Allows users to deposit funds into an existing escrow contract, securing them until the agreed conditions are met.
Usage
This custom hook exposes a mutation function to fund and escrow.
import { useFundEscrow } from "@trustless-work/escrow/hooks";
import { FundEscrowPayload } from "@trustless-work/escrow/types";
/*
* useFundEscrow
*/
const { fundEscrow, isPending, isError, isSuccess } = useFundEscrow();
/*
* It returns an unsigned transaction
* payload should be of type `fundEscrow`
*/
const { unsignedTransaction } = await fundEscrow(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 becomestrue
if the mutation fails.isSuccess
A boolean status flag that becomestrue

Mutation Function
fundEscrow
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.
FundEscrowPayload: An object with fields necessary to fund an escrow. It is applicable for both single-release and multi-release escrow types.
Parameters:
type: Describes the escrow type to be used. Options are "multi-release" or "single-release".
payload: Contains the data required for fund escrow.
Return Value:
unsignedTransaction
: An object representing the constructed transaction, ready to be signed by your wallet and broadcast.
Usage Example
import {
useFundEscrow,
useSendTransaction,
} from "@trustless-work/escrow/hooks";
import {
FundEscrowPayload
} from "@trustless-work/escrow/types";
export const useFundEscrowForm = () => {
/*
* useFundEscrow
*/
const { fundEscrow, isPending, isError, isSuccess } = useFundEscrow();
/*
* useSendTransaction
*/
const { sendTransaction, isPending, isError, isSuccess } = useSendTransaction();
/*
* onSubmit function, this could be called by form button
*/
const onSubmit = async (payload: FundEscrowPayload) => {
try {
/**
* API call by using the trustless work hooks
* @Note:
* - We need to pass the payload to the fundEscrow function
* - The result will be an unsigned transaction
*/
const { unsignedTransaction } = await fundEscrow({
payload,
type: "multi-release"
// or ...
type: "single-release"
});
if (!unsignedTransaction) {
throw new Error(
"Unsigned transaction is missing from fundEscrow response."
);
}
/**
* @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);
/**
* @Responses:
* data.status === "SUCCESS"
* - Escrow funded successfully
* - Show a success toast
*
* data.status == "ERROR"
* - Show an error toast
*/
if (data.status === "SUCCESS") {
toast.success("Escrow Funded");
}
} catch (error: unknown) {
// catch error logic
}
};
