This emerald card is simply a 'walking wallet'! In the past, we had to exchange currency when traveling abroad, but now with the emerald card, you can bind it directly for spending! Whether using U or other methods, there's no need to wait for the 'currency exchange' step. It's just like scanning a QR code on WeChat to pay; with a beep, the money is transferred—quick and safe! Plus, this card is incredibly versatile; whether it's ordering food, shopping online, or subscribing to ChatGPT, or buying a Twitter blue tick, a simple click solves everything—no more worrying about 'does this software support payment'!
Let's talk about making money! Converting USDC to sUSD can earn you a steady 4% annual return! What does that mean? It's like putting in $10,000 and getting an extra $400 in interest after a year! That's so much better than the pitiful interest from a regular bank account, which might only yield a few bucks after a year. Moreover, this return is tied to government bonds, making it highly stable. sUSD can be spent directly without conversion, and spending can also earn points, which can be exchanged for airdrops, gifts, etc.
What's even better is that if you have SOL in hand, you can stake it to receive airdrops and earn points! It's like taking your idle old items to a recycling station; not only do you free up space, but you also get some small gifts or snacks in return! These points can be exchanged for various benefits, rounding up to essentially free goodies!
I was an early participant and staked 2 SOL, and I genuinely benefited from it! Solayer is not one of those inflated projects with empty promises. It's a 'upgraded version' specifically designed for the Solana ecosystem, much like renovating an old neighborhood. Nowadays, blockchain transactions can sometimes be slow and laggy. Solayer's InfiniSVM technology is like installing a super-fast 'new engine' in a computer, upgrading both the hardware and optimizing the software, aiming to make transaction speeds soar—processing over 1 million transactions per second! In the future, transfers and trades will be as fast as sending a message!
