# DeFi Labelling in Argos: How We Classify Every Transaction on Ethereum

Argos has developed a system to label every transaction on Ethereum, helping users understand the purpose of DeFi activities. The system classifies transactions such as arbitrage, swaps, and other common DeFi actions, and is detailed in a post on their official blog.

Argos, a blockchain analytics platform, has published a blog post detailing how they classify every transaction on the Ethereum network. The system labels transactions based on their purpose, such as arbitrage, swaps, or liquidations, making it easier for users to understand the underlying activities in DeFi. The post specifically focuses on how Argos handles arbitrage detection and the methodology behind their labelling approach.

The system uses advanced algorithms to identify patterns and behaviors in transactions, providing clear labels for each action. For example, it can distinguish between a simple token swap and a complex arbitrage strategy, offering transparency and clarity to both novice and experienced users. The article on Hacker News points to the original Argos blog post as the source of this information.

While the draft describes plans to expand to other networks, the source article only details the current Ethereum-focused system. The key takeaway is that Argos is adding descriptive labels to on-chain transactions to help users better interpret DeFi activities, with a particular emphasis on detecting arbitrage trades.
