useInitializeEscrow

Deploy the escrow contract and define the escrow properties.

Usage

This custom hook exposes a mutation function to deploy an escrow.

import { useInitializeEscrow } from "@trustless-work/escrow/hooks";
import { InitializeEscrowPayload } from "@trustless-work/escrow/types";

/*
 *  useInitializeEscrow 
*/
const { deployEscrow, isPending, isError, isSuccess } = useInitializeEscrow();

/* 
 * It returns an unsigned transaction
 * payload should be of type `InitializeEscrowPayload`
*/
const { unsignedTransaction } = await deployEscrow(payload);

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 becomes true if the mutation fails.

• isSuccess A boolean status flag that becomes true once the mutation completes successfully.

Mutation Function

• deployEscrow This is the main mutation function. Internally, it wraps mutate or mutateAsync and is responsible for building and returning an unsigned transaction based on the provided payload.

Argument:

InitializeEscrowPayload: An object containing the required fields to initialize an escrow.

Types

Return Value:

unsignedTransaction: An object representing the constructed transaction, ready to be signed by your wallet and broadcast.
