At 11 PM, saw a post on Binance Square saying 'Your bank card has been frozen.' 50,000 yuan instantly 'evaporated', this is not a movie plot, but a financial predicament that more and more people are experiencing. As traditional bank accounts are often frozen due to 'suspicious transactions', tens of thousands of users worldwide have quietly switched to the Emerald Card, an on-chain Visa card that comes with a 'freeze protection buff', redefining payment freedom in the digital age.
The Emerald Card is jointly created by the decentralized payment protocol Nubit and the high-performance public chain Solayer, with its core freeze protection mechanism targeting the fatal weakness of traditional bank cards:
• Transparent and traceable on-chain ledger: Each transaction is recorded on-chain in real-time through the Bitcoin Thunderbolt protocol, with immutable and open verification transaction records, completely bidding farewell to 'suspicious transaction' labels;
• Intelligent risk control preemptive interception: The system automatically analyzes transaction patterns, providing early warnings for potential risk operations, avoiding misjudgment freezes from the source;
• Compliant stablecoin settlement: Consumption is directly deducted from sUSD (a stablecoin fully backed by U.S. Treasury bonds), with the fund path fully compliant with regulatory frameworks, eliminating the risk of 'dirty money contamination'.
InfiniSVM hardware-accelerated chain: Dedicated hardware allows for a transaction throughput of 1 million TPS, crushing Visa's global peak of 65,000 TPS;
Real cases show that users making cross-border payments of $8,500 triggered risk control freezes on traditional bank cards, while the Emerald Card completed verification and release within 10 minutes thanks to on-chain transparency.
The Emerald Card converts daily payments into stable yield backing: sUSD in the card enjoys an annual yield of 4%-5%, which is 20 times that of bank savings interest rates.
• Dual benefits from points airdrop: For every $1 spent, accumulate Emerald points that can be redeemed for token airdrops, Starbucks vouchers, etc.;
• Zero friction crypto payments: Supports global VISA merchants + Apple Pay/Google Pay, with USDC settled directly without exchange loss, saving 1.5% currency conversion fees on cross-border purchases.
