In 2025, blockchain will still be a hot topic; but today, I was struck by a sentence: 'You trade coins, but regulators are looking at how you cash out.'

This is not alarmist. In today's environment of increasing regulation and strong KYC ties, every card you use and every on-chain transfer you make leaves 'behavioral traces'. Amidst this wave of regulatory anxiety, a project being heavily promoted by Binance Square—Solayer—stands firmly on the controversy point with a product suite that bridges 'on-chain finance with reality'.

This article is my panoramic review and a bit of anxiety venting as a user.

🔧 What is Solayer?

Solayer is a new high-performance Layer 1 blockchain built on Solana, aimed at one goal: infinitely scalable on-chain financial infrastructure.

The core technology system of this project is called InfiniSVM, which aims to break through the current ceiling of SVM (Solana Virtual Machine) in terms of processing speed, security, and sharing. The white paper claims that future TPS (transactions per second) will exceed 1 million, which is a hundred times that of the ETH mainnet.


You can think of it as 'an enhanced version of the Solana system that runs faster than Solana'.


But what deserves more attention is not the technology, but the product matrix and real-world connection points built around this core.

💳 Emerald Card: The 'first card' for blockchain finance to land in reality?


The most eye-catching product of Solayer is the 'Emerald Card'. This card resembles a traditional bank Visa card but is linked to on-chain assets (USDC/sUSD), allowing for global consumption and online/offline payments, as well as cashback.


Doesn't it sound familiar? Yes, it resembles a certain Web3 version of 'Huabei + cash card'.


Even more astonishing is:

Deposits in USDC within the card enjoy a 4% annual yield, claiming to be linked to U.S. Treasury bonds.

The tipping, shopping, and rebate systems are complete; every swipe of the card has an on-chain record.

Collaborating with Nansen and Nubit, users can receive BTC rewards, member discounts, etc.

In summary: Solayer stitches together 'DeFi + Visa + marketing points system' into an on-chain card that can be used to buy coffee at supermarkets.

🧠 sUSD and the on-chain tipping system: When you give others money, you are also participating in the protocol.


sUSD is a stablecoin system created by Solayer, claiming to be pegged to U.S. Treasury bonds, providing stable returns, and allowing tips to creators.


You read that right, this is not simply a payment function, but Solayer is trying to create a 'token-driven content ecosystem on-chain':

Users can directly tip authors using sUSD via the Emerald Card or wallet.

Tip givers can receive airdrop points, while content creators receive protocol rebates.

This mechanism has already been implemented at Sidekick Labs, where the tipping button directly calls the wallet without going through a centralized platform.

But here comes the problem: Does your tip participate in 'distributed asset circulation'? Does it touch the boundaries of financial compliance?


To facilitate understanding, we have organized the recent key events of Solayer as follows:


But the problem lies here.

On one side is the transparency and openness of the on-chain structure; on the other side is the ambiguity and unclear boundaries of real-world regulation.

  • Who issues the Emerald Card? Is it compliant with regulations?

    Is the yield structure of sUSD auditable? Does it have stable reserves?

    Does the act of tipping constitute a transfer of funds?

    Is the cross-chain Wormhole structure beyond the reach of judicial control?

    It’s hard for ordinary users to judge and trace. Does the promotion of such projects by Binance Square in the form of essays imply 'platform endorsement'? Or is it the user's own responsibility?

🗣 In conclusion: I'm not here to rain on your parade; I just want to ask one thing.


You may not trade coins, but every on-chain product you use could become 'a loophole in your intersection with the real financial system'.


Is Solayer a good project? The technology might be impressive, but how far can it be implemented?

Will I continue to use the Emerald Card? Maybe, but what I care more about is:


If one day regulators ask me: 'Where did the USDC you used for your card come from?'

What explanation can I provide?
