# burnFrom

The `burnFrom` function is an integral part of the StableCoin Contracts, enabling the burning of tokens from a specified user's account. This function is particularly useful in scenarios where tokens need to be removed from circulation in a controlled manner, often as part of staking, governance, or reward mechanisms. The operation is contingent upon having prior approval from the token owner, typically granted through the `approve` method.

## Method Signature

```typescript
async burnFrom(from: string, amount: string, signer: any): Promise<string>
```

## Parameters

* `from: string`: The Ethereum address from which the tokens will be burned. This can be a standard Ethereum address or an ENS name.
* `amount: string`: The quantity of tokens to burn, represented as a string.
* `signer: any`: An object representing the signer of the transaction, commonly sourced from a wallet interface like MetaMask or ethers.js.

## Function Logic

1. **Resolve ENS Name**: If the `from` address is an ENS name, it's resolved to its corresponding Ethereum address.
2. **Get Contract Instance**: Acquires a contract instance using the `signer` to interact with the blockchain.
3. **Burn Transaction**: Executes the `burnFrom` method on the contract with the resolved `from` address and the specified `amount`.
4. **Return Result**: Outputs the result of the burn transaction, typically a transaction hash, as a string.

## Example Usage

```typescript
const fromAddress = "holder.eth";
const amount = "200";
const signer = ethersProvider.getSigner();

stableCoinContract.burnFrom(fromAddress, amount, signer)
    .then(result => 
        // add your logic here 
    )
    .catch(error => 
        // add your logic here
    );
```

## Notes

* The `burnFrom` method requires careful handling due to its ability to remove tokens from another user's account.
* Proper formatting of the `amount` parameter is crucial to ensure successful and intended transaction execution.
