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 🌟

กลับมาลือกันอีกครั้งสำหรับความคืบหน้าของเกม Remastered ที่หลายคนน่าจะรอคอยกันอยู่อย่าง Mass Effect Remastered ที่มีข่าวลือออกมามากมายในช่วงที่ผ่านมา แต่ในคราวนี้ดูเหมือนจะเป็นข่าวที่ไม่สู้ดีนัก เพราะตัวเกมอาจใช้เวลาในการพัฒนาที่นานกว่าที่คาดเอาไว้
.
ข้อมูลนี้มาจากคุณ Jeff Grub นักเขียนของเว็บไซต์ VentureBeat ที่อ้างถึงแหล่งข้อมูลของเขาที่ใกล้ชิดกับทาง EA และ Bioware ว่า เราน่าจะไม่ได้เห็นเกม Mass Effect ฉบับ Remastered ออกวางจำหน่ายในปีนี้อย่างแน่นอน เนื่องจากการแพร่ระบาดของไวรัส COVID-19 นั้นทำให้งานทุกอย่างนั้นล่าช้าไปหมด รวมไปถึงตัวเกมในภาคแรกนั้นยังมีคุณภาพที่ "ยังไม่ดีพอ" เมื่อเทียบกับคุณภาพของเกมสองภาคที่เหลือ
.
"ตัวแปรสำคัญอีกอย่างหนึ่งนอกจาเรื่องโรคระบาดก็คือตัวเกมภาคแรกแบบต้นฉบับ ที่มีคุณภาพไม่ได้ใกล้เคียงกับเกมอื่นที่เหลืออยู่เลยแม้แต่น้อย" Grub กล่าว "มันจะทำให้เกิดความรู้สึกแง่ลบต่อผู้เล่นใหม่ และอาจทำให้หลายคนไม่รู้สึกอยากไปเล่นเกมภาคต่อไปได้เลย"
.
Grub ยังกล่าวเพิ่มอีกว่า ปัญหาใหญ่ที่สุดของเรื่องนี้ก็คือเรื่องของ Gameplay และงานภาพต่าง ๆ ที่ล้าสมัยอย่างมาก เพราะ Mass Effect ภาคแรกนั้นวางจำหน่ายในปี 2007 ก็เลยอาจทำให้ผู้เล่นในยุคนี้ไม่รู้สึกประทับใจอีกต่อไปแล้วนั่นเอง
.
"ทีมงานที่รับผิดชอบเข้าใจเป็นอย่างดีถึงปัญหานี้ และพวกเขาอยากจะเปลี่ยนแปลงมันให้ถูกต้องเพื่อแฟน ๆ "
.
แน่นอนว่าในเวลานี้ Mass Effect Remastered นั้นจะยังไม่มีการประกาศเปิดตัว แต่จากข่าวที่หลุดออกมาอย่างต่อเนื่องก็น่าจะทำให้เราเชื่อได้ว่ามันมีอยู่จริง และเราก็น่าจะยังไม่ได้สัมผัสมันในปีนี้ ซึ่งหลายคนคาดว่าอย่างเร็วที่สุดที่เราจะได้เห็นมัน ก็คงเป็นช่วงต้นปีหน้า ส่วนจะเป็นอย่างนั้นหรือไม่นั้น ก็ต้องมารอดูกันต่อไป

