Hayden Adams took a $65,000 grant and turned it right into a $2 billion protocol; no different developer has come near that.
By means of memes, Twitter ratios and coordinated pump-and-dumps, the DeFi Degen is the dominant life type driving a pernicious a part of decentralized finance (DeFi), a crypto subculture identified for model loyalty verging on spiritual zealotry.
This text is a part of CoinDesk’s Most Influential 2020 – an inventory of impactful individuals in crypto chosen by readers and workers. The NFT of the artwork beneath, by XCopy, is obtainable for public sale at Nifty Gateway, with 50% of the sale going to charity.
Oddly, the person answerable for the curler coaster of “DeFi Summer season” couldn’t be extra totally different from a degenerate. Hayden Adams, creator of the Uniswap protocol, is a soft-spoken developer, first dragged into cryptocurrency much less so for the cash than the chance to make one thing of himself.
But, by means of his protocol, he could the truth is be King of the DeFi Degens.
After being laid off from his junior engineering place at Siemens and residing at dwelling together with his mother and father, a profession alternative got here knocking: Uniswap, the permissionless token alternate constructed on the Ethereum blockchain.
Since Might, his challenge’s complete worth underneath lock (TVL), or the greenback worth of tokens locked within the good contract of a given decentralized lending challenge, is up some 3,500%, from $35 million to $1.3 billion. His code proves a decentralized alternate (DEX) shouldn’t be solely attainable however greater than able to matching heavyweight rivals like Coinbase pound for pound.
A good friend named Karl
All Ethereum tasks might be discovered first in a Vitalik Buterin weblog submit – or so it looks as if from outdoors wanting in.
Uniswap isn’t any totally different. Adams, 26, was launched to his future challenge, an automatic market maker (AMM), by way of a 2016 Buterin Reddit submit entitled, “Let’s run on-chain decentralized exchanges the way in which we run prediction markets.” That submit itself was based on work from prediction market Gnosis and even earlier theory from libertarian-leaning economist Robin Hanson.

Buterin’s article was despatched to Adams by Karl Floersch within the fall of 2017 and would turn into his first challenge. Floersch was a school good friend of Adams’ then working on the Ethereum Basis. He’s now the chief technical officer at blockchain scaling agency Optimism.
Adams and Floersch attended Stony Brook College in New York, an schooling Floersch described as ok to get the job finished. Nothing flashy, simply low cost and strong. There, Floersch grew to become involved in Ethereum and shortly entered the crypto world after graduating.
Adams, then again, joined Siemens as a automotive engineer engaged on computational fluid dynamics and was the final “normie” good friend Floersch had, Floersch advised CoinDesk in a telephone interview. Adams had resisted transferring into crypto for years, even passing up ether (ETH) at $0.30 a coin.
Adams was let go by Siemens after solely a 12 months, leaving him unsure about his future even when he hadn’t been notably keen on working for the German engineering large.
“From a perspective of ‘I don’t know what I’m going to do with my life,’ it was scary on the time. I used to be residing at dwelling [in the New York suburbs] for some time,” Adams stated.
Be taught to code
Two seemingly inconsequential choices Adams made in 2017 would set the stage for 2020’s DeFi bull run. First, he purchased ETH in March 2017. Second, he discovered to code whereas residing at his mother and father’ home.
Fortunately, Floersch had all of it discovered for Adams. There was an acute lack of good contract builders for Ethereum, a wise contract blockchain, Floersch advised Adams. So, Adams started to study JavaScript and Solidity as inspired by a dramatic upswing within the worth of cryptocurrencies in the summertime of 2017.
“It was a really bizarre time. I used to be getting very into Ethereum and from that perspective it was a very great point,” Adams stated. The layoff “positively turned out to be the very best factor that ever occurred to me.”
Adams quickly felt the necessity to work on a “actual challenge” to remain motivated. That led him to the invention of automated market making, despite Adams’ unfamiliarity with finance and markets. Right here, Floersch stepped in once more, introducing Adams to the idea of a decentralized alternate.
Adams’ story, then, isn’t too distant from many who enter the cryptocurrency area and hit it massive. Spurred on by the curiosities of cryptocurrency, Adams went from unemployed and directionless to a programmer inside months. Three years later, he’s the face behind the most trafficked Ethereum dapp.
“Hayden’s exceptional story is one thing that couldn’t have occurred outdoors of Ethereum and the DeFi ecosystem, which have dramatically lowered the price of implementing world-changing concepts like Uniswap,” Paradigm researcher Dan Robinson stated in a Telegram message.
