Arcade Smart Contract

This project implements a Solana-based smart contract designed to manage top users in games. Built using the Anchor framework, it supports features like tracking top scores, managing administrators, and handling in-game payments. This contract is scalable and can be integrated into games to manage player leaderboards and distribute rewards.

Background

This project expands upon the original CW-Arcade smart contract, initially created for a Cosmos-based blockchain. While inspired by its predecessor, it incorporates Solana-specific features, such as streamlined account management and accessible arcade creation, making it even more efficient in terms of space and Solana-specific optimizations. The scoreboard leverages a Sorted Vector instead of a Reversed Binary Heap, simplifying both logic and code readability, resulting in a more robust solution. This Arcade project has already gained attention online and has the potential to establish itself as a new protocol or standard for decentralized arcades, enabling users to deploy and connect their games seamlessly on the Solana blockchain ecosystem.

Features

• Initialize Arcade: Set up a new arcade with administrators, a name, max top scores, and game pricing.
• Play Game: Players can pay to play the game, and their payments are transferred to a prize pool.
• Add Top User: Add players to the top user leaderboard, which ranks players by their score.
• Update Game Price: Modify the cost to play the game at any time.
• Fetch information:

Technologies Used

About Tests

Currently, there is no live dApp utilizing this smart contract, so comprehensive unit tests have been implemented to ensure functionality. These tests cover the following scenarios:

• Initialize Arcade Account

  • ✔ Initializes the arcade account with a PDA

• Play Game

  • ✔ Allows a user to play a game

• Add User Score

  • ✔ Distributes a prize to the user when a new high score is achieved

• Get Arcade State

  • ✔ Retrieves the correct state using get_state functions

Overall, the test suite completes successfully with 4 passing tests.