#ข่าวเกม #gamingdose #MassEffectRemastered
Rumor again for the progress of the Remastered game that many people should have been waiting for. Mass Effect Remastered with many rumors in the past. But this time, it seems like a bad news. The game may take a long time to develop a better place than expected.
.
This information is from Mr Jeff Grub, the writer of VentureBeat website who referred to his resources close to EA and Bioware that we probably wouldn't have seen the Mass Effect remastered game released this year for sure due to the COVID-19 virus epidemic. Every work is delayed. Including the game in the first part, there is a quality ′′ not good enough ′′ compared to the quality of the remaining two-part games.
.
′′ Another important variable, besides the plague, is the first part of the quality, first part game. Not even close to the remaining games Grub says It will cause negativity to new players and may cause many people not. Feel like playing the next game ′′
.
Grub also adds that the biggest issue of this is Gameplay and graphic work that is highly outdated because Mass Effect first episode is released in 2007, so it may not be impressed by the players in this era. It's next.
.
′′ Responsible teamwork understands this problem and they want to change it right for the fans
.
Surely at this time, Mass Effect Remastered is still unveiling, but from the ongoing leaking news it exists, and we probably haven't experienced it yet this year, which many people guess as soon as we can see. It will be early next year. Either that or it will be. Let's wait and see.

CBR1100XX SuperBlackbird (Shebearl Dableccssuparbraccbard) is a motorcycle of four strokes and displacements 1,137cc that Honda Motor Co., Ltd. was manufacturing. Both domestic sales and export have ended now though it was treated as a flagship in the CBR series. Outline

Honda Motor Co., Ltd. appears in restyling from CBR1000F in 1996. In that case, a pet name "Super-blackbird" was given in the meaning said that was connected to "Blackbird" that was the pet name of surveillance plane "SR-71" of an American air force that was the aircraft at the velocity of the world, and it exceeded. Therefore, the cooperation of the U.S. Air Force is received in the pop promo of this car, and CBR1100XX and SR-71 accomplish competing in the air base.

As a concept

1. Comfortable livability in super-high-speed region
2. Overwhelming absolute performance
3. The middle class level is handled though it is a large displacement car.

It was a car of mass-producing on the market of the world best performance
where was had both.

Four 1137cc water-cooled series cylinder engine of the new design that adopts two axis balancer achieves the highest 164ps in the world at that time. Maximum speed is one that doesn't come up slightly by actual measurement at 300 km/h though excelled from ZZR1100 of Kawasaki who was the rival at the development this time to a high-speed performance.

It comes to transfer the seat at the velocity of the world from Kawasaki by the appearance of ninja ZX-12R the GSX1300R falcon's appearing from the sea bass in 1999, and continuously while leaving the name of the car of mass-producing on the market at the velocity of the world wanted in 2000 at the sale this time. The self-imposed restraint of which 300 km/h is a maximum speed upper bound of the motorcycle in 2001 has started, a big restyling is not done to the production stoppage in 2007, and the character as Haispedotsarar has become strong. Moreover, it is used as a development vehicle of VCM (Variable Cylinder Management: cylinder stop system) that is next generation's fuel fuel cost improvement technology, and 2 in the magazine medium from which impression is open to the public.

It is a motorcycle that Isao Yamanaka who had invented a lot of great cars as an engineer of HONDA developed at the end, and 3 said, "It is a compilation to invest everything current, and the happiest motorcycle".
The headlight of the top and bottom two step is adopted for the full caul body that thoroughly pursued aerodynamic. The synchronization brake is equipped normally before and after being called D-CBS. For the tone of red to lighten in 1998, and to prevent over cool in the cold district, the by-pass of Rageetar was added. Even the model is a carburetor specification in 1998, and it is a model to whom the chalk is only attached in CBR1100XX. The accelerating force and the response are sharper than the injection model since the second generation though a maximum speed region doesn't change. In the founder blackbird, as a motorcycle of the carburetor specification, on the market, acceleration and maximum speed are the fastest models. Low-speed..gear..Red Zone..blow..at the same time as..accelerating force..further..increase..power..band..use regularly..user..partially..core..acceleration..mania..rocket engine..missile..acceleration..criticize.Not a rapid response like the carburetor specification but the getting on taste has smoothed very much though this characteristic has been succeeded since the second generation made FI.

The direct air intake (ram air) has not taken side with the founder. The inspiratory port where the wire net under the headlight attached sends oil cooler the running style though it often makes a mistake. Because the cold wind doesn't hit oil cooler as it is because oil cooler has adhered behind the radiator, the inflow road of air is installed in this manner.
