Phala JS SDK Scaffold

Getting Started

yarn
yarn dev

Important: You must build @phala/sdk before this project (cd ../sdk; yarn build (dev)). Or you can build the two packages together under the monorepo root directory (yarn build (dev)).

Open http://localhost:3000.

Examples

  • Flipper: The UI of the unmodified "flipper" ink! contract.
  • Get IP: The UI of Fat Contract "get-ip".
  • Redeem POAP: The UI of the ETHDenver workshop sample contract. It covers more advanced command and query operations.

Development

To create a new page, it's suggested to copy an existing page (e.g. Redeem POAP), and modify "pages/index.tsx" to add a link.

A page should contain at least a Contract Object to interact with the contract. You can easily create it from <ContractLoader>.

To send a command, get the signer from the framework by the selected account, and then send the transaction with the contract object.

const [account] = useAtom(accountAtom)
const signer = await getSigner(account)
await contract.tx.methodName({}, arg0, arg1, ...)
    .signAndSend(account.address, {signer})

To send a query, a certificate is required.

const certificate = await signCertificate({
    api,
    account,
    signer,
})
// ....
const outcome = await contract.query.methodName(certificateData, {}, arg0, arg1, ...)

Please refer to the Phala SDK Readme for a detailed explanation of the following concepts:

  • contract object
  • command & query
  • certificate
  • and more...
