MetaMask Integrates Sei Expanding Access to 100 Million Users

MetaMask, the widely used cryptocurrency wallet with a global user base of over 30 million, has announced a strategic integration with the Sei Network, a high-performance blockchain platform designed to support scalable decentralized applications. This move allows MetaMask users to directly access Sei’s ecosystem without the need for additional tools or intermediaries, enabling cross-chain swaps, asset bridging, and fiat onramps [1]. The integration, which took effect in late July 2025, is part of MetaMask’s ongoing effort to enhance interoperability and simplify user experience across blockchain networks [2].

The Sei Network has officially become one of the 11 blockchains natively supported by MetaMask, offering users a seamless way to interact with Sei’s decentralized finance (DeFi) protocols and dApps. According to the latest on-chain data, Sei has achieved a daily transaction volume of over 4.2 million, a total locked value (TLV) exceeding $600 million, and a monthly active user base of 11 million [3]. With this integration, Sei gains access to over 100 million potential new users, significantly expanding its user reach and ecosystem exposure [4].

Justin Barlow, Executive Director of the Sei Development Foundation, emphasized the strategic importance of the partnership, stating that the integration unlocks Sei’s high-performance blockchain infrastructure for MetaMask users worldwide. He noted that this collaboration provides an unprecedented level of access for Sei’s growing ecosystem, enabling users to interact with the network in a familiar and trusted environment [3]. The addition of a dedicated ecosystem page within MetaMask further enhances the user experience by curating relevant projects and services available on Sei, making it easier for users to explore and engage with the platform [2].

The integration aligns with a broader industry trend toward cross-chain adoption, as users increasingly seek interoperability to optimize utility and reduce costs. Sei, known for its high-speed transactions and low fees, benefits from MetaMask’s extensive user base, which could accelerate the adoption of its network and contribute to a more connected web3 environment [4]. This partnership also underscores MetaMask’s commitment to improving accessibility in the crypto space by expanding support for new blockchains and decentralized protocols [1].

The strategic integration is expected to bring increased liquidity and user activity to the Sei Network. MetaMask users who previously had limited exposure to Sei can now engage with its DeFi protocols, dApps, and tokenized services directly through their existing wallets [5]. This could lead to greater participation and value generation within the Sei ecosystem. Furthermore, the integration may incentivize developers to build on Sei, knowing they can reach a broader audience via MetaMask’s interface [2].

The success of the integration will depend on the optimization of the user experience and the speed at which developers adopt the platform. MetaMask has previously integrated with other blockchains, and historical patterns suggest that a streamlined onboarding process and strong developer support are key factors in driving long-term growth. For Sei, the integration marks a significant milestone in its development as a major player in the blockchain space, leveraging MetaMask’s influence to reach a global audience [1].
