Thanks for contributing to Uniswap Docs! 🦄

Quick heads up on how this repo works: the docs you see on developers.uniswap.org are built from a separate source repo. When we accept a change here, we port it over there, so your fix might show up on the live site before it lands in this repo.

Updates to this repo come in batches on a regular cadence. When yours is included, you'll be credited as a co-author on the commit, so the contribution counts on your GitHub profile and in Uniswap/docs.

We review every PR but can't merge everything. Either way, someone from the docs team will follow up here once we've taken a look.

One legal bit: by submitting a PR you agree your contribution is licensed under the repo's MIT license.

Review summary

Content-only addition to content/unichain/tools/data-indexers.mdx — no contract addresses, chain IDs, or frontmatter changes involved, so risk here is low.

• Placement/formatting: Correctly inserted alphabetically between Allium and GhostGraph, and matches the structure of every other entry on the page (H2 name, description, "To get started" links, ### Supported networks list).
• Links: https://envio.dev/, https://docs.envio.dev/docs/HyperIndex/quickstart, and https://docs.envio.dev/docs/HyperSync/overview all point to the expected Envio domains and look legitimate; I wasn't able to make outbound HTTP requests in this environment to confirm live 200s, but nothing looks suspicious or mismatched.
• Technical accuracy: Description of HyperIndex (config-driven contract/event indexing, TypeScript handlers, GraphQL API, self-host/Envio Cloud) and HyperSync (direct filtered block/log/tx access) is accurate and consistent with how Envio's own docs describe these products.
• Supported networks: Only "Unichain Mainnet" is listed (other providers on this page list both Mainnet and Sepolia Testnet). This is intentional per the PR description, which cites Envio's HyperSync supported-networks page as only listing Unichain Mainnet — not a discrepancy.
• Grammar/typos: None found.
• Spam/promotion: Author discloses affiliation with Envio; content is factual and in the same style as other self-submitted provider entries on this page, not promotional filler.

No issues found — looks good to merge from a docs-correctness standpoint.

Hey @ocandocrypto-uniswap, this adds Envio to the Unichain data indexers page. Short review (~2 min). Lmk if you require anything further on our end.

Closing in favour of #1164, which makes the same change.
