Setup the package in your app

Setup the program:

import { program, transactions } from "@ls-arkade/payments";

const { connection } = useConnection();
const wallet = useWallet();

const lsPaymentsProgram = program(connection, wallet);

Fetch config account

Each game has its own config onchain. See Notion's API doc for more info.

const configAccount = await lsPaymentsProgram.account.configAccount.fetch(
  new PublicKey(DEVNET_WHEEL_OF_FATE_CONFIG_ADDRESS)
);

Fetch pools

You can fetch each pool and display its total vault SOL amount.

import { pda, DAILY_POOL, MONTHLY_POOL, WEEKLY_POOL } from "@ls-arkade/payments";


const [dailyPoolPubkey] = pda.findPoolVault(configAccountKey.publicKey, DAILY_POOL);
const [weeklyPoolPubkey] = pda.findPoolVault(configAccountKey.publicKey, WEEKLY_POOL);
const [monthlyPoolPubkey] = pda.findPoolVault(configAccountKey.publicKey, MONTHLY_POOL);

Buy Paid Arkade SPL token with SOL:

The user can buy Arkade tokens from the UI.

Each tx has a micro fee:

• 0.0044 SOL for each individual ticket tx
• 0.0088 SOL for each pack tx

const sourceTokenAccount = getAssociatedTokenAddressSync(
  configAccount.paymentTokenMint,
  wallet.publicKey!
);

if (!sourceTokenAccount) {
  throw new Error("You don't have enough tokens to start a game.")
}

// Ticket amount can be 1/2/3/4/5 for single tickets or 25/50 for packs
const ticketAmount = 1; 

const buySplTx = await transactions.buySpl(
  new PublicKey(DEVNET_WHEEL_OF_FATE_CONFIG_ADDRESS),
  sourceTokenAccount,
  ticketAmount,
  // new PublicKey("FkgPYryuNgmJepPRDHoFhMo9bAZVSR7D2GQnCjd2AJQ8") // one of the valid NFT held by current player (or undefined)
);

await lsPaymentsProgram.provider.sendAndConfirm(buySplTx, [], { skipPreflight: true });

Start a game:

This methods can be passed an NFT mint belonging to the tx signer.

If the user owns:

• a squirrel: the cost is 1 token
• a "the hallowed": the cost is 2 tokens
• none of the above: the cost is 3 tokens

Final cost is calculated onchain.

const sourceTokenAccount = getAssociatedTokenAddressSync(
  configAccount.paymentTokenMint,
  wallet.publicKey!
);

const sourceTokenAccountInfo = await connection.getAccountInfo(sourceTokenAccount);

if (!sourceTokenAccountInfo) {
  const createATATx = new Transaction().add(createAssociatedTokenAccountInstruction(
    wallet.publicKey!,
    sourceTokenAccount,
    wallet.publicKey!,
    configAccount.paymentTokenMint
  ));
  await lsPaymentsProgram.provider.sendAndConfirm!(createATATx);
}

const handlePaymentTxn = await transactions.handlePayment(
