This Emerald Card is amazing, brothers! I tested it myself, and it allows for quick QR code payments, just like Alipay. You can bind it to Apple Pay and directly pay 9.9 for milk tea using USDT, covering all daily spending scenarios. Not only that!! The USDT stored on this card also earns an annual yield of 4%, completely bidding farewell to traditional banks!

Now when you open a card, you can also receive BTC airdrops of 10-100u, and for every 1u spent, you earn 1 point. Points can be exchanged for airdrops and whitelist spots, making it a great opportunity for crypto enthusiasts. If you are in the crypto space, there’s no reason not to get this card!

Here are my thoughts on Solayer:

Solayer is not just 'the next public chain'; it is a user operating system for on-chain finance.

While many projects are still focused on TPS and narratives, Solayer is doing something simple yet important: making on-chain finance 'usable', 'accessible', and 'profitable'.

01 sUSD: The second layer evolution of stablecoins

Regular stablecoins are just asset docking points, while sUSD is a digital savings account with yields. An annual yield of 4%, pegged to U.S. Treasury bonds, with transparent on-chain earnings and automatic compounding. The expansion from Sidekick Labs to Base proves that it's not only useful but also building a complete circulation network.

02 Emerald Card: A credit card that earns rewards and can be easily used

The Emerald Card is not about 'creating another traditional card', but redefining the crypto spending experience:

– Deposit USDC → Automatically earn Treasury bond yields

– Spending → Globally available (Visa supported)

– Benefits → Enjoy Nansen discounts, BTC airdrops, CHAOS event rewards

One card connects on-chain earnings with real-world spending. Solayer makes using cryptocurrency a daily routine instead of a challenge.

03 InfiniSVM: Not just fast, but fast service for financial needs

The goal of the InfiniSVM built by Solayer is >1M TPS, not to showcase technology, but to support massive calls in financial scenarios. Compatible with SVM, equipped with hardware acceleration capabilities, and having acquired Fuzzland's security stack, Solayer is more like building a high-performance platform specifically for financial services and developers.

04 Solayer = Wallet + Earnings + Payments + Public Chain

You can use it to save money (sUSD), invest (SOL staking), spend (Emerald Card), and build (InfiniSVM). That's why I say it’s not just a chain, but a set of on-chain financial operating systems.

Web3 lacks new public chains, but Solayer provides us with a 'usable on-chain living system'. If DeFi is financial Lego, then Solayer is like providing you with a complete set of financial tools, ready to use with immediate returns.
