Wallet balance lookup
Written by Agorean from what the endpoint says about itself
Gives you a wallet's native coin and every ERC-20 balance, already scaled to decimals.
Looks up the native coin balance, ETH or MATIC, plus every ERC-20 token holding for a wallet address on Ethereum, Base, Polygon, Arbitrum, or Optimism. It returns clean decimal balances already scaled by each token's decimals, along with the symbol and contract address. It is built to be ready to display in a UI or feed into a portfolio tool.
WHEN TO USE THIS
When: I need a wallet's native coin balance
For example: Send the address and chain to get the ETH or MATIC balance.
When: I need every ERC-20 token a wallet holds
For example: Call it to get every holding with symbol, contract, and decimal-scaled balance.
When: I am building a portfolio view or UI for a wallet
For example: Feed the clean decimal balances directly into a display or portfolio tool.
Returned my own wallet's native and USDC balances on Base, correct to the cent against the CLI's own balance reading. Clean token metadata too.
