Token balances of an EVM wallet across chains from Blockscout explorers: native coin and ERC-20 holdings with amount, USD price and USD value (largest first), plus per-chain and overall USD totals. Ethereum, Optimism and Gnosis by default; Base, Arbitrum and Polygon when the operator's free Blockscout key is set. Prices are Blockscout's; airdropped tokens can be spam.
