OpenSea adds Solana NFT trading capabilities to OS2

OpenSea introduces Solana NFT trading to the OS2 platform

OpenSea has added Solana NFT trading functionality to OS2, allowing users to access Mad Lads and Claynosaurz series through its multi-chain marketplace.

Summary

OpenSea now allows users to browse, buy, sell and bid on the supported Solana NFT series.

The version released on August 31 expands OS2 's existing Solana services from homogeneous token trading to the NFT domain.

The series available during the initial launch phase include Mad Lads, Claynosaurz, Collector Crypt, and Phygitals.

OS2 now competes more directly with Solana-focused markets such as Magic Eden and Tensor.

OpenSea introduces Solana NFT transactions to OS2

OpenSea said in an August 31 announcement that users can now browse, buy, sell and bid for supported Solana NFT via OS2. This launch includes Mad Lads, Claynosaurz, Collector Crypt and Phygitals and other series built based on the network.

According to the company, users can manage Solana NFT within the same interface without having to change wallets or visit independent markets. Creators using Solana can also put their works on the shelves for OpenSea users who have already traded assets on other blockchains.

Prior to this release, OS2 already supported Solana token trading. The new NFT feature fills the gap in the platform's support for the network, and users can now trade Solana's homogeneous and non-homogeneous tokens simultaneously through one account.

OS2 will be publicly released after a beta period in May 2025 and initially supports 19 chains of token trading. This rebuilt platform also introduces cross-chain capabilities, market aggregation and token support, while retaining NFT products from OpenSea's original business.

As of August 27, OpenSea said its market data has covered more than 25 networks. Four days before the Solana NFT announcement, the company connected its market data to Perplexity Computer, allowing the AI service to answer questions about tokens, collectibles and on-chain trading activity.

OpenSea co-founder and CEO Devin Fenzer described the data used by AI agents as "open, real-time and verifiable" when announcing the integration with Perplexity. The service identifies actively traded assets and series by referencing OpenSea's current real-time activity, rather than relying solely on token price information.

Solana supports intensified competition in the NFT market

For Solana collectors, the release of OpenSea provides them with a new trading venue, who previously relied mainly on markets that have established advantages on the Solana network. Magic Eden initially used Solana as its main platform before expanding to other ecosystems, while Tensor built products around professional Solana NFT traders.

The addition of OpenSea has further increased overlap between markets, although the company has not set transaction volume targets, user forecasts or market share estimates for its Solana products. Its announcement focuses mainly on accessibility to the series and the ability to use existing wallets on supported networks.

This release also restores a service that OpenSea tested years ago. In April 2022, the market introduced Solana NFT support in beta form, making Solana its first non-Ethereum virtual machine network. The new OS2 implementation brings the Solana family back on the platform four years after its first testing.

Competition now goes beyond individual NFT lists, as major markets add networks, wallets and token products to retain users. OpenSea follows this model with OS2, combining its NFT market with homogeneous token trading and products that can capture liquidity from multiple chains.

In July 2025, OpenSea acquired Rally Wallet and acquired a mobile-first wallet business focusing on NFT and tokens. OpenSea plans to integrate Rally's technology into its product line, while Rally co-founder Chris Maddern joins the company as chief technology officer.

OS2 was launched two months before the Rally transaction was completed and has real-time liquidity aggregation and cross-chain capabilities. The wallet acquisition provides OpenSea with another path to develop mobile transactions without separating token activities from NFT portfolio management.

OpenSea continues to expand products beyond NFT

While resuming Solana NFT transactions, OpenSea also continues to develop services outside of its original collectibles market. In June, product director Zack Brenner asked users about early access intentions for perpetual contracts, and later hinted that Hyperliquid might provide infrastructure support.

The planned perpetual contract product will bring OpenSea closer to crypto platforms that combine spot tokens, derivatives and rewards. However, as of the time of report, the company had not announced a release date or final product terms.

Although OpenSea's SEA token release is still delayed, product updates are still moving forward. The company launched SEA in February 2025 and was originally planned to be released around March 30, 2026. The proposed uses include governance, reduced transaction fees and pledges related to the NFT series.

In March, Finzer postponed the launch of the SEA, attributing it to a difficult market environment. OpenSea has not provided a new release date, and users participating in some activities in its Waves rewards program can choose to forgo the relevant Treasure Chest rewards to recover some platform fees.

This token is designed to support OpenSea in building application plans covering NFT, homogeneous assets and other forms of crypto transactions. Solana NFT supported advancing the product level of the plan, but did not change the SEA's undecided timetable.

U.S. regulatory issues still relevant to OpenSea

For U.S. users, Solana NFT's availability came after the U.S. Securities and Exchange Commission concluded its investigation into OpenSea without charging. The agency issued a Wells notice in August 2024 indicating that its staff may recommend enforcement action based on the view that certain NFTs traded in the market may be regarded as securities.

OpenSea said in February 2025 that the SEC had concluded its investigation. Finzer called the decision a victory for the creators of the NFT and argued that treating NFT as securities would distort existing laws.

No law enforcement cases occurred since Wells 'notice, but the conclusion of the investigation did not create a universal exemption for every NFT or market operating in the United States. The legal status of individual digital collectibles may still depend on how they are issued, marketed and sold under U.S. securities laws.

In April 2025, it was previously reported that OpenSea had requested the SEC to clarify that the NFT market should not be regarded as a stock exchange or broker. The company's legal team believes platforms like OpenSea do not execute transactions, hold client assets or act as intermediaries like traditional securities companies.
