Identity

Individual identity

The Optimism Collective represents individuals using unique identifiers generated through the Farcaster protocol id registry (opens in a new tab). This system ensures a secure approach to identity management within the collective.

Registering a User ID

To obtain a unique identifier:

1. Use the Farcaster Id Gateway (opens in a new tab)
2. Use the Warpcast app, which:

• Creates a new custody address
• Acts as a wallet

Making Attestations

When you make attestations about individuals:

• Leave the recipient address blank
• Enter the users id into the attestation metadata
