As more bots and burner accounts flood online platforms, developers need a reliable way to distinguish legitimate users from throwaway accounts and spam before a transaction or task moves forward.

That’s why we partnered with the Neynar team to build the Neynar Farcaster Data Oracle, an open-source implementation compatible with Newton Protocol, enabling developers to verify Farcaster user legitimacy through programmable policies before transactions execute. This gives apps and agents a lightweight way to enforce trust requirements without relying on brittle, app-level checks.

Bringing Farcaster Identity Data into Newton Protocol

The Neynar Data Oracle allows developers to bring Farcaster user metadata (e.g., user score, follower count, verified addresses, account badges) into a Newton Protocol policy, where it enforces pre-transaction decisions. For example, a policy can require a minimum user quality score, at least one verified external wallet address, and a minimum follower count before a task or transaction is allowed to proceed. 

Also, because this logic lives in the policy layer rather than in smart contracts, developers can update these thresholds and rules over time without redeploying contracts or rewriting application code.

What Developers Can Build With This

The Neynar Data Oracle unlocks proof-of-humanity guardrails such as:

  • Anti-sybil controls: Prevent low-score or unverified accounts from interacting with key flows.
  • Task & reward gating: Only accept submissions from accounts with a minimum Farcaster reputation.
  • Community or governance moderation: Enforce participation criteria (e.g., verified accounts only) without central gatekeeping.

Composable with other Data Oracles

Neynar data is just one input into a Newton Protocol policy. Developers can combine it with any other Newton Protocol data oracle, such as:

  • Veriff or Persona for address verification 
  • Etherscan for gas fee guardrails
  • Vaults.fyi or Massive for market and asset signals
  • Magic Labs for authentication and wallet security

Get Started

Developers can now use the Neynar data oracle to bring Farcaster identity and reputation signals into their onchain apps. Head to the Developer Docs to learn how to integrate Farcaster user data and other data oracles into a Newton Protocol policy.
