[Save this] Some of you asked me how I helped April Inch to achieve over 50k reach with one post without spending $$$. I told you I keep trying. After some thoughts, I’m thinking there must be some tips I could share. Else, I look like the “nah, I didn’t study but I scored A in the exam” student LOL

1. Close up photo
People love beautiful object, so do you. When you’re taking product photos, try some close up shots, you wouldn’t know how your followers love it.

2. Location tag
Sometimes we seem to ignore it. Instagram algorithm proves that it does help us to reach relevant audiences with location tag. Make sure you tag the right place, for example, if your target audiences are in KL, you don’t locate yourself in Penang.

3. Use A LOT OF hashtags
I pretty sure you know this, just need to make sure we use it right. Ask yourself, if you were the customers, what kind of hashtags would you type in Instagram to search for it?

4. Utilize Reels
This is one of the best features of Instagram. It opens up international market to April Inch, even though we couldn’t serve international customers, but we do gain quite a number of oversea followers. Reels is meant for short but attractive videos, try to make it within 30 seconds. Take a short clip of your BTS, how-to tutorial, the making progress, etc.

5. Use photo apps
We want everything in original, but not your photos nor videos. There was once I saw some entrepreneurs posted in FB group, 30% comes from photos, 70% comes from your editing skill XD Yes, you need great filter to make your product photos stand out. Try these easy-to-use apps: Foodie, 黄油相机 (bybutter), VCSO, Focus, Meipai

Hope this helps 🙇🏻‍♀️☺️ @ Malaysia

0. Intro

The announcement of Uniswap v3 is no doubt one of the most exciting news in the DeFi place recently 🔥🔥🔥

While most have talked about the impact v3 can potentially bring on the market, seldom explain the delicate implementation techniques to realize all those amazing features, such as concentrated liquidity, limit-order-like range orders, etc.

Since I’ve covered Uniswap v1 & v2 (if you happen to know Mandarin, here are v1 & v2), there’s no reason for me to not cover v3 as well ✅

Thus, this article aims to guide readers through Uniswap v3, based on their official whitepaper and examples made on the announcement page. However, one needs not to be an engineer, as not many codes are involved, nor a math major, as the math involved is definitely taught in your high school, to fully understand the following content 😊😊😊

If you really make it through but still don’t get shxt, feedbacks are welcomed! 🙏

There should be another article focusing on the codebase, so stay tuned and let’s get started with some background noise!

1. Uniswap & AMM recap

Before diving in, we have to first recap the uniqueness of Uniswap and compare it to traditional order book exchanges.

Uniswap v1 & v2 are a kind of AMMs (automated market marker) that follow the constant product equation x * y = k, with x & y stand for the amount of two tokens X and Y in a pool and k as a constant.

Comparing to order book exchanges, AMMs, such as the previous versions of Uniswap, offer quite a distinct user experience:

AMMs have pricing functions that offer the price for the two tokens, which make their users always price takers, while users of order book exchanges can be both makers or takers.

Uniswap as well as most AMMs have infinite liquidity¹, while order book exchanges don’t. The liquidity of Uniswap v1 & v2 is provided throughout the price range [0,∞]².

Uniswap as well as most AMMs have price slippage³ and it’s due to the pricing function, while there isn’t always price slippage on order book exchanges as long as an order is fulfilled within one tick.

In an order book, each price (whether in green or red) is a tick. Image source: https://ftx.com/trade/BTC-PERP

¹ though the price gets worse over time; AMM of constant sum such as mStable does not have infinite liquidity

² the range is in fact [-∞,∞], while a price in most cases won’t be negative

³ AMM of constant sum does not have price slippage

2. Tick

The whole innovation of Uniswap v3 starts from ticks.

For those unfamiliar with what is a tick:

Source: https://www.investopedia.com/terms/t/tick.asp

By slicing the price range [0,∞] into numerous granular ticks, trading on v3 is highly similar to trading on order book exchanges, with only three differences:

The price range of each tick is predefined by the system instead of being proposed by users.

