Getting Started

Get IDEX 2.0 sandbox API keys.

import * as idex from '@idexio/idex-sdk';

const publicClient = new idex.RestPublicClient({
  sandbox: true,
console.log(await publicClient.getServerTime());

In-depth usage documentation by endpoint is available here.


Included in the contracts/ directory are the Solidity source and corresponding ABI for the faucet function for dispensing tokens.

See the idex-contracts repo for a reference Solidity implementation of order and withdrawal signature verification that exactly mirrors the Javascript implementation found in this repo.

The Exchange ABI can be used to query contract state, exit wallets.
