esolidar Sweepstake Contracts

Deploy

Clone the repository and install dependencies.

Important: use npm version 16!

npm install

Create the .env file based on .env.example file.

cp .env.example .env

Edit the .env file. It's necessary to get the wallet's private key. The wallet must have CELO to deploy the contracts.

# CELO
ALFAJORES_ADDRESS_PK=
CELO_ADDRESS_PK=

Testnet (Alfajores)

First, deploy the contracts.

npx hardhat --network alfajores deploy

And verify them in blockchain explorer.

npx hardhat --network alfajores sourcify

Mainnet (CELO)

First, deploy the contracts.

npx hardhat --network celo deploy

And verify them in blockchain explorer.

npx hardhat --network celo sourcify

Contract configurations

It's necessary, after deployment, to set on the ERC721 contract the Sweepstake contract address.

Edit the scripts/configure-contract.js to check if the tokenURI suffix, default is ipfs:// (line 17).

npx hardhat --network (alfajores|celo) run script/configure-contracts.js

Contract ABIs

Web3 uses the ABI file to interact with the contract. First, compile the contracts on the local network.

npx hardhat compile

It's necessary to use only two ABI files: artifacts/contracts/EsolidarSweepstake.sol/EsolidarSweepstake.json and artifacts/contracts/ERC721EsolidarSweepstake.sol/ERC721EsolidarSweepstake.json. Edit these two files and copy only the ABI object:

  "abi": [
    {
      "inputs": [],
      "stateMutability": "nonpayable",
      "type": "constructor"
    },
    etc...
  ]

Paste on the Next.js ABI file inside src/ABI folder.

Tests

To run the test script:

npx hardhat test test/esolidar-sweepstake.test.js
