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 🌟

[專頁公告] 英文學習「生態系」更新
English Learning Ecosystem Update
As I began exploring Instagram, I struggled to find a way to deliver useful academic content. Instagram posts typically focus on images, short clips, and concise text, which are attention grabbing but not always entirely conducive to language learning. I looked over the posts of established Instagram English learning accounts, and experimented with vocabulary posts and even news posts for a couple of weeks. Not wanting to post just images, I thought about creating something new even with the rigid format of the platform.
當我開始研究怎麼用IG,我想盡了各種辦法,希望能提供大家一些實用的學術內容。 IG 的特色著重在圖片、短片以及簡潔的文字,這樣的方式雖然很容易引人注目,卻不全然有助於語言學習。我瀏覽了 IG 上英文教學網紅的貼文,並在這幾週嘗試發了一些學術單字與新聞相關的文章。我並不想只是發一些圖片,而思考著要如何在既有框架下創作一些新的東西。
★★★★★★★★★★★★
A tenet of using tech in education is to engage students with what they are familiar with, not give them an entirely new platform that is difficult to use. So, how could I create a new series of Instagram posts that is both educational and unique? I thought about my goal to disseminate academic English resources, and how I could leverage my experience as a curriculum writer and voice recording artist for public school textbooks.
一個使用科技進行教育的原則是用學生熟悉的方式與他們互動,而非用了全新的平台卻使他們難以學習。那麼,我應該如何創作獨特且具教育意義的一系列全新 IG 發文呢?我想到了我傳遞學術英文資源的目標,以及思考到該如何發揮身為教科書編輯者與音頻錄製者的經驗。
★★★★★★★★★★★★
So far, this is what I have at the moment. I will post Word of the Day (每日一詞), high frequency vocabulary words that you see in academic texts and sometimes on the news. These Tier 2 academic vocabulary words are not exclusive to a single domain and complement the theme-based approach I’ve taken with my mind-mapping vocabulary class. You can find other vocabulary learning methods here.
這是我目前所想到的內容:我會發布「每日一詞」,也就是學術文章或是新聞中有時出現的高頻字彙。這些Tier 2學術詞彙並不限於單個領域,更補充了我在心智圖詞彙攻略課程中採用的主題式學習法。你還可以在下面網站找到其他詞彙學習方法。
🎓 詞彙學習方法:http://bit.ly/2JGXKvK
In these posts, I added the pronunciation, collocation, and example sentences of each word for students. These words will be helpful to university-level students who often read academic texts and the news. Students can access them by simply clicking on the hashtag 學術英語單字.
在這些貼文中,我為學生提供了發音、搭配用法和例句。這些單字會對經常閱讀學術文章和新聞的大學程度學生有所幫助。學生只要點貼文上的#學術英語單字即可看到貼文。
🎓 學術英文單字: https://bit.ly/3cxH091
★★★★★★★★★★★★
To help students use more precise and common academic phrases, I then added Academic Phrases (每日一句), set phrases that appear in both academic speech and writing. These phrases have varying functions from introducing a topic to comparing and contrasting ideas. There is a difference between speech and writing, so I picked words that could be used for both. If one is used only in a specific context, I will make note of it in the video recording. This series of posts will help students with language output, and can be found under the following hashtag 學術英語片語.
為了幫助學生使用更精準、更道地的常見學術用語,我們接著會進入「每日一句」,也就是在學術演說與寫作中常見的用語。這些片語具有不同的功能,範圍涵蓋介紹主題到比較、對比想法等等。而演講和寫作之間也有不同,所以我選擇了都可以使用的片語。如果只能在特定情況下使用,我會在影片中特別說明。該系列文章將會幫助學生提高語言輸出能力,可以在 # 學術英語片語找到。
🎓 學術英文片語: https://bit.ly/3aqaQcP
★★★★★★★★★★★★
Last, I will follow up with an abridged version of breaking news (時事英文) with high frequency collocations and audio recordings. This will provide students with the input of not only individual words, but how to use them in output (speech and writing) with context. While all these news posts might seem independent at first, I will eventually link and organize them by theme when there are enough posts. Along with my news class, these extra posts will help students stay aware of current events, acquire set phrases used in journalism, and develop critical thinking. These posts can currently be found under the hashtag EEL時事英文.
最後,我們會跟進精簡版的「時事英文」,其中包含高頻搭配詞與錄音資料。這些內容不僅可以提供你們輸入單字,而且可以幫助你們知道如何搭配情境輸出,再將這些內容使用在口說與寫作中。這些貼文一開始雖然看似獨立,當素材足夠後我會再將他們進行連結與整理。這些貼文和我的新聞課程將幫助學生維持對時事的敏銳度,掌握新聞中使用的固定用法,並養成批判性思維。這些貼文目前可以在 # EEL時事英文。

