How does Block Street build on-chain stock infrastructure with over ten million dollars led by Hack VC?

What are the core products of Block Street?

Block Street is currently driven by two core products: Aqua Aggregation Layer and Everst Protocol, which together create a unified on-chain stock trading execution layer and lending ecosystem.

Block Street states that Aqua is the industry's first tokenized asset aggregator, which aggregates multiple tokenized stock issuers and market makers, helping users find the cheapest sellers through a price comparison model, allowing them to purchase tokenized stocks or other assets at optimal prices.

Aqua combines off-chain RFQ (Request for Quote) pricing and on-chain EIP-712 signature verification, ensuring transparency and low slippage while simulating the execution speed of traditional markets. Additionally, it optimizes trade routing to reduce maximum extractable value (MEV) leakage, protecting users from malicious activities such as front-running.

Aqua also supports cross-chain interoperability and plans to launch on Monad later this year, followed by expansion to Ethereum, BNB Chain, and Base.

Block Street's other core product, Everst, is a lending protocol designed specifically for tokenized stocks, allowing users to use stocks as collateral for leveraged trading, short selling, hedging, or yield generation. It employs a hybrid liquidation mechanism that supports on-chain auctions and off-chain brokerage routing, suitable for volatile markets, and verifies price accuracy through dual oracles.

The protocol functions like a decentralized stock bank, enabling users to borrow or lend stock assets directly without traditional bank intermediaries, with all operations automatically managed by smart contracts on the blockchain, achieving a transparent, secure, and efficient process.

Moreover, Everst customizes risk models for each tokenized stock, transforming them into productive collateral, and can be integrated into DeFi vaults (e.g., Ondo Finance's yield products). Its hybrid liquidation engine minimizes slippage in high-volatility scenarios, ensuring fast and reliable asset liquidation.

Together, Aqua and Everst build an efficient on-chain stock ecosystem: Aqua provides low-cost, high-speed trade execution, while Everst unlocks the lending potential of tokenized stock assets.

Background of the Block Street Team

Block Street's founder and CEO Hedy graduated from Harvard University and is also an external advisor at Harvard Business School, having led quantitative research at Point72.

Another co-founder, Terrence Wang, is also a co-founder of IOST. He graduated from Princeton University with a master's degree in distributed systems and has years of research experience in cryptocurrency and distributed algorithms, having developed a high-level functional language called Coinlang at Princeton to replace Bitcoin Script.

What opportunities do ordinary users have to participate?

Block Street has launched its testnet. The testnet was first launched on BNB Chain in mid-August 2025, attracting over 200,000 users. On October 9, 2025, the testnet for the Monad network was also officially launched.

The testnet is still running, and users can participate through the points task system (BSD points), which will be converted to the native token $BSD at a 1:1 ratio when the mainnet goes live. The mainnet is expected to launch in the fourth quarter of 2025, and testnet participants are eligible for airdrop rewards.
