Best wallet labeling API on Base

As of June 21, 2026, Blockscout leads Base coverage rate at 70.5% (p50, 24h window), measured across 4 providers.

Base wallet labeling is shaped by Coinbase's OP Stack rollup pattern. Most EVM-centric providers (Mobula, Moralis, Blockscout, OLI via Base EAS) advertise Base coverage and audit cleanly on contracts (Uniswap V4, Aerodrome, the Coinbase Wallet Smart Wallet factory). The EOA tab is the harder job here because Base wallets are dominated by retail Smart Wallets created through the Coinbase Wallet factory, which collapses to a single contract type that providers must distinguish from one another via deployment-time call data.
