American Express (Amex) officially unveiled a new blockchain innovation that connects traditional financial services with digital identity solutions. The company announced the launch of blockchain-based passport stamps built on Base, Coinbase’s Ethereum layer-2 scaling solution.

The initiative allows travelers to collect digital passport stamps recorded securely on-chain, representing travel history, loyalty achievements, and personalized rewards. By leveraging blockchain, Amex ensures that these digital stamps are tamper-proof, transparent, and portable across multiple platforms.

According to Amex, the system is designed not only to enhance customer experiences but also to strengthen loyalty programs by creating a verifiable record of users’ activities. Each stamp can also be integrated with reward mechanisms, NFT-based perks, and even exclusive travel-related offers.

Industry observers highlight this as a significant step for bridging traditional finance (TradFi) with blockchain ecosystems. By choosing Base, Amex taps into a secure, low-cost, and scalable infrastructure, making Web3 utilities more accessible to mainstream users.
