Mask Network is a Web3 technology company founded in 2019 by Suji Yan (also known as Yisi Liu). The company is best known for its browser extension that layers decentralized features – encrypted messaging, token transfers, decentralized applications – directly onto mainstream social platforms such as X (formerly Twitter) and Facebook. Beyond its core product, Mask Network operates as a corporate investor, backing early-stage Web3 projects aligned with its decentralized social (DeSoc) thesis.
The company launched its native token $MASK in 2021 via an IEO on Binance Launchpool, which gave it resources to fund ecosystem growth. Mask Network's investment activity focuses on projects that extend Web3 infrastructure into social layers: decentralized identity, NFT tooling, on-chain publishing, and interoperability protocols. Its stated geographic focus spans the United States and broader global Web3 communities, with strong ties to the East Asian developer ecosystem.
Public information about Mask Network's total assets under management or a formal fund size is limited. The company does not operate a named venture fund in the traditional sense – investments appear to be made off the corporate balance sheet or through its ecosystem grant program.

Team
Suji Yan is the founder and chief executive of Mask Network. He previously co-founded Dimension, the parent entity, and has been an active voice in decentralized social media advocacy. He is closely associated with the DeSoc movement alongside researchers including Vitalik Buterin. Public information about other named managing partners or investment team members at Mask Network is limited.
Recent activity
In 2024 and into 2025, Mask Network continued to develop integrations between its browser extension and emerging AI-adjacent Web3 applications. The company has been a vocal proponent of Farcaster and other decentralized social protocols as complementary infrastructure. Mask Network also participated in broader industry discussions around on-chain identity standards. No major fund closes or significant lead investment announcements were publicly reported during this period beyond incremental ecosystem grants.
Mask Network occupies an unusual position – part product company, part ecosystem investor – which makes it harder to evaluate by conventional venture metrics. Its competitive advantage is distribution: the Mask extension gives portfolio projects direct access to a large base of Web3-curious social media users. Whether the company can sustain that edge as native Web3 social platforms such as Farcaster reduce dependency on Web2 rails remains an open question. For investors and founders tracking the DeSoc sector, Mask Network remains a reference point worth watching. Further detail on the company can be found on its official site and via its X account.
