Many friends think that the new feature of Solayer Jade Card is particularly practical. This sub card function basically connects crypto and lifestyle, moving the traditional bank card's distribution logic to the chain, and using a set of mnemonic words to manage multiple accounts I understand the specific operation of this function as follows: with a set of mnemonic words, an infinite number of sub cards can be generated, and each card can be customized with tags, limits, and uses. Basically, the logic of the bank's subsidiary cards is moved to a stablecoin account, but decentralized Compared to other U-cards, I feel that Jade Card currently has these two advantages -Direct consumption in USDC, supporting Apple Pay/Google Pay, especially when converting deposits to USD, can earn 4-5% annualized income at any time for deposits and withdrawals -Every purchase earns points, which can be redeemed for LAYER airdrops and partner benefits in the future, basically equivalent to expected U-card cashback At present, the emerald card has free/discount activation benefits for early community users (Genesis airdrop or public sale participants). Ordinary users have 75 pre booking fees. KYC is very simple. countrymen ID cards/passports can pass. They can also save Season 2 points for consumption. I wonder if airdrop can give more points
