EthOffline | Transaction Signer

Welcome to EthOffline app, offline Ethereum transaction signing tool.





Please provide your Etheruem private key here, it must be hex '0x...' prefixed (this is not your Bip39 seed or passphrase). A QR code will be prompted if you have entered a valid private key. If your private key is valid, your private key data will be hidden to protect it from any cameras or devices.

If you're using Ian Coleman's Bip39 Tool, open that tool offline. Enter your seed and passphrase, scroll down and copy your Private Key on the right hand side of the page, then paste it above.
