Decentralized exchanges are nonetheless rife with numerous imperfections together with slippage and impermanent loss.
Chinese language crypto undertaking DODO hopes to resolve a few of these shortcomings with its novel “Proactive Market Maker” algorithm.
The platform is nascent, and has but to show the take a look at of time like incumbents Uniswap and Curve.

Although there are various decentralized exchanges (DEXes) that merchants can select from as of late, few have been as dominant as Uniswap. Nonetheless, the unicorn crypto platform is way from good.
DODO Change, a brand new arrival to the DEX enviornment, hopes to seize market share by enhancing on Uniswap’s imperfections. How?
By a novel market-making algorithm that improves liquidity and makes an attempt to get rid of impermanent loss.
Getting Began with Decentralized Exchanges
The first comparability used all through this information might be that of Uniswap. Different related DEXes embrace Bancor, Curve, Kyber, and Balancer.
The favored DeFi buying and selling platform affords a base understanding for automated market making (AMMs), the shortfalls of this design, impermanent loss, slippage, and the position of arbitrageurs in a decentralized setting. DODO, and its rivals, is juggling the identical constellation of concepts.
AMMs differ from centralized exchanges in the way in which that they worth tokens. As a substitute of discovering a counterparty to purchase or promote an asset, and thus set up a worth, the counterparty is changed by a pool of tokens saved on a sensible contract. And in contrast to centralized exchanges, liquidity for these swimming pools is supplied by customers.
These customers are incentivized to supply liquidity by incomes returns on the belongings they supply. The present buying and selling charge on Uniswap is 0.30%, and this charge is distributed amongst all liquidity suppliers (LPs) for serving to maintain the platform.
Platforms like Uniswap additionally differ in the way in which that they worth the belongings listed. For the sake of precision, it ought to be mentioned that there are various sorts of AMMs. Uniswap leverages a range referred to as “Fixed Product Market Maker.” DODO makes use of one other selection referred to as “Proactive Market Maker.”
Uniswap’s AMM design will get its identify from the fixed product of its worth algorithm. As a substitute of provide and demand figuring out the value of an asset like on many orderbook-based exchanges, Uniswap makes use of the equation x*y=okay.
“X” and “Y” symbolize the availability of a particular token in a pool on Uniswap. As merchants purchase and promote tokens from this pool (i.e., purchase and promote “X” and/or “Y”), the value of every token modifications to maintain “Okay” fixed.
This design is maybe the most well-liked and has helped encourage a variety of recent concepts in decentralized buying and selling. What’s extra, Uniswap has made it simple for anybody to supply liquidity to any ERC-20 token they so select. There isn’t any itemizing consortium or gatekeepers that determine which tokens can be found to commerce.
Sadly, such a design doesn’t come with out its faults. These embrace slippage and impermanent loss, to call a number of.
Unpacking Present DEX Design Flaws
Slippage refers back to the distinction between the value an asset is purchased or offered, and the value that this sale is executed. In occasions of excessive volatility, slippage could be extreme as a result of massive swings in worth occurring between trades and their execution. In crypto buying and selling, this drawback is additional exacerbated by gradual execution occasions native to blockchain know-how.
Outdoors of volatility and gradual execution occasions, illiquid markets are additionally extremely vulnerable to slippage. With a big sufficient commerce and an illiquid sufficient asset, the value of your favourite token might moon or plummet in a near-instant.
On Uniswap, they’ve managed to attenuate slippage for small trades, however massive trades can price merchants a reasonably penny. The DEX affords merchants quite a lot of instruments and settings to raised gauge slippage.
“Skilled Mode” permits merchants to activate excessive slippage trades. Supply: Uniswap
Briefly, one can see a tradeoff that Uniswap makes. In change for at all times providing liquidity for illiquid markets, akin to obscure tokens, they might preserve massive whale merchants at bay as a result of extreme slippage on bigger trades.
The second, barely extra difficult drawback going through Uniswap and some different DEXes, is that of impermanent loss.
As a substitute of a third-party oracle, like Chainlink, offering dwell pricing info, the belongings listed on Uniswap are outlined internally by the algorithm talked about above. This algorithm can thus create costs which may be a lot totally different than on different platforms.
If the value of LINK rises 15% on centralized exchanges, for example, this appreciation could not instantly be realized on Uniswap. There’s then a interval the place arbitrageurs should purchase LINK on Uniswap for a reduced worth, then promote it for 15% extra elsewhere.
Arbitration is thus a standard prevalence, as merchants arrive to both promote costly or purchase low-cost belongings to show a revenue. This habits wouldn’t essentially be a problem, however for LPs on Uniswap. These important brokers on Uniswap can expertise extreme losses as a result of arbitrage exercise within the type of impermanent loss.
