Cluster and attribute related wallets — funding chains, shared signers, CEX deposit patterns. Use when tracing wallet ownership, comparing two wallets, finding wallet relationships, governance voters, or related address clusters.

Wallet Attribution Answers: "Who controls this wallet? Are these wallets related?" Chain: 0x → chain ethereum (also base, arbitrum, optimism, polygon). Base58 → chain solana . Expansion: Run steps 1 2 on seed. For each new address found, ask the human before querying. Reserve step 3 for seed only. Stop when: known protocol/CEX · Low confidence · already visited · cluster 10 wallets. Confidence: High = first funder / shared Safe signers / same CEX deposit. Medium = coordinated movements / related wallets + label match. Exclude = ENS only, single CEX withdrawal, single deployer. Full attribution rules in REFERENCE.md.
