OpenSea Acquires Rally to Build All-in-One Web3 Mobile Super App

• OpenSea acquires Rally to build a mobile-first Web3 super app combining NFTs, tokens, and DeFi features.
• Chris Maddern becomes CTO of OpenSea, bringing mobile wallet expertise from Rally to lead the product transformation.

OpenSea has acquired Rally, a Web3 startup known for its convenient mobile wallet and social features. Behind this move lies a much grander ambition: to build a single super app that can serve as the hub for all Web3 activities directly from your phone. Imagine a combination of a crypto wallet, NFT platform, tokens, DeFi, and maybe perpetuals, all in one place.

Chris Maddern, who previously led Rally, has now officially been promoted to Chief Technology Officer at OpenSea. Meanwhile, his teammate, Christine Hall, has also joined the executive team. This means this acquisition isn’t just about buying technology, but also buying the brains.

For existing Rally users, there’s a bonus: holders of the “Floor Genesis” NFT will receive a special reward from OpenSea as a token of appreciation.

OpenSea Sets Its Sights on Mobile with Rally Integration

OpenSea has long been known as the number one NFT marketplace. But since the beginning of the year, they’ve started to show signs of increasing agility. One of the most striking steps came with the launch of OS2 in late May—a report from CNF stated that this update streamlined NFT trading across 19 blockchains, eliminating the hassle of token bridges or exchanges.

Furthermore, OS2 also introduced a new XP-based incentive system that encourages organic user activity. And the impact is evident. According to our report in early June, OpenSea reached 467,000 monthly active users in May 2025. That’s the highest number since mid-2023—meaning that, despite the somewhat subdued NFT market, people are still hanging out on the platform.

Now, with Rally in hand, OpenSea appears to be looking to expand that user base into the mobile scene. This applies not only to NFT trading, but also to everything related to tokens, staking, and even DeFi activities. Rally itself is known as an intuitive and mobile-friendly Web3 wallet, so it makes sense that its technology and team would be integrated directly into OpenSea’s grand plans.

Interestingly, OpenSea appears to be increasingly aggressive in embracing the broader blockchain ecosystem. Last March, they also opened the doors to the Ronin Network. Ronin-based NFTs can now be traded directly on OpenSea, and game developers now have simpler tools to build on the network. Whereas previously developers had to juggle backend management, now they can simply focus on ideation and execution.

Furthermore, the Rally acquisition signals that OpenSea wants to break out of the label of “just an NFT marketplace.” They seem to see the potential that in the future, crypto users will need a single, central app—a sort of super app-like hub for their daily activities. And if all goes well, OpenSea plans to launch its new mobile experience before the end of the year.