Trades that happen within a tick still follows the pricing function of the AMM, while the equation has to be updated once the price crosses the tick.

Orders can be executed with any price within the price range, instead of being fulfilled at the same one price on order book exchanges.

With the tick design, Uniswap v3 possesses most of the merits of both AMM and an order book exchange! 💯💯💯

So, how is the price range of a tick decided?

This question is actually somewhat related to the tick explanation above: the minimum tick size for stocks trading above 1$ is one cent.

The underlying meaning of a tick size traditionally being one cent is that one cent (1% of 1$) is the basis point of price changes between ticks, ex: 1.02 — 1.01 = 0.1.

Uniswap v3 employs a similar idea: compared to the previous/next price, the price change should always be 0.01% = 1 basis point.

However, notice the difference is that in the traditional basis point, the price change is defined with subtraction, while here in Uniswap it’s division.

This is how price ranges of ticks are decided⁴:

Image source: https://uniswap.org/whitepaper-v3.pdf

With the above equation, the tick/price range can be recorded in the index form [i, i+1], instead of some crazy numbers such as 1.0001¹⁰⁰ = 1.0100496621.

As each price is the multiplication of 1.0001 of the previous price, the price change is always 1.0001 — 1 = 0.0001 = 0.01%.

For example, when i=1, p(1) = 1.0001; when i=2, p(2) = 1.00020001.

p(2) / p(1) = 1.00020001 / 1.0001 = 1.0001

See the connection between the traditional basis point 1 cent (=1% of 1$) and Uniswap v3’s basis point 0.01%?

Image source: https://tenor.com/view/coin-master-cool-gif-19748052

But sir, are prices really granular enough? There are many shitcoins with prices less than 0.000001$. Will such prices be covered as well?

Price range: max & min

To know if an extremely small price is covered or not, we have to figure out the max & min price range of v3 by looking into the spec: there is a int24 tick state variable in UniswapV3Pool.sol.

Image source: https://uniswap.org/whitepaper-v3.pdf

The reason for a signed integer int instead of an uint is that negative power represents prices less than 1 but greater than 0.

24 bits can cover the range between 1.0001 ^ (2²³ — 1) and 1.0001 ^ -(2)²³. Even Google cannot calculate such numbers, so allow me to offer smaller values to have a rough idea of the whole price range:

1.0001 ^ (2¹⁸) = 242,214,459,604.341

1.0001 ^ -(2¹⁷) = 0.000002031888943

I think it’s safe to say that with a int24 the range can cover > 99.99% of the prices of all assets in the universe 👌

⁴ For implementation concern, however, a square root is added to both sides of the equation.

How about finding out which tick does a price belong to?

Tick index from price

The answer to this question is rather easy, as we know that p(i) = 1.0001^i, simply takes a log with base 1.0001 on both sides of the equation⁴:

Image source: https://www.codecogs.com/latex/eqneditor.php

Let’s try this out, say we wanna find out the tick index of 1000000.

Image source: https://ncalculators.com/number-conversion/log-logarithm-calculator.htm

Now, 1.0001¹³⁸¹⁶² = 999,998.678087146. Voila!

⁵ This formula is also slightly modified to fit the real implementation usage.

3. Concentrated liquidity

Now that we know how ticks and price ranges are decided, let’s talk about how orders are executed in a tick, what is concentrated liquidity and how it enables v3 to compete with stablecoin-specialized DEXs (decentralized exchange), such as Curve, by improving the capital efficiency.

Concentrated liquidity means LPs (liquidity providers) can provide liquidity to any price range/tick at their wish, which causes the liquidity to be imbalanced in ticks.

As each tick has a different liquidity depth, the corresponding pricing function x * y = k also won’t be the same!

