Pages that compare RPC providers include a disclosure banner. Links to Supanode carry rel="sponsored" on comparison pages.

Content policy

Every fact on this site comes from official sources: Solana documentation, validator source code (anza-xyz/agave), and provider public pages. Sources are listed at the bottom of each page.

Code examples are tested against devnet or mainnet (read-only methods). If we cannot verify a fact, the page stays in draft.
