Free Crypto Wallet Balance Checker

The Crypto Wallet Balance Checker is a free online tool that check ethereum wallet balances on ethereum, bsc, polygon, arbitrum, and optimism using public rpc endpoints. view balance in eth and usd.. It runs entirely in your browser with no installation or sign-up needed.

Ethereum, BSC (Binance Smart Chain), Polygon, Arbitrum, and Optimism.

No — only the native token balance (ETH, BNB, MATIC) is shown. ERC-20 token balances require additional contract calls.

Because this tool reads only the native token of each network — ETH on Ethereum, Arbitrum, and Optimism, BNB on BSC, and MATIC on Polygon. Your wallet app also lists ERC-20 tokens like USDC, USDT, and project tokens, and those are not included here. Reading each ERC-20 requires a separate smart-contract call to that token's address, so the native lookup leaves them out by design. If this checker reports a small or zero figure while your wallet shows funds, that gap is almost always token holdings rather than an error. This is expected behavior, not a bug, and it is why the tool labels the figure as the native token balance for the chain you selected. To see the full picture — every token you hold, plus complete transaction history — open the View on Explorer link after checking a balance and cross-reference there. Enter your address above to confirm the exact native balance in seconds.

No. Every balance on a public blockchain is openly readable, so you only need the wallet address itself — never a private key, seed phrase, or signature. This checker sends a read-only eth_getBalance request to the network and gets back a number; nothing is signed and no transaction is created, so the tool physically cannot move, spend, or touch funds. That is also why you can safely check any address, including one someone sent you that you do not own, before deciding whether to trust it. Avoid pasting a private key into any tool that asks for one to show a balance — a legitimate balance lookup never requires it. Paste a public address above, pick the network, and read the balance with zero risk to the underlying wallet.

After fetching your token balance, the tool makes a second request to the CoinGecko price API for the current USD price of that network's coin, then multiplies it by your balance. CoinGecko reports a market-wide average price, so it can differ slightly from any single exchange, which has its own order book, spreads, and fees. The figure is a live spot estimate at the moment you check, not a guaranteed sale price. The price step is optional: if CoinGecko is rate-limited or unavailable, you still get the exact token balance and the USD column simply shows a dash. So treat the dollar amount as a quick reference rather than a settlement value. Check a balance above to see both the precise token amount and its approximate USD worth side by side.

Blockchains store balances in the smallest possible unit — wei on EVM chains — where one ETH equals 10^18 wei. The network returns that raw integer, and the tool converts it to whole tokens for display. It shows six decimal places so that very small amounts, like dust left over from gas or a tiny test transfer, still appear instead of rounding away to zero. Six places is enough precision to read meaningful balances at a glance while staying compact; the underlying chain tracks far more decimals than that. If you need the exact wei value or want to verify down to the last digit, open the address on its block explorer through the link the tool provides. Paste an address above to see the converted, human-readable balance instantly.

A few things can cause it. First, the address format must be exactly 0x followed by 40 hexadecimal characters — 42 in total; the tool checks this before querying and flags anything truncated or mistyped, which catches the most common mistake. Second, balances are fetched through public Ankr RPC endpoints, which can occasionally be slow, rate-limited, or briefly down, so a retry often resolves a temporary failure. Third, make sure you picked the right network: an address can hold funds on Polygon but show empty on Ethereum if you query the wrong chain. Keep in mind the format check confirms the shape of an address, not that funds exist there, so a perfectly valid address can legitimately return a zero balance with no error at all. Double-check the address you pasted and the selected network above, then run the lookup again.
