Envio Developer Update March 2026
March saw continued progress across HyperIndex, tooling, and the wider Envio ecosystem. We shipped multiple alpha releases focused on improving scale, flexibility, testing, and observability, alongside new workflows that make it easier to go from idea to production-ready indexers. This includes the latest v3.0.0-alpha.20 release, which introduces improved multiple data-sources support and primary source recovery logic. This month we also rebranded our Hosted Service to Envio Cloud. Alongside this, we introduced updates across subgraph hosting, agentic indexing workflows, and new ways to explore and interact with prediction market data. Across the ecosystem, we saw strong developer contributions, new projects being built with Envio, and continued momentum leading into upcoming events.
Let's dive in!
💻 Alpha Releases: Alpha.15 -> Alpha.20
Loads of exciting progress landed across the latest alpha releases this month. This stretch focused on improving scale, flexibility, testing, and the overall developer experience across HyperIndex, with a mix of new features, internal improvements, and important updates to observability.
Alpha.20
🔁 Improved Multiple Data-Sources Support
With this change, we are introducing primary source recovery logic: after switching to a fallback source, HyperIndex attempts to recover to the primary source 60 seconds later. Previously, it would stay at the fallback source until the fallback source was down or the indexer was restarted.
Additionally, we improved the logic for choosing which data source to use next, enabling much better indexing resilience and reducing vendor lock-in to a single source, as well as stricter enforcement of the source usage configured for live mode.
Alpha.18
⚡ Support indexers with 2.1B+ events per chain
Scale indexers approaching int32 limits. Now you can build even larger, more performant indexers with HyperIndex.
🚨 Breaking: Official /metrics endpoint
Existing Prometheus metrics just got a major upgrade.
We cleaned up metric names and measured data, switched time units to seconds instead of milliseconds, and started following Prometheus naming conventions more closely.
We also added metrics for data points previously covered by the --bench feature.
Starting with v3.0.0, Prometheus metrics are no longer experimental. The /metrics endpoint now follows semver and will be documented.
Alpha.15
🔍 New getWhere operators: _gte, _lte, _in
Three new filter operators have been added for getWhere queries, following Hasura-style conventions:
context.Entity.getWhere({ amount: { _gte: 100n } })
context.Entity.getWhere({ amount: { _lte: 500n } })
context.Entity.getWhere({ status: { _in: ["active", "pending"] } })
👨🚒 Support double handler registration
Allows double handler registration for the same event with similar filters:
import { ERC20 } from "generated";
ERC20.Transfer.handler(async ({ event, context }) => {
// Your logic here
});
ERC20.Transfer.handler(async ({ event, context }) => {
// And here
});
🤖 Other improvements
We consistently improve HyperIndex to make it easier to contribute to for both humans and AI. Recent work includes:
- Restructuring HyperIndex into a pnpm workspace
- Moving tests from mocha/chai to vitest
- Reworking the CI pipeline to run faster and reuse the production artifact for both testing and publishing
- Developing a highly customisable internal testing framework so AI can create reproduction tests for tricky edge cases

Hosted Service is now Envio Cloud
We've renamed the Hosted Service to Envio Cloud. Same product, same infrastructure, no changes required on your end. For those new to it, Envio Cloud is a fully managed hosting solution for your indexers, taking care of all infrastructure, scaling, and monitoring so you can focus on building. Plans range from free dev environments through to enterprise-grade dedicated hosting, with static production endpoints, built-in alerts, and production-ready infrastructure across all tiers.

Agentic blockchain indexing with Envio
We explored what it looks like to go from prompt to production-ready indexers using Envio.
This walkthrough shows how to scaffold an indexer for any EVM-compatible chain, push it to GitHub, and deploy it to Envio's Cloud (previously Hosted Service) without manually touching a config file.
As an example, 400,000+ wstETH events were indexed on Monad in ~20 seconds.
Use the following command to scaffold your indexer:
pnpx envio@3.0.0-alpha.18 init template -t erc20 -l typescript -d ./my-indexer --api-token ""
Learn more in our blog and test it yourself here: https://docs.envio.dev/blog/agentic-blockchain-indexing-envio-hyperindex
Host your subgraphs on Envio
Deploy and host your subgraphs with HyperIndex, with a fully subgraph-compatible GraphQL endpoint and no client changes required.
Migrate your existing subgraphs and keep the same API, with faster sync, quicker backfills, and deployments live in less than a day.
The process is handled end-to-end, converting your subgraph to HyperIndex and getting it up and running without needing to manage infrastructure.

🧑💻 Featured Developer: Praveen Matheesha
This month's featured developer is Praveen Matheesha, a developer focused on building advanced onchain analytics infrastructure. He is currently working on @paralensdotai, a next-generation blockchain analytics engine designed to extract economic behavior and strategy-level insights from raw blockchain transactions. His focus is on turning complex onchain data into meaningful signals for traders, researchers, and analysts, with a particular interest in transaction-level intelligence, MEV analysis, and understanding the economic intent behind smart contract interactions.
What Praveen had to say about Envio:
"Before discovering Envio, I was building my own EVM indexer from scratch in Rust. I implemented support for chain reorg handling, historical backfilling, batched RPC ingestion, and WebSocket streams for real-time updates. While it worked, a significant amount of time went into building and maintaining the infrastructure layer itself. When I discovered Envio and HyperSync, it immediately stood out as a much more efficient approach. It solves many of the challenges around reliable, high-performance blockchain data access that developers often end up rebuilding from scratch. If I had found it earlier, I likely could have saved weeks of work and focused more on the actual analytics and business logic rather than the ingestion pipeline. I also wrote a detailed article about building a production-ready EVM indexer in Rust, where I mentioned Envio as a great option for developers who want to avoid spending weeks building indexing infrastructure themselves. Overall, HyperSync makes it significantly easier to work with large volumes of on-chain data and allows developers to focus on building insights and applications instead of reinventing core data infrastructure."
Well done, Praveen. Be sure to follow the team on X and check out their GitHub to stay up to date with their latest developments.
