gm web3 devs!
What a month May was! There’s always movement at an incredible pace in The Graph ecosystem, and we appreciate you taking a few minutes to read this newsletter for a summary of what some of the best and brightest are doing for our shared decentralized future.
We hope that by working on this summary every month, we make it a little bit easier to stay informed when building on The Graph.
Cheers everyone! 🙌
Before we go through these sections, please give us your feedback with this easy Developer Survey:

Substream-Powered Subgraphs News Roundup
Core dev has been working hard building for the past few years, aiming to make indexing blockchain data upwards of 100x faster. Substreams are gradually being brought to the mainstream, and we are seeing more and more substream-powered subgraphs at hackathons and in production!
Check out May’s substream highlights:
Substreams at EthGlobal Lisbon
from core dev shared her at EthGlobal Lisbon that detailed the power of substreams as well as diving into some of their components.
In the presentation, she provides a high-level overview of substreams as well as goes into the fundamentals of how to build a substream.
Substream-Powered Uniswap Subgraph Sync in 20 Hours
developed by StreamingFast and on The Graph Network on May 19th formerly took 2 months to index without substreams.
Now that the subgraph is powered by substream technology, syncing only took 20 hours!
That’s a 72x speed increase!
This is a landmark in infrastructure architecture for all of web3 and we applaud for this massive achievement.
Start Building a Substreams-Powered Subgraph
Buidler of and built a very simple that “only” tracks contract creations, something that was not possible with subgraphs before.
This serves as a great working example of a substream fueling a subgraph in action, as substreams are effectively a new data source for subgraphs. Not only can subgraphs listen to events, they can now gather much more granular data such as contract creations through the power of substreams.

“The Graph Unlocks a New Web3 Use Case: Organizing Off-chain Data” by
With the introduction of , the door is now open for parallel indexing off-chain data through subgraphs. Edge & Node’s own goes through a few different use-cases of how this could be implemented in your dapps in , such as hosting blog data, prioritizing content by having a custom feed based on publicly expressed behaviors, as well as real-time monitoring from an oracle.
It’s important to note how this itself is an important paradigm shift for The Graph ecosystem as a whole. On-chain data is the primary data source for The Graph, but now with off-chain data as another primary component of The Graph’s data pipeline, subgraphs are becoming even more powerful dapp data portals 🎇
“Two Simple Subgraph Performance Improvements” by David Lutterkort
Edge & Node’s provided on easy ways to optimize a subgraph such as using Immutable Entities as well as Bytes as IDs. These two features are easy to implement in subgraphs and improve subgraph performance substantially.
How substantially you might ask?
When both features were used, block processing was 28% faster and there was a 48% decrease in storage requirements, meaning faster queries and improved storage capacity! 🔥
Let’s go through an example of an Immutable Entity as well as an example of using Bytes as IDs:
Immutable Entity
Converting a Transfer entity to an Immutable Entity is advisable when there's no plan to update the entity's shape in the future. For example, this immutable conversion would be appropriate in the case where an entity directly represents on-chain activity without additional logic being performed in mappings.ts.
Once converted to immutable (as seen by adding (immutable: true) to the Transfer entity below), the entity is now unable to be altered in future subgraph updates and allows graph-node to be much more performant!

Bytes as ID
To share an example of Bytes as ID, let's look at the above example and convert the id type from ID to Bytes.
.png)
See David Lutterkort’s for various strategies to transform data extracted from the blockchain into Bytes in your mappings.ts. By using the low-level type of Bytes for your IDs, graph-node can once again be much more performant!
These features are available in graph-node versions 0.26.0 and beyond, and subgraph authors need to use graph-cli version 0.28 or higher, and graph-ts version 0.26 or higher.

The Graph at EthGlobal Lisbon Review
EthGlobal Lisbon was a huge success! From presenting on substreams to from Edge & Node on an account abstraction panel as well as a wonderful hackathon, it was truly a blast!
There was a significant increase in the use of The Graph during the hackathon - we had 33 submissions using The Graph! We just want to congratulate the winners and participants of the hackathon and wish you a happy building experience in all coming events!
Best New Subgraph:
Best Use of Existing Subgraphs:

TreasuryDAO
The first prize hackathon submission for Best New Subgraph was , a groundbreaking toolkit for on-chain treasury management of decentralized autonomous organizations (DAOs). Designed to address the limitations of traditional multi-sig wallets, Treasury DAO enables any DAO deployed on Polygon, Optimism, or Arbitrum to interact with DeFi protocols through governance proposal payloads. The subgraphs they designed indexed factory smart contracts, providing an elegant way of gathering data we loved to see!
We were inspired by TreasuryDAO’s project as it aims to improve the management of DAO coordination, something we appreciate!
Pinky Protocol
The first prize hackathon submission for Best Use of Existing Subgraphs was , a protocol that aims to revolutionize NFT lending and borrowing with a collateral-free approach. By integrating with the borrower's smart contract wallet, Pinky ensures secure loans without the risk of liquidation. Lenders can list their NFTs on the Pinky platform, specifying price and duration, while borrowers can select from available NFTs and pay upfront interest. The borrower gains full control over the NFT during the borrowing period, while the plugin integrated into their wallet prevents transfers.
The project leveraged The Graph to monitor for borrowing events through smart contracts to update their front-end, which was a clean and effective use-case for The Graph we enjoyed!
Announcing The Graph Builders Blog
The vision of The Graph is to be a powerful permissionless indexing protocol that is supportive, collaborative, and self-sustaining.
We are very excited to announce The Graph Builders Blog as a new valuable piece of this collaborative vision.
We know that building decentralized applications is not always an easy task, and sometimes it can be challenging to find the right resources and information. That's why we want to create a space where builders can come together, learn from each other, and share their knowledge with the wider community.
