xion-oauth2

OAuth2 authentication skill for Xion blockchain development. This skill enables AI agents to authenticate with Xion's MetaAccount system using browser-based OAuth2 flow with PKCE security.

Why MetaAccount?

MetaAccount authentication provides:

• Gasless transactions - No need to hold XION for gas fees
• Browser-based login - Familiar OAuth2 flow, no mnemonic management
• Session keys - Secure, revocable access tokens
• 30-day refresh tokens - Long-lived sessions for automation

⚠️ Refresh-First Authentication

ALWAYS prefer auth refresh over auth login when you have existing credentials.
