/**
 * The `VariableTokensClient` class provides methods to interact with variable tokens on the Aptos blockchain.
 * It extends the `AptosContractWrapperBaseClass` and includes functionalities for managing variable debt tokens,
 * retrieving token metadata, balances, and other related information within the AAVE protocol.
 *
 * @remarks
 * This client is designed to work with variable debt tokens and provides a high-level API for token operations.
 * The client can be instantiated in two ways:
 * 1. Using the constructor directly with a provider and optional signer
 * 2. Using the static buildWithDefaultSigner method which automatically configures the client with the provider's pool profile account
 *
 * @example
 * ```typescript
 * // Using buildWithDefaultSigner
 * const provider = new AptosProvider();
 * const client = VariableTokensClient.buildWithDefaultSigner(provider);
 *
 * // Using constructor directly
 * const provider = new AptosProvider();
 * const signer = provider.getPoolProfileAccount();
 * const client = new VariableTokensClient(provider, signer);
 *
 * // Get token metadata and balance
 * const metadataAddress = await client.getMetadataBySymbol("USDC");
 * const balance = await client.balanceOf(userAddress, metadataAddress);
 *
 * // Get scaled balance and total supply
 * const { scaledUserBalance, supply } = await client.getScaledUserBalanceAndSupply(
 *   userAddress,
 *   metadataAddress
 * );
 * ```
 *
 * @param provider - The AptosProvider instance used to interact with the Aptos blockchain.
 * @param signer - Optional Ed25519Account signer for transaction signing.
