What is Uniswap? A short guide to the token swap exchange


  • Uniswap is an Ethereum-based decentralized alternate (DEX) that enables anybody to swap ERC20 tokens.
  • In September 2020, Uniswap launched its UNI governance token with an airdrop to anybody who had used the protocol earlier than September 1.
  • Uniswap V3 launched in Might 2021, including new options together with concentrated liquidity and a number of payment tiers.

The burgeoning decentralized finance (DeFi) ecosystem goals to make use of decentralized, non-custodial monetary merchandise to exchange centralized middlemen in monetary purposes reminiscent of loans, insurance coverage and derivatives.

Uniswap is an instance of one of many core merchandise within the DeFi ecosystem, the decentralized crypto alternate, or DEX. DEXs goal to resolve most of the issues of their centralized counterparts, together with the danger of hacking, mismanagement, and arbitrary charges. Nonetheless, decentralized exchanges have their very own issues, primarily lack of liquidity—which implies a scarcity of amount of cash sloshing round an alternate that makes buying and selling quicker and extra environment friendly.

Uniswap is making an attempt to resolve decentralized exchanges’ liquidity drawback, by permitting the alternate to swap tokens with out counting on consumers and sellers creating that liquidity.

Under we discover how Uniswap works—and the way it turned one of many main decentralized exchanges constructed on Ethereum.

What’s Uniswap?

Uniswap is a protocol on Ethereum for swapping ERC20 tokens. In contrast to most exchanges, that are designed to take charges, Uniswap is designed to perform as a public good—a device for the group to commerce tokens with out platform charges or middlemen. Additionally in contrast to most exchanges, which match consumers and sellers to find out costs and execute trades, Uniswap makes use of a simple arithmetic equation and swimming pools of tokens and ETH to do the identical job.

Do you know?

Uniswap was created by Hayden Adams, who was impressed to create the protocol by a post made by Ethereum founder Vitalik Buterin.

What’s so particular about Uniswap?

Uniswap’s primary distinction from different decentralized exchanges is using a pricing mechanism known as the “Fixed Product Market Maker Mannequin.”

Any token could be added to Uniswap by funding it with an equal worth of ETH and the ERC20 token being traded. For instance, when you wished to make an alternate for an altcoin known as Durian Token, you’d launch a brand new Uniswap sensible contract for Durian Token and create a liquidity pool with–for instance–$10 price of Durian Token and $10 price of ETH.

The place Uniswap differs is that as an alternative of connecting consumers and sellers to find out the value of Durian Token, Uniswap makes use of a relentless equation: x * y = ok.

Within the equation, x and y signify the amount of ETH and ERC20 tokens obtainable in a liquidity pool and ok is a continuing worth. This equation makes use of the stability between the ETH and ERC20 tokens–and provide and demand–to find out the value of a specific token. Every time somebody buys Durian Token with ETH, the provision of Durian Token decreases whereas the provision of ETH will increase–the value of Durian Token goes up.

Because of this, the value of tokens on Uniswap can solely change if trades happen. Basically what Uniswap is doing is balancing out the worth of tokens, and the swapping of them primarily based on how a lot folks need to purchase and promote them.

What else is completely different about Uniswap?

Completely any ERC20 token could be listed on Uniswap–no permission required. Every token has its personal sensible contract and liquidity pool–if one doesn’t exist, it may be created simply.

As soon as a token has its personal alternate sensible contract and liquidity pool, anybody can commerce the token or contribute to the liquidity pool whereas incomes a liquidity supplier payment of 0.3%. To contribute to a liquidity pool, you want an equal worth of ETH and ERC20 tokens.

How are Uniswap tokens produced?

Every time new ETH/ERC20 tokens are contributed to a Uniswap liquidity pool, the contributor receives a “pool token”, which can be an ERC20 token.

Pool tokens are created at any time when funds are deposited into the pool and as an ERC20 token, pool tokens could be freely exchanged, moved, and utilized in different dapps. When funds are reclaimed, the pool tokens are burned or destroyed. Every pool token represents a person’s share of the pool’s complete property and share of the pool’s 0.3% buying and selling payment.

Since Uniswap is an open protocol of sensible contracts, various completely different front-end person interfaces have already been created for it. For instance, InstaDApp permits you to add funds into Uniswap swimming pools while not having to entry the official Uniswap person interface.

Interfaces reminiscent of Zapper.fi permit customers so as to add funds to Uniswap swimming pools utilizing simply ETH as an alternative of ETH and one other token. The interface even gives easy one-click options for buying pool tokens together with bZx token methods.

With an array of official and unoffical assets for builders to construct on the protocol, we must always count on to see many extra integrations between Uniswap’s distinctive token swapping system and new decentralized finance (DeFi) merchandise within the coming years.

Uniswap V2 and V3

Although Uniswap launched again in November 2018, it wasn’t till comparatively just lately that the protocol started to see important traction.

