What Is Crypto Address Validation?
A bitcoin address validator checks whether a cryptocurrency address is correctly formatted and passes checksum verification before you send funds. Sending crypto to an invalid or mistyped address can result in permanent loss of funds with no way to recover them. Our validator supports multiple blockchains including Bitcoin, Ethereum, and other popular networks, and can auto-detect which chain an address belongs to. It verifies format rules, checksum integrity, and displays address type details. Crucially, your address never leaves your browser — validation runs entirely client-side for maximum privacy.

Why Use Our Crypto Address Validator?
Frequently Asked Questions
Which blockchain networks are supported?
The validator supports Bitcoin (Legacy, SegWit, Bech32), Ethereum (EIP-55 checksum), and other popular networks. Each chain has specific format rules and checksum algorithms that the tool verifies.
Does it auto-detect the blockchain?
Yes. The validator analyzes the address prefix, length, and encoding to automatically identify which blockchain it belongs to. You can also manually select a chain if you prefer.
Is my address sent to a server?
No. All validation logic runs entirely in your browser using JavaScript. Your address is never transmitted to any server, making it safe to check addresses containing significant funds.
Can it check testnet addresses?
Yes. The validator recognizes testnet address formats for supported chains. Testnet addresses use different prefixes than mainnet, and the tool correctly identifies and validates both types.
