Class UiIncentiveDataProviderClient

The UiIncentiveDataProviderClient class provides methods to interact with the UI Incentive Data Provider contract on the Aptos blockchain. It extends the AptosContractWrapperBaseClass and includes functionalities for retrieving incentive data for reserves and users, including reward information, emission rates, and user-specific incentive data within the AAVE protocol.

Remarks

This client is designed to work with the UI Incentive Data Provider contract and provides a high-level API for accessing incentive-related data in a format suitable for UI applications. 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

// Using buildWithDefaultSigner
const provider = new AptosProvider();
const client = UiIncentiveDataProviderClient.buildWithDefaultSigner(provider);

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

// Get full reserves incentive data
const { aggregatedReservesIncentivesData, userReserveIncentiveData } =
  await client.getFullReservesIncentiveData();

Param: provider

The AptosProvider instance used to interact with the Aptos blockchain.

Param: signer

Optional Ed25519Account signer for transaction signing.

      The identifier of the function to call.

    • funcArgs: (EntryFunctionArgumentTypes | SimpleEntryFunctionArgumentTypes)[]

      The arguments to pass to the function.

    • typeArgs: string[] = []

      Optional generic type arguments for the function (e.g. ["0x1::aptos_coin::AptosCoin"]).

    Returns Promise<T>

    • A promise that resolves to the result of the view method call.

fundAccount

  • fundAccount(
        account: AccountAddress,
        amount: bigint,
    ): Promise<UserTransactionResponse>

    Funds an account with a specified amount.

    Parameters

      The address of the account to be funded.

    • amount: bigint

      The amount to fund the account with, in bigint.

    Returns Promise<UserTransactionResponse>

    A promise that resolves to a UserTransactionResponse.

getAccounAptBalance

  • getAccounAptBalance(
        account: Ed25519Account,
        accountAddress: AccountAddress,
        versionToWaitFor?: bigint,
    ): Promise<bigint>

    Retrieves the Aptos balance of a specified account.

    Parameters

    • account: Ed25519Account

      The Ed25519 account object.

    • OptionalversionToWaitFor: bigint

      (Optional) The specific version to wait for before retrieving the balance.

    Returns Promise<bigint>

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

getEventsFromAccount

  • getEventsFromAccount(
        account: AccountAddress,
        limit: number,
    ): Promise<
        {
            account_address: string;
            creation_number: any;
            data: any;
            event_index: any;
            indexed_type: string;
            sequence_number: any;

getTxEvents

  • getTxEvents(txHash: HexInput): Promise<{ data: unknown }[]>

    Retrieves the events associated with a given transaction hash.

    Parameters

    • txHash: HexInput

      The hash of the transaction to retrieve events for.
