Lighter ($LIGHTER) is the native token of Lighter, a decentralized perpetual futures exchange built as a zero-knowledge rollup on Ethereum. The platform generates ZK proofs of all operations, including order matching and liquidations, with proofs verified publicly on Ethereum. Trades are matched by price-time priority, and users retain withdrawal rights through Ethereum as the settlement layer. The token, referred to by the project as the Lighter Infrastructure Token, is designed to align incentives across the platform. Access to Lighter's trading execution and data verification services is tiered based on staking, with staking requirements increasing as the network decentralizes. Users and data providers also pay fees in the token for market data and price confirmation. Half of the total supply is allocated to the ecosystem, including airdrops to participants in the platform's 2025 points seasons, with the remainder allocated to the team and investors under a one-year lock and three-year linear vesting schedule.
