Wallet Balance Checker

Paste any address and see its native token balance across 5 chains at once.

Shows each chain’s native token balance only — ERC-20 token balances aren’t included yet.

One address, five chains, one read

The same address can hold funds on Ethereum, BNB Chain, Base, Arbitrum, and Polygon independently — each is a separate ledger. Instead of checking five block explorers, this queries all five public RPCs in parallel and shows the results side by side.

How it works

An eth_getBalance call is made straight from your browser to each chain’s public RPC endpoint — the exact same read a wallet performs when it shows your balance, just across five networks at once instead of one.

Frequently asked questions

No — paste any public address, yours or anyone else's. Wallet addresses and balances are public on-chain data; nothing here requires a signature or connection.

A raw RPC call can only cheaply return the native coin balance directly — enumerating every ERC-20 token an address holds needs an indexing service. That's a planned addition; for now this checks the 5 chains' native tokens (ETH, BNB, POL) at once.

Each chain's public RPC endpoint, queried directly from your browser via eth_getBalance — the same read any wallet or block explorer performs, with no account or backend involved.