LPs should stake their belongings on Uniswap to earn their charges. However throughout massive worth swings and lively arbitration, the quantity of staked belongings will change to maintain “Okay” fixed.
So, as a substitute of merely holding LINK in your pockets and having fun with a 15% hike in worth, it’s possible you’ll discover that your staked LINK on Uniswap has been arbitraged away.

What Is DODO Change?
With the above overview concluded, it’s now time to unpack DODO.
The platform continues to supply on-chain digital asset buying and selling however boasts order execution equitable to centralized buying and selling platforms. LPs and arbitrageurs additionally play an important position on this ecosystem, and the DODO group alleges to have nearly eradicated impermanent loss.
Moreover, although not coated earlier, DODO LPs needn’t provide two sides of a buying and selling pair. To start incomes charges, LPs can add single-asset liquidity to any pool.
It achieves all of those options due partly to an alteration to its market-making algorithm, referred to as “Proactive Market Maker” (PMM). As a substitute of Uniswap’s x*y=okay, DODO leverages the next:
The image “i” represents the market worth of an asset, and “R” refers back to the threat issue. Understanding “R” is essential to understanding how DODO incentivizes excessive liquidity at correct costs.
To determine “i,” DODO will leverage dwell worth feeds from Chainlink, because of a partnership made in August 2020. This knowledge creates a baseline, so the DODO algorithm can keep away from big worth discrepancies related to what’s generally discovered on Uniswap. And as capital for a specific asset accumulates and turns into extra liquid, the “R” operate additionally modifications.
The end result, in accordance with DODO, is as follows:
“Relying on the liquidity within the capital pool, PMM modifications the parameter R in real-time to fine-tune P, the market worth on DODO, so as to maximize fund utilization.”
What finally ends up taking place is that liquidity for a specific asset is then shifted to the value of that asset, in accordance with Chainlink knowledge.
In comparison with Uniswap, DODO affords extra liquidity at market costs. Because the market costs shift, so does the focus of liquidity round that worth. Supply: DODO
One other means to consider the DODO mannequin is to create a real-time market feed as a baseline for costs within the system. Such a mannequin does, nevertheless, place a number of belief in Chainlink knowledge.
If ever Chainlink nodes fail to replace appropriately or come underneath assault, DODO might use incorrect worth info. This may inevitably result in important losses for LPs.
The Workforce and Buyers Behind DODO
Expertise is essential, particularly for DeFi tasks constructing the bottom infrastructure for another monetary system. DODO’s three co-founders are veterans of the blockchain trade.
Mingda Lei is a co-founder at DODO and the architect behind the protocol’s proactive market-making system. Lei beforehand served as a core developer at DDEX, a DeFi margin buying and selling platform, and is a Ph.D. dropout from Peking College.
Qi Wang is a software program developer and based DOS Community, a layer two oracle service based mostly in China. Wang labored for firms like Oracle and Pure Storage as a software program developer earlier than venturing into crypto.
Diane Dai is the third co-founder. She runs a subscription-based WeChat channel referred to as “DeFi Labs” alongside a myriad of different channels.
Though competitors is crowded within the AMM area, DODO lately closed a seed spherical with participation from notable buyers like Framework Ventures, DeFiance Capital, Spencer Midday (DTC Capital), Jason Choi (Spartan Group), Bobby Ong (CoinGecko), and Robert Leshner (Compound).
DODO’s excessive caliber buyers can present the undertaking with ample experience and a community to cement its development. Framework Ventures, specifically, is recognized for bringing synergy between its numerous investments – like Chainlink, Aave, and Synthetix.
Potential Path to Success
Impermanent loss on Uniswap typically finally ends up turning into a everlasting loss. And enormous merchants are delay by 50-50 AMMs due to the deep slippage they incur with bigger commerce sizes. Cumulatively, for this reason primitives like DODO are a step in the correct path.
DODO’s use of worth oracles slightly than purely balancing liquidity round a continuing system permits the AMM to supply merchants and LPs higher phrases. Merchants have entry to liquidity with higher slippage than Uniswap, and LPs solely must deposit one token, probably mitigating impermanent loss woes.
One concern is that with out ample buying and selling volumes, LPs can nonetheless face a loss on DODO. If merchants make the most of liquidity however complete charges earned by LPs is low, the web result’s a loss. For LPs to make regular earnings from market-making on DODO, quantity wants to extend persistently.
At present, the protocol is in a nascent stage, so quantity is maybe much less of a priority than guaranteeing the product works effectively. If every part runs easily, DODO can provide different AMMs a severe run for his or her cash.
Automated liquidity provision coupled with the pricing and liquidity of an orderbook might turn into an efficient combo and the perfect iteration of AMMs.
