Overview
Zefchain Labs Inc. develops Linera, a layer-1 blockchain using microchains — many small user chains running in parallel for web2-scale throughput and sub-second latency. Founded by Mathieu Baudet, formerly of Meta's Novi wallet team and co-author of the Zef payment protocol research, the company raised $6M seed in June 2022 led by a16z crypto with Cygni Capital, Kima Ventures, and Tribe Capital. A second $6M round in 2023 led by Borderless Capital brought total funding to $12M. Public-facing brand is Linera (linera.io); legal entity remains Zefchain Labs.
Why Zefchain is interesting
Ex-Meta Novi engineer Mathieu Baudet building web2-scale microchains — a16z crypto-led $6M seed, $12M total before Linera brand front-end.
Product & use cases
Linera assigns each user or application a microchain — lightweight chains validated by validators in parallel rather than one global sequential ledger. Targets DeFi and consumer apps needing low latency at scale.
- High-throughput DeFi apps requiring sub-second finality
- Consumer web3 apps needing web2-like responsiveness
- Developer academy and testnet deployments for microchain apps

Competitive landscape
Edge: Baudet's Meta Novi and Zef protocol research pedigree plus a16z's continued support through second round — technical credibility in crowded L1 market.
Post-2022 L1 funding crash left few new chains with capital to ship. Linera's microchain thesis addresses latency; execution risk is mainnet delivery and developer adoption vs. entrenched Solana/ETH L2 ecosystems. $12M total is modest for L1 — capital-efficient roadmap focus.
-
Solana direct
High-throughput L1; Linera different microchain architecture thesis.
-
Aptos / Sui (Move chains) adjacent
Parallel execution L1s; Linera microchain model distinct.
-
Ethereum L2s alternative
Rollups scale Ethereum; Linera standalone L1 bet.
Notable stories
- Baudet published Zef protocol research on sub-second BFT payments before commercializing Linera microchains (arXiv/Zef paper, company lineage).
- Linera name reflects 'linear scaling' ambition — many microchains adding capacity horizontally (Medium launch post).
