getBalance

The getBalance function in StableCoin Contracts is designed to retrieve the balance of a specific Ethereum address in terms of the stablecoin tokens. This function is crucial for users and applications to check token balances, facilitating various transactions and operational decisions.

Method Signature

async getBalance(userAddress: string): Promise<string>

Parameters

• userAddress: string: The Ethereum address whose token balance is to be retrieved. This can be a standard Ethereum address or an ENS name.

Function Logic

1. Resolve ENS Name: If the userAddress is an ENS name, it is resolved to the corresponding Ethereum address.
2. Get Contract Instance: Obtains an instance of the stablecoin contract to interact with the blockchain.
3. Query Balance: Executes the balanceOf method on the contract with the user's address.
4. Return Result: The balance, typically a large number, is returned in a string format.

Example Usage

const userAddress = "user.eth";

stableCoinContract.getBalance(userAddress)
    .then(balance => 
        // add your logic here 
    )
    .catch(error => 
        // add your logic here
    );

Notes

• The getBalance function is a fundamental tool for token management and auditing in the context of ERC20 tokens.
• Accuracy in resolving ENS names to Ethereum addresses is vital for obtaining correct balance information.
