Let’s get to know more about one of the developments iterated to enhance the usability of the Ethereum network and foster its wider adoption – Smart Accounts on Ethereum.

Ethereum (ETH) is a decentralized blockchain network that has undergone significant changes over time, such as the switch from proof of work to proof of stake consensus mechanism. The Ethereum 2.0 upgrade is a major milestone in this transition, but it is still a work in progress. Despite this, other important improvements have been made, with the potential to enhance the usability of the network and drive user adoption.

One such improvement is the deployment of smart accounts on the Ethereum blockchain. Smart accounts are a type of accounts that can be controlled by programmable smart contracts rather than private keys, allowing for more advanced functionality and automated management of assets and transactions. This can include multi-signature authorization, time-based unlocking, and threshold-based transaction limits, as well as the implementation of complex business logic and security measures.

Smart Accounts Defined

As said above, smart accounts are a type of account on the Ethereum blockchain that can be controlled by programmable smart contracts rather than private keys. This means that the functionality of the account can be customized and automated using code, rather than relying solely on manual intervention from the account holder.

Smart accounts offer a range of advanced features, such as multi-signature authorization, time-based unlocking, and threshold-based transaction limits. They also enable the implementation of more complex business logic and security measures, such as payment plans and revenue-sharing arrangements that can be enforced automatically without the need for third-party intermediaries.

Account Abstraction Explained

Account abstraction is an emerging standard in the Ethereum blockchain ecosystem that allows the transformation of a regular wallet into a smart contract account. It was previously known as ERC-4337, but the standard was not officially adopted. The feature has already been deployed on a smart contract, and it is expected to be supported by several Ethereum infrastructure providers in the future.

Account abstraction is a significant development that could greatly enhance the usability of wallets and improve the security of user accounts. By transforming a wallet into a smart contract account, the feature provides more advanced functionality, including multi-signature authorization and time-based unlocking, which can help prevent the loss of private keys and secure user accounts.

Another important aspect of account abstraction is its compatibility with other EVM-compatible blockchains, including Binance Smart Chain (BSC), Polygon (MATIC), and Avalanche (AVAX). This means that the feature can be used across multiple blockchain networks, enabling greater interoperability and flexibility for users.

While it was initially expected to take until 2024 for account abstraction to be deployed, the feature has already undergone a full security audit and is now available for use. It may take some more time for the feature to become widely adopted, but its potential impact on improving the security and usability of wallets makes it an exciting development for the Ethereum ecosystem.

Launch of Smart Accounts

Smart accounts were not launched as a single event, but rather as a gradual evolution of the capabilities of the Ethereum blockchain. As the Ethereum ecosystem has grown and matured, developers and businesses have increasingly turned to smart contracts to create more sophisticated and secure financial applications on the blockchain.

While smart accounts are not a distinct product or service that can be launched, several developments have contributed to their emergence as a powerful tool for creating more advanced financial applications on the Ethereum blockchain. These include the introduction of the ERC-20 standard for creating fungible tokens, the development of more advanced programming languages such as Solidity and Vyper for writing smart contracts, and the emergence of infrastructure providers and tooling to support the development of decentralized applications on the Ethereum network.

Moreover, the emergence of account abstraction that allows wallets to be transformed into smart contract accounts, has further expanded the capabilities of smart accounts and enhanced their usability and security. This development enables the implementation of more advanced functionality, such as multi-signature authorization and time-based unlocking, and allows for more complex business logic and security measures to be enforced automatically without the need for third-party intermediaries.

Externally Owned Accounts (EOAs)

The majority of accounts created on the Ethereum blockchain and other EVM networks are known as externally owned accounts or EOAs. EOAs use traditional key pairs, meaning they consist of a single private key that is used to sign messages and make transactions. However, this also means that if someone gains access to your private key, they have full control over your account and funds.

Popular wallets like Metamask and imToken, as well as hardware wallets such as Ledger Nano and Trezor, are all examples of EOAs. Despite their popularity, EOAs are susceptible to security risks since the private key is a single point of failure. If your private key is lost or stolen, you could lose access to your funds.

To address this issue, account abstraction was developed as a new standard for Ethereum, with the goal of allowing wallets to become smart contract accounts. Smart accounts leverage the added security and functionality of smart contracts to enable features like multi-signature authorization and time-based unlocking. By doing so, smart accounts aim to provide users with a more secure and flexible option for managing their funds on the Ethereum network.

Contract Accounts (CA)

A contract account (CA) is a unique type of account on the Ethereum blockchain that is owned and managed by a smart contract, rather than an individual or entity. This means that the smart contract code determines how the Ether within the account is managed and utilized.

Notably, contract accounts provide a powerful tool for developers and businesses to create more sophisticated and automated financial applications on the Ethereum blockchain. By allowing for more complex functionality and automation, contract accounts can enhance the efficiency and security of financial transactions and other applications built on the Ethereum platform.

However, it’s important to note that contract accounts still require an externally owned account (EOA) to deploy and execute their functions. The EOA is responsible for initiating transactions and interacting with the smart contract code, which then determines how the Ether within the CA is utilized.

EOAs vs Smart Accounts

Externally owned accounts and smart accounts are both types of accounts in the Ethereum blockchain, but they have different characteristics and purposes.

EOAs are the most basic type of Ethereum account. They are controlled by private keys, and transactions can be initiated only by the account owner. EOAs are used mainly for holding ether and sending transactions to other accounts, including smart contracts.

Smart accounts, on the other hand, are more complex and have more functionality than EOAs. Smart accounts are smart contracts that have been deployed to the blockchain and have their own Ethereum address.

Smart contracts are self-executing programs that can be programmed to perform specific actions when certain conditions are met. Smart accounts can interact with other smart contracts and can also execute code automatically based on predefined rules and conditions.

The key difference between EOAs and smart accounts is that smart accounts are programmable and can execute code, while EOAs are simply accounts that hold ether and can send transactions. Smart accounts can be used for a variety of purposes, including decentralized finance (DeFi) applications, voting systems, and supply chain management, among others.

In some cases, smart contracts may be owned by EOAs. For example, an individual may deploy a smart contract to the Ethereum network and own it through their EOA. In this case, the EOA would control the smart contract and be able to perform actions such as updating its code or interacting with other smart contracts.

Benefits of Using Smart Accounts

The use of smart accounts on the Ethereum network provides users with the following benefits.

  • Security. Smart accounts are built on the Ethereum blockchain, which uses cryptographic techniques to secure the network. This makes smart accounts highly secure and resistant to hacking and fraud.
  • Transparency. Smart contracts are transparent, meaning that the code is open and visible to everyone on the network. This makes it easy to audit the code and verify that it is working as intended.
  • Automation. Smart accounts are self-executing programs that can automate a wide range of tasks, making them highly efficient and reducing the need for manual intervention.
  • Cost-effectiveness. Smart accounts can automate tasks and reduce the need for intermediaries, making them highly cost-effective. This is especially true for tasks that involve multiple parties, such as supply chain management and decentralized finance.

Final Thoughts

Smart accounts on Ethereum have revolutionized the way agreements and transactions are conducted, enabling automated and trustless execution of contracts without the need for intermediaries. Smart contracts can be used for a wide range of applications, including financial instruments, insurance policies, supply chain management, and more.

While smart accounts on Ethereum offer a wide range of benefits, they are still a relatively new technology and may present some challenges, including the need for careful and secure programming to prevent vulnerabilities and the possibility of unforeseen consequences due to complex interactions between multiple smart contracts.
