This quick start guide will walk you through deploying and interacting with your own LoyaltyPoint contract. Follow the steps below to set up your loyalty points system quickly.

​

Prerequisites

Before you begin, ensure you have the following tools and dependencies installed:

• Foundry: Install Foundry by following the instructions at https://book.getfoundry.sh/getting-started/installation

​

Contract Deployment

​

Step 1: Clone the Repository

git clone https://github.com/galxe/loyalty-point.git
cd loyalty-point

​

Step 2: Install Dependencies

forge install

​

Step 3: Compile Contracts

forge build

​

Step 4: Deploy your own LoyaltyPoint

Set up necessary environment variables:

FACTORY_ADDRESS=<factory-address>
PRIVATE_KEY=<private-key>
OWNER=<owner-address>
MINTER=<minter-address>

• FACTORY_ADDRESS is the address of the deployed LoyaltyPointFactory contract on the network you are deploying to. For example, on Gravity Alpha Testnet Sepolia, the factory address is 0x8a85eC5AE1ae2c757eEfBb10b1203C984120bf8c.
• PRIVATE_KEY is the private key of the owner address.
• OWNER is the owner address of the LoyaltyPoint contract.
• MINTER is the minter address of the LoyaltyPoint contract.

Run the deployment script:

forge script script/DeployLoyaltyPoint.s.sol:DeployLoyaltyPoint --rpc-url <rpc-url> --broadcast

• rpc-url is the RPC URL of the network you are deploying to. For example, on Gravity Alpha Testnet Sepolia, the RPC URL is https://rpc-sepolia.gravity.xyz.
• Example deployed contract: 0x6B08B2fC665F766193A0cB9a64bcfB8beaac03D4

​

Interacting with the LoyaltyPoint Contract

​

Mint Loyalty Points to user

Using the MINTER address, you can mint loyalty points to a user:

Set up necessary environment variables:

PRIVATE_KEY=<private-key>
LOYALTY_POINT_ADDRESS=<loyalty-point-address>
USER_ADDRESS=<user-address>

• PRIVATE_KEY is the private key of the MINTER address.
• LOYALTY_POINT_ADDRESS is the address of the deployed LoyaltyPoint contract.
• USER_ADDRESS is the address of the user to mint points to.

Run the minting script:

forge script script/MintLoyaltyPoint.s.sol:MintLoyaltyPoint --rpc-url <rpc-url> --broadcast

• Example mint transaction: https://explorer.gravity.xyz/tx/0xc45af104acfc9f33df4a3ab877e114441113ad77cedb7044b789dad506970ac5

​

Conclusion

You’ve successfully deployed your loyalty points system! The LoyaltyPoint contract provides a robust system for minting, burning, and controlling loyalty points for your users, while the factory allows for easy contract creation and management.

Continue by integrating the contracts with your frontend or dApp to offer a seamless user experience.
