OpenSea now supports Arc. Starting September 16, 2026, you can use both the OpenSea web and mobile versions to directly buy, sell, and trade assets on Arc (a stablecoin-native Layer-1 blockchain built by Circle).
What is Arc?
Arc is a stablecoin-native Layer-1 blockchain built by Circle. It is positioned as the “economic operating system of the Internet,” aiming to provide infrastructure for financial markets, real-time fund flows, and agent-driven economic activities. After a private mainnet phase with more than 100 ecosystem and institutional builders, Arc officially launched its public mainnet on September 16, 2026.
Arc uses a stablecoin payment network for fees. It initially used USDC, so costs are designed to maintain relatively stable value—typically pegged 1:1 with fiat currencies such as the US dollar. Transaction settlement is designed to be completed within one second, and the network is directly integrated with Circle’s platform, including USDC, CCTP, and Gateway, connecting liquidity across chains such as Ethereum and Solana. Arc’s use cases include payments, foreign exchange, tokenized real-world assets, lending, and on-chain marketplaces.
Arc on OpenSea
OpenSea’s goal is to help you trade any asset, at any time, anywhere, on any blockchain. Circle builds Arc as the settlement layer that brings together stablecoins, tokenized assets, and on-chain markets—meaning Arc assets can now be traded on the same marketplaces across the dozens of blockchains you already use.
From your first day using OpenSea, Arc support includes:
Tokens are purchased, sold, and traded on Arc through OpenSea’s aggregated routing, which pulls liquidity from decentralized exchanges to find competitive prices.
Stablecoins—buy, sell, and trade stablecoins on Arc. Arc is a blockchain built around native stablecoin settlement.
NFTs—browse, buy, and sell NFT collections on Arc, and use the full OpenSea toolkit, including floor prices, offers, and collection analytics.
OpenSea Mobile. All of the above features are available on OpenSea Mobile, so you can track and trade Arc anytime, anywhere.
How to trade Arc assets on OpenSea
1. Open OpenSea. Visit opensea.io or download OpenSea Mobile from the App Store or Google Play.
2. Connect or create a wallet. OpenSea supports non-custodial wallets, which you can set up in about a minute.
3. Fund your wallet. You can add funds using a debit/credit card or cryptocurrency. Trading on Arc uses USDC to pay network fees, so you’ll need USDC in your wallet.
4. Use Arc filtering to browse assets by selecting Arc from the chain filter, or search for specific content.
5. When you buy, sell, or trade, your assets always stay in your wallet. OpenSea provides end-to-end non-custodial services.
Why this is important
As finance moves on-chain, people’s assets are spread across more networks. They need a unified platform to find and trade everything they own. Arc brings native stablecoin settlement and real-world money flows on-chain, and OpenSea makes these assets discoverable and tradable just like all your other assets. With a new chain live, you can use it anytime, anywhere.
