Our most popular series Coins Under $1 continues this month with 3 more great choices. This time we have 2 Layer 1 chains and a Layer 2. All 3 have substantial DeFi but 2 specialize in it. Ready for this month’s picks? Let’s check them out.
Sui
We start today with Sui. In truth, Sui should not be on this list because it should not be under $1. But for the moment, it is, and you should take advantage of it at this price.
One of the cool things they have going on now is free stablecoin transfers are coming to Sui. This is on the heels of a big improvement in the tech that validators can use on Sui to save on storage and computing costs.
That’s big. This one might be even bigger. Programmable privacy is coming to Sui. Whether it’s “enterprise style privacy” like Alkimi needs with shielding but not full privacy OR real privacy in terms of access and user controls like Seal now offers within the Sui Stack, projects will be able to decide the level of privacy that works for them when building on Sui.
The Sui Stack treats this as a systems problem.
– Private execution (Nautilus)
– Scalable data (Walrus)
– Onchain verification + settlement (Sui)
– Privacy + access control (Seal)Together, these layers let Alkimi run sensitive logic, large data flows, and verifiable outcomes. pic.twitter.com/hZ0p9QxD3P

Every chain is working on how to incorporate privacy. And Sui’s solution looks like one of the best options in the market so far.
And on the DeFi end, liquidity protocol Deepbook can now support Margin Trading so the Sui apps that use Deepbook will be able to support it too. Sui is looking to build out its Hyperliquid-style perp DEX and this will go towards that.
Now, along with only Solana and EVM, Coinbase will be using the Sui token standard. This move is a big point of validation for Sui and what they are building. And it will bring them LOTS of US customers.
Excited to announce we’re partnering with @Coinbase as they adopt the Sui token standard, making it easier than ever for institutions, builders, and everyday users to participate in the Sui ecosystem. pic.twitter.com/nzPW2Pu1V1

Price Activity
As I said at the top, it’s a surprise Sui is here at this price, yet it is. Sui is currently trading at 96 cents. Its market cap is $3.6 billion, placing it at #28 in all crypto. Sui has 3.8 billion out of a total of 10 billion in circulation. This could be better. But Sui has too many things going for it as we’ve covered in many videos before like this one from about 10 days ago.
Sui just keeps building and their products work.
Canton
Canton Network is a rising star among crypto projects. Out of nowhere, it’s now the #18 project by market value.
But it didn’t happen by accident or hype. Canton is at the intersection of 2 important crypto trends. Privacy and RWA. Now you and I both know that your broker or banker can close your account and has control over your money. And we hate that and it’s one of the reasons why crypto as an industry exists today.
But banks and brokers offer one key piece the RWA market is demanding from crypto.
Not full privacy, but at least the shielding of transactions so other Morgan Stanley clients can’t see what I am buying and selling. Not to mention that Goldman or Merrill Lynch or others can’t see what I am buying and selling directly in my account.
And that level of transactional privacy is something investors and their banks both need and demand from our markets.
Canton is working on the solution. First, it’s an institutional chain and it thinks about privacy the way an investment bank would. In the same way that Ondo is working with asset issuers, Canton is working with the institutional side of RWA. The ones bringing assets to tokenize. Its goal is to bring 24/7 on-chain trading with the level of privacy that the public expects for such transactions instead of the fully open public ledgers we have now.
Their ecosystem has ETF/ETP issuers like 21Shares, crypto native funds like Arrington Capital, leading banks like Banco Santander and Bank of America, and over 200 other partners. There are also tools and infrastructure like wallets, data analysis, and 600 validators.
Canton is already doing $3 Trillion a month in repo or repurchase agreement volume, which is a clear sign of how successful the chain is so far. It also shows how much people want on-chain and privacy together.
Price Activity
Canton’s current price is 16.6c. It has all 37.6 billion $CC tokens in circulation. That gives it a market cap of $6.2 billion yet with no token unlocks to be scared of. We like that. A LOT. However, you should be aware that while the total supply is 37.6 billion and all are in circulation, the theoretical max supply is infinite. We don’t like that so much as no matter how disciplined the team is, something like Luna can happen and they will issue their token down to worthlessness. So be aware of this as it’s a clear negative on what is otherwise a project that’s found a market faster than almost any in the history of our industry.
$CC is up 40% since its TGE in November, so it’s outperforming the market in huge numbers
Mantle
Our last coin today is Mantle. Mantle is in the strong sector of DeFi and where DeFi meets TradFi.
It’s one of the most popular Layer 2s especially for DeFi and it uses ZK proofs for some privacy and to enable scaling by batching lots of transactions together. While most L2s do this, Mantle enables off-chain computation. This is a popular feature of the privacy chains and apps so this way following the entire chain of activity, like ZachXBT using block explorers, is more difficult.
In case you are curious how John Daghita (Lick) was able to steal $40M+ from US government seizure addresses.
John’s dad owns CMDSS, which currently has an active IT government contract in Virginia.

Off-chain computation is also amazing for scaling because you aren’t using blockchain resources.
Mantle’s biggest product is its institutional-grade liquid staking mETH token. The token is popular and widely used in DeFi as a way for ETH stakers to earn some extra yield by providing liquidity while staking. Typical returns on the protocol are 2.03% now but you can use mETH as collateral on many DeFi platforms for lending, borrowing or trading.
Price Activity
Mantle’s token is $MNT. $MNT is at 62.7 cents and down 47% in the last year. Sadly, that is pretty typical for most alts now with the terrible market conditions we are in. Circulating supply is 3.2 billion out of 6.2 billion, which is OK. Its market cap is just over $2 billion, placing it at #40 by market value.
It hit its ATH in October of $2.85 and has been in steep decline since. We like the project and if you can hold long term, then this is a good entry point.