Each tick has its own liquidity depth. Image source: https://uniswap.org/blog/uniswap-v3/

Mmm… examples are always helpful for abstract descriptions 😂

Say the original pricing function is 100(x) * 1000(y) = 100000(k), with the price of X token 1000 / 100 = 10 and we’re now in the price range [9.08, 11.08].

If the liquidity of the price range [11.08, 13.08] is the same as [9.08, 11.08], we don’t have to modify the pricing function if the price goes from 10 to 11.08, which is the boundary between two ticks.

The price of X is 1052.63 / 95 = 11.08 when the equation is 1052.63 * 95 = 100000.

However, if the liquidity of the price range [11.08, 13.08] is two times that of the current range [9.08, 11.08], balances of x and y should be doubled, which makes the equation become 2105.26 * 220 = 400000, which is (1052.63 * 2) * (110 * 2) = (100000 * 2 * 2).

We can observe the following two points from the above example:

Trades always follow the pricing function x * y = k, while once the price crosses the current price range/tick, the liquidity/equation has to be updated.

√(x * y) = √k = L is how we represent the liquidity, as I say the liquidity of x * y = 400000 is two times the liquidity of x * y = 100000, as √(400000 / 100000) = 2.

What’s more, compared to liquidity on v1 & v2 is always spread across [0,∞], liquidity on v3 can be concentrated within certain price ranges and thus results in higher capital efficiency from traders’ swapping fees!

Let’s say if I provide liquidity in the range [1200, 2800], the capital efficiency will then be 4.24x higher than v2 with the range [0,∞] 😮😮😮 There’s a capital efficiency comparison calculator, make sure to try it out!

Image source: https://uniswap.org/blog/uniswap-v3/

It’s worth noticing that the concept of concentrated liquidity was proposed and already implemented by Kyper, prior to Uniswap, which is called Automated Price Reserve in their case.⁵

⁶ Thanks to Yenwen Feng for the information.

4. Range orders: reversible limit orders

As explained in the above section, LPs of v3 can provide liquidity to any price range/tick at their wish. Depending on the current price and the targeted price range, there are three scenarios:

current price < the targeted price range

current price > the targeted price range

current price belongs to the targeted price range

The first two scenarios are called range orders. They have unique characteristics and are essentially fee-earning reversible limit orders, which will be explained later.

The last case is the exact same liquidity providing mechanism as the previous versions: LPs provide liquidity in both tokens of the same value (= amount * price).

There’s also an identical product to the case: grid trading, a very powerful investment tool for a time of consolidation. Dunno what’s grid trading? Check out Binance’s explanation on this, as this topic won’t be covered!

In fact, LPs of Uniswap v1 & v2 are grid trading with a range of [0,∞] and the entry price as the baseline.

Range orders

To understand range orders, we’d have to first revisit how price is discovered on Uniswap with the equation x * y = k, for x & y stand for the amount of two tokens X and Y and k as a constant.

The price of X compared to Y is y / x, which means how many Y one can get for 1 unit of X, and vice versa the price of Y compared to X is x / y.

For the price of X to go up, y has to increase and x decrease.

With this pricing mechanism in mind, it’s example time!

Say an LP plans to place liquidity in the price range [15.625, 17.313], higher than the current price of X 10, when 100(x) * 1000(y) = 100000(k).

The price of X is 1250 / 80 = 15.625 when the equation is 80 * 1250 = 100000.

The price of X is 1315.789 / 76 = 17.313 when the equation is 76 * 1315.789 = 100000.

If now the price of X reaches 15.625, the only way for the price of X to go even higher is to further increase y and decrease x, which means exchanging a certain amount of X for Y.

Thus, to provide liquidity in the range [15.625, 17.313], an LP needs only to prepare 80 — 76 = 4 of X. If the price exceeds 17.313, all 4 X of the LP is swapped into 1315.789 — 1250 = 65.798 Y, and then the LP has nothing more to do with the pool, as his/her liquidity is drained.

