Particle Network is a modular L1 built on the Cosmos SDK, designed to serve as a coordination and settlement layer for cross-chain transactions within a high-performance EVM-compatible execution environment. Its ultimate goal is to unify all on-chain users at the account level, facilitating seamless cross-chain interactions through a single balance and account across L1, L2, or L3, and allowing anyone to easily pay gas fees with any token of their choice.
