API & on-chain access
Everything on Arclight is on-chain and open. Read it directly from Arc today; a hosted REST API arrives with the indexer for fast, cached data.

ABIs ship with the app under web/app/lib/abis. Every pool address comes from getLaunches on the launchpad.
Read on-chain (available now)
Any EVM library works. Example with viem:
import { createPublicClient, http } from "viem";
import { launchpadAbi } from "@arclight/abis";
const client = createPublicClient({
transport: http("https://arc-testnet.drpc.org"),
});
// newest-first launches
const launches = await client.readContract({
address: "0x69c6aD4a7aD1D713535059cF2Bb27313789Ee90A",
abi: launchpadAbi,
functionName: "getLaunches",
args: [0n, 24n],
});
Per pool you can read reserveUsdc, reserveToken, realUsdc, gradThreshold, graduated, and quote a trade with quoteBuy / quoteSell.
REST API soon · with indexer
A hosted, cached API (planned at api.arclightpad.app) will serve everything the UI uses — no rate-limited RPC needed. Planned endpoints:
- GET /v1/launches — all beacons, newest first
- GET /v1/token/{pool} — price, raised, progress, status
- GET /v1/token/{pool}/trades — points of light (buys/sells)
- GET /v1/token/{pool}/holders — top holders + supply share
- GET /v1/beaconharbor/feed — posts, tiers, boosters
- GET /v1/leaderboards — most reposted & most volume
Fair-data promise: the API only ever returns verifiable on-chain data — never fabricated volume, holders, or prices.
