How to Check Wallet Balance for Any Crypto (ETH, SOL, BTC)

Whether you're verifying a payment, tracking your portfolio, or checking someone's balance before a trade, knowing how to look up wallet balances is a fundamental crypto skill.

What You Need: Just the wallet address — no login, no API key, no account. Public blockchains are transparent by design. Anyone can query any address's balance at any time.

Ethereum Balance: Use any ETH RPC endpoint — etherscan.io, infura.io, or public RPCs. The balance is stored as Wei (smallest unit). Divide by 10^18 to get ETH. Etherscan shows full transaction history, token holdings, and USD value.

Solana Balance: Solana's RPC API supports getBalance calls. The response is in lamports (divide by 10^9 for SOL). Solscan.io provides detailed account information including SPL token holdings.

Bitcoin Balance: Bitcoin uses UTXO (unspent transaction output) model. The balance is the sum of all unspent outputs. Blockstream.info API provides address balance data. Note: address reuse is discouraged for privacy.
