What problem does it solve? Following money on public blockchains is hard because addresses are pseudonymous, clustering heuristics are probabilistic, and mixers, bridges, and privacy coins break naive tracing. This Skill provides the tradecraft to trace funds correctly, grade findings by confidence, and avoid the attribution errors that produce false accusations. ## Core Features & Use Cases - Address and Transaction Triage: Identify chain and address type from the string format, then read explorers properly including internal transactions, token transfers, and contract bytecode. - Clustering and Flow Analysis: Apply common-input ownership and change-address heuristics with explicit knowledge of their failure modes, and recognize CoinJoin, Tornado-style pools, bridges, and peel chains. - Off-Ramp Identification and Sanctions Screening: Detect exchange deposit structures where KYC records exist, and check addresses against OFAC and other sanctions lists before any interaction. - Use Case: A victim reports paying a ransom to a bc1q address. Trace the payment through a twelve-address cluster to an exchange deposit address, grade each finding as confirmed, probable, or unconfirmed, and hand counsel the deposit address, amount, and block height for legal process. ## Quick Start Trace the Bitcoin address bc1q... from this ransom demand and tell me where the funds went, with each finding graded by confidence.
