Introduction

The accounts package provides abstractions that wrap operations that interact with an account. An account typically contains a private key, allowing it to sign various types of payloads. There are the following interfaces that provide account operations for different purposes:

• Signer: Provides support for signing EIP-712 transactions as well as other types of transactions supported by types.Signer.
• AdapterL1: Associated with an account and provides common operations on the L1 network for the associated account.
• AdapterL2: Associated with an account and provides common operations on the L2 network for the associated account.
• Deployer: Associated with an account and provides deployment of smart contracts and smart accounts on the L2 network for the associated account.
• Adapter: Consists of AdapterL1, AdapterL2, and Deployer interfaces.

There are the following objects that provide account operations:

BaseSigner

Implements the Signer interface. The BaseSigner is responsible for signing various types of transactions, including EIP-712 transactions. It abstracts the complexities involved in signing transactions, making it easier for developers to handle secure and authenticated interactions with the blockchain.

WalletL1

Implements the AdapterL1 interface. WalletL1 is designed to manage and perform common operations on the Layer 1 (L1) network. This includes sending transactions, checking balances, and interacting with smart contracts deployed on the Ethereum mainnet.

WalletL2

Implements the AdapterL2 interface. WalletL2 facilitates operations on the Layer 2 (L2) network, specifically tailored for ZKsync Era. It handles transactions that benefit from the scalability and low fees of L2 solutions, providing a seamless way to interact with the L2 environment.

BaseDeployer

Implements the Deployer interface. The BaseDeployer provides functionalities for deploying smart contracts and smart accounts on the L2 network. It simplifies the deployment process, ensuring that developers can easily and efficiently deploy their applications on ZKsync Era.

Wallet

Implements the Adapter interface. The Wallet object combines the functionalities of AdapterL1, AdapterL2, and Deployer, offering a comprehensive tool for managing accounts and performing operations across both L1 and L2 networks. It is the recommended object for most use cases as it provides all necessary operations in one place.

SmartAccount

Provides enhanced support for account abstraction. The SmartAccount is designed to offer advanced account management capabilities, supporting complex account structures and operations.

NewECDSASmartAccount

Uses a single ECDSA key for signing payloads. This factory method creates a SmartAccount that leverages a single ECDSA key, ensuring simple yet secure transaction signing.

NewMultisigECDSASmartAccount

Uses multiple ECDSA keys for signing payloads. This method creates a SmartAccount that supports multisig functionality, enhancing security by requiring multiple signatures for transaction approval.
