Circles Data Methods

Circles Data class provides various methods to query and interact with Circles' data, such as balances, transaction history, trust relations, group memberships, and avatar information. It is built around the Circles RPC to facilitate communication with the blockchain and retrieve relevant data. The CirclesData class exposes methods for both CRCv1 and CRCv2 tokens, trust events, and group information, as well as subscriptions to events.

1. getTotalBalance

getTotalBalance(avatar: string, asTimeCircles?: boolean): Promise<string>

Parameters:

  • avatar: The address to get the CRC balance for.

  • asTimeCircles (optional): Return the balance as TimeCircles or not (default is true).

Returns: A Promise<string> representing the total balance.

Usage Example:

const balance = await circlesData.getTotalBalance("0xAvatarAddress");

2. getTotalBalanceV2

Gets the total CRC V2 balance of an address.

getTotalBalanceV2(avatar: string, asTimeCircles?: boolean): Promise<string>

Parameters:

  • avatar: The address to get the CRC balance for.

  • asTimeCircles (optional): Return the balance as TimeCircles or not (default is true).

Returns: A Promise<string> representing the total balance.

Usage Example:

const balanceV2 = await circlesData.getTotalBalanceV2("0xAvatarAddress");

3. getTokenBalances

Gets the detailed token balances of an address.

getTokenBalances(avatar: string): Promise<TokenBalanceRow[]>

Parameters:

  • avatar: The address to get the token balances for.

Returns: A Promise<TokenBalanceRow[]> containing the token balances.

const balances = await circlesData.getTokenBalances("0xAvatarAddress");

4. getTransactionHistory

Gets the transaction history of an address (incoming/outgoing transactions and CRC minting).

getTransactionHistory(avatar: string, pageSize: number): CirclesQuery<TransactionHistoryRow>

Parameters:

  • avatar: The address to get the transaction history for.

  • pageSize: The maximum number of transactions per page.