What if the price stays in the range? It’s exactly what LPs would love to see, as they can earn swapping fees for all transactions in the range! Also, the balance of X will swing between [76, 80] and the balance of Y between [1250, 1315.789].

This might not be obvious, but the example above shows an interesting insight: if the liquidity of one token is provided, only when the token becomes more valuable will it be exchanged for the less valuable one.

…wut? 🤔

Remember that if 4 X is provided within [15.625, 17.313], only when the price of X goes up from 15.625 to 17.313 is 4 X gradually swapped into Y, the less valuable one!

What if the price of X drops back immediately after reaching 17.313? As X becomes less valuable, others are going to exchange Y for X.

The below image illustrates the scenario of DAI/USDC pair with a price range of [1.001, 1.002] well: the pool is always composed entirely of one token on both sides of the tick, while in the middle 1.001499⁶ is of both tokens.

Image source: https://uniswap.org/blog/uniswap-v3/

Similarly, to provide liquidity in a price range < current price, an LP has to prepare a certain amount of Y for others to exchange Y for X within the range.

To wrap up such an interesting feature, we know that:

Only one token is required for range orders.

Only when the current price is within the range of the range order can LP earn trading fees. This is the main reason why most people believe LPs of v3 have to monitor the price more actively to maximize their income, which also means that LPs of v3 have become arbitrageurs 🤯

I will be discussing more the impacts of v3 in 5. Impacts of v3.

⁷ 1.001499988 = √(1.0001 * 1.0002) is the geometric mean of 1.0001 and 1.0002. The implication is that the geometric mean of two prices is the average execution price within the range of the two prices.

Reversible limit orders

As the example in the last section demonstrates, if there is 4 X in range [15.625, 17.313], the 4 X will be completely converted into 65.798 Y when the price goes over 17.313.

We all know that a price can stay in a wide range such as [10, 11] for quite some time, while it’s unlikely so in a narrow range such as [15.625, 15.626].

Thus, if an LP provides liquidity in [15.625, 15.626], we can expect that once the price of X goes over 15.625 and immediately also 15.626, and does not drop back, all X are then forever converted into Y.

The concept of having a targeted price and the order will be executed after the price is crossed is exactly the concept of limit orders! The only difference is that if the range of a range order is not narrow enough, it’s highly possible that the conversion of tokens will be reverted once the price falls back to the range.

As price ranges follow the equation p(i) = 1.0001 ^ i, the range can be quite narrow and a range order can thus effectively serve as a limit order:

When i = 27490, 1.0001²⁷⁴⁹⁰ = 15.6248.⁸

When i = 27491, 1.0001²⁷⁴⁹¹ = 15.6264.⁸

A range of 0.0016 is not THAT narrow but can certainly satisfy most limit order use cases!

⁸ As mentioned previously in note #4, there is a square root in the equation of the price and index, thus the numbers here are for explantion only.

5. Impacts of v3

Higher capital efficiency, LPs become arbitrageurs… as v3 has made tons of radical changes, I’d like to summarize my personal takes of the impacts of v3:

Higher capital efficiency makes one of the most frequently considered indices in DeFi: TVL, total value locked, becomes less meaningful, as 1$ on Uniswap v3 might have the same effect as 100$ or even 2000$ on v2.

The ease of spot exchanging between spot exchanges used to be a huge advantage of spot markets over derivative markets. As LPs will take up the role of arbitrageurs and arbitraging is more likely to happen on v3 itself other than between DEXs, this gap is narrowed … to what extent? No idea though.

LP strategies and the aggregation of NFT of Uniswap v3 liquidity token are becoming the blue ocean for new DeFi startups: see Visor and Lixir. In fact, this might be the turning point for both DeFi and NFT: the two main reasons of blockchain going mainstream now come to the alignment of interest: solving the $$ problem 😏😏😏

In the right venue, which means a place where transaction fees are low enough, such as Optimism, we might see Algo trading firms coming in to share the market of designing LP strategies on Uniswap v3, as I believe Algo trading is way stronger than on-chain strategies or DAO voting to add liquidity that sort of thing.

