Block Street is building a unified liquidity layer for on-chain capital markets, aiming to solve fragmentation and inefficiency in tokenized asset trading. By aggregating liquidity across chains, issuers, and venues, the protocol improves price discovery, execution efficiency, and market depth for tokenized real-world assets.

The ecosystem includes two core systems: Aqua and Everst. Aqua provides cross-chain liquidity routing and RFQ-based execution to reduce spreads and capture arbitrage opportunities, while Everst is a lending and leverage protocol that allows users to borrow and deploy capital against tokenized equities.

At the core of the system is a Hybrid Liquidity Engine that combines off-chain institutional liquidity with on-chain settlement. This dual mechanism improves liquidation efficiency, reduces bad-debt risk, and enables higher capital efficiency for tokenized asset markets.
