Address Validator
Validate cryptocurrency wallet addresses for Ethereum, Bitcoin, and Solana.
How to Use This Address Validator
This free online address validator lets you instantly check whether a cryptocurrency address is correctly formatted. It supports Ethereum, Bitcoin, and Solana addresses. Follow these steps:
- Paste your address into the input field. The tool accepts Ethereum (0x...), Bitcoin (1..., 3..., bc1...), and Solana addresses.
- View the validation result — the tool instantly checks the format, length, and checksum (where applicable) and displays whether the address is valid.
- Check the address type — the tool identifies whether the address is Ethereum, Bitcoin legacy, Bitcoin SegWit, or Solana.
- Copy the checksummed address for Ethereum addresses to ensure you are using the correct EIP-55 format.
Everything runs locally in your browser. No addresses are sent to any server, making this tool safe for validating addresses holding significant funds.
Common Use Cases
- Pre-transfer validation — Verify addresses before sending any cryptocurrency to avoid irreversible loss of funds.
- Smart contract integration — Validate user input addresses in dApp frontends before passing them to contract calls.
- Checksum conversion — Convert lowercase Ethereum addresses to their EIP-55 checksummed versions for safer storage and display.
- Multi-chain support — Quickly determine which blockchain network an address belongs to based on its format.
- Security auditing — Verify that addresses in configuration files and deployment scripts are valid before going to production.

Frequently Asked Questions
How do I validate an Ethereum address?
A valid Ethereum address is a 42-character hexadecimal string starting with '0x'. This tool checks the format, length, and EIP-55 checksum to ensure the address is correctly formed. Simply paste any address and the tool instantly tells you whether it is valid.
What is EIP-55 checksum validation?
EIP-55 is a mixed-case checksum standard for Ethereum addresses. It uses uppercase and lowercase hex characters to encode a checksum directly into the address string. This helps catch typos and copy-paste errors before you send funds to the wrong address.
Can this tool validate Bitcoin and Solana addresses?
Yes. This tool supports multiple blockchain address formats including Ethereum (0x-prefixed hex), Bitcoin (Base58Check for legacy addresses and Bech32 for SegWit addresses), and Solana (Base58-encoded 32-byte public keys). It automatically detects the address type.
Why should I validate an address before sending crypto?
Cryptocurrency transactions are irreversible. Sending funds to an invalid or mistyped address means permanent loss. Validating addresses before sending ensures the destination is correctly formatted and reduces the risk of losing funds due to typos or clipboard malware.
What is the difference between a valid and a checksummed address?
A valid address has the correct format and length. A checksummed address (EIP-55) additionally encodes error detection into the capitalization of hex characters. An address can be valid in lowercase but fail checksum verification if the mixed-case encoding is incorrect.
