s own compliance feeds.
• A regulator-ready packet is delivered to the named counterparty — the SierraInvest casefile is built to the off-ramp’s compliance standard.
• Where the off-ramp will not engage, SierraInvest escalates to IC3, state AG, and civil-discovery overlay.
