Peak market value of 230 million US dollars; Binance+Coinbase+Upbit, Grand Slam on the Shanghai Stock Exchange. That's right, it's the Defi App (home). Now, @ doranmaul, the former growth director of Defi App, has started a new project: http://artisan.cash . 1/Parasite first, then backfire Stablecoins have almost completed the first half of payment: issuance, clearing, and cross-border transfers. Transferring a USDC on the chain takes a few seconds and the cost is also very low. But the problem is that payment has two ends, and being able to transfer money does not necessarily mean being able to consume. And today's stablecoin payments are stuck in this loop. The vast majority of real-world merchants are not willing to directly accept on chain USDC, USDT, or other stablecoins. Allowing merchants to install wallets, manage private keys, and bear compliance risks? unrealistic; Building a new merchant acceptance network from scratch to replace Visa? Even less realistic. So the most rational path for stablecoins at present is not to be rigid, but to parasitize on the old network first. This is not a unique strategy of stablecoins, but a recurring pattern in the payment industry. PayPal did not have its own clearing network in the early days and initially relied on credit cards and ACH; ▄ Alipay initially also connected to the bank card system, starting from the payment experience, and then gradually expanding its own network. The answer to the current version of stablecoin payment is actually very clear, which is the U-card. Why is U-card the optimal solution? The essence of a U-card is a currency converter. You hold stablecoins, and at the moment of swiping the card, the issuer will exchange it for fiat currency in the background to settle with the merchant. The merchant will still follow the same process as Visa/Mastercard, and there is no need to change anything. Its true value lies in two points. Unconscious: Users spend stablecoins, while merchants receive fiat currency, and neither party needs to change their habits. Action merging: The traditional path is to sell coins → withdraw to the bank → consume, with three actions, two waits, and at least one KYC friction. Press it into one action with the U-card. Of course, U-cards have not eliminated costs, as Visa's interchange, issuing bank fees, and fiat currency exchange spreads are all still present. Its short-term value lies in the innovation of the experience layer, rather than the innovation of the cost structure. The real cost advantage may not come until the day when it is possible to bypass card organizations and directly connect merchants. What does Artisan want to verify? Artisan's idea is to bring the concept of "users paying stablecoins and merchants receiving fiat coins" into more daily scenarios. Pay the bill: You pay USDC, and the landlord receives USD. Swipe card consumption: You swipe your Artisan card and the supermarket receives US dollars. Transfer money to a friend: You transfer USDC, and the friend receives USD on Venmo. Users do not need to sell or withdraw coins every time they make a purchase; The payee does not need to learn how to use the wallet or accept on chain tokens first. Stablecoins no longer have to be an 'asset that all merchants are willing to accept', but have been retired to the backend and become the underlying asset that supports daily payments. Finally, the U-card may not be the endpoint of stablecoin payments, but it is a practical bridge. Expectation http://artisan.cash Open beta testing.
