Adds Pinax to the Unichain Data Indexers page.

Pinax maintains the open source Firehose and Substreams projects alongside StreamingFast, and runs its own Unichain nodes. Firehose streams full blocks over gRPC — including call traces, internal transfers and balance changes a JSON-RPC node doesn't return — and Substreams runs Rust modules in parallel on top of those blocks.

This fills a category gap on the page: the current entries cover analytics platforms and subgraph frameworks, and there's no streaming-primitive provider listed.

Verified before submitting

Claim	Check
Unichain Mainnet	eth_chainId → 130
Unichain Sepolia	eth_chainId → 1301
Firehose, both networks	grpcurl … list returns sf.firehose.v2.Stream
Substreams, both networks	returns sf.substreams.rpc.v2.Stream

Entry format follows the existing ones — short description, getting-started link, and a ### Supported networks list. Appended at the end, matching how Dune sits after The Graph.

One thing I deliberately left out

I have not added Pinax to node-providers.mdx, even though we serve archive JSON-RPC for Unichain. That page opens with:

All third-party node providers listed below support WebSocket connections for real-time data.

Our RPC gateway doesn't serve WebSocket — a wss:// handshake returns 200 with no Upgrade header — so adding us there would make that statement false for one of the entries. Flagging it rather than quietly skipping it, in case you'd rather reword the callout or list us with a caveat.

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.

Reviewed the diff (content/unichain/tools/data-indexers.mdx, +12/-0).

• Content-only change, follows the exact structure of the existing entries (## Name → description → getting-started link → ### Supported networks), appended after Dune as described.
• No contract addresses, chain IDs, or code samples touched.
• No changes to existing links; new external links point to pinax.network / app.pinax.network (new domain for this repo) — content is internally consistent with existing mentions of Substreams elsewhere in the docs (unichain/guides/routing-on-unichain.mdx), but I wasn't able to make outbound network calls in this sandbox to verify the pages are live/accurate, so a quick manual click-through on those links is worth doing before merge.
• MDX syntax, headings, and frontmatter are all well-formed; no build-breaking issues found.
• No spam/promotional red flags — matches the tone of other vendor entries on the page.

Nothing blocking from a docs-accuracy standpoint.
