Category: Crypto & wallets
Where it runs: Runs locally (nothing you enter is uploaded)

Paste one address, a list, or a whole message. Each address found is matched to its network, its checksum is verified and the normalised form is shown.

## Example input

The first EIP-55 address passes and its copy with one changed capital fails; the lowercase one has no checksum. Both SegWit addresses pass, the Base58 copy with a changed last character fails, the TRON hex becomes T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb and the Solana program ID passes as format only.

## FAQ

### Which addresses and checksums does the validator check?

EVM addresses with EIP-55 mixed-case checksums; Bitcoin, Litecoin and Dogecoin Base58Check addresses (double SHA-256); Bech32 and Bech32m SegWit addresses (BIP-173 and BIP-350); TRON addresses in Base58Check and 41 hex form; and Solana addresses.

### Does a valid checksum mean the address is safe to pay?

No. A checksum only shows that the address was not mistyped or altered; a scammer's address or a poisoned lookalike passes too. Solana addresses and all-lowercase EVM addresses carry no checksum at all, so only their format can be confirmed.

### Is anything sent to a server or a block explorer?

No. Decoding and checksum checks run in your browser, with SHA-256 from the browser's Web Crypto API. The tool does not look up balances, owners or transaction history.
