# Envio

> Envio is a real-time multichain blockchain indexer. Index, query, and stream onchain data across any EVM chain, plus Solana and Fuel. Up to 2000x faster than traditional RPC, with historical backfill and live event processing in one pipeline.

## Core products

- [HyperIndex](https://docs.envio.dev/docs/HyperIndex/overview.md): full-featured multichain indexing framework that transforms on-chain events into structured, queryable databases. Historical backfill and live events in one pipeline, automatic reorg handling, factory contract support, and a production GraphQL API via Hasura.
- [HyperSync](https://docs.envio.dev/docs/HyperSync/overview.md): high-performance blockchain data engine that replaces traditional JSON-RPC, delivering up to 2,000x faster data access across 86+ EVM chains and Fuel. Flexible filtering and field selection, with SDKs in Python, Rust, Node.js, and Go.
- [HyperRPC](https://docs.envio.dev/docs/HyperRPC/overview-hyperrpc.md): read-only JSON-RPC endpoint powered by HyperSync, up to 5x faster than traditional nodes like geth, erigon, and reth. Drop-in replacement for existing RPC tooling, specialised for `eth_getLogs` and other data-heavy reads.
- [Envio Cloud](https://docs.envio.dev/docs/HyperIndex/hosted-service.md): fully managed hosting for HyperIndex indexers. Git-based deploys, zero-downtime rollbacks, built-in monitoring, production GraphQL endpoints, multichain support, and multi-channel alerts.

## Quick-start paths

- I want to index contract events with custom business logic: use HyperIndex. Quickstart: https://docs.envio.dev/docs/HyperIndex/contract-import.md
- I want raw blocks, logs, and transactions as fast as possible: use HyperSync. Quickstart: https://docs.envio.dev/docs/HyperSync/hypersync-quickstart.md
- I want a drop-in JSON-RPC for data-heavy reads: use HyperRPC. See https://docs.envio.dev/docs/HyperRPC/overview-hyperrpc.md
- I want to migrate from The Graph or Alchemy: see https://docs.envio.dev/docs/HyperIndex/migration-guide.md
- I want a managed, hosted deployment: use Envio Cloud. See https://docs.envio.dev/docs/HyperIndex/hosted-service.md
- I want to build an indexer with an AI coding assistant (Claude Code, Cursor, etc.): see https://docs.envio.dev/docs/HyperIndex/quickstart-with-ai.md

## HyperIndex

HyperIndex lets developers:

- Write handlers in TypeScript, JavaScript, or ReScript.
- Auto-generate indexers directly from a smart contract address or ABI.
- Process historical backfills and live events in one pipeline at over 10,000 events per second.
- Handle chain reorganizations automatically without sacrificing latency.
- Serve indexed data through a production-ready GraphQL API via Hasura.
- Index across multiple chains simultaneously from a single codebase.
- Track over 1 million dynamically created contracts using factory patterns.
- Combine on-chain and off-chain data in handlers using the Effect API.
- Use wildcard topic filtering, block handlers, and custom logic on every block.
- Run locally with Docker or deploy to Envio Cloud.

## HyperSync

HyperSync provides:

- Up to 2,000x faster blockchain data retrieval than standard JSON-RPC for suitable EVM workloads.
- Native coverage across 86+ EVM chains and Fuel, with new networks added regularly.
- Flexible query capabilities: filter, select, and process exactly the data you need in one request.
- Optimized binary encoding and parallel fetching for minimal latency.
- Client libraries in Python, Rust, Node.js, and Go.
- A visual query builder at https://builder.hypersync.xyz

## HyperRPC

HyperRPC is:

- A read-only JSON-RPC endpoint specialised for data-intensive operations like `eth_getLogs`.
- Up to 5x faster than traditional nodes like geth, erigon, and reth for suitable workloads.
- Compatible with existing RPC tooling as a drop-in endpoint, no code changes needed.
- Powered by HyperSync under the hood.
- Available across numerous EVM chains with standard methods for blocks, transactions, receipts, logs, and chain data.

## Envio Cloud

Envio Cloud is the fully managed hosting platform for HyperIndex indexers:

- Git-based deployments: push to a deployment branch and the indexer builds and deploys automatically.
- Zero infrastructure management: Envio runs the servers, databases, and scaling.
- Static production endpoints with zero-downtime version switching and one-click rollback.
- Built-in monitoring: logs, sync status, and deployment health in real time.
- Alerting via Discord, Slack, Telegram, or Email.
- Security features including IP and domain whitelisting.
- Free development plans and scalable production tiers.
