Lighter vs Prism DEX

Lighter is a fully-verifiable decentralized exchange built as a zero-knowledge rollup on Ethereum, delivering high-frequency trading performance with onchain security and composability. Its custom ZK circuits prove every operation — including order matching and liquidations — with millisecond latency and the ability to process tens of thousands of orders per second. The optimized matching engine enables zero fees for retail traders and highly competitive pricing for high-frequency strategies, while deposits, withdrawals and proofs are verified publicly on Ethereum. Lighter's mainnet is live, offering low-cost, low-latency perpetual trading backed by transparent, cryptographically-secured settlement.

Prism is a high-speed decentralized exchange built on MegaETH, designed to provide light-speed swaps, liquidity provision and on-chain trading tools. The protocol leverages Uniswap V3 infrastructure, using contracts such as UniversalRouter, SwapRouter02 and QuoterV2 for routing, quoting and execution. Prism offers curated HTTP endpoints for pool discovery and swap path selection, while quotes are performed directly via RPC reads. Swaps are routed through UniversalRouter by default, optionally through a SelectiveTaxRouter for taxable tokens, with Li.FI used as a fallback for cross-chain or unavailable local routes. The platform also supports concentrated liquidity positions through NonfungiblePositionManager, enabling advanced LP strategies.
