Particle Network
Particle Network is a Singapore-based Web3 infrastructure company building chain abstraction technology so users can interact with any decentralized application on any blockchain from a single account and balance - no bridging or network switching required. Founded in 2022 as a wallet-abstraction provider, it evolved into a modular Layer-1 blockchain that coordinates transactions across chains through its flagship Universal Accounts, Universal Liquidity and Universal Gas products. Its stack has been integrated by hundreds of dApps, helped secure billions in user assets, and reached millions of users; its native PARTI token launched in March 2025.
ZeroDev
ZeroDev is a New York-based B2B blockchain infrastructure company that provides account abstraction wallets as a service. Founded in 2022 by Derek Chiang and backed by Y Combinator (W23), ZeroDev built Kernel — the first modular, extensible smart contract account — enabling developers to ship wallets with social login, gasless transactions, session keys, and transaction batching without seed phrases. By the time of its acquisition by Offchain Labs (Arbitrum's creator) in August 2025, ZeroDev powered 5+ million smart accounts across 130+ EVM-compatible chains for 100+ applications including Gemini, Crossmint, and DIMO.
