Best wallet labeling API on Bitcoin
As of June 21, 2026, WalletExplorer leads Bitcoin coverage rate at 20.0% (p50, 24h window), measured across 1 providers.
Bitcoin wallet labeling is the hardest case in the benchmark because the chain has no smart contract layer to derive names from, every entity has to come from a curated graph. WalletExplorer maintains the canonical public clustering of Bitcoin addresses (exchanges, mixers, pools, OFAC SDN), and most downstream Bitcoin labeling products cite it directly. Mobula audits Bitcoin as part of its universal coverage. The Kind = Contract tab is essentially empty on Bitcoin (no verified-source contracts), so the EOA tab is the only honest comparison.
