Lighter, the Ethereum-based zk-rollup layer 2 built specifically for order-book trading, has integrated with Insilico Terminal, a professional-grade execution management system, in a move designed to attract systematic traders after order-book depth declined following its initial launch period.

What the Insilico integration actually means

The integration allows Insilico users to trade directly on Lighter’s markets from within the Insilico interface, maintaining workflow continuity without switching platforms. Insilico users incur only a 1 basis point terminal fee when trading on Lighter. For non-premium users under certain conditions, there are no additional fees beyond that. Lighter itself charges zero fees for retail traders.

Insilico has reported routing hundreds of millions in perpetual volume through its partner chains over the last 30 days.

The technical edge Lighter is betting on

The platform uses custom ZK circuits for order matching and liquidations. Trades are matched off-chain for speed but verified on-chain through zero-knowledge proofs for security.

Project discussions have referenced a points program with tokens referred to as LIGHT or LIT, though nothing has been formally announced.

What this means for investors and traders

For traders already using Insilico Terminal, the integration provides access to another venue with competitive fees. Lighter’s zero-fee retail model applies regardless of the Insilico partnership.

The broader competitive context includes established perpetual platforms such as dYdX and Hyperliquid. Lighter’s combination of zero-knowledge verification, zero retail fees, and professional trading integrations represents a differentiated architecture within that competitive set.
