Wallet Balance Checker
Check cryptocurrency wallet balance by address. View Bitcoin, Ethereum, Solana balances. See transaction history and token holdings. Real-time blockchain data
Cryptocurrency wallets are public by design — any address's balance can be inspected by anyone on the public blockchain. This is a feature (transparency) and a privacy concern (your transactions are visible forever). This tool looks up balances for Bitcoin, Ethereum, Solana, and other major chains via public block-explorer APIs. It also shows holdings of ERC-20 tokens (USDC, USDT, dai, etc.) and recent transaction history. No login, no wallet integration — paste an address, get the data.
What the lookup actually does
- For Bitcoin: query a public node or block explorer (e.g., Blockstream, Mempool.space) for the address's UTXOs. Sum unspent outputs = balance.
- For Ethereum: query a JSON-RPC node (Infura, Alchemy public endpoints) for the account's ETH balance. For ERC-20 tokens: call each token contract's balanceOf(address) function.
- For Solana: query an RPC node for the account's SOL balance and SPL token accounts.
- For other chains: similar — public RPC endpoints exist for all major blockchains.
- Recent transactions: fetched from the block explorer's recent-history endpoint, typically the last 10-50 transactions.
- Token prices: fiat value computed from current spot prices via a price API (CoinGecko, CryptoCompare).

The address above is a public example (used in many demos). For real privacy, never share your own address publicly with full balance shown — pseudonymity is the only privacy on public blockchains.
Privacy implications
- Every transaction is permanently visible on the blockchain. Sending crypto leaks: source, destination, amount, timing.
- Cluster analysis links addresses — if you ever connected two addresses (sent funds from one to the other, or used both with the same exchange), graph analytics services (Chainalysis, Elliptic) can link them.
- Address-to-identity is the hard part — but if you ever doxxed an address (posted on social media, used at a KYC exchange, accepted from an identified counterparty), the link can propagate.
- Privacy chains (Monero, Zcash, Mina) hide transaction details cryptographically. Privacy mixers (Tornado Cash, Wasabi) attempt to break the link on transparent chains.
- For activities you do not want public, do not use the same address. For activities that should never be linked, use a privacy chain.
When to reach for this tool
- You sent a transaction and want to verify it arrived in the recipient's wallet.
- You want to check the balance of a wallet you control without opening a full wallet client.
- You are doing due diligence on a counterparty's wallet activity (within the limits of public-data analysis).
- You are curious about the blockchain — pick a famous address (Vitalik's, Satoshi's) and see its history.
What this tool will not do
- It will not give you access to the funds. Looking at a balance is reading public data; spending requires the private key (which never leaves the wallet that controls the address).
- It will not identify the owner. Blockchain addresses are pseudonymous; mapping to identity requires off-chain data (KYC records, social media correlations) we do not have.
- It will not detect phishing or hacked-wallet scenarios. A "balance change" without context could be legitimate or theft; the on-chain data does not say which.
- It will not work for private chains (Monero, Zcash shielded). The chain hides the data by cryptographic design; balance lookup is not possible without the viewing key.
Address lookup uses public block-explorer APIs. The queried address is sent to the explorer (who can log it); your IP can be associated with the query. For maximum privacy, run your own node and query locally.
Frequently asked questions
Can I see my entire transaction history?
Yes — every transaction your address has ever sent or received is on the blockchain. Block explorers (Etherscan, Solscan, Blockstream) show the history. Note: balances reported are at the current block; for historical balances at a specific date, special queries are needed.
Why is the balance shown different from my wallet app?
Several possibilities: (1) the wallet shows the sum across multiple addresses; the lookup shows one. (2) Pending transactions not yet confirmed are not in the public balance yet. (3) Token balances depend on which token contracts the wallet recognizes; new tokens may not appear in either.
How accurate is the fiat value?
Spot-priced at the moment of query. Crypto prices change minute-by-minute; the displayed value is a snapshot. For accounting / tax purposes, use timestamps and historical prices.
Can I track transactions in real time?
Block explorers update with each new block (Bitcoin: 10 min, Ethereum: 12 sec, Solana: 400 ms). For real-time monitoring, subscribe to webhooks from a service like Alchemy, QuickNode, or run your own node.
How do I find a Bitcoin address's "owner"?
You generally cannot from blockchain data alone. Identifying an owner requires off-chain data — KYC records at exchanges, social media correlations, surveillance by Chainalysis-type services. Without that, addresses are pseudonymous.
Is the lookup safe?
Reading public blockchain data is safe — does not give anyone access to your funds. Your only privacy concern is that the lookup endpoint (block explorer) logs which addresses are queried from your IP. For privacy-critical lookups, use Tor or run your own node.