The discharge of Uniswap V2 in Might 2020 noticed a serious improve that enables for direct ERC20 to ERC20 swaps, slicing Wrapped Ether (WETH) out of the equation the place doable. Uniswap V2 additionally added help for incompatible ERC20 tokens like OmiseGo (OMG) and Tether (USDT), and added a number of technical improvements that make it extra fascinating to make use of.

As liquidity mining and yield farming platforms dramatically elevated in reputation in 2020, Uniswap noticed a corresponding surge in curiosity, since many DeFi platforms permit Uniswap liquidity suppliers to see an extra return on their LP tokens.

This, together with the 0.3% alternate charges distributed to liquidity suppliers—and the platform’s reputation as a launchpad for fashionable DeFi mission tokens—has seen Uniswap rise the ranks to grow to be one of many leading DeFi platforms by complete worth locked (TVL)—a measure of the entire worth of crypto property locked up within the platform.

In Might 2021, Uniswap V3 launched, with the newest iteration of the DEX including various new options. First up is concentrated liquidity, which allows liquidity suppliers to allocate liquidity inside a customized value vary. That, in flip, signifies that merchants do not should put as a lot capital on the road to realize outcomes.

V3 additionally provides extra payment tiers, enabling merchants to higher decide their threat degree when buying and selling unstable property (which may change in value between when a commerce’s initiated and executed). It additionally provides “simpler and cheaper” oracles, which ensures that the DEX’s value knowledge is updated.

Lastly (and maybe least primarily) it additionally generates non-fungible tokens (NFTs) primarily based on LP positions, turning them into “on-chain generated artwork”.

UNI token launch and airdrop

In September 2020, Uniswap launched UNI, the community’s governance token, airdropping 400 UNI tokens to each pockets handle that had interacted with the Uniswap protocol earlier than September 1.

From a distribution of 150 million UNI tokens, round 66 million have been claimed within the first 24 hours following the airdrop. After distributing 40% of the tokens within the first 12 months, it’s going to taper down by 10 proportion factors in every subsequent 12 months, till all of the tokens have been allotted.

Uniswap plans to distribute a capped complete of 1 billion UNI over 4 years, with 60% earmarked for distribution to the group, 21.5% allotted to Uniswap workers, and the remaining 18.5% going to buyers and advisors.

As a governance token, UNI entitles holders to a vote in how the protocol is run, affording them fast possession of Uniswap governance, the UNI group treasury, the protocol payment change, eth ENS, the Uniswap Default Checklist (tokens.uniswap.eth) and SOCKS liquidity tokens. The token was shortly listed on the Coinbase Professional alternate, and shortly after on the principle Coinbase alternate.

Uniswap’s token launch could be thought of a response to the rise of SushiSwap, a clone of the protocol that added a token to encourage utilization. In a extra direct problem, SushiSwap additionally tried to empty Uniswap of liquidity by a course of known as “vampire mining”.

Current developments

In lower than a 12 months, Uniswap V2 has propelled the platform to meteoric development.

In February 2021, it turned the primary decentralized alternate to course of greater than $100 billion in buying and selling quantity, and now incessantly exceeds $1 billion in buying and selling quantity every day. This efficiency has seen it grow to be not solely the most important DEX by buying and selling quantity, however one of many high 5 hottest exchanges interval.

In the meantime, the Uniswap governance token (UNI) has climbed to grow to be the tenth largest cryptocurrency by market capitalization after reaching a peak worth of over $44. This was no less than partially pushed by the rising reputation of yield farming swimming pools, a lot of which require customers to carry UNI or Uniswap LP tokens.

The platform additionally discovered itself on the heart of the latest Unisocks (SOCKS) craze, a token backed by a bodily pair of socks. Though the primary pair offered for simply $12, in February 2021, a singular sale format that makes use of a bonding curve to set the value noticed one pair promote for a whopping $92,000.

However it hasn’t all been clean crusing for Uniswap. Because of large congestion on the Ethereum community, transaction charges have shot by the roof—making buying and selling on Uniswap an costly process, significantly when regarding low-value trades.

This has seen the proliferation and development of an enormous vary of different platforms, together with TRON’s JustSwap, Qtum’s QiSwap, and Kyber Community—all of which promise quicker transitions, decrease charges, or each. Uniswap additionally noticed its each day transaction quantity briefly exceeded by PancakeSwap—the same automated market maker (AMM) constructed on Binance Sensible Chain.

However Uniswap’s place as one of many main DEXs has given it appreciable clout. Some wish to leverage that because the DeFi sector grows—and, inevitably, comes underneath the gaze of regulators. In Might 2021, members of the Uniswap group launched a governance proposal to arrange a “political protection” fund with a finances of 1-1.5 million UNI.

The goal of the fund is to preempt regulatory and tax threats utilizing legal professionals, lobbyists and organizers, enabling the nascent DeFi area to counter “large spending from conventional finance gamers.”

With the likes of the SEC and CFTC now contemplating the query of DeFi regulation, Uniswap might have a combat on its fingers.
