CheckDot Token Smart Contract

Information

Here's the token details.

• Name: CheckDot
• Symbol: CDT
• Decimals: 6
• Total Supply: 10,000,000

Installation

Install node_modules for AS and Massa network.

npm install

Build

By default this will build all files in assembly/contracts directory.

npm run build

Deploy

Prerequisites :

• You must add a .env file at the root of the repository with the following keys set to valid values :
  • WALLET_SECRET_KEY="wallet_secret_key"
  • JSON_RPC_URL_PUBLIC
    • BuildNet: https://buildnet.massa.net/api/v2
    • TestNet: https://test.massa.net/api/v2:33035

These keys will be the ones used by the deployer script to interact with the blockchain.

The following command will build contracts in assembly/contracts directory and execute the deployment script src/deploy.ts. This script will deploy on the node specified in the .env file.

npm run deploy

You can modify src/deploy.ts to change the smart contract being deployed, and to pass arguments to the constructor function:

• line 31: specify what contract you want to deploy
• line 33: create the Args object to pass to the constructor of the contract you want to deploy

When the deployment operation is executed on-chain, the constructor function of the smart contract being deployed will be called with the arguments provided in the deployment script.

The deployment script uses massa-sc-deployer library to deploy smart contracts.

You can edit this script and use massa-web3 library to create advanced deployment procedure.

Format code

npm run fmt

Call Transaction (JS)

Example to burn CDT tokens

await client.smartContracts().callSmartContract({
    targetAddress: CONTRACT_ADDRESS,
    functionName: "burn",
    parameter: new Args().addU64(BigInt(1000000)).serialize(),
    maxGas: MAX_GAS,
    coins: BigInt(1),
    fee: BigInt(0),
});

Call View Function (JS)

Example to get total supply

await client.smartContracts().readSmartContract({
    maxGas: MAX_GAS,
    targetAddress: CONTRACT_ADDRESS,
    targetFunction: "totalSupply",
    parameter: new Args().serialize(),
})