“However it additionally couldn’t have occurred with out somebody like Hayden. His tenacity and clearness of imaginative and prescient are an inspiration to me and to numerous crypto founders that I’ve spoken to,” Robinson stated.
The early days of v1
Adams grew to become obsessed. He lived in Brooklyn, N.Y., off his ETH stash, programming away for months on a Uniswap proof-of-concept.
Uniswap is as a lot a product of Adams’ hours as it’s the better Ethereum ecosystem, he stated.
Adams started making journeys to varied conferences in Canada and New York Metropolis. In actual fact, Adams flew to Seoul, South Korea, to attend a crypto convention for which he didn’t have a ticket (he wasn’t allowed in, however he was in a position to speak about Uniswap with Buterin). By day he sat within the MakerDAO or Stability workplaces; by night time he coded Uniswap. (Stability is now the Ethereum pockets Rainbow).
It wasn’t unhealthy work, notably in comparison with modeling automotive efficiencies at Siemens:
“Programming with cash is simply actually enjoyable,” he stated. “Having the ability to write features that ship cash and obtain cash in a local method may be very enjoyable.”.
An Ethereum Basis grant of $65,000 – a far cry from AMM project Bancor, which raised $150 million in a 2017 initial coin offering (ICO) – enabled an intensive audit of the challenge’s code. (Some years later, Bancor appears to have misplaced the AMM race, with Nomics reporting $1.23 million in 24-hour quantity on Dec. 7, in comparison with Uniswap’s $309 million).
Adams additionally had moved Uniswap from Solidity to Vyper, a programming language goal constructed for Ethereum good contracts. Apparently, Uniswap was one of many first tasks constructed on Vyper, which he offered at 2018’s EdCon in Toronto.
Uniswap v1 launched at DevCon 4 in November 2018. Whereas promising, it lacked just a few technical options to make it actually market transferring. For one, orders may solely be routed by means of ETH and a token. That restricted the AMMs’ performance significantly. It additionally didn’t assist to debut Uniswap v1 within the midst of a crypto bear market, the place ETH drew down some 95% from its peak worth worth.
The good liquidity wars
But, it took a pseudonymous competitor to actually make Uniswap shine in maybe probably the most dramatic second of DeFi Summer season: SushiSwap, Chef Nomi and the liquidity wars. Though Uniswap v2 launched in May, its liquidity and every day volumes remained low in comparison with the place it sits now.
That’s till Chef Nomi, the pseudonymous cofounder of SushiSwap, reared his or her head this previous September. A extra combative DeFi Degen, Chef Nomi was in a position to create hundreds of millions of dollars of TVL on Uniswap by providing a token reward, SUSHI, for farming on Uniswap. Then he lured away capital from Uniswap to SushiSwap by providing larger returns to liquidity suppliers (LPs) in what’s now known as “vampire mining.”
Uniswap is open supply, that means individuals can clone its code and launch their very own variant. What you’ll be able to’t clone is the customers and, due to this fact, the liquidity.

In a salvo again, Uniwap issued its personal token, UNI, in what amounted to crypto’s personal stimulus test. Hundreds of thousands of UNI had been distributed to any early builders, buyers, Uniswap $SOCK holders (sure, tokenized socks) and any pockets that had interacted with the Uniswap contracts.
In just a few keystrokes, Adams not solely received the AMM liquidity wars, he grew to become everybody’s favourite cryptocurrency developer. It additionally didn’t assist that SushiSwap’s pseudonymous chef absconded with (and then returned) a founder’s reward of SUSHI tokens price $13 million.
To Uniswap went the spoils: Because the turf battle, Uniswap’s TVL has not dipped beneath $1 billion and broke $3 billion for quite a few days in November.
Competitors with SushiSwap and the following UNI airdrop pushed Uniswap to new ranges of recognition. In actual fact, the challenge, begun within the lulls of his unemployment, broke Coinbase’s daily trading volume in September for the primary time in DeFi’s personal “flippening.”
“When you had been to ask me a 12 months in the past when Uniswap was going to report extra quantity for a single day of Coinbase, I might in all probability say 2021. However what we’ve seen is that in September of this 12 months, Uniswap did $15 billion in quantity and Coinbase did [about] $12 billion,” Adams stated.
What’s a Uniswap, anyway?
Uniswap is a decentralized utility, or dapp, constructed on the Ethereum blockchain. It’s a wise contract that facilitates token trades between totally different events.
(Its title was initially going to be Unipeg, Adams wrote in a Uniswap history blog. Buterin, who provided tips about the challenge every time he and Adams crossed paths, thought Uniswap made extra sense, so Adams went with it).
