A couple of significant developments occurred in the past 6-9 months. 
1. Arbitrum launched the Orbit chain, enabling developers to customize aspects such as throughput, privacy, gas token, governance, precompiles, data availability layers, and more. 
2. Uniswap released hooks as part of V4, allowing full customization of Automated Market Makers (AMMs). With V4, projects can inherit the security and reliability of Uniswap and utilize its hooks to customize functionality.

When these enhancements are combined, they enable new types of applications that were previously unfeasible.

By customizing both the chain and the Uniswap AMM, projects can provide a seamless experience for end users, allowing them to use blockchain applications as effortlessly as traditional Web 2 applications.

This grant aims to demonstrate these capabilities and develop a secondary market for startup company stocks. 

The secondary exchange will:

1. Allow all KYC-compliant individuals to add liquidity. This means any employee or existing shareholder can sell their stocks.
2. Enable liquidity addition in only one direction; employees or other shareholders looking to sell will be the sole providers of liquidity.
3. Permit only accredited investors to purchase stocks. These investors will be pre-whitelisted.

Since the Orbit chain is mainnet-ready, yet its tooling is still evolving, and Uniswap V4 has not reached a full code freeze, this grant will concentrate on creating and deploying this application. All of our code will be open source.

Our grant will have two outcomes
1. Developing a real world application which bring the best of DeFi and blockchain to Web2 world
2. Provides a template for other developers on how they can extend both Uniswap and Arbitrum and create their own fully customized decentralized exchanges
