Crypto Address Validator

About Crypto Address Validator

The Crypto Address Validator performs real cryptographic checksum verification — not just regex pattern matching — across 12 blockchains. Ethereum and EVM chains are checked with the EIP-55 mixed-case checksum; Bitcoin, Litecoin, Dogecoin, Tron and Ripple use Base58Check (double-SHA256); native SegWit and Taproot use Bech32/Bech32m polymod; Stellar uses CRC16; and Solana addresses are Base58-decoded and required to be exactly 32 bytes. A batch mode validates whole whitelists at once and exports CSV or JSON. Everything runs in your browser — addresses, keys and seed phrases never leave your device.

What is a cryptocurrency address?

A cryptocurrency address is a unique identifier that represents a destination for a cryptocurrency transaction. It's similar to a bank account number and is used to send and receive digital assets on a blockchain network. Each blockchain has its own address format and validation rules.

Why validate cryptocurrency addresses?

Validating addresses before sending cryptocurrency is crucial to prevent loss of funds. An invalid or incorrectly typed address can result in permanent loss of your cryptocurrency. This tool helps ensure the address format is correct and matches the intended blockchain network.

Which blockchains are supported?

This validator supports Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Dogecoin (DOGE), Ripple (XRP), Bitcoin Cash (BCH), Cardano (ADA), Solana (SOL), Polygon (MATIC), Binance Smart Chain (BSC), Tron (TRX), and Stellar (XLM). It recognizes multiple address formats including Legacy, SegWit, Bech32, and EVM-compatible addresses.

How does auto-detection work?

The auto-detection feature analyzes the address format, length, and prefix to determine which blockchain it belongs to. It checks against patterns for all supported blockchains and identifies the most likely match. This is especially useful when you're unsure which network an address belongs to.
