useUpdateEscrow

This endpoint allows you to change the properties of an escrow as long as a series of requirements are met, which will be mentioned in this section.

Usage

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

import { useUpdateEscrow} from "@trustless-work/escrow/hooks";
import { UpdateSingleReleaseEscrowPayload, UpdateMultiReleaseEscrowPayload } from "@trustless-work/escrow/types";

/*
 *  useUpdateEscrow
*/
const { updateEscrow, isPending, isError, isSuccess } = useUpdateEscrow();

/* 
 * It returns an unsigned transaction
 * payload should be of type `UpdateSingleReleaseEscrowPayload` or `UpdateMultiReleaseEscrowPayload`
*/
const { unsignedTransaction } = await updateEscrow(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

updateEscrow

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.

EscrowType: Specifies the type of escrow. It accepts the following values:

• multi-release: Allows for multiple releases of funds.

• single-release: Funds are released in a single transaction.

UpdateSingleReleaseEscrowPayload: An object with fields necessary to update a single-release escrow.

UpdateMultiReleaseEscrowPayload: An object with fields necessary to update a multi-release escrow.

Parameters:

Ensure they match: if you choose a "multi-release" type, you must also use a "multi-release" payload.

• type: Describes the escrow type to be used. Options are "multi-release" or "single-release".

• payload: An object containing the required fields to update an escrow.

Types

Return Value:

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