After reading this article by Parsec.finance: The Dex to Rule Them All, I cannot help but wonder: maybe there is going to be centralized crypto exchanges adopting v3’s approach. The reason is that since orders of LPs in the same tick are executed pro-rata, the endless front-running speeding-competition issue in the Algo trading world, to some degree, is… solved? 🤔

Anyway, personal opinions can be biased and seriously wrong 🙈 I’m merely throwing out a sprat to catch a whale. Having a different voice? Leave your comment down below!

6. Conclusion

That was kinda tough, isn’t it? Glad you make it through here 🥂🥂🥂

There are actually many more details and also a huge section of Oracle yet to be covered. However, since this article is more about features and targeting normal DeFi users, I’ll leave those to the next one; hope there is one 😅

If you have any doubt or find any mistake, please feel free to reach out to me and I’d try to reply AFAP!

Stay tuned and in the meantime let’s wait and see how Uniswap v3 is again pioneering the innovation of DeFi 🌟

Uniswap v3 Features Explained in Depth was originally published in Taipei Ethereum Meetup on Medium, where people are continuing the conversation by highlighting and responding to this story.

👏 歡迎轉載分享鼓掌

Let me get this straight. As a close participant of last year’s movement, I fully support all forms of sanctions over Hong Kong by the international community, whether it is to cancel our privileged economic status or re-consider all aspects of Hong Kong as a separate custom territory from China.

The reason is simple: by announcing the new national security law over Hong Kong, China’s CCP has spelled the end of “one country, two systems” and shattered any hopes on finding democracy in Hong Kong. If CCP is ready to ruin Hong Kong politically, then they must also bear the risk of Hong Kong losing all of its previous privileges, such as Hong Kong’s status as a key global financial center - which was only there in the first place because of Hong Kong’s high degree of autonomy and rule of law.

It baffles me when Hong Kong’s pro-democracy politicians are asking for otherwise. In an article in New York Times, Jimmy Lai, owner of Apple Daily (aka the only opposition newspaper left in HK), asked the US government not to completely remove Hong Kong’s special status. He claimed that such action will make Hong Kong more dependent on China. Meanwhile, other pro-democracy political leaders kept telling foreign press the need to maintain HK’s special status. It might sound comforting at first, but such narrative completely contradicts what Hong Kong people have been through in the last year or so.

When we say “if we burn, you burn with us” on the street, it means exactly that – Hong Kong has been waiting for democracy since 1997, it was promised to us and written in the Basic Law. Almost half of fifty years were gone and we are still seeing ZERO signs of real democracy. We have had our peaceful protests over the years – last June we have had 2 millions people demonstrating on the street peacefully demanding for universal suffrage – and mind you Hong Kong only has a population of 7.5 millions. So when we said such words, it means that we were ready to escalate the level of protest in demand for democracy.

For us, it was of course a means to an end – the means being to demonstrate a strong stance for CCP that we are ready to sacrifice all of Hong Kong if CCP is unable to fulfill their promise. The end being achieving real democracy. The onus was always on Beijing to fulfill their promise and move towards a better future for Hong Kong. Since last year, we have had many sacrifices fighting this battle. Many young people have risked their lives and future fighting for freedom. I myself for one is under trial for riot and I’m not afraid if that’s what it takes.

When our government and CCP decided oppression is the way out, the onus is not on us to beg for mercy. In fact, I am glad that the international community is finally taking action against such oppression and imposing sanctions over Hong Kong. By oppressing Hong Kong in such manner, Beijing simply does not deserve Hong Kong anymore – whether using it as a financial hub, a trade hub, it’s unique currency and equity…etc. You may call it a showdown – if Hong Kong means nothing to China economically, then we loses out on everything – but we have already lost so much to back down at this point. Also from the very beginning, this is the bet we were willing to take, hence the slogan. However, if Hong Kong really is that special, then getting rid of its special status will hurt China fundamentally. There’s simply no future for Hong Kong if CCP and its ideologies continue to dominate.

