Cartesi Super Soccer

Why the Coprocessor?

With the coprocessor, we can upgrade players' attributes quickly without needing vouchers.

The end user will purchase a pack of 8 soccer players (ERC-721).
Each player will start at a pseudo-random level.
If you're a hacker, you can choose your player's name and get a better starting level.

The match leverages Drand, utilizing knowledge from another project.

At the end of the match, for an AI LLM use case, we compiled the Ollama command line for riscv64.
It was a crazy journey! To achieve this compilation, we fixed numerous bugs related to CPU-only mode,
running it inside the Cartesi Machine with a backdoor to explore and debug errors that only occurred within the CM.
Ollama is a great convenience tool, as you can easily choose from a variety of LLM models. For our case, we chose SmolLM to run it quickly inside the CM.

How to Run Locally

Follow these steps to set up and run the project locally:

1. Deploy the Co-Processor

• Clone and start the dapp-coprocessor.
• Deploy the Co-Processor contract and obtain its deployed address.

2. Configure the Frontend

• Open ./frontend/src/config/Config.ts.
• Set the coprocessorAdapter variable to the deployed Co-Processor contract address.

3. Deploy the NFTPlayers Contract

• Deploy the contract located at onchain/contracts/NFTPlayers.sol.
• Update nftPlayersContractAddress in Config.ts with the deployed contract address.

4. Link the Contracts

After deploying both contracts, call setNFTPlayersContract to link them. You can use the example script below:

const coprocessorAdapter = `0x`; // Replace with deployed Co-Processor contract address
const nftPlayersAddress = `0x`; // Replace with deployed NFTPlayers contract address

const contractABI = [
  {
    "inputs": [{ "internalType": "address", "name": "nftAddress", "type": "address" }],
    "name": "setNFTPlayersContract",
    "outputs": [],
    "stateMutability": "nonpayable",
    "type": "function"
  }
];

const { request } = await createPublicClient({ chain: hardhat, transport: http() }).simulateContract({
    address: coprocessorAdapter,
    abi: contractABI,
    functionName: 'setNFTPlayersContract',
    args: [nftPlayersAddress],
    gas: BigInt(2_000_000),
});

await wallet.writeContract(request);

Note: You can find a working example in ./onchain/scripts/addXp.js.

5. Start the Frontend

Run the following commands to install dependencies and start the frontend:

cd ./frontend
npm install
npm run dev