one note教學 在 [WP8 ] OneNote 超好用之小小教學文- 看板WindowsPhone 的推薦與評價
已經是OneNote高手的各位可以直接跳過這篇了Orz
這篇是留給還沒搞懂如何操作 電腦-手機 兩端同步的人
首先電腦端需求軟體為 Office2010以上,或者直接在網頁上用線上app操作
手機端則是WP8內建Onenote
手機與電腦兩端都裝上SkyDrive app
然後在電腦端打開OneNote軟體
點選左上角 "檔案"
往下拉有個 "共用" 選項,點選進入之後
選擇 2.在以下位置共用 選擇(Web)
之後選擇Web 位置,沒意外就是你的SkyDrive位置
3. 選擇要用的共用資料夾或者自行新創一個放筆記本的資料夾
選好之後
點選右下角的 "共用筆記本"
接著skydrive上以及手機端就可以看到並開啟或編輯這個新建立的筆記本
此時這個筆記本的存放位置就是在skydrive上
但是到這裡仍然還不能在電腦上直接閱讀與編修手機端的OneNote檔案
一開始內建的有 "家庭俱樂部" 與 "快速筆記"
值得一提的是家庭俱樂部的權限是開放給選定的人一同編輯
快速筆記則只有開放給個人
要能進行編輯一樣要選擇左上角的 "檔案"
往下拉點選 "開啟舊檔"
然後直接去讀 Skydrive的資料夾內的檔案
例如家庭俱樂部資料夾內會有個家庭俱樂部檔案
(用app資料夾看是一個小地球標籤的檔案)
快速筆記則是放在Documents資料夾內
(一樣是個人快速筆記名稱+地球標籤的檔案)
用打開舊檔的方式打開之後
就可以在電腦端與手機端同步來共同使用
這方法也可以邀請其他人員加入
而且這樣就可以在電腦端自行編修手機端的筆記章節或頁面名稱
此外
手機裡記錄的onenote頁面只能直直往下編輯內容
電腦端的頁面限制少很多,可以橫向增加內容
我剛剛嘗試用電腦端在手機頁面寫好的購物清單裡增加內容
然後是故意在原本頁面的橫向區域增加新內容
兩端同步之後
手機端的頁面也跟著變大可以在旁邊增加內容
可是刪除該內容之後
手機端的頁面又變成一條直行可編寫內容無法往橫向發展

我昨天就是有些沒同步完成之後就離開導致有死檔
為了刪除又是搞半天
然後一開始沒想好檔案名稱
事後要改又很難改...
總結來說
一開始要想好主機端要設立在哪裡
從主機端開啟分享共用給其他好幾的子端
然後統一由主機端來管理會比較方便些
PS.
剛剛我太太要我把前幾天挑的幾款電冰箱的資訊目錄給他拿賣場比價
小的立刻就用OneNote 家庭俱樂部共用端 在電腦上編輯好頁面就投過去
對方立刻就能一目瞭然
一整個方便!!!
