MetaMask has officially announced that it has integrated with Sei Layer-1 blockchain to expand its wallet multichain ecosystem.

According to a report by PR Newswire, MetaMask, has now added Sei Network to its list of integrated blockchains, unlocking cross-chain access to decentralized applications (dApps) for its global user base. X (formerly Twitter) posts from both Metamask and Sei also confirmed the integration.

This addition joins other popular networks already supported by MetaMask, such as Ethereum, BNB Smart Chain, Polygon, Fantom, Arbitrum, Celo, and more, bringing MetaMask’s total supported networks to 11 (eleven).

“Expanding MetaMask to support emerging networks like Sei is about solving real problems for users,” said Gal Eldar, global product lead at MetaMask. “Web3 is moving toward a multi-chain reality, and users shouldn’t have to wrestle with different wallets or complex bridges to participate. By bringing Sei into MetaMask, we’re delivering a smoother and safer experience that we believe will help bring the next wave of users into Web3.”

The integration comes as Sei’s ecosystem experiences significant growth, particularly in decentralized finance. On-chain activity has surged, with daily transactions exceeding 4.2 million and total value locked climbing past $600 million. Meanwhile, Sei’s monthly active users (MAUs) have risen sharply to 11 million.

According to DeFiLlama, Sei’s stablecoin ($SEI) market cap has jumped over 30% in the past seven days, reaching more than $265 million.

“This partnership provides Sei’s growing ecosystem with unprecedented reach while delivering a seamless onboarding experience that users already know and trust. It’s a milestone that takes Sei one step further in building the best high-performance EVM ecosystem.” Justin Barlow, executive director at the Sei Development Foundation, said.

As part of this integration, MetaMask users will now find a dedicated Sei section within the wallet, showcasing Sei-based dApps, games, tokens, NFTs, and other ecosystem highlights. More importantly, users can now natively swap and bridge assets to Sei or even purchase $SEI directly using credit cards or Apple Pay, without needing to leave the wallet interface.

This integration also aligns with MetaMask’s broader push toward a more modular and secure Web3 experience. Recently, MetaMask rolled out its Smart Contract Snaps, a new feature allowing developers to extend wallet functionality with custom plugins. These Snaps support everything from custom transaction insights to enhanced security layers, putting more control in users’ hands while reducing the risks tied to interacting with smart contracts.
