    Class CoinMigratorClient

    The CoinMigratorClient class provides methods to interact with the Coin Migrator contract on the Aptos blockchain. It extends the AptosContractWrapperBaseClass and includes functionalities to convert coins to FA and vice versa, as well as retrieve the FA address.

    This client is designed to work with the Coin Migrator contract and provides a high-level API for coin migration 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
    // Using buildWithDefaultSigner
    const provider = new AptosProvider();
    const client = CoinMigratorClient.buildWithDefaultSigner(provider);

    // Using constructor directly
    const provider = new AptosProvider();
    const signer = provider.getPoolProfileAccount();
    const client = new CoinMigratorClient(provider, signer);

    // Convert coins to FA
    const tx = await client.coinToFa(1000n, "0x1::aptos_coin::AptosCoin");

    The AptosProvider instance used to interact with the Aptos blockchain.

    Optional Ed25519Account signer for transaction signing.

      Returns Promise<bigint>

      A promise that resolves to the balance of the account in bigint.

    • Retrieves the FA (Fungible Address) associated with the Aptos Coin migrator contract.

      This method calls the GetFaAddrFuncAddr view method on the coin migrator contract and maps the response to an AccountAddress object.

      Returns Promise<AccountAddress>

      A promise that resolves to the FA address as an AccountAddress object.

    • Retrieves events associated with a specific account.

      Parameters
