Crypto Address Validator

Paste a wallet address to validate its format and identify the chain. Fully client-side — nothing is sent to a server.

Why address validation matters

  • Crypto transactions are irreversible — sending to a wrong address means permanent loss of funds.
  • Format validation confirms the address looks structurally correct for a given chain. It does not confirm the address has ever received funds or that the private key exists.
  • Checksum validation (e.g. EIP-55 for ETH, Base58Check for BTC) provides an extra layer — a typo in a checksummed address will fail the check. This tool detects EIP-55 casing but does not re-verify the keccak hash.
  • Tip: always send a small test transaction first when sending to a new address for the first time.

Supported Chains