Uniswap is probably the most used Ethereum utility when taking a look at contract calls, second solely to stablecoin tether (USDT) total. There are some 25,000 tokens with trading pools on the alternate, though solely a handful of them have significant liquidity.
These few swimming pools matter, although. Uniswap’s worth proposition as an alternate feeds upon Ethereum and vice versa: Ethereum is a blockchain for decentralized purposes, particularly for launching your personal token, whereas Uniswap is an exchange for those tokens.
A venue for buying and selling Ethereum tokens had did not sufficiently develop after Ethereum’s 2015 launch. In 2016 and 2017, decentralized exchanges had been much more so of their infancy than now, with Adams pointing to EtherDelta as the very best such platform.
Uniswap addresses just a few points with DEXs reminiscent of poor consumer interfaces, unhealthy quotes and excessive slippage by means of its underlying infrastructure. Adams’ alternate is a type of AMM. To be extra particular, it’s a relentless product market, meaning there’s always liquidity for a token.
Automated market making
What Uniswap’s good contract does, amongst different issues, is convey unparalleled entry to the within mechanics of crypto exchanges.
“At its core, Uniswap is about making finance extra accessible,” Adams stated in an e-mail. “That is most clearly seen [by] how a lot simpler it’s to take part in automated market making in comparison with conventional market making.”
In different phrases, it democratizes market making.
Uniswap works the next method: Traders deposit equal quantities in worth of tokens into the dapps contracts. Uniswap’s good contracts set costs for every token in opposition to the quantity of reserves of the 2 tokens in opposition to one another. For instance, Uniswap gives ether on the market together with its native token UNI. In a ETH/UNI pool, ETH is priced in UNI and UNI is priced in ETH.
Fixed product market AMMs are totally different from conventional market making in just a few methods. Mainly, AMMs like Uniswap have liquidity at each worth. That’s as a result of asset swimming pools are matched to create a worth primarily based on an algebraic equation known as a bonding curve. Uniswap’s curve is an invariant with the quantity of asset X in reserve multiplied by the quantity of asset Y’s reserve, equaling the worth Okay.
These worth choices are additionally symmetrical, CoinRoutes CTO Ian Weisberger advised CoinDesk in a telephone interview. The bid and the ask are all the time the identical at a given time, not like on conventional exchanges.
Traders are incentivized to deposit funds into the protocol by garnering a share of buying and selling charges for offering liquidity. These buyers are known as liquidity suppliers however they perform equally to market makers, simply extremely passive ones.
Market making is the apply of providing bids and asks on an alternate. It’s a extremely technical endeavor that necessitates not solely the power to create brief run scripts that supply costs, however preserve a finger in the marketplace’s pulse to earn revenue. Anybody could make markets, but it surely takes some talent to show a revenue and never “blow up” your account.
A Uniswap LP’s capability to earn funds passively is placing not solely as a result of it permits Uniswap to perform, but in addition due to the bigger implications for token holders who turn into a part of an alternate’s every day operations by way of the smallest of thresholds. A small portion of the commerce is left within the pool to develop the market whereas one other portion, 30 foundation factors (bps), is given to LPs for long-term progress.
The incomes scheme has had some endurance for the reason that liquidity wars, too. About half the challenge’s TVL left the Uniswap’s platform following the tip of UNI farming rewards in mid-November. Nonetheless, it’s ok at $1.33 billion TVL to internet fifth place, based on DeFi Pulse.
Paradigm’s questions
Funnily sufficient, Uniswap’s creators are nonetheless making an attempt to determine precisely why passive market making on Uniswap works.
In mid-October, Paradigm associate and quantitative analyst Charlie Noyes spit out a brand new blog describing three issues he and Paradigm have but to reply about Uniswap – a challenge wherein they maintain a big stake. (These questions declare to have been addressed here).
Noyes, Paradigm and builders like Adams are principally targeted on the concept that markets can enfranchise retail merchants by making them a part of the sport. Anybody can turn into a market maker on Uniswap with just a few tokens and get a lower of the motion. Thus the spirit of Uniswap shouldn’t be dissimilar from the final premise of Bitcoin and its try and free cash from authorities by democratizing the shopping for and promoting of tokens.
The weblog’s questions principally take into account the dynamics of offering liquidity to Uniswap and what trade-offs exist. As an example, what’s the optimum payment to cost for a commerce on Uniswap? Or, how does liquidity provisioning get up in opposition to merely holding the identical digital asset however not inserting it in Uniswaps’ swimming pools?
