Notes

• To load o1js code in your UI, you must set the COOP and COEP headers. These headers enable o1js to use SharedArrayBuffer that o1js relies on to enable important WebAssembly (Wasm) features. Please checkout this link. In the local environment, create a setupProxy.js file inside packages/site/src. You can find the content of the file in the packages/site/src/setupProxy.example.js

• Babel is used for transpiling TypeScript to JavaScript, so when building with the CLI, transpilationMode must be set to localOnly (default) or localAndDeps.

• For the global wallet type to work, you have to add the following to your tsconfig.json:

  {
    "files": ["./node_modules/@metamask/snap-types/global.d.ts"]
  }
