No wonder LAYER has been rising recently, it turns out Payfi products are out! This Emerald Card produced by @ solayer_1abs is actually a very ambitious product. It is not only an encrypted bank card for "card swiping consumption", but also a combination of a cross chain identity system (SolanaID), DeFi revenue account, and on chain reputation platform. From my perspective as a seasoned financial driver and cryptocurrency enthusiast, it represents a closed loop of on chain identity binding, off chain consumption scenario implementation, and eFi revenue integration. Let me break it down and explain. First, let's talk about the core advantages of this card: one ️⃣ Global universal+mainstream payment integration • Supports usage in over 100 countries; Integrated with Apple Pay and Google Pay, it can be used on most NFC enabled terminals worldwide; ATM withdrawal is equivalent to entering the offline payment scene; For users, using on chain assets for payment means there are no boundaries, and assets flow at any time. two ️⃣ On chain assets → Real US dollar consumption Cardholders only need to recharge USDC, and the system will complete the USDC-USD Visa settlement; Similar to using stablecoins from DeFi wallets to swipe real-life credit cards; No need to manually transfer funds through OTC or CEX, greatly reducing the difficulty of fund inflow and outflow. three ️⃣ Optional access to treasury bond bond income products (sUSD) Deposit USDC and choose to participate in 4% USD treasury bond yield products; Your card assets can not only be spent, but also steadily appreciate; Equivalent to a bank card that can earn interest. four ️⃣ Binding Solana ID - Establishing an on chain reputation system Bind different on chain addresses through SolanaID to establish a "unified identity"; The system tracks your on chain trading behavior and provides a reputation rating; The higher the reputation, the more rights, airdrops, privileges, and privileges may be obtained; Essentially, it is building a "on chain credit system" for Web3. five ️⃣ The encrypted reward system that will be launched in the future • Consumers receive encrypted rewards (such as: LAYER rebate NFT、 Project airdrops, etc.); Upgrade the credit card points system to an on chain incentive ecosystem; Unlike traditional bank points, these rewards are tradable, participate in governance, and have added value. Have you noticed that major project parties and exchanges have been making efforts in the Payfi field recently? Why do everyone actively participate in Payfi now? Because Web3 currently lacks a 'global credit reporting system on chain', the essence of the rapid development and prosperity of traditional Web2 finance and modern finance is actually the prosperity of the credit market. Web3 urgently needs to make up for this shortcoming. By building the Payfi system and implementing the Web3 version of credit score, you can achieve your credit rating through the "reputation" and "participation history" on the chain. In the future, more Web3 financial innovations can be developed, such as lending credit, cross chain whitelists, on chain employment certificates, etc. The opportunities are self-evident. As the largest public blockchain in the United States, SOL will bring the greatest opportunities and future benefits, which is worth looking forward to! 🧐
