Recently, many people have been promoting the Plasma card. If you don't have any other useful cards, you can definitely try it, but you may know the following before using it. The following is Ai's opinion based on my needs, for reference only. Plasma One Card is a Visa debit card launched by Chain Technologies Research, featuring "native stablecoin payments" (recently updated frequently on the Apple App Store). The underlying chain behind it is the Plasma Layer 1 blockchain, which has recently gained popularity around USD ₮ _0 (zero gas fee Tether). If we define it in one sentence: it is essentially the same type of product as RedotPay and http://(Crypto. com), but it wraps a better story with "unmanaged wallets" and "balance sheet earnings". Since you are extremely sensitive to the "shanzhai flavor" and "high friction" of this type of card, we can completely strip it of its official marketing rhetoric and use a critical professional eye to penetrate its underlying logic, cost traps, and potential "pitfalls". 1、 Its official selling point (why does it sound tempting?) 1. Claimed to be "Self Custody": Officially claimed to be an unmanaged wallet, with the private key on your device and no one else able to access your money. 2. Deposit and earn interest: You put stablecoins inside, and in the last second before swiping the card for consumption, these idle funds are helping you earn profits. Real time settlement during consumption: supports direct deposit of stablecoins, binding with Apple Pay, and real-time acceptance of fiat currency consumption at 130 million Visa merchants worldwide. 2、 What are the pitfalls of "hardcore nitpicking" from a professional perspective As an investor with extremely high requirements for quota and friction costs, this card is likely to still belong to the category of "counterfeit toys" in your eyes. There are four reasons for this: 1. The False 'Self Custody' Paradox Pain point: This is where it has been criticized the most (such negative reviews have recently appeared on the App Store). Truth: The "self custody" on cryptography and blockchain naturally conflicts with the "centralized clearing" of traditional fiat bank cards. Visa cannot directly deduct your assets in real-time on a purely decentralized chain. To enable card swiping, your assets must first be held in custody with its compliant issuing partner (Partner Bank/Custodian). So, the so-called 'unmanaged' is at most a pseudo concept of front-end wallet shells, and the underlying layer is still completely centralized. 2. The wool of "financial income" comes from the sheep Pain point: Putting money inside can generate interest, which sounds beautiful, but there is no free lunch in the world. Truth: The underlying source of these profits is likely to be investing your stablecoins in some on chain DeFi protocols, or buying tokenized US Treasuries (RWAs). This means that the working capital you deposit for daily card swiping inadvertently bears the financial risk of underlying protocols being hacked, unanchored, or the intermediary of the issuing bank running away. This is not much better than http://(Crypto. com), which allows you to pledge platform coins, as it is all about betting on meager returns with safe principal. 3. Hidden exchange rate friction and "pumping from both ends" Pain point: Although it may promote "zero card transaction fee", how does it make money? Truth: The core profit of encrypted cards comes from the spread of exchange rates. Even if it eliminates the explicit FX Fee, at the moment of consumption deduction, the exchange rate it gives you for stablecoins against Hong Kong dollars and Singapore dollars will definitely be 1% to 2% lower than the international bulk exchange rate. In addition, its fund inflow and outflow (On ram/Off ram) heavily relies on third-party gateways, and recharging or withdrawing will incur significant tiered transaction fees. 4. Unable to provide the high credit limit and stability you need Pain point: As a newly launched project that mainly relies on virtual cards and Apple Pay to crack down on users, its compliance foundation is very weak. Truth: These types of cards, due to the lack of strong assets and risk control endorsements from traditional commercial banks, can easily trigger Visa's anti money laundering risk control measures and result in chargebacks in the event of large transactions (such as tens of thousands of dollars per transaction). And as a new channel, it may suddenly shut down overnight due to compliance issues from upstream issuing banks at any time. final conclusion Plasma One Card still hasn't jumped out of the "Web3 traffic card" cutting leek logic.
