SOAR is a program that provides a seamless solution for managing leaderboards, achievements, players’ profiles and automatic rewards distribution on the Solana blockchain. Currently supporting invocation from a TypeScript client, the integration in Solana.Unity-SDK will be coming soon.

Quick start

​
Create a new game

import { SoarProgram, GameType, Genre } from "@magicblock-labs/soar-sdk";

// Create a Soar client using the '@solana/web3.js' active Connection and a defaultPayer
const client = SoarProgram.getFromConnection(connection, defaultPayer);

let game = Keypair.generate();
let title = "Game1";
let description = "Description";
let genre = Genre.Action;
let gameType = GameType.Web;
let nftMeta = Keypair.generate().publicKey;
let _auths = auths.map((keypair) => keypair.publicKey);

// Retrieve the bundled transaction.
let { newGame, transaction } = await client.initializeNewGame(
  game.publicKey,
  title,
  description,
  genre,
  gameType,
  nftMeta,
  _auths
);
// Send and confirm the transaction with the game keypair as signer.
await web3.sendAndConfirmTransaction(connection, transaction);

​
Create a leaderboard

const transactionIx = await client.addNewGameLeaderBoard(
  newGame,
  authWallet.publicKey,
  "my leaderboard", // description
  leaderboardNft, // nft associated with the leaderboard
  100,
  true // isAscending
);

await web3.sendAndConfirmTransaction(connection, transactionIx.transaction, [
  authWallet,
]);

​
Submit a score

const score = 10;
const playerAddress = new web3.PublicKey("..."); // The player publicKey
const authWallet = web3.Keypair.fromSecretKey(bs58.decode("")); // AUTH_WALLET_PRIVATE_KEY
const leaderboardPda = new web3.PublicKey(""); // LEADERBOARD_PDA

const transactionIx = await client.submitScoreToLeaderBoard(
  playerAddress,
  authWallet.publicKey,
  leaderboardPda,
  new BN(score)
);

await web3.sendAndConfirmTransaction(connection, transactionIx.transaction, [
  authWallet,
]);

​
Classes

​
SoarProgram

The SoarProgram class gives client access to every instruction in the on-chain SOAR program.

It also gives utility functions for deriving PDAs:

const user = Keypair.generate().publicKey;
const playerAddress = client.utils.derivePlayerAddress(user)[0];

fetching an account:

const account = await client.fetchLeaderBoardAccount(address);

and fetching multiple accounts:

const accounts = await client.fetchAllLeaderboardAccounts([]);

​
GameClient

The GameClient provides a more specific set of functions tailored to a single Game account.

import { GameClient } from "@magicblock-labs/soar-sdk";

Get an instance representing an existing on-chain Game account:

const soar = SoarProgram.getFromConnection(connection, defaultPayer);
const gameClient = new GameClient(soar, address);

Register a new game:

const soar = SoarProgram.getFromConnection(connection, defaultPayer);
const game = new GameClient.register(soar, ...);

// Create a new leaderboard:
await game.addLeaderboard(....);

// Access the game's state.
await game.init();

// Refresh the game's state.
await game.refresh();

// Get the most recently-created achievement for a game
const achievement = game.recentAchievementAddress();

​
InstructionBuilder

import { InstructionBuilder } from "@magicblock-labs/soar-sdk";

The InstructionBuilder provides a set of methods for conveniently bundling transactions.

const transaction = await this.builder
  .andInitializePlayer({ username, nftMeta }, user)
  .andRegisterPlayerEntry(/*...*/)
  .andSubmitScoreToLeaderboard(/*...*/)
  .and(/*some other transaction*/)
  .then((builder) => builder.build());
