Examples

EIP1559 (after The London Upgrade)

⚠️

Supported firmware versions T1B1 v1.10.4 and T2T1 v2.4.2

If both parameters maxFeePerGas and maxPriorityFeePerGas are defined, transaction will be signed as the new type introduced in EIP1559.

TrezorConnect.ethereumSignTransaction({
    path: "m/44'/60'/0'",
    transaction: {
        to: '0xd0d6d6c5fe4a677d343cc433536bb717bae167dd',
        value: '0xf4240',
        data: '0xa',
        chainId: 1,
        nonce: '0x0',
        maxFeePerGas: '0x14',
        maxPriorityFeePerGas: '0x0',
        gasLimit: '0x14',
    },
});

Legacy

For T1B1 and T2T1 with firmware older than 2.4.2 (but supported newer firmware versions too).

TrezorConnect.ethereumSignTransaction({
    path: "m/44'/60'/0'",
    transaction: {
        to: '0x7314e0f1c0e28474bdb6be3e2c3e0453255188f8',
        value: '0xf4240',
        data: '0x01',
        chainId: 1,
        nonce: '0x0',
        gasLimit: '0x5208',
        gasPrice: '0xbebc200',
    },
});

Result

        s: string, // hexadecimal string with "0x" prefix
    }
}

Error
