Getting Started

$3

Your project needs to use React 17 or later.
For deployment and production use cases, you also need to use Nextjs 12.2 or later to secure the transaction.

$3

In order to make the transaction secure and verify that no one is cheating, play2earn needs to integrate with the backend of Web2To3.
Read the documentation here to see how to create a game and use the API key associated.

$3

Add Play2Earn modal to your project by executing npm install play2earn or yarn add play2earn.

$3

Here's an example of basic usage:

``js
import { Play2EarnModal, finishGameAndGetMoneyWebThree } from "play2earn";
`

`js
gameID={gameID}
playerUID={user?.uid}
handleGameStarting={() => handleGameStarting()}
secondsBeforeCancellation={60} />
`

You also need to add the function which is triggers when the game is starting (i.e after the one/two players have bet in case of
solo/multiplayer game).

`js
async function handleGameStarting() {
console.log('Updating when the second player has accepted the bet.');
// WRITE_YOUR_LOGIC_HERE...
}
`

Then, you need to add the function to end the game when one player has won.

`js
// Call this function when the game is finished with the winnerID
finishGameAndGetMoneyWebThree(process.env.NEXT_PUBLIC_WEBSITE_HOST, gameID, winnerID, winnerID, false)
.then(resultSignature => {
console.log('The money has been transferred to your account, the signature is: ', resultSignature);
});
}
`
