OpenSea adds Solana NFT trading after four-year hiatus. September 3, 2026 Key Takeaways: * Solana NFTs have just been added to OpenSea and users can come and discover them, and trade NFTs from the Solana ecosystem collections. * Added to the launch are noteworthy groups like Claynosaurz, Degen Ape Academy, Solana Monkey Business, Famous Fox Federation and BoDoggos. * The return brings back NFTs to the Solana ecosystem on OpenSea and reintroduces some popular collections to the users' niches. User Score Solana NFTs are back on OpenSea and grant trading partnerships a fresh access to some of the top-notch digital collectible projects on the Solana Blockchain. This announcement is another move by OpenSea to broaden its support of NFTs throughout other blockchain ecosystems. Table of contents. Solana NFTs Arrive on OpenSea. OpenSea has announced that the Solana network is available on its platform for people to browse Solana collections directly on its marketplace. There are some games that are already on Solana launched at the event: Famous Fox Federation, BoDoggos, Claynosaurz, Degen Ape Academy, and Solana Monkey Business. They provide access to a multitude of communities and digital collectibles on Solana for the collector. The integration also allows Solana NFTs to be more discoverable for OpenSea users who may already use OpenSea to explore digital assets outside the Solana network. A return to the marketplace. This is particularly noteworthy as OpenSea has had its toes wet in Solana NFTs before. It was announced as a beta, so the new rollout is actually a great return on the investment Solana made in applying to the platform rather than a launch of the network onto the platform itself. The updated support was included as OpenSea rolls out its extended multichain exchange platform. The platform has not only been supporting NFTs across multiple blockchains but also adding assets from multiple networks. Major Solana collections gained exposure. There are identifiable brands to the Solana NFT space such as Claynosaurz, Degen Ape Academy, Solana Monkey Business, Famous Fox Federation and BoDoggos. These collections will now have their NFTs exposed to a wider population of people using the marketplace, thanks to bringing them onto OpenSea. It is also indicated that it is not restricted to a single collection since this announcement was of its launch. OpenSea is expanding its options in the Solana NFT space by introducing more projects. The development will make it easier to find Solana NFTs and other collectibles on OpenSea for traders. It's another way it can go to potential buyers in projects. The revival of NFTs at OpenSea indicates a rising trend of multichain NFT marketplaces. As it appears that the network is striving to take its place once again in the center of a prominent audience of digital collectibles, with several important Solana collections already available already.

OpenSea brings live onchain market data to Perplexity Computer. August 28, 2026 OpenSea has integrated its cross-chain market data with Perplexity Computer, allowing the AI agent to answer questions about token and NFT trading activity using live data covering more than 25 blockchains. In an announcement shared with crypto.news on Aug. 27, OpenSea said Perplexity Computer can use its marketplace data when users ask about heavily traded tokens, collectibles attracting activity and other onchain market signals. OpenSea gives Perplexity access to live onchain market data. With the connector enabled, Perplexity Computer can pull information directly from OpenSea while carrying out multi-step tasks for users. The integration covers fungible tokens, collectibles and NFTs and allows the AI platform to cite the underlying OpenSea data in its responses. Users can ask which tokens have recorded the most trading activity during a particular period or which assets are drawing attention from traders and collectors. Perplexity can then use OpenSea data to answer based on current marketplace activity instead of relying solely on token price feeds. The companies said the setup gives Perplexity access to data showing what users are buying and trading across OpenSea-supported networks. OpenSea currently provides data across more than 25 chains, giving the AI agent a single source for activity spread across several blockchain ecosystems. "Onchain markets are built for AI agents. Everything is open, live, and verifiable," OpenSea co-founder and CEO Devin Finzer said. Finzer said users were already asking what was moving onchain, while the integration would allow Perplexity Computer to answer those questions using marketplace activity. Perplexity Computer is designed to complete multi-step tasks and provide answers supported by cited sources. Bringing OpenSea into its available data sources extends that model to onchain trading information. "Onchain markets move too quickly for static answers," Perplexity Head of Live Events Products Jeff Grimes said. He added that OpenSea's cross-chain data lets users ask about activity across tokens and collectibles and receive answers based on current market transactions. The OpenSea connector is available through the Connectors page in Perplexity Computer. OpenSea has been expanding beyond NFT trading. The Perplexity deal follows a series of changes that have expanded OpenSea beyond the NFT marketplace business it was originally known for. In June, crypto.news reported that OpenSea was preparing to enter perpetual futures trading using Hyperliquid infrastructure. OpenSea Product Marketing Lead Zack Brenner had asked users on X who wanted early access to perpetual contracts. When another user asked whether Hyperliquid would power the product, Brenner replied "YES." At the time, OpenSea had not released a launch date, complete list of supported assets or user terms for the planned product. The proposed setup would allow the marketplace to use Hyperliquid infrastructure for perpetual contracts as OpenSea extends its trading services outside spot tokens and NFTs. The plan fits into OpenSea's longer-running effort to build what it has described as a "trade everything" platform. OpenSea began taking a larger step in that direction with OS2, an overhaul that combined fungible token and NFT trading across multiple networks. The platform was designed to reduce the need for users to move between separate applications when trading different types of onchain assets. That expansion followed the introduction of OpenSea's native SEA token plans in February 2025. The OpenSea Foundation said historical marketplace activity would factor into allocations and that U.S. users would be eligible. The company later delayed the SEA launch in March 2026, with Finzer citing challenging market conditions. SEA had been expected to play a role in OpenSea's long-term trading platform, with earlier plans covering utility, governance and incentives tied to activity across the ecosystem. OpenSea did not provide a revised launch date when it postponed the token. AI has already featured in OpenSea's product plans. OpenSea had previously placed AI inside its own product roadmap before opening its market data to an external AI agent. In September 2025, the company introduced an AI-powered mobile product alongside changes to its rewards program and plans for its SEA token. The mobile initiative formed part of OpenSea's attempt to combine several types of crypto activity within one product. Its product expansion had already moved the company from a marketplace centered on NFTs toward tokens, mobile trading and other onchain services. Two months earlier, OpenSea acquired Rally Wallet to strengthen its mobile and token trading business. Rally was designed as a mobile-first wallet for NFTs and tokens, and OpenSea planned to integrate the application into its product suite. At the time, OS2 supported trading across 19 blockchains with cross-chain functionality and real-time liquidity aggregation. The latest Perplexity announcement puts the reach of OpenSea's market data at more than 25 chains. Under the new partnership, OpenSea's data will be used outside its own applications when Perplexity Computer responds to questions about market activity. The company said it expects more integrations of this type as AI agents take on a larger role in how users interact with crypto markets.
OpenSea has partnered with Perplexity Computer to integrate its onchain market data into Perplexity's agent platform. The integration allows Perplexity to answer user queries about digital asset trading by accessing OpenSea's real-time data across 25-plus blockchain networks. Users can now ask Perplexity Computer about trending tokens, top assets by market activity, and other onchain signals, with answers drawn directly from OpenSea's marketplace data. The integration covers tokens, collectibles, and NFTs. "Onchain markets are built for AI agents. Everything is open, live, and verifiable," said Devin Finzer, OpenSea's co-founder and CEO. The company expects more AI integrations as agents play a larger role in helping people navigate cryptocurrency markets. The OpenSea connector is available now through Perplexity Computer's Connectors page.
