Summary

Brings the Supported Networks pages in line with networks registry v0.8.8 (the Oct 21 deprecations), removes outdated chain-count claims, and refreshes the per-network pages to default to Subgraph Studio and The Graph Market, with "Get API Key" CTAs.

Registry v0.8.8 deprecations

• Removed custom pages for networks that no longer appear in the table: Fuse, Fuse Testnet, Kaia, Kaia Kairos, NEAR, NEAR Testnet, Viction, zkSync Sepolia
• Removed the NEAR Subgraphs guide (Studio support for NEAR was removed)
• Added nginx.conf redirects from all removed pages, the NEAR guide, and its legacy aliases to /supported-networks/
• Updated route-lockfile.txt

Chain-count claims

• Removed "60+ chains/networks" from the homepage hero, the homepage Supported Networks section, and the About page
• Replaced "dozens of chains" with "many chains" in the Gateways overview
• The "See all N networks" count on the homepage is still computed from the registry

Network details table

• Subgraphs row: Payments: Subgraph Studio / Indexing: The Graph Network | Community Support | Subgraph Studio, matching each network's tag in the table
• Substreams row: one Full Service: provider; The Graph Market is preferred, with Pinax only where the registry has no The Graph Market endpoint. Data Nexus is never listed (it's available through The Graph Market)
• Chain Docs row: shows "[Chain] Docs" instead of the raw URL
• Rows are right-aligned; the network title uses the h2 size

Subgraphs section (community template)

• Default flow is now the Subgraph Studio UI: create in Studio → graph init → graph deploy → publish from the Studio dashboard → query with an API key
• Networks without Studio indexing (driven by the registry, not per-page props) show a warning plus the registry's backstop description, e.g. "InfraDAO provides indexing support for all published Subgraphs with 500+ GRT in signal on Anubis Mainnet."
• Curation signal recommendation follows the registry: 1,000 GRT on networks with indexing rewards, 500 GRT on community-only networks
• New "Search Graph Explorer for Existing Subgraphs" section (hidden on BSC/Polygon, which have their own)
• Steps 2 and 3 consolidated into single commented code blocks
• Local verification now uses Graph Node Dev Mode (gnd) instead of docker-compose Graph Node
• Copy edits throughout; removed the network value callout

Page-wide changes

• "Supported in two ways" intros: bold product names, new Subgraphs/Substreams copy, The Graph Market as the listed provider
• Headings one level larger; page breaks before the Subgraphs, Substreams, Find Existing Subgraphs, and Guides sections
• "Get API Key" GDS button beside every "Indexing [Chain] with Subgraphs/Substreams" heading (Subgraph Studio API keys / The Graph Market) and "Explore" beside "Find Existing Subgraphs" (Graph Explorer)
• Guides cards no longer force a fixed min height
• NON-EVM table chip uses the GDS solar yellow to sit alongside the turquoise BASE and green EXTENDED chips

Fixes

• Hydration error on Studio-indexed network pages (nested <p> in MDX)
• Raw markdown links rendering as text in the Substreams templates' API key step
• Arc now lists The Graph Market (added in the registry) and uses it for API keys

Implementation notes

• New NetworkContext passes the registry network to custom-content partials, so templates branch on registry data (Studio indexing, backstop description, rewards) instead of hand-set props
• New GetApiKeyButton.tsx (ProductSectionHeading, ExploreSectionHeading)
• customContent/README.md documents the Subgraphs partials and the CTA headings

Review checklist

• /supported-networks/mainnet/: rewards network, Studio flow, 1,000 GRT tip, The Graph Market only
• /supported-networks/injective-evm/: community-only, warning + StreamingFast description, 500 GRT tip
• /supported-networks/arc/: Studio-only template, The Graph Market + Pinax in intro
• /supported-networks/bsc/: BSC headings, Explore button, page breaks
• /supported-networks/bitcoin/: non-EVM Substreams-only page
• /supported-networks/: NON-EVM chip color
• Redirects (nginx only, not in pnpm dev): /supported-networks/kaia/, /subgraphs/guides/near/
