EscrowClient

@human-protocol/sdk / Modules / escrow / EscrowClient

Class: EscrowClient

escrow.EscrowClient

Introduction

This client enables to perform actions on Escrow contracts and obtain information from both the contracts and subgraph.

Internally, the SDK will use one network or another according to the network ID of the signerOrProvider. To use this client, it is recommended to initialize it using the static build method.

static async build(signerOrProvider: Signer | Provider);

A Signer or a Provider should be passed depending on the use case of this module:

• Signer: when the user wants to use this model in order to send transactions caling the contract functions.

• Provider: when the user wants to use this model in order to get information from the contracts or subgraph.

Installation

npm

npm install @human-protocol/sdk

yarn

yarn install @human-protocol/sdk

Code example

Signer

Using private key(backend)

import { EscrowClient } from '@human-protocol/sdk';
import { Wallet, providers } from 'ethers';

const rpcUrl = 'YOUR_RPC_URL';
const privateKey = 'YOUR_PRIVATE_KEY'

const provider = new providers.JsonRpcProvider(rpcUrl);
const signer = new Wallet(privateKey, provider);
const escrowClient = await EscrowClient.build(signer);

Using Wagmi(frontend)

import { useSigner, useChainId } from 'wagmi';
import { EscrowClient } from '@human-protocol/sdk';

const { data: signer } = useSigner();
const escrowClient = await EscrowClient.build(signer);

Provider

import { EscrowClient } from '@human-protocol/sdk';
import { providers } from 'ethers';

const rpcUrl = 'YOUR_RPC_URL';

const provider = new providers.JsonRpcProvider(rpcUrl);
const escrowClient = await EscrowClient.build(provider);
