FAQ

Overview

Use this as a lookup. Short answers, links into the detail.

General

Do I need to deposit anything?

No. Your wallet balance is the margin. Nothing is held in a protocol vault. See What is Atomic.

What chain does Atomic run on?

Arbitrum One. Bridge USDC.e and a few dollars of ETH for gas. See Quickstart.

Is there a token? Do I need it to trade?

No. Atomic has no governance or utility token. Lender yield is paid in the asset you deposited, out of real trading fees, not in token emissions.

How long has Atomic been live?

Since 2022. 99%+ uptime, no critical security incidents. Contracts audited by Halborn.

Trading

What's the maximum leverage?

20x on every listed market. No minimum position size. See Leverage & margin.

What pairs can I trade?

Right now: WETH, WBTC and ARB against USDC.e; LINK, UNI, CRV and GMX against WETH; plus GMX/USDC. All at 20x max leverage. New pairs get added when Arbitrum DEXes (routed via KyberSwap, 0x and other aggregators) have enough combined depth to support them. See Trading pairs.

What order types are supported?

Market orders for entry and exit, plus Take Profit and Stop Loss on live positions. Setting, editing or cancelling TP/SL is free. See Open a position.

Are there funding rates?

No. Positions on Atomic are real on-chain swaps, not perpetual contracts. The only cost on a position is the 10 bps open + 10 bps close. See Fees & funding.

What's the fee per trade?

10 bps to open + 10 bps to close. 20 bps round trip. For comparison, most perp DEXes charge 50–100 bps.

When does a position get liquidated?

When losses reach 88% of margin. That's one of the deepest thresholds in on-chain perps; Hyperliquid liquidates around 60%. The calculator on Liquidations gives the exact price for any margin and leverage.

What happens if I get liquidated?

A keeper closes the position automatically. After repaying the borrowed capital and fees, whatever's left of the margin (the 12% buffer) goes back to your wallet. On a violent move the residual can be zero - see Liquidations.

Lending

What can I lend?

Any of seven assets: USDC.e, WETH, WBTC, ARB, GMX, LINK or UNI. Each has its own pool with its own APY. Yield is paid in the asset you deposited. See Provide liquidity.

How much can I earn lending?

10–40% APY right now, depending on the pool and on how much trading volume the pool is financing. The yield is paid from real trader fees. See Yield mechanics.

Is there a lockup period?

No. Withdrawals are open at any time, but during high pool utilisation they queue until borrowed capital comes back. Each pool queues independently.

What's the worst case for lenders?

Three things. Smart contract risk; a short withdrawal queue when a pool is fully deployed; and, on the non-stable pools, the price of the underlying asset moving against you while you hold it. The pools stay solvent as long as keepers close positions before they go underwater - that's what the 88% liquidation threshold is for. See Risk model.

Security

Has Atomic been audited?

Yes - by Halborn. Reports are published as they complete. See Audits.

Is there a bug bounty?

A bug bounty program is being prepared and will launch soon. In the meantime, please report anything you find privately to info@atomic.green or via a core contributor on Discord. See Bug bounty.

What if Atomic gets hacked?

For traders: nothing immediate, because there is no vault holding your funds. For lenders: pool capital is what's at risk in a smart contract event - the residual risk Halborn audits and the bounty exist to reduce. See Risk disclosures.

Account & support

Do I need to verify my identity?

No. Atomic is non-custodial. There's no account to KYC.

How do I contact support?
