American Express has introduced Ethereum-based ‘travel stamps’ to create a commemorative record of travel experiences.

The travel experience tokens, which are technically NFTs (ERC 721 tokens), are minted and stored on Coinbase’s Base network, said Colin Marlowe , VP, Emerging Partnerships at Amex Digital Labs.

The travel stamps, which can be collected anytime a traveler uses their card, are not tradable NTF tokens, Marlowe explained, and neither do they function like blockchain-based loyalty points – at least for the time being.

“It's a valueless ERC-721, so technically an NFT, but we just didn't brand it as such. We wanted to speak to it in a way that was natural for the travel experience itself, and so we talk about these things as stamps, and they're represented as tokens,” Marlowe said in an interview.

“As an identifier and representation of history the stamps could create interesting partnership angles over time. We weren't trying to sell these or sort of generate any like short term revenue. The angle is to make a travel experience with Amex feel really rich, really different, and kind of set it apart,” he said.

Fireblocks is also involved, supporting Amex as its Wallet-as-a-Service provider for the passport product, a Fireblocks representative said.

The Amex travel app also includes a range of tools for travels and Centurion Lounge upgrades, the company said.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
