Examples
EIP1559 (after The London Upgrade)
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',
},
