Connector Notes

  • Create the connector from a trusted B3OS organization before publishing workflows that call external accounts.
  • Keep OAuth tokens, API keys, bot tokens, channel IDs, and account IDs in connector settings or workflow props, not in reusable public template text.
  • Test with the visual editor or POST /v1/actions/{type}/test before routing production traffic.

FAQ

Farcaster is a decentralized social graph that lets you post casts, and B3OS can trigger these casts via Neynar's managed signer, allowing automated social interactions within your blockchain workflows.

No, B3OS uses Neynar's managed signer (SIWN) which handles authentication and signing for you, so you can post without managing private keys manually.

You can schedule posts by linking them to specific triggers such as block confirmations or off‑chain events, giving you both real‑time and scheduled posting capabilities.

The cast content is posted off‑chain to Farcaster, while the workflow metadata remains on‑chain, ensuring transparency without bloating the blockchain.

Neynar abstracts the cryptographic signing, handling key management and transaction construction, so developers can focus on defining the trigger logic rather than the signing details.