I want to make sure everyone knows that there’s no fairy tales in Hong Kong anymore. If Hong Kong continues to prosper despite what Beijing had done to it, then it’s the biggest joke to human rights and all that I have learnt about democracy in the last twenty-six years. In our battle against China’s authoritarian regime, Hong Kong people will stand strong and unite as one.

I am glad that the U.S. is ending its special relationship with Hong Kong, and I hope that other countries such as Australia, Britain, Canada, the EU and others will soon follow to impose further sanctions over Hong Kong.

What are Yamaha Motor Co., Ltd. and V-MAX (buoy max)?
It is one of the large-scale automatic operation two-wheeled vehicles from which export is begun in 1985 from YAMAHA MOTOR to foreign countries. It was being sold by Japan for a certain period of time.
The formal nomenclature is Vmax. It was sold by the name of Vmax12 in the United States. The body type is a naked type, is an American type, and is peculiar, that it is not possible to take it. Installed engines are four type cylinders 1,200cc of four water-cooled strokes V. The design that is reminiscent of the game vehicle in which it participates in a drag racing that competes for the speed in the start acceleration from 0mph and American motor sports causes the charm of one's own. The accelerating force was said at the announcement this time that it surpassed Porsche, and the arrival time to distance 0?1/4 mile of the drag racing (about 402m) boasted of the ability that reached the stand for ten seconds. The deep-rooted popularity is kept in the large-scale motorcycle market in Japan though 20 years or more have already passed from the sale. Moreover, an original design of dummy became popular as for the fuel tank (The real thing was the seat under) and the air duct, too.
V boost system

Maximum this feature in the vehicle was to have installed the device that was called V boost system. It is a mechanism that the butterfly valve that ties from the vicinity where engine revolutions exceeded 6,000 rotations before and behind the intake manifold under the carburetor begins to open, it becomes opening completely in 8,500 rotations, it changes into twin pots a cylinder (state that two carburetors are connected), the state to have installed the big diameter carburetor only when rotating high is produced, and a large amount of air-fuel mixture is introduced aggressively in the cylinder. Actually, it was the one it was possible to blow strongly the sudden change for every 6,500 rotations enough to actually feel 145ps that was the world's largest car of mass-producing on the market at that time output. However, the adoption was put off by the body of the domestic specification put on the market back because of the horsepower restriction. However, parts of the relation were sold to V boost like the kit that installed V boost in a domestic specification with the back and the full-time V boost system, etc. , and finishing up a domestic specification more than an overseas specification became possible.
Anecdote

...United States.. ..".. thing of having answered promptly," compared with the question that the engineer of the own country (Japan) it when Vmax is made says to the United States, "When making it, does it only have to be made the output of which extent a standard?" is a famous story.

If first target time of 0-1/4 miles cannot be achieved because it became too heavy too much while producing it, the designer : , saying that "Is 'Parts of the engine' and is there a motorcycle about plastic?" as soon as it takes and he or she starts making the air scoop made of the nonmetal because the engineer of Yamaha Motor Co., Ltd. that has misgivings is a dummy anyway because he or she got angry. Most of the body exterior except the fender etc. are composed of the Cromori steel or aluminum (Of course, the time of the target is cleared).

The anecdote that the insurance of so-called "Macho motorcycle" of the Vmax type soars remains in North America after that because the photograph of the burnout of opening wide that extends to the demonstration of the burnout by the Yamaha Motor Co., Ltd. works rider of WGP and Kenny Roberts and the founder catalogs by two pages was too sensational when the debut is announced.
