Contract addresses

Overview

All Atomic contracts are verified on Arbiscan. Source is open and reproducible from the verified bytecode. Treat this page as the authoritative list.

V3 - Arbitrum One

ABIs

ABIs are published in the SDK package at @atomic/sdk/abis. To consume them directly:

import {
AtomicTradingAbi,
AtomicLendingPoolAbi,
AtomicPositionRegistryAbi,
} from '@atomic/sdk/abis';

For non-TypeScript projects, fetch them from Arbiscan's contract page or from the GitHub release artifacts.

V2 - historical reference

V2 contracts are live and operational; new development targets V3. V2 addresses are kept for users with positions opened before V3 launches.

| Contract | Address | |---|---| | AtomicV2Trading | 0x0000…0000 | | AtomicV2LendingPool | 0x0000…0000 |

How to verify a deployment

If you want to confirm an address belongs to Atomic:

1. Check this page. It is the canonical list.
2. Cross-reference Arbiscan. Verified contracts show source matching the published GitHub release.
3. Check the announcement channel. New deployments are announced in the official Discord and on the X account before they go live.
4. When in doubt, do not interact. If a UI prompts you to approve a contract not on this page, stop and ask in Discord.
