Developing a new Substreams requires a deep understanding of general blockchain technology, being familiar with the specific chain you are developing on, and the ability to write Rust code. But don’t worry, you don’t have to be an expert in any of those fields! Thanks to the composability of Substreams…

Today, we are thrilled to ship the first milestone of Substreams.dev with the registry. This open community repository of available Substreams is your go-to place for discovering, publishing, and managing modules. You can start exploring the Substreams modules built by The Graph ecosystem, check their definitions, inputs and outputs, and…

The Graph is a prime example of what can be achieved when you bring together a decentralized group of builders, all working towards a common goal. The core protocol itself is led by several core development teams: Edge & Node, StreamingFast, Semiotic, The Guild, GraphOps, and Pinax. Beyond those teams…

Ed from StreamingFast gives a quick tutorial on how to use Substreams to easily sink events from an Ethereum smart contract to an SQL database.

Here is a quick example to explore what Substreams are, what the role of a Substreams provider is, and how simple it can be to write your first Substreams package. Transcript: Extracting data from blockchain is hard, but extracting data from blockchain in a fast and reliable way is…

Substreams and Firehose enable a Shared Intelligence Layer. Fancy words, but what does it mean? Blockchains hold a lot of valuable, yet opaque data. By shifting the transformation of data lower down in the stack, and doing so in a shared and open fashion, Substreams unlocks rich and actionable…

The latest version of the Substreams GUI allows you to see insights on your Substreams execution and spot potential bottlenecks in your modules! One of the most powerful features of Substreams is that you can use the output of a Substreams module as an input for another Substreams module. This…

ERC-20 is the most popular token standard for EVM-compatible blockchains. ERC-20 tokens such as USDT, USDC, or BUSD are among the most used ERC-20 tokens, so the demand for retrieving, tracking and transforming these kinds of tokens efficiently has increased lately. Consider that you want to retrieve the current USDT…

StreamingFast is thrilled to announce the completion of the Substreams beta integration with Arbitrum One! Currently, we are working with Offchain Labs to have the integration merged upstream. Arbitrum has become one of the largest blockchains in the crypto ecosystem with an ever-growing ecosystem of builders and dapps. We’re excited…
