Arc is now supported using OpenSea. Starting September 16, 2026, you can buy, sell, and trade assets on Arc, the stablecoin-native Layer-1 blockchain built by Circle, directly using OpenSea on web and OpenSea Mobile. 

What is Arc?

Arc is a stablecoin-native Layer-1 blockchain built by Circle, positioned as an "Economic OS for the internet" and designed as infrastructure for financial markets, real-time money movement, and agentic economic activity. Arc moved to public mainnet on September 16, 2026, after a private mainnet phase with more than 100 ecosystem and institutional builders.

Arc pays network fees in stablecoins, starting with USDC, so costs are designed to maintain a relatively steady value, most often pegged 1:1 to a fiat currency like the U.S. dollar. Transactions are designed to settle in under a second, and the network integrates directly with Circle's platform, including USDC, CCTP, and Gateway, to connect liquidity across chains such as Ethereum and Solana. Arc is built for use cases spanning payments, FX, tokenized real-world assets, lending, and onchain markets.

Arc on OpenSea

OpenSea's goal is to help you trade everything, anywhere, across every chain. Circle built Arc as the settlement layer where stablecoins, tokenized assets, and onchain markets come together. Together, that means Arc assets are now available in the same marketplace you already use across dozens of chains.

From day one using OpenSea, Arc support includes:

• Tokens. Buy, sell, and trade tokens on Arc with OpenSea's aggregated routing, which sources liquidity across decentralized exchanges to find competitive pricing.
• Stablecoins. Buy, sell, and trade stablecoins on Arc, a chain built around stablecoin-native settlement.
• NFTs. Browse, buy, and sell NFT collections on Arc with the full OpenSea toolkit, including floor prices, offers, and collection analytics.
• OpenSea Mobile. Everything above works on OpenSea Mobile, so you can track and trade Arc from your pocket.

How to trade Arc assets using OpenSea

1. Open OpenSea. Go to opensea.io on the web or download OpenSea Mobile from the App Store or Google Play.

2. Connect or create a wallet. OpenSea supports noncustodial wallets, and you can set one up in under a minute.

3. Fund your wallet. Add funds with a card or with crypto. Transacting on Arc uses USDC to pay network fees, so you will want USDC in your wallet.

4. Filter by Arc. Select Arc from the chain filter to browse assets, or search for something specific.

5. Buy, sell, or trade. Your assets stay in your wallet. OpenSea is noncustodial end to end.

Why this matters

As finance moves onchain, the assets people hold are spreading across more networks, and they need one place to find and trade all of it. Arc brings stablecoin-native settlement and real-world financial flows onchain, and OpenSea makes those assets discoverable and tradable alongside everything else you own. A new chain launches, and it is simply available where you already are.
