Blockchain data is public. Accessing and making sense of the data is hard though. Dozens of you, the builders shaping the future of the internet, told us about the vast amount of time spent going through fragmented tools, finding the right information you are looking for, and ensuring decisions are…

Traces provide a very crucial and interesting aspect of observability, which is context. Each pillar of observability fulfils a unique purpose, while logs help to uncover individual system errors and metrics show quantifiable anomalies over time, traces help to view and understand the entire lifecycle of a request or action…

Today’s blog article of our series “observability in web3” is all about numbers, more specifically — metrics. Metrics are important for observing the overall health of a system. The beauty of metrics is the possibility of using them for mathematical modeling, visualizing them in dashboards, aggregating them over time, and…

Intro After learning how to read every block from EVM chains, you might want to persist that data in a database and start pulling insights out of it. …

There is no software engineer in this universe that has not used print(), printf(), or console.log() for quick debugging. Just take a second and think about the last time you did exactly the same. There is nothing wrong with that during development. However, once the code is live in production…

Using a JSON RPC interface to fetch blocks, transactions or events is a classic task to do when on-chain data is needed. In this article, we will go through two simple ways to detect newly mined blocks, fetch them, and dismantle the data inside. The pre-requisites for this article are…

The development of web3 is growing at rapid speed. While the number of decentralized applications reaching scale is increasing, the architecture of decentralized applications is getting more and more complex. To ensure the reliability of complex software running on a high scale observability practices are indispensable, and without them, teams…

During prototyping some hacks for Blocktorch I wanted to filter addresses of contracts to track their transactions, event logs, and block data. Since I’m using ethers.js to interact with the json RPC interface, I looked in the lib docs but couldn’t find anything. …
