xrpl_signTransaction

This method is used to sign and submit a transaction to the XRP Ledger (XRPL). Every transaction has the same set of common fields, plus additional fields based on the transaction type. It is expected that the dapp provides all transaction fields defined as required, but not necessarily the auto-fillable.

​
Parameters

  • Object
    • tx_json : Object - (Required) JSON specification of the transaction.
    • autofill : Boolean - (Optional) Defaults to true. Set to false to skip auto-filling parameters.
    • submit : Boolean - (Optional) Defaults to true. Set to false to skip submitting the transaction.
Please note that if you set submit to false, your dapp will need to encode the signed tx_json to the required binary format, before you can send it as tx_blob to an XRPL node using the submit command.

​
Returns

  • Object
    • tx_json : Object - JSON specification of the complete transaction as signed, including any fields that were auto-filled.

​
Example

The example below specifies a simple DEX order for selling 15,000 XRP in exchange for 7,072.8 USD.

xrpl_signTransactionFor

This method is used to add a signature to a multi-signed transaction. The same common fields and transaction types as single-signed transactions are supported.

​
Parameters

  • Object
    • tx_signer : String - (Required) The XRPL address of the signer.
    • tx_json : Object - (Required) JSON specification of the transaction.
    • autofill : Boolean - (Optional) Defaults to false. Set to true to auto-fill parameters.
    • submit : Boolean - (Optional) Defaults to false. Set to true to submit the transaction.
Please note that autofill and submit both defaults to false, since explicit transaction specification and controlled submission is typically needed for multi-signed transactions.

​
Returns

  • Object
    • tx_json : Object - JSON specification of the complete transaction as signed, including any fields that were auto-filled.

​
Example

The example below specifies a multi-signed payment transaction, already signed (in serial) by 3 of 4 required signers. Since only one more signature is required, the optional submit parameter has been set to true.
