✅OVERALL RATING: 10/10
🔴MY REVIEW: I like the brand PANDORA derived from the brand's positioning as an "affordable luxury brand". The original intention of this brand was to encourage girls to be themselves and show their true self in their own way. How interesting! The advantage of PANDORA is that you can buy it according to your own budget. Even if you only buy a necklace, you can wear it with a simple and elegant unique style. Another special feature of PANDORA is that each bracelet can be matched and interchanged with a variety of gold or silver charms. Everyone's collocation is unique. Speaking of my favorite, it is none other than the Pandora Moments Snake Chain Bracelet. The material is soft and fits the curvature of the wrist better. It is also one of the most classic styles in the brand. I especially like PANDORA charms. Each charm represents a memory and has a special meaning. And you can mix and match according to your own preferences. In my opinion, Pandora is a very story-telling brand, allowing consumers to wear a unique bracelet based on their imagination, and let the bracelet tell our own story. What an incredible thing this is.

📌Disclaimer: The above review is purely personal opinion. Not everyone likes what I like. Please note that what may work for me, may not work for anyone else. Results may vary from person to person, so please take this into consideration if you decide to try those products.

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

Recently I’ve seen many rumors circulating about me and enormous amounts of hate. This is no surprise to me. I know that since most people are not aware of the full meaning of the climate crisis (which is understandable since it has never been treated as a crisis) a school strike for the climate would seem very strange to people in general.
So let me make some things clear about my school strike.

In may 2018 I was one of the winners in a writing competition about the environment held by Svenska Dagbladet, a Swedish newspaper. I got my article published and some people contacted me, among others was Bo Thorén from Fossil Free Dalsland. He had some kind of group with people, especially youth, who wanted to do something about the climate crisis.
I had a few phone meetings with other activists. The purpose was to come up with ideas of new projects that would bring attention to the climate crisis. Bo had a few ideas of things we could do. Everything from marches to a loose idea of some kind of a school strike (that school children would do something on the schoolyards or in the classrooms). That idea was inspired by the Parkland Students, who had refused to go to school after the school shootings.
I liked the idea of a school strike. So I developed that idea and tried to get the other young people to join me, but no one was really interested. They thought that a Swedish version of the Zero Hour march was going to have a bigger impact. So I went on planning the school strike all by myself and after that I didn’t participate in any more meetings.

When I told my parents about my plans they weren’t very fond of it. They did not support the idea of school striking and they said that if I were to do this I would have to do it completely by myself and with no support from them.
On the 20 of august I sat down outside the Swedish Parliament. I handed out fliers with a long list of facts about the climate crisis and explanations on why I was striking. The first thing I did was to post on Twitter and Instagram what I was doing and it soon went viral. Then journalists and newspapers started to come. A Swedish entrepreneur and business man active in the climate movement, Ingmar Rentzhog, was among the first to arrive. He spoke with me and took pictures that he posted on Facebook. That was the first time I had ever met or spoken with him. I had not communicated or encountered with him ever before.

Many people love to spread rumors saying that I have people ”behind me” or that I’m being ”paid” or ”used” to do what I’m doing. But there is no one ”behind” me except for myself. My parents were as far from climate activists as possible before I made them aware of the situation.
I am not part of any organization. I sometimes support and cooperate with several NGOs that work with the climate and environment. But I am absolutely independent and I only represent myself. And I do what I do completely for free, I have not received any money or any promise of future payments in any form at all. And nor has anyone linked to me or my family done so.
And of course it will stay this way. I have not met one single climate activist who is fighting for the climate for money. That idea is completely absurd.
Furthermore I only travel with permission from my school and my parents pay for tickets and accommodations.

My family has written a book together about our family and how me and my sister Beata have influenced my parents way of thinking and seeing the world, especially when it comes to the climate. And about our diagnoses.
That book was due to be released in May. But since there was a major disagreement with the book company, we ended up changing to a new publisher and so the book was released in august instead.
Before the book was released my parents made it clear that their possible profits from the book ”Scener ur hjärtat” will be going to 8 different charities working with environment, children with diagnoses and animal rights.

And yes, I write my own speeches. But since I know that what I say is going to reach many, many people I often ask for input. I also have a few scientists that I frequently ask for help on how to express certain complicated matters. I want everything to be absolutely correct so that I don’t spread incorrect facts, or things that can be misunderstood.

Some people mock me for my diagnosis. But Asperger is not a disease, it’s a gift. People also say that since I have Asperger I couldn’t possibly have put myself in this position. But that’s exactly why I did this. Because if I would have been ”normal” and social I would have organized myself in an organisation, or started an organisation by myself. But since I am not that good at socializing I did this instead. I was so frustrated that nothing was being done about the climate crisis and I felt like I had to do something, anything. And sometimes NOT doing things - like just sitting down outside the parliament - speaks much louder than doing things. Just like a whisper sometimes is louder than shouting.

Also there is one complaint that I ”sound and write like an adult”. And to that I can only say; don’t you think that a 16-year old can speak for herself? There’s also some people who say that I oversimplify things. For example when I say that "the climate crisis is a black and white issue”, ”we need to stop the emissions of greenhouse gases” and ”I want you to panic”. But that I only say because it’s true. Yes, the climate crisis is the most complex issue that we have ever faced and it’s going to take everything from our part to ”stop it”. But the solution is black and white; we need to stop the emissions of greenhouse gases.
Because either we limit the warming to 1,5 degrees C over pre industrial levels, or we don’t. Either we reach a tipping point where we start a chain reaction with events way beyond human control, or we don’t. Either we go on as a civilization, or we don’t. There are no gray areas when it comes to survival.
And when I say that I want you to panic I mean that we need to treat the crisis as a crisis. When your house is on fire you don’t sit down and talk about how nice you can rebuild it once you put out the fire. If your house is on fire you run outside and make sure that everyone is out while you call the fire department. That requires some level of panic.

There is one other argument that I can’t do anything about. And that is the fact that I’m ”just a child and we shouldn’t be listening to children.” But that is easily fixed - just start to listen to the rock solid science instead. Because if everyone listened to the scientists and the facts that I constantly refer to - then no one would have to listen to me or any of the other hundreds of thousands of school children on strike for the climate across the world. Then we could all go back to school.
I am just a messenger, and yet I get all this hate. I am not saying anything new, I am just saying what scientists have repeatedly said for decades. And I agree with you, I’m too young to do this. We children shouldn’t have to do this. But since almost no one is doing anything, and our very future is at risk, we feel like we have to continue.


And if you have any other concern or doubt about me, then you can listen to my TED talk ( https://www.ted.com/…/greta_thunberg_the_disarming_…/up-next ), in which I talk about how my interest for the climate and environment began.

And thank you everyone for you kind support! It brings me hope.

Ps I was briefly a youth advisor for the board of the non profit foundation “We don’t have time”. It turns out they used my name as part of another branch of their organisation that is a start up business. They have admitted clearly that they did so without the knowledge of me or my family. I no longer have any connection to “We don’t have time”. Nor has anyone in my family. They have deeply apologised and I have accepted their apology.
