Check out this composable multi-chain app that seamlessly integrates with any connected blockchain wallet: [BOS SWAP](/#/zavodil.near/widget/swap) Now supports Ethereum (Uniswap), NEAR (Ref Finance) and ZkSync (SyncSwap). Video demo and a little thread on why it is cool on my [tweet](https://twitter.com/zacodil/status/1653734890272088065). 1) ONE blockchain-agnostic frontend code for ALL chains Load composable components for displaying tokens and balances. Connect to a new blockchain with a new connector for [tokens](https://near.org/near/widget/ComponentDetailsPage?src=zavodil.near/widget/TokenData) and [DEXes](https://near.org/near/widget/ComponentDetailsPage?src=zavodil.near/widget/DexData) Use ready-made code or fork if necessary 2) Upon examining the component code, you'll notice that all Ref Finance logic is imported from their own [component](/#/weige.near/widget/ref-swap-getEstimate). I didn't even have to write a function for receiving an estimates or creating swap tx. I got it for free because the Ref had previously written an app for the BOS 3) Token rewards for those who run a decentralised gateway. Gateway hosters can receive referral fees from swaps by providing their account address. Token rewards are available if supported by the DEX, currently live on Ref Finance, and more to come
