Best wallet labeling API on Ethereum

As of June 21, 2026, OLI leads Ethereum coverage rate at 78.0% (p50, 24h window), measured across 4 providers.

Ethereum is the chain where the EOA vs Contract split matters most. On the Contract tab Blockscout saturates near 100% because every Uniswap V3 router, WETH9 and Aave V3 pool ships a verified-source constructor name that the explorer reads for free. On the EOA tab the comparison flips to curated entity graphs: Mobula, Moralis and OLI on Base EAS each maintain their own directory of Binance hot wallets, Safe multisigs, OFAC SDN addresses and public figures. Switch the Kind tab at the top of the page to read the side you actually need.
