Ethereum: get public key

Display requested public key derived by given BIP44 path on device and returns it to caller. User is presented with a description of the requested public key and asked to confirm the export.

const result = await TrezorConnect.ethereumGetPublicKey(params);

Params

Including CommonParams

GetPublicKey

showOnTrezor

Boolean

Optional

determines if address will be displayed on device. Default is set to true

suppressBackupWarning

Boolean

Optional

By default, this method will emit an event to show a warning if the wallet does not have a backup. This option suppresses the message.

chunkify

Boolean

Optional

determines if address will be displayed in chunks of 4 characters. Default is set to false

Bundle(GetPublicKey)

bundle

Array of Objects with above schema

Example

Displays public key derived from BIP44 path:

TrezorConnect.ethereumGetPublicKey({
    path: "m/44'/60'/0'/0",
});

Return a bundle of public keys without displaying them on device:

TrezorConnect.ethereumGetPublicKey({
    bundle: [
        { path: "m/44'/60'/0'/0/0", showOnTrezor: false }, // public key 1
        { path: "m/44'/60'/1'/0/0", showOnTrezor: false }, // public key 2
        { path: "m/44'/60'/2'/0/0", showOnTrezor: false }, // public key 3
    ],
});

    }
}
