useChangeMilestoneStatus

Responsible for modifying the "status" property of a specific milestone in the escrow.

Usage

This custom hook exposes a mutation function to change a custom status the milestone.

import { useChangeMilestoneStatus } from "@trustless-work/escrow/hooks";
import { ChangeMilestoneStatusPayload } from "@trustless-work/escrow/types";

/*
 *  useChangeMilestoneStatus 
*/
const { changeMilestoneStatus, isPending, isError, isSuccess } = useChangeMilestoneStatus();

/* 
 * It returns an unsigned transaction
 * payload should be of type `ChangeMilestoneStatusPayload`
*/
const { unsignedTransaction } = await changeMilestoneStatus(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

changeMilestoneStatus

This is the main mutation function. Internally, it wraps mutate or mutateAsync and handles 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.

ChangeMilestoneStatusPayload: An object with fields necessary to change the milestone status. It is applicable for both single-release and multi-release escrow types.

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: Contains the data required for change milestone status.

Types

Return Value:

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