What is Atomic?

Overview

Atomic is a deposit-free leveraged trading platform built on Arbitrum. Unlike most on-chain perpetuals, Atomic does not require you to deposit collateral into a smart contract vault.

Positions are routed through DEX aggregators (KyberSwap, 0x) and executed across multiple DEXes. Your wallet balance serves as margin; no deposit step or vault approval required.

How Atomic differs

Most on-chain perpetuals work like a centralized exchange in disguise: you deposit collateral into a vault, the vault tracks your position internally, and you trust the vault to give your money back. Atomic flips this - the trade itself is the on-chain settlement.

The consequences run through the rest of the design:

• Oracle-free pricing. Marks come from on-chain DEX liquidity, not a price feed that can be manipulated or paused.
• Real yield for lenders. Returns are paid from actual trading fees and pool activity, not token emissions. See Lending → Yield mechanics.
• Lower fees. 20 bps round trip vs. the 50–100 bps typical on perpetuals. See Trading → Fees & funding.
• Deeper liquidation buffer. Positions are closed at 88% margin loss vs. ~60% on Hyperliquid. See Trading → Liquidations.
