OpenSea to support Arc mainnet from day one

September 2, 2026

OpenSea announced it will support Arc from day one when the chain's mainnet goes live on September 16. The partnership positions Arc — built on OP Stack — as the first onchain trading venue launched directly on OpenSea, with users able to trade Arc assets on the marketplace. No other open story covers Arc, so this is a distinct new development.