Noyes’ questions, to the uninformed, are hardly intelligible. And forays into the mathematics and accompanying commentary solely reveal how deep the barrel is from which Noyes is pulling questions. For instance, what’s poisonous move?
The most important query is whether or not liquidity provisioning in an AMM is extra worthwhile than merely “hodling” an asset, given the cryptocurrencies’ dramatic worth swings.
If you mix market swings with buying and selling, you get arbitrage alternatives. Remembering that Uniswap creates its personal costs slightly than porting them into the alternate, you’ll be able to see that LP holdings are susceptible to being picked off when costs swing in opposition to LPs in what known as “impermanent loss.”
However, given the rise in utilization, the market continues to impress the significance of those questions.
Certainly, Uniswap’s largest asset swimming pools like ETH/USDT boasts extra liquidity than many centralized venues, that means merchants will greater than possible get the very best quote on a DEX than a centralized alternate (CEX) for sure token pairs. Exchanges reminiscent of Coinbase are even taking a look at including comparable swimming pools.
That doesn’t imply it’s all easy crusing. Regular exchanges can provide costs differing from the market worth. In addition they give extra flexibility for preempting market circumstances and permitting merchants to set bids at totally different ranges. Certainly, Uniswap’s distinctive providing has been a central matter to merchants because it exploded in reputation this summer time.
Impermanent loss
It stays unknown how Uniswap can match into a mean particular person’s portfolio – far more so than including crypto to a portfolio, in fact. As Noyes writes, it primarily has to do with determining the right way to worth liquidity provisioning. Doing so is tough.
Placing a sticker tag on liquidity provisioning relies on a brand new phrase within the crypto lexicon, that being “impermanent loss.” Impermanent loss makes an attempt to measure the worth loss an LP takes when a token worth strikes in opposition to the holder in a pool. It’s impermanent as a result of LPs usually don’t take away funds from a pool actively – they’re most of the time passive buyers – and so the worth of the token may get better.

Impermanent loss isn’t one thing new to Max Bonen, founding father of OTC buying and selling desk B2C2, speaking to CoinDesk in a telephone interview. Quite, it’s a poor dealer’s outdated good friend: adversarial choice. Uniswap’s dependency on outdoors forces to set market costs forces LPs to eat unhealthy trades. The one factor that stands between an LP and impermanent loss is the 30 bps payment reserved for LPs for each Uniswap commerce.
“In my view, there’s an iron regulation of markets that the price of trades and the unfold goes to be a perform of adversarial choice,” Bonen stated.
Bonen additional simplified Uniswap’s drawback to an AMM’s properties being open and due to this fact gamable. He stated AMMs will proceed to have a market so long as they will outperform centralized alternate quotes, however that any market set by a curve will undergo from inherent issues centralized order books won’t.
This may be seen actively in markets, Weisberger advised CoinDesk. Uniswap worth markets are largely flat till the arbitrage alternative from a commerce surpasses the payment and value of execution on Ethereum.
The value “will mainly keep flat for a time frame whereas different markets have moved. It’s solely when the fee-adjusted worth strikes sufficient. It could actually get about 30 foundation factors out of whack with none adverse affect as a result of the payment is 30 foundation factors to take there,” Weisberger stated.
A decentralized future
When you ran a centralized alternate, what would you do to cease the bleeding to decentralized exchanges? That’s the final query I lobbed to Adams as our dialog closed.
After all, he’s fairly bullish on decentralization:
“I mainly consider that decentralized infrastructure would be the underlying factor for the whole lot. All the pieces can be settled on Ethereum. … You’re going to have decentralized infrastructure on the heart. I do suppose that’s in the end the place most of liquidity will dwell,” Adams stated.
Centralized venues do have a bonus by way of custody, he stated. Some buyers choose trusted events to carry funds. Nonetheless, he envisions a future the place merchants use Coinbase to commerce for tokens however Coinbase makes use of Uniswap.
“Centralized exchanges will doubtlessly turn into custodial interfaces to decentralized platforms,” he stated.
Adams expects Uniswap to proceed sucking up spare liquidity pushed by AMM incentives whereas different events start constructing on prime of Uniswap itself. Some 200 groups are at present constructing totally different tasks leveraging Uniswap as a base layer, he stated, reminiscent of for margin buying and selling.
Though cautious by nature, Adams has set his eyes on the prize: Uniswap turning into the highest crypto alternate by quantity someday subsequent 12 months. That prize is at present held by Binance, one other crypto unicorn, and would require a 10-fold improve in quantity, Adams stated.
“All the pieces is going on lots quicker than my predictions would have been a 12 months in the past.”
