DEXs on Arc blockchain: where to swap on Arc (October 2026)
The main DEXs on Arc blockchain are Uniswap v4, Aero and Curve, with aggregators such as KyberSwap, 0x, 1inch and LI.FI routing across their pools. Every swap pays gas in USDC and is final in under a second. arky, the trading terminal on Circle's Arc chain, routes its spot swaps through KyberSwap.
A fair, sourced list as of 5 October 2026. We list a venue only when Circle, Arc or the venue itself places it on Arc mainnet, and we link that source. We built arky, so we say so where it appears. Listed is not endorsed: check each app's own site before you connect a wallet.
Which DEXs are on Arc blockchain?
Circle's launch press release says "Aero, fomo, and Uniswap anchor Arc's day one trading infrastructure" (Circle, 16 Sept 2026). Curve announced its own Arc launch a day later, and Arc's ecosystem page lists the main aggregators.
| Venue | Type | What you use it for | Source |
|---|---|---|---|
| Uniswap v4 | AMM with hooks | Most token pairs on Arc, including tokens that graduate from launchpads | Uniswap docs, Circle |
| Aero | Liquidity venue | Named by Circle as anchoring day-one trading | Circle |
| Curve | Stablecoin and FX pools (FXSwap) | Swaps between stablecoins and currencies, e.g. USDC and EURC | Curve, 17 Sept 2026 |
| KyberSwap | DEX aggregator | Best route across Arc pools in one transaction; arky's spot router | arc.io/ecosystem |
| 0x, 1inch | DEX aggregators / swap APIs | Routing for wallets and apps | arc.io/ecosystem |
| LI.FI | Cross-chain swap and bridge aggregator | Swapping into Arc from other chains | arc.io/ecosystem |
| fomo | Trading app | Named by Circle as anchoring day-one trading | Circle |
| Launchpad curves (arky, Argus, Bullcheese and others) | Bonding curves or launch pools | Buying new memecoins before or as they reach a DEX pool | Arc ecosystem |
How much volume do Arc DEXs do?
On its first day, 16 September 2026, Arc recorded $410.8 million of DEX volume, and memecoin launchpads drove about 82% of it (Cryptopolitan). That is why the token you want on Arc is often a launchpad token sitting in a Uniswap v4 pool rather than a blue chip. We do not print later volume figures we cannot source.
Is Uniswap on Arc?
Yes. Uniswap v4 is deployed on Arc mainnet: the Uniswap v4 deployments page lists Arc (chain ID 5042) with PoolManager 0x8366a39CC670B4001A1121B8F6A443A643e40951 and Universal Router 0x4fcA4a51Ab4F23A7447b3284fBd7D73289A89Fb1, and we confirmed both hold contract code on 5 October 2026. The integration was announced in June 2026 and went live with mainnet, bringing the v4 AMM, pools, swap routing, SDK and API (Crypto Briefing). Uniswap v4 hooks let launchpads customise pools: Argus uses them for creator buy and sell taxes (Bitcoin Foundation, 29 Sept 2026), and the arky launchpad graduates tokens into a Uniswap v4 pool.
Is Curve on Arc?
Yes. Curve announced "Curve is live on Arc" on 17 September 2026, positioning its FXSwap pools for foreign-exchange markets between stablecoins of different currencies, and offering issuers help with "pool design, simulations and parameter tuning" (Curve news). Use Curve for USDC to EURC style swaps; use Uniswap v4 or an aggregator for memecoins.
Which DEX aggregators support Arc?
KyberSwap, 0x, 1inch and LI.FI are all listed on arc.io/ecosystem, and Circle's launch post names them among partners that "expand access across spot trading, structured products, perpetuals, NFTs, and crosschain execution" (arc.io, 16 Sept 2026). An aggregator splits your order across pools to get a better price than any single pool. arky's spot trading on Arc mainnet routes through KyberSwap.
How do you swap on Arc?
- Add Arc to your wallet with chain ID 5042 (values in Arc network details).
- Get USDC on Arc. Bridge USDC to Arc with Circle CCTP or withdraw from an exchange. USDC is also your gas, so you need nothing else.
- Pick a venue: a DEX, an aggregator or a terminal such as arky.
- Paste the token's contract address from explorer.arc.io or the project's official site, not a token name.
- Set slippage to suit the pool. Thin launchpad pools move a lot on small orders.
- Sign in your wallet. The swap is final in under a second and costs a fraction of a cent in USDC gas at the current 20 gwei base fee.
How do you avoid fake tokens on Arc DEXs?
- Anyone can create a pool, so copies of popular tickers exist. Match the contract address, never the symbol.
- Check liquidity and holders on the explorer before buying; a tiny pool means high price impact and hard exits.
- Be wary of tokens claiming to be "ARC". Circle says no ARC token has been launched (arc.io); see the Arc airdrop facts.
- Revoke old approvals you no longer need.
Can you trade perps on Arc DEXs?
Circle lists perpetuals venues among Arc partners, but arky takes a different route: arky perps on about 35 major cryptos run on Hyperliquid through arky's builder code, with USDC moved between Arc and Hyperliquid over Circle CCTP and leverage capped at 20x by arky.

Where does arky fit among Arc DEXs?
arky is not a DEX; it is the trading terminal of Arc, a screen on top of Arc liquidity. Spot swaps route through KyberSwap, the arky launchpad runs its own bonding curve that graduates to Uniswap v4, and the same app adds crypto prediction markets settled in USDC on Arc and memecoins on Arc discovery. Scout, the AI agent, proposes trades; your wallet signs each one and fills are checked on chain. Compare tools in arky vs Axiom.
