Manifest (CLI)

Generate account association credentials with the CLI

Generate your Farcaster account association credentials.

Terminal

npx create-onchain --manifest

Follow the prompts to connect your Farcaster custody wallet, add your deployed URL, and sign. The CLI writes FARCASTER_HEADER, FARCASTER_PAYLOAD, and FARCASTER_SIGNATURE to your .env.

Update the same variables in your deployment platform.

While testing, set noindex: true in your manifest to avoid indexing.

Create farcaster.json

Serve the /.well-known/farcaster.json endpoint
