Trading pairs

Six markets at launch, all quoted in USDC.e, all backed by Uniswap V3 liquidity on Arbitrum. New listings are gated on real liquidity, not governance votes.

Overview

Every market on Atomic is a leveraged spot pair. Margin is denominated in USDC.e; the asset on the other side is the one you go long or short.

The list is intentionally narrow - Atomic only lists markets where Uniswap V3 on Arbitrum holds enough liquidity to absorb leveraged trades and liquidations without excessive slippage.

Currently listed

MarketAssetMax leverageMin margin
WETH/USDC.eEther20x$25
WBTC/USDC.eBitcoin20x$25
ARB/USDC.eArbitrum15x$25
UNI/USDC.eUniswap10x$50
LINK/USDC.eChainlink10x$50
GMX/USDC.eGMX10x$50

Leverage limits are calibrated per asset to the depth of Uniswap V3 liquidity and the asset's realized volatility. Blue-chip markets (ETH, BTC) carry the full 20x; longer-tail tokens are capped lower so a single liquidation doesn't move the market.

How listings are decided

A market is added when three conditions are met:

  1. Sufficient on-chain liquidity on Uniswap V3 Arbitrum to support leveraged size without breaking the price.
  2. Healthy volume - the asset trades enough that funding the lending pool against it makes sense.
  3. Operational fit - pricing and liquidation flow have been tested against the asset's specific behavior (e.g. tokens with rebases or transfer fees are not eligible).

There is no listing fee, governance vote, or partnership requirement. The protocol is permissioned only by the depth of liquidity behind it.

What's coming

The roadmap prioritizes adding markets that pull traders away from CEX-only listings. Likely next:

  • More L2-native assets as their Arbitrum liquidity matures.
  • Stablecoin pairs for delta-neutral strategies.
  • Long-tail majors (e.g. SOL, AVAX, OP) once routing depth supports them.

Why USDC.e only

Margin is denominated in USDC.e for three reasons:

  • Settlement. USDC.e is the most liquid stablecoin on Arbitrum; closing positions and paying out PnL is fastest.
  • Lending pool. The pool that backs the leveraged portion is denominated in USDC.e, so margining in USDC.e avoids cross-asset risk inside the protocol.
  • Tax simplicity. Reporting PnL in a stable unit is meaningfully easier than in a volatile base.

Native ETH is supported only as a gas-paying asset; trade margin is always USDC.e.
