Cover Image 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.

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.19​

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.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

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.

Agentic blockchain indexing with Envio​

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 ""

Host your subgraphs on Envio​

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.

EthCC[9]: Sapphire Sponsor​

EthCC sponsorship

Envio is a Sapphire sponsor of EthCC[9], taking place at Palais des Festivals in Cannes from March 30 to April 2, 2026.

EthCC is an annual Ethereum community conference bringing together developers, researchers, and teams from across the ecosystem.

The team will be there across the week. Catch our talk on the Monroe stage and swing by our booth - let's chat about your data needs.

P.S. be sure to get your hands on one of our snazzy Envio caps and stickers.

Developer contributions: Uniswap CCA indexer​

Uniswap CCA indexer

Check out this Uniswap CCA indexer built with HyperIndex to index continuous clearing auction contracts across Ethereum, Base, Arbitrum, and Unichain. It tracks auctions, bids, ticks, steps, and checkpoints, using HyperSync for logs and selective RPC reads for derived onchain state.

Shoutout to @0xdivergence for sharing this and building with Envio.

Open Indexer Benchmark​

We believe tech should speak for itself.

That's why we started working on and maintaining the Open Indexer Benchmark (originally forked from Sentio).

An honest, objective benchmark for blockchain indexers.

We're reopening it to benchmark new use cases and warmly welcome all contributions:

Polymarket Whale Tracker TUI​

Polymarket Whale Tracker TUI

We put together a simple whale tracker using HyperSync to track Polymarket whale activity in real time. It follows large traders on Polymarket and surfaces what they're doing as it happens, making it easier to monitor higher-conviction activity without sifting through smaller trades.

Clean, fast, and easy to plug into your workflows.

Best blockchain indexers in 2026

We put together a benchmark-driven comparison of blockchain indexers, looking at how different solutions perform in practice. The guide focuses on how indexers handle real workloads, comparing performance, sync speeds, and overall reliability across different approaches.

It's a practical breakdown of the trade-offs between tools and what to consider when choosing an indexer for your use case.

🧑‍💻 Featured Developer: Praveen Matheesha​

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.
