Returns a Promise that resolves to the initialized IBiconomySmartAccount. | | initializeAccountAtIndex | accountIndex: number | Initializes the smart account at the specified accountIndex. | | getExecuteCallData | to: string, value: BigNumberish, data: BytesLike | Returns the call data for executing a single transaction to the specified address (to) with the given value and data. | | getExecuteBatchCallData | to: Array string , value: Array BigNumberish, data: Array BytesLike | Returns the call data for executing a batch of transactions to multiple addresses (to) with the corresponding value and data arrays. | | buildUserOp | transactions: Transaction[], overrides?: Overrides | Builds a UserOperation object from the provided array of Transactions. It also accepts optional overrides for specifying gas limits and gas prices. Returns a Promise that resolves to the partial UserOperation. | | getAllTokenBalances | balancesDto: BalancesDto | Retrieves the balances of multiple tokens for the smart account based on the provided balancesDto. Returns a Promise that resolves to the BalancesResponse containing the token balances. | | getTotalBalanceInUsd | balancesDto: BalancesDto | Retrieves the total balance of all tokens in USD for the smart account based on the provided balancesDto. Returns a Promise that resolves to the UsdBalanceResponse. | | getSmartAccountsByOwner | smartAccountByOwnerDto: SmartAccountByOwnerDto | Retrieves all smart accounts owned by the specified address based on the provided smartAccountByOwnerDto. Returns a Promise that resolves to the SmartAccountsResponse containing the array of smart account addresses. | | getTransactionsByAddress | chainId: number, address: string | Retrieves the transactions associated with the specified address on the given chainId. Returns a Promise that resolves to an array of SCWTransactionResponse objects containing information about the transactions. | | getTransactionByHash | txHash: string | Retrieves the transaction details for the specified transaction hash (txHash). Returns a Promise that resolves to a SCWTransactionResponse object containing information about the transaction. | | getAllSupportedChains | N/A | Retrieves information about all supported chains. Returns a Promise that resolves to the SupportedChainsResponse containing the list of supported chains. |

ISmartAccount Interface

The ISmartAccount interface provides essential methods for interacting with a Biconomy Smart Account.

Method	Parameters	Description
getSmartAccountAddress	accountIndex: number	Retrieves the address of the smart account at the specified accountIndex. Returns a Promise that resolves to the smart account address.
signUserOp	userOperation: UserOperation	Signs the given UserOperation with the necessary cryptographic signature. Returns a Promise that resolves to the signed UserOperation.
sendUserOp	userOperation: UserOperation	Sends the provided UserOperation to the Biconomy network for execution. Returns a Promise that resolves to a UserOpResponse containing the response from the network.
sendSignedUserOp	userOperation: UserOperation	Sends the pre-signed UserOperation to the Biconomy network for execution. Returns a Promise that resolves to a UserOpResponse containing the response from the network.
