Uniswap

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

This is a global/international case not involving a specific country.

About Uniswap

"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."

"[D]ecentralized exchanges are one of the leading DeFi sectors, whose trading volumes exceeded $1.5 billion and reached the all-time high in June. Uniswap and Curve together processed nearly $800 million, which is more than half of the overall monthly volume."

"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."

"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."

"Decentralized derivatives project Opium took to Twitter on July 7 to warn users that a scam token called Opium and trading under the ticker OPM had been listed on Uniswap despite the project not having a native token."

"Uniswap Scam Warning. A scam token called Opium (OPM) was just listed on @UniswapProtocol. Opium does not have a native token at the moment. Please be aware and stay safe."

"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."
