EVM Address Checker
Use this EVM address checker to validate Ethereum-compatible addresses, inspect lowercase normalization, and verify whether the address already matches EIP-55 checksum format.
Valid EIP-55 checksum address.
Example Usage
- Check whether a wallet address is a valid EVM hex address.
- Verify if a mixed-case address matches EIP-55 checksum rules.
- Normalize an address before storing or comparing it in a frontend.
EVM Address Checker Explained
An EVM address checker helps you confirm whether an Ethereum-style address is valid before you send funds, store user input, or process blockchain data. The tool checks whether the address is properly formed, whether it can be normalized, and whether its mixed-case form matches the EIP-55 checksum standard. That matters because checksum formatting can catch some typing mistakes that all-lowercase strings would not expose. This is useful for wallets, dashboards, allowlists, smart contract admin tools, and any app that asks users to paste addresses manually.
FAQ
What is an EVM address?
It is a 20-byte hexadecimal address used by Ethereum and other EVM-compatible chains.
What does checksum mean here?
EIP-55 checksum uses letter casing to help detect some address typos.
Are lowercase addresses always invalid?
No. They can still be valid addresses, but they do not carry checksum information.
