Origin Contract Functions

Overview​

This section focuses on the core functions of origin chain contracts.

Constructor Function​

UniswapDemoToken.sol
contract UniswapDemoToken is ERC20 {
    constructor(string memory name, string memory symbol) ERC20(name, symbol) {
        _mint(tx.origin, 100 ether);
    }
}

Parameters​

  • name: A string representing the name of the token.

  • symbol: A string representing the symbol of the token.

Description​

The constructor function in the UniswapDemoToken.sol contract initializes a custom ERC-20 token. It extends the functionality of the ERC-20 token standard and is invoked during the deployment of the contract. Upon deployment, the constructor sets the name and symbol of the token using the provided parameters. Additionally, it mints an initial supply of 100 ether tokens to the address that deployed the contract (tx.origin). This initialization process prepares the token for use in decentralized applications (dApps), enabling it to be integrated into platforms like Uniswap or other decentralized exchanges.
