Clerk-Crossmint-Supabase Integration Flow

To sync Clerk authentication with embedded Crossmint wallets and Supabase, this pattern provisions multichain wallets on login and uses a Supabase edge function to persist user addresses. It connects Clerk identity to non-custodial Crossmint wallets for Solana and EVM chains.

Yes, you can automatically provision multichain wallets when a user signs in with Clerk. This integration pattern triggers Crossmint embedded wallet creation across Solana and Ethereum-compatible networks upon successful authentication, enabling a single-login experience.

The best way to persist Crossmint wallet addresses in Supabase is by using an edge function. This integration pattern includes a Supabase edge function that stores multichain wallet addresses and mappings, ensuring database-backed persistence for auditability and seamless user experiences.

Yes, this authentication pattern supports both Solana and EVM chains. The Crossmint embedded wallet integration provisions non-custodial keys across Solana and Ethereum-compatible networks like Base and Polygon, with gas sponsorship for multichain transactions.

Yes, you can use this integration pattern for applications requiring gas sponsorship. It provisions Crossmint embedded wallets with gas sponsorship and non-custodial keys across multichain environments, linking Clerk identity to Supabase-backed persistence.

The Clerk and Crossmint multichain wallet integration is highly extensible, providing a reusable blueprint for adding new wallets or chains. It can also adapt to different auth providers while maintaining Supabase data persistence.
