Usage
tronWeb.trx.multiSign(transaction, privateKey, permissionId)
Input Parameters
| Parameter | Description | Data Type |
|---|---|---|
| transaction | The transaction JSON object | JSON |
| privateKey | The signer's private key | String |
| permissionId | Specifies which permission to use. Default is 0, which is the owner permission. | Integer32 |
The parameter permissionId designates the permission type, with Owner ID = 0, Witness ID = 1, and the Active ID incremented from 2 onwards. When the contract is executed, the ID is used to specify which permission to use. For details on Java-Tron permissionId, please refer to the Multi-Signature guide.
Note
The transaction ID changes every time during signing since the permission ID is hashed with the original transaction ID.
Example
const tradeobj = await tronWeb.transactionBuilder.freezeBalance(tronWeb.toSun(100), 3, "ENERGY", "415d73f56d93a9380a100d2a340dd30dc3df6e0746", "415d73f56d93a9380a100d2a340dd30dc3df6e0746", 0);
const signedtxn = await tronWeb.trx.multiSign(tradeobj, privateKey,0);
console.log(signedtxn)
