The ethereum London Upgrade: What You Need to Know

The Ethereum London upgrade has been eagerly anticipated by the crypto community. This major network update is set to improve the functionality, efficiency, and overall user experience of the Ethereum blockchain. One particular aspect of interest is its impact on decentralized finance (defi). In this article, we will delve into the details of the Ethereum London upgrade, including its release date, key features, and its significance for the DeFi ecosystem.

Release Date of the Ethereum London Upgrade

The Ethereum London upgrade is scheduled to take place on August 4th, 2021. This highly anticipated event will mark a significant milestone in the evolution of the Ethereum blockchain. The upgrade will be implemented through a process known as a hard fork, which ensures that all Ethereum network participants upgrade to the new version of the software.

Key Features of the Ethereum London Upgrade

The Ethereum London upgrade introduces several important improvements to the Ethereum network. One of the most notable features is the implementation of the EIP-1559 proposal, which aims to address the network’s long-standing issue of high transaction fees. With EIP-1559, transaction fees will become more predictable and efficient, benefiting both users and developers.

Another key feature is the integration of five additional Ethereum Improvement Proposals (EIPs). These EIPs focus on enhancing the overall functionality and security of the Ethereum network. Some of the EIPs included in the Ethereum London upgrade are EIP-3198 (BASEFEE opcode), EIP-3529 (Reduces gas refunds), and EIP-3541 (Reject new contracts starting with the 0xEF byte).

The Impact of the Ethereum London Upgrade on Decentralized Finance

Decentralized finance, or DeFi, has played a significant role in the growth and adoption of the Ethereum blockchain. The Ethereum London upgrade is expected to have a profound impact on the DeFi ecosystem. With the implementation of EIP-1559, transaction fees are expected to become more manageable, making DeFi applications more accessible to a wider audience.

Furthermore, the additional EIPs included in the upgrade aim to enhance the security and efficiency of smart contracts, which are the building blocks of many DeFi protocols. This increased security and efficiency will foster the development of innovative DeFi applications and improve the overall user experience.


The Ethereum London upgrade represents a major milestone in the advancement of the Ethereum blockchain. With its scheduled release date on August 4th, 2021, the upgrade will introduce key features such as the implementation of the EIP-1559 proposal and the integration of additional EIPs. Its impact on decentralized finance is expected to be significant, improving accessibility, security, and efficiency within the DeFi ecosystem. As the Ethereum network continues to evolve, it remains at the forefront of innovation in the blockchain industry.
