# Helius | PubFi Discovery

> Helius is tracked as an on-chain state and NFT source for Solana coverage. Solana data and RPC platform for enhanced transactions, DAS, webhooks, NFTs, and account data.

Source: Discovery catalog fixtures consumed by the public Discovery routes.
Format: text/markdown; charset=utf-8
Inclusion gate: source.isIndexable is true; draft/noindex records are not emitted as markdown detail pages.
Canonical SEO rule: the HTML detail page is the canonical SEO URL; this Markdown route is an agent-readable mirror.
Agent availability rule: raw claim-safe status is preserved for provenance, but actionability uses effective agent availability. Degraded pages require revalidation even when the raw status names a gateway, x402, or MCP surface.

PubFi gateway summary: This Discovery source is available for source evaluation and comparison, but PubFi does not publish a production-callable gateway route for it yet. Use this page to compare the provider, signal demand, or start a procurement/integration review instead of attempting a PubFi gateway call.
PubFi gateway guidance:
- Do not infer a PubFi gateway path from this Discovery page.
- Use the official provider docs for direct provider integration until a PubFi readiness entry marks this source gateway_available.
- Use the Discovery request or demand-signal CTA to register integration interest with PubFi.
- Supplier procurement, paid-plan approval, and upstream credential setup require explicit review before PubFi can route the source.

Key facts:
- Primary coverage: Solana data, RPC, enhanced transactions, DAS, webhooks, NFTs, and account data (source https://www.helius.dev/)
- Fixture coverage: On-chain state and NFT coverage for the Solana fixture target (source https://www.helius.dev/)
Best for candidates:
- Solana application data enrichment
- NFT and account data workflows with webhook needs
Not ideal for candidates:
- Ethereum-only RPC comparisons
- Broad exchange market data
Use case candidates:
- Add Solana NFT and account context to applications
- Evaluate webhook-capable Solana data infrastructure
Implementation note metadata:
- auth severity medium
