Using Unlock Protocol, we implemented a blockchain-based ticketing solution for Ethereum México 2023. 

## This enabled us to:
- Register everything on-chain: All ticket transactions and ownership were transparently and securely logged on the Ethereum blockchain via Arbitrum, Polygon, and Optimism networks.
- Receive crypto as payment: Attendees could purchase tickets using cryptocurrency, streamlining the payment process and reducing transaction fees.
- Contact attendees: Post-event engagement was facilitated by utilizing blockchain data to identify and communicate with event participants, enhancing our community interaction and feedback collection.
- Onchain swag: We also used Unlock Protocol to tokenize the official t-shirts from Ethereum Mexico 2023: https://opensea.io/collection/swag-conmemorativo-ethereum-mexico-2023-arb
