MEASURABLE RESULTS
Business Outcomes for Your AppChain
Our Layer 3 liquidity aggregation service delivers concrete, quantifiable improvements to your application's performance and economics. These are the outcomes you can expect.
01
Enhanced Capital Efficiency
Aggregate liquidity from L2s, L1s, and CEXs into a single, deep pool for your AppChain. This reduces the capital required for market-making by up to 70% and eliminates fragmented liquidity silos.

Layer 3 AppChain Liquidity
Frequently Asked Questions
Get clear answers on how our dedicated liquidity aggregation service accelerates your AppChain's growth.
We deploy a dedicated, permissioned liquidity aggregator directly onto your Layer 3 AppChain. It connects to major DEXs and liquidity sources across Ethereum L2s (Arbitrum, Optimism, Base) and other L3s via cross-chain messaging (like Hyperlane or LayerZero). This creates a single, deep liquidity pool for your native token, enabling seamless swaps and reducing slippage for your users without them leaving your chain.
