I've seen many friends find the new features of the Solayer Jade Card particularly useful. This sub-card function essentially bridges crypto and lifestyle, bringing the traditional bank card splitting logic onto the blockchain, and it uses a single mnemonic phrase to manage multiple accounts. Specifically, my understanding of this function is that with one mnemonic phrase, you can generate an unlimited number of sub-cards, each of which can have custom labels, limits, and purposes. It basically transfers the logic of bank supplementary cards to stablecoin accounts, but in a decentralized manner. Compared to other U cards, I feel that the Jade Card currently has these two advantages: - Direct consumption of USDC, supporting Apple Pay/Google Pay, especially for deposits converted to sUSD, allowing for withdrawals at any time while earning 4-5% annualized returns. - Earn points on every purchase, which can be exchanged in the future for $LAYER airdrops and partner benefits, essentially equating to expected cashback from U cards. Currently, the Jade Card offers free/discounted activation benefits for early community users (Genesis airdrop or public sale participants), while regular users have a $75 reservation fee. KYC is very simple, and both Chinese ID cards and passports can pass. Spending can also accumulate Season 2 points, but I wonder if the points airdrop can be larger.
