"Uniswap is an Ethereum exchange, built using smart contracts and liquidity pools, as opposed to the order book of a traditional centralized exchange (CEX), such as Binance. With any Ethereum wallet, users can simply connect to the Uniswap application and effortlessly exchange ERC20 tokens without first sending them to the exchange platform account."


"[T]he development of Uniswap was facilitated by Vitalik Buterin’s idea for a decentralized exchange (DEX), which would involve an automated market maker. Actually, the protocol developer himself, Hayden Adams, at first tried to just practice development on Solidity, and later this hobby brought him several grants and $100 000 from the Ethereum Foundation. Now the project went far beyond just entertainment and became one of the most important components of the entire DeFi industry."


"Uniswap scams are not a new happening within the crypto space. Uniswap ETH-based decentralized exchange that offers every project a chance to air its views to the world. Notwithstanding, it’s one of the most misused platforms within the DeFi world, with more entities taking advantage of its name and services."


"Since its ‘V2’ overhaul in May, Uniswap has emerged as a cornerstone of the nascent DeFi ecosystem, with data published by Dune Analytics indicating that Uniswap comprises DeFi’s top pool by total users with 92,000."


"Scam tokens are a growing problem on the decentralized exchange and liquidity pool Uniswap — owing to the protocol’s open listing policy." "Uniswap, allows users to import any new token simply by pasting its address to the Uniswap’s swap menu."


"Cronje is seen in crypto circles as a prolific developer with a Midas touch. Hype and a “fair” launch (and an extremely low 30,000 supply cap) caused the token prices of his first project, YFI, go from under $30 in July to a peak of $42,000 in September. As a result, hopefuls would pile inordinate amounts of money into subsequent Cronje projects—like Keep3r Network and the now-defunct Eminence—to bank on quick profits, even though they weren't fully tested."


"But today, Cronje only released only a product and no token. Perhaps this was to avoid the issue of his loyal userbase plowing into his latest thing and then complaining when there's an issue. But this new tactic, however, didn’t stop scammers from almost instantly issuing fake “DWAP” tokens on decentralized exchange Uniswap to immediately attract traders wanting to pile into the next Cronje moonshot."


"November 22, 2020 - Fake Uniswap LP tokens net scammers $52K."


"Andre Cronje's latest project announcement saw scammers immediately issue fake 'DWAP' tokens. One such scammer made away with $53,000 in under 30 minutes. Over 30 fake DWAP tokens have since been issued."


"André just gave an update about deriswap 30 mins back. Someone created a fake token called $DWAP. 60 addresses in less than 15 mins with 150+ ETH. Aaaaanddd its gone. Take few mins to hover around etherscan before u jump, it’s not that hard."


"Today, after Deriswap was released, the first such scam pool saw an attacker issue fake DWAP tokens, supply the Uniswap pool with 72.4 ETH, conduct a few trades, attract gullible traders, and exit the entire pool with 162.3 ETH about 20 minutes later." "They even sent the illicit DWAP tokens to the ‘yearn:deployer’ contract address to make the issuance seem more legitimate."


"This process netted the scammer over 90.1 ETH, worth over $53,000 at current prices."


"Meanwhile, since then, over 30 DWAP pools have been issued on Uniswap, each attracting liquidity and netting scammers with several ETH for their efforts."


"[T]here could be a lot of fake tokens on the Uniswap platform that mimic the legitimate projects and deceive users into trading their funds for a worthless scam token."


"With any token able to be listed on the platform’s drop-down menu simply by making a GitHub request, the platform’s users are increasingly calling for more stringent vetting to be introduced."


"Uniswap Labs said [July 23rd, 2021] that it was restricting access to dozens of tokens on its trading interface app, including synthetic assets meant to mirror the prices of stock-market giants like Facebook Inc. and Tesla Inc., as well exchange-traded funds such as Invesco’s so-called QQQ that tracks the Nasdaq 100 Index." However, there is no indication of anything done to restrict scam tokens.


"As Uniswap’s protocol is permissionless and both good and bad actors can list tokens through it, you will often see a warning for users to take the initiative in avoiding scammers."


"Rather than searching for tokens or pairs on Uniswap, you can verify you are selecting genuine ones by going via a trusted source, such as the CoinMarketCap or CoinGecko crypto tracking websites. On CoinMarketCap, for example, you can search for the token, select it, then navigate to the trading pairs towards the bottom of the page. If you then click on the relevant pair next to Uniswap, it will take you to the genuine Uniswap page and help you to avoid fake tokens. It also has an option at the top for MetaMask." "Explorers like Etherscan can also be used to check the vital analytics needed to make a more informed decision."

Uniswap allows anyone to list a token. Therefore, there have been a massive number of scams with tokens named similarly to popular projects.


In this case, Deriswap was a real project, but didn't have any token associated. The announcement caused a lot of activity searching for the token, and the opportunistic scammer listed a coin with the same name, netting a substantial sum of $53k.


Ensure platform operators are trained to avoid listing fraudulent tokens.
