Builders: SDK, MCP and API

SDK

One ES module served by this site. Reads go through the public API; writes return calldata for your own wallet.

import { PerpHook } from "https://<this site>/sdk/elyperps.js";
const ph = new ElyPerps("https://<this site>");
const { markets } = await ph.markets();
const q = await ph.quote({ engine: markets[0].engine, isLong: false, lev: 2, margin: "1" });
const tx = ph.openCalldata({ engine: markets[0].engine, isLong: false, lev: 2, margin: "1" });
// tx = { to, data, value }: sign it with your wallet
