useSendTransaction

Most Trustless Work endpoints return an unsigned transaction in XDR format. This endpoint is used to sign such unsigned transactions and send them to the Stellar network.

This endpoint must be used for all the endpoints after we execute it. Except getEscrowBalances, getEscrowsByContractId, getEscrowsByRole and getEscrowsBySigner .

Usage

This custom hook exposes a function to send a signed transaction to the network.

import { useSendTransaction} from "@trustless-work/escrow/hooks";

/*
 *  useSendTransaction
*/
const { sendTransaction } = useSendTransaction();

/* 
 * It returns a SendTransactionResponse
 * payload should be of type string
*/
const data = await sendTransaction(signedXdr);

Function

• sendTransaction Responsible for building and returning data based on the provided payload.

Argument:

payload: An string containing the required fields to send a transaction to the network.

Types

Return Value:

For: Fund Escrow, Resolve Dispute, Change Milestone Status, Change Milestone Approved Flag, Start Dispute, Release Funds:

• This object will be a type of sendTransactionResponse.

For: Initialize Escrow:

• This object will be a type of sendTransactionResponse. But you can set it as InitializeEscrowResponse.

For: Update Escrow:

• This object will be a type of sendTransactionResponse. But you can set it as UpdateEscrowResponse.
