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.
Usage
This custom hook exposes a mutation function to send a signed transaction to the network.
import { useSendTransaction} from "@trustless-work/escrow/hooks";
/*
* useSendTransaction
*/
const { sendTransaction, isPending, isError, isSuccess } = useSendTransaction();
/*
* It returns a SendTransactionResponse
* payload should be of type string
*/
const data = await sendTransaction(signedXdr);
Description of Return Values
isPending
A boolean status flag indicating whether the mutation is currently in progress. Useful for showing loaders or disabling UI elements during the process.isError
A boolean status flag that becomestrue
if the mutation fails.isSuccess
A boolean status flag that becomestrue
once the mutation completes successfully.
Mutation Function
sendTransaction
This is the main mutation function. Internally, it wrapsmutate
ormutateAsync
and is 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.
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.
Usage Example
import {
useFundEscrow,
useSendTransaction,
} from "@trustless-work/escrow/hooks";
import {
useSomeEndpointPayload
} from "@trustless-work/escrow/types";
export const useSomeEndpointForm= () => {
/*
* useSomeEndpoint
*/
const { someFunction, isPending, isError, isSuccess } = useSomeEndpoint();
/*
* useSendTransaction
*/
const { sendTransaction, isPending, isError, isSuccess } = useSendTransaction();
/*
* onSubmit function, this could be called by form button
*/
const onSubmit = async (payload: useSomeEndpointPayload) => {
try {
// get unsignedTransaction from some endpoint ...
/**
* @Note:
* - We need to sign the transaction using your [private key] such as wallet
* - The result will be a signed transaction
*/
const signedXdr = await signTransaction({ /* This method should be provided by the wallet */
unsignedTransaction,
address: walletAddress || "",
});
if (!signedXdr) {
throw new Error("Signed transaction is missing.");
}
/**
* @Note:
* - We need to send the signed transaction to the API
* - The data will be an SendTransactionResponse
*/
const data = await sendTransaction(signedXdr);
} catch (error: unknown) {
// catch error logic
}
};
}
