@urls make a webapp that lets users select a chain from a drop down of chains like ethereum, base, spotlight, solana, etc. users should also be able to enter in a contract address. 

the app should validate that the user entered in some text and provide error messages if they did not enter in any text. dont attempt to validate that the text entered is a real smart contract address - simply require that text is entered

there should be a button that the user can tap or click to submit the form. the app should then make a very simple html, javascript, and css app. use a cdn hosted version of viem and create a app that can interact with the methods of the contract. for the sake of this exercise, assume the contract is an ERC721 contract. the webapp you make should make webapps that allow the user to interact with the contract they specified, on the chain they selected, on the contract address they provided (while we assume it is an erc721 contract). have the app dumb the code fot he new app to the console
