@biconomy-devx/account-abstraction v1.0.17
SDK to create and send UserOperation
This package provides 2 APIs for using UserOperations:
- Low-level "walletAPI"
- High-level Provider
LowLevel API:
BaseWalletAPI
An abstract base-class to create UserOperation for a contract wallet.
SmartAccountAPI
An implementation of the BaseWalletAPi, for the Biconomy SmartAccount
owner = provider.getSigner()
const smartWalletAPI = new SmartAccountAPI(
provider,
entryPoint, // instance of the entry point contract
config, // instance of ClientConfig
walletAddress, // counter factual wallet address (smartAccount.address)
originalSigner, // owner
fallbackHandlerAddress,
factoryAddress, // wallet factory address
0 // index
)
const op = await smartWalletAPI.createSignedUserOp({
target: recipient.address,
data: recipient.interface.encodeFunctionData('something', ['hello'])
})
High-Level Provider API
A simplified mode that doesn't require a different wallet extension. Instead, the current provider's account is used as wallet owner by calling its "Sign Message" operation.
This can only work for wallets that use an EIP-191 ("Ethereum Signed Message") signatures (like our sample SimpleWallet) Also, the UX is not great (the user is asked to sign a hash, and even the wallet address is not mentioned, only the signer)
