The Solayer Jade Card is here with a bang! The features, use cases, and application tutorial of the U Card built on the public chain are fully revealed.

Recently, the SVM public chain Solayer announced the official launch of the Solayer Emerald Card, a financial card that settles in USDC. As a product previously promised to public sale participants, the Solayer Emerald has already launched a virtual card version. The card can be applied for in countries and regions outside of specific limitations, and it can be applied for with a Taiwanese identity. Currently, testing shows that binding with Apple Pay and LINE PAY allows for seamless transactions in Taiwan and South Korea. Additionally, according to official documentation, the amount stored on the card has an annual yield of 4-5% supported by U.S. Treasury bonds.

Solayer is backed by US Treasury bonds with an annualized return of 4%.

The Solayer Emerald Card is a Visa cryptocurrency financial card that supports Apple Pay, Google Pay, and LINE Pay. It can be used to spend and withdraw cash using $USDC, and it offers on-chain rewards. Combining physical payment with DeFi functionality, it emphasizes decentralization and instant settlement. As it is a VISA card, it can be used at merchants worldwide, and once the physical card is launched, it will support ATM withdrawals of local fiat currencies.

Using the card for purchases directly deducts from $USDC without the need for prior conversion. Depositing $USDC allows for immediate spending or conversion to sUSD to earn annualized returns of 4-5%. sUSD is a stablecoin backed by U.S. Treasury bonds, with no lock-up restrictions and no minimum threshold. It supports instant minting and redemption, operating fully on-chain and completely non-custodial.

Whitelist issuance, enter the invitation code to join the waiting list.

Basically, as long as you connect the Solana wallet to the official website (, addresses participating in the public sale can get a card for free, and the card issuance fee for addresses with Solayer airdrops is 10 USD ). Due to the official registration wanting to control the card issuance quota and the overwhelming applications, general users may not be able to open a card immediately (, meaning it is currently similar to a whitelist card issuance ). You can choose to pay 75 USD to open the card in advance or use the invitation code M2IKZC, and complete KYC (. Users in Taiwan can successfully pass ) to complete the card issuance.

Please note that each deposit will incur a 1% handling fee, meaning that depositing 100 USD will result in a 1 USD charge. For other fees, the USD transaction fee is 0.15 USD per transaction, and each international transaction incurs a fee of 0.10 USD plus 1.5%.

Currently, the official event is being held for swiping the Solayer Emerald Card, and posting about it gives you a chance to receive Layer tokens. Additionally, the second phase of the Solayer points program has been launched, where you can earn airdrops by swiping your card.

( The Solayer community fundraising heat has surged! Taiwanese users can participate, open until the morning of the 18th, with expected single number returns exceeding 200% )
