OpenSea Acquires Rally to Enhance Mobile Token Trading

Prominent NFT marketplace OpenSea announced on Tuesday the acquisition of mobile token trading and portfolio management app Rally (previously known as Floor) in a bid to develop “the on-chain everything app.”

As part of this acquisition, Rally co-founders Chris Maddern and Christine Hall—the latter being the former COO at Robinhood Crypto—will be joining OpenSea’s executive team. Maddern will serve as the Chief Technology Officer, while Hall will become OpenSea’s Chief of Staff. Details of the deal were not disclosed.

OpenSea was a major player during the surge in NFT trading in 2021 and 2022. Despite a drop in NFT demand, OpenSea is undergoing a significant transformation this year, rolling out its OS2 platform which includes fungible token trading and announcing support for an upcoming SEA token from the OpenSea Foundation.

Maddern stated, “OpenSea today has hundreds of thousands of active NFT traders with connected wallets who trust OpenSea as their portal to Web3.” He emphasized that the company will work on expanding the types of activities users engage with on OpenSea throughout 2025.

Token trading, according to Maddern, has been “by far our fastest-growing activity.” The recent acquisition positions the platform for continued expansion, particularly focusing on the mobile experience.

Hall mentioned, “We’re reimagining mobile from the ground up to create a product that brings tokens and NFTs together in a magical way—a single home for on-chain crypto on your phone.” She mentioned expectations that while volume will grow more quickly on desktop, mobile will vastly outpace desktop for consumer growth.

Maddern outlined essential areas for creating an everything app for crypto users, which includes simplifying decentralized finance (DeFi) operations and integrating AI.

“Users are looking for a single, simple place to discover and engage with on-chain assets—OpenSea will be that place,” said Maddern. He believes that a mobile-first approach will be crucial for the future of Web3.

Rally began as an NFT portfolio app, allowing users to track their NFT performance through a native mobile app. Initially named Floor, the company raised $8 million in June 2022 and rebranded to Rally in September 2024 to include more on-chain activities like meme coin trading.

In the near future, Maddern confirmed that users could still use the Rally app as usual, with a migration path to the revamped OpenSea mobile experience expected later this year.

OpenSea first launched its mobile app in 2021 amid the NFT trading boom. Recently, it has regained significant lead in Ethereum NFT trading, capturing over 50% market share in the last three months according to data from Tiexo. OpenSea had previously lost market share to competitors such as Blur and Magic Eden.

In February, OpenSea co-founder and CEO Devin Finzer mentioned that the SEC was concluding its investigation into the marketplace regarding the classification of NFTs as securities, adding to a series of inquiries and lawsuits concluded since Donald Trump’s term began.
