Wallet Address Validator

Validate cryptocurrency wallet addresses with format and checksum verification. Supports Ethereum, Bitcoin, and Solana.

Validate Address

Quick Examples

How It Works

This tool validates cryptocurrency wallet addresses by checking their format, length, character set, and cryptographic checksums. Each blockchain uses a different address encoding scheme with built-in error detection.

Checksum Verification

  • EIP-55 (Ethereum) — Mixed-case hex encoding embeds a checksum via the Keccak-256 hash of the lowercase address. Each alphabetic hex digit is uppercased when the corresponding hash nibble is ≥ 8.
  • Base58Check (Bitcoin) — Legacy addresses include a 4-byte checksum from a double SHA-256 hash, catching typos and transcription errors.
  • Bech32 (Bitcoin SegWit) — Uses a BCH error-detecting code that catches up to 4 character substitutions in addresses up to 89 characters.
