BOS (Blockchain Operating System) is the easiest way to build and deploy your frontend on-chain by creating a JSX Component. All of the frontend source code on BOS is stored on-chain on Near, making your frontend fully decentralized and open-source. While the frontend is on Near, it can interact with smart contracts on any EVM chain in the backend. Components are also composable, meaning you can reuse and remix different components together and embed them into your dapp.
You are encouraged to incorporate this challenge into your submission for ETHGlobal Istanbul by creating a frontend component for your final project with BOS and deploying it on near.org. You can also build a custom BOS frontend for any existing EVM dapp as your final submission (see examples of BOS components for 1inch, Lido, or Uniswap, for inspiration).
