tronSignTransaction

TRON: Sign transaction

Asks device to sign given transaction. User is asked to confirm all transaction details on OneKey.

const response = await HardwareSDK.tronSignTransaction(connectId, deviceId, params)

Params

Optional common params

• path — required string | Array<number> minimum length is 3. read more
• transaction - required TronTransaction type

TronTransaction Type

type TronTransaction = {
  refBlockBytes: string;
  refBlockHash: string;
  expiration: number;
  data?: string;
  contract: TronTransactionContract;
  timestamp: number;
  feeLimit?: number;
};

type TronTransactionContract = {
  transferContract?: TronTransferContract;
  triggerSmartContract?: TronTriggerSmartContract;
};

type TronTransferContract = {
  toAddress?: string;
  amount?: UintType;
};

type TronTriggerSmartContract = {
  contractAddress?: string;
  callValue?: number;
  data?: string;
  callTokenValue?: number;
  assetId?: number;
};

Example

HardwareSDK.tronSignTransaction(connectId, deviceId, {
    path: "m/44'/195'/0'/0'/0",
    transaction: {
        refBlockBytes: 'ddf1',
        refBlockHash: 'd04764f22469a0b8',
        timestamp: 1655692083406,
        expiration: 1655692140000,
        contract: {
            transferContract: {
                toAddress: 'TXrs7yxQLNzig7J9EbKhoEiUp6kWpdWKnD',
                amount: 100,
            },
        }
    }
});

Result

{
    success: true,
    payload: {
        signature: string;
        serialized_tx: string;
    }
}

Error

{
    success: false,
    payload: {
        error: string, // error message
        code: number // error code
    }
}

Transaction Signing and Broadcasting

// Create the original transaction via TronWeb
const tronWeb = new TronWeb({
    fullHost: 'https://api.trongrid.io'
});
const toAddress = 'TXrs7yxQLNzig7J9EbKhoEiUp6kWpdWKnD'

const encodedTx = await tronWeb.transactionBuilder.sendTrx(
    toAddress,
    1000000
);

//  txid
const txid = encodedTx.txID;

const result = await HardwareSDK.tronSignTransaction(connectId, deviceId, {
    path: "m/44'/195'/0'/0/0",
    transaction: {
        refBlockBytes: encodedTx.raw_data.ref_block_bytes,
        refBlockHash: encodedTx.raw_data.ref_block_hash,
        expiration: encodedTx.raw_data.expiration,
        timestamp: encodedTx.raw_data.timestamp,
        feeLimit: encodedTx.raw_data.fee_limit,
        contract: {
            transferContract: {
                toAddress: toAddress,
                amount: 1000000
            }
        }
    }
});

// rawTx
const rawTx = JSON.stringify({
    txID: txid,
    raw_data: encodedTx.raw_data,
    raw_data_hex: result.payload.serialized_tx,
    signature: [result.payload.signature]
});
