OpenSea, the non-fungible token (NFT) marketplace, has announced the purchase of Rally, a company known for its mobile tools for Web3 users.

The decision aims to make it easier for people to trade NFTs and tokens directly from their phones.

In a July 8 post on X, OpenSea said, "Buckle up. The future of NFT and token trading fits in your pocket". Rally also shared that users can expect to see the new mobile version of OpenSea "later this year".

Two Rally co-founders, Chris Maddern and Christine Hall, are joining OpenSea’s leadership team. Maddern will assume the role of Chief Technology Officer (CTO).

Both bring knowledge of building mobile platforms for trading digital assets, which OpenSea hopes to use to create what it called an "on-chain everything app".

Maddern explained that OpenSea’s goal is to create a single platform where NFTs and tokens can work together seamlessly, rather than being separate entities. He said the team also wants to make features like decentralized finance tools and futures contracts more user-friendly.

The company said its next steps include releasing a redesigned mobile app by the end of 2025. The updated app is expected to let users buy, sell, and trade NFTs and tokens in one place.
