# Covalent | PubFi Discovery

> Covalent is tracked as an on-chain state source for Ethereum coverage. Unified blockchain data API for balances, transactions, token holders, NFTs, and decoded chain state.

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 readiness: not_routeable (PubFi gateway not routeable yet)
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.

- Decoded on-chain state reads
Not ideal for candidates:
- RPC endpoint hosting
- Primary exchange order books
Use case candidates:
- Read balances and transactions for portfolio workflows
- Compare decoded chain-state APIs for application data
