benfenSignTransaction

Benfen: Sign transaction

Asks device to sign given transaction using the private key derived by given BIP32 path. User is asked to confirm all transaction details on OneKey.

const result = await HardwareSDK.benfenSignTransaction(connectId, deviceId, {
  path: "m/44'/728'/0'/0'/0'",
  rawTx: "0x00000000000200088096980000000000002017f3a9bd36da0639153d3c38032217ea298eb1991e0a62cc5924e2dd712937350202000101000001010300000000010100b4ced58018b75d7ba72a10fa97c09b7bf66533ff104bf9db1bfdb004b17d8eaa0183006eb3c5499c3cb4b022f20955f387312ed312389c552fa39e35d6423d0c74f785b7000000000020497f41fdfb22d2ae32111dcdc21c16d27f48f47b7ca7aba240b684db5ca74c0fb4ced58018b75d7ba72a10fa97c09b7bf66533ff104bf9db1bfdb004b17d8eaa640000000000000060ad38000000000000", // Raw transaction hex
  coinType: "0x2::bfc::BFC"
});

Params

Optional common params
