Deploying the L2 Contract

The Paima L2 Contract is built for developers to deploy their own game as an L2 which seamlessly works with Paima Engine.

In addition to being a core part of infrastructure for the L2 itself, this contract enables developers to earn revenue through collecting fees on every single posted game input. This fee will be held internally in the contract, and can be withdrawn by a specific owner account (which is defined upon deploying the contract).

The owner of the deployed L2 smart contract has the ability to:

  • Set/change the fee
  • Change the owner of the contract to a new address
  • Withdraw collected funds from the contract

Deploying the Contract​

Typically, deploying the L2 contract for your app simply requires running (learn more in the general steps for deploying)

npm run chain:deploy

However, if you want to modify the contract logic, you can use the following in your Hardhat Ignition deploy file

const deploy = m.contract('PaimaL2Contract', [owner, fee]);

Interacting with the L2 Contract via CLI​

Paima comes with some built-in tasks to easily interact with the Paima L2 contract. You can find all these commands by running npx hardhat paima or see the docs in the @paima/evm-contracts NPM package.

This involves everything from withdrawing funds from the contract, changing the owner or changing the fees.

Conclusion​

Congratulations, you have officially deployed your L2 smart contract for your game! You will only need to deploy the contract once, and it will continue to work without any further interactions needed.
