"Uniswap is an exchange protocol that allows users to trustlessly swap ERC20 tokens. Rather using the traditional order book model, Uniswap pools tokens into smart contracts and users trade against these liquidity pools. Anyone can swap tokens, add tokens to a pool to earn fees, or list a token on Uniswap.

Uniswap is a decentralized ERC-20 token exchange, and it's not just for tokens. It also supports Ethereum, and the beauty of Uniswap is you can exchange ETH for any other ERC-20 token in a decentralized fashion. There's no company involved, no KYC, and there's no person involved that's mediating things.

Uniswap smart contracts hold liquidity reserves of various tokens, and trades are executed directly against these reserves. Prices are set automatically using the constant product market maker mechanism, which keeps overall reserves in relative equilibrium. Reserves are pooled between a network of liquidity providers who supply the system with tokens in exchange for a proportional share of transaction fees. The Uniswap Exchange is an opensource front-end interface for traders and liquidity providers to easily interact with Uniswap's smart contracts."

The U.S. Securities and Exchange Commission (SEC) has dropped its investigation into Uniswap Labs, the Brooklyn-based company behind the decentralized protocol of the same name. The SEC's decision to close its investigation into Uniswap Labs is the latest in a wave of similarly-dropped investigations into crypto companies, including Robinhood Crypto and non-fungible token marketplace OpenSea. The SEC has also agreed to drop its case against Coinbase, pending approval from the agency's commissioners, according to the crypto exchange.

SushiSwap, created by animated and anonymous character Chef Nomi, is a fork of VC-backed UniSwap, a decentralized exchange. SushiSwap promised to take all of the best features of UniSwap and improve on its governance by creating a community owned fork using a voting token called SUSHI. Anyone who joined the community could become a liquidity provider by staking SUSHI and ETH on UniSwap, which would eventually be transferred to SushiSwap when it is launched. The combination of your liquidity stake, or voting power, is your *SUSHIPOWAH*. Chef Nomi swapped his Sushi LP tokens for some $13 million of Ethereum (ETH) worth about $13 million in what bears strong resemblance to an "exit scam."

And while Bitcoin has plunged by 15% on a seven-day period, dragging most of the cryptocurrency market along with it, some altcoins have survived the drop and massive price correction: Chainlink (LINK), Uniswap (UNI), and Polkadot (DOT) have recorded gains of 11%, 21%, and 20% over the same seven-day period.

For the first time, monthly trade volume on decentralized exchange (DEX) Uniswap exceeded that of centralized exchange (CEX) Coinbase. During September, Uniswap saw approximately $15.4 billion in volume - making up 65% of the total reported by DEXs for that month, versus Coinbases's $13.6 billion. The DEX-to-CEX ratio rose to 13.9% in September, a new high. In August, that ratio was 6.06%.

Decentralized non-custodial crypto trading platform ShapeShift will sunset its 6+ year business of trading directly with customers and now route orders through decentralized finance (DeFi) applications to get rid of know-your-customer (KYC) requirements. These multiple decentralized exchanges (DEX) will include Uniswap, Balancer, Curve, Bancor, Kyber, 0x, mStable among about a dozen others. DEXs, which operate as trading systems on top of blockchains, such as Ethereum, have eaten into centralized exchange volumes over 2020. For example, Uniswap cites itself as the fifth-largest spot-trading crypto exchange. https://erikvoorhees.medium.com/no-more-kyc-with-shapeshift-6d95a3e63ddf

Trading volume on decentralized crypto exchanges (DEXs) has surged in the last year - and is up over 1500% since January 1st. The growth has been driven by a rising demand to trade ERC20 tokens, accompanying a booming decentralized finance (DeFi) sector on Ethereum (ETH). The top 3 exchanges Uniswap, Balancer and Curve accounting for over 90% of all DEX volume. Of these, Uniswap, an open-source project developed by Hayden Adams that allows users to swap in and out of ERC-20 tokens, is far and away the leader with a market share of 67%.

"DeFi and DEXs have recently attracted much attention. Uniswap raised in October 2022 a $165 million Series B funding round that valued the company at $1.7 billion, and DEXs globally are profiting from the hit that confidence in CEXs suffered following the FTX fallout. We provide in this first article a general overview of DeFi, DEXs and DAOs, focusing on Uniswap V3. In the second part of this article, we will cover a more technical analysis of price discovery and on-chain/off-chain arbitrage opportunities."

Decentralized exchange (DEX) volumes are up 236% from Q4 2020, Uniswap leading the way as volumes continue to rise in lockstep with asset prices.

Decentralized exchanges (DEXs) ended the month of February with the highest monthly volume on record, according to data gathered by The Block. February's monthly volume hit a new high of approximately $72.89 billion, increasing by $12 billion from January. Uniswap continued to lead in the DEX space, making up most of the monthly volume with $36.6 billion. SushiSwap and Curve came in second, hitting $14.93 billion and $4.42 billion respectively.

FEI is a reserve-backed stablecoin that works through a direct incentive method, in which FEI can give users bonuses or charge fees for making trades that help it maintain its dollar peg. Users can buy FEI from the protocol, and the protocol takes those assets in reserve. The asset traded belongs to the Fei protocol after the trade. The assets in reserve could even be under-collateralized, and the assets would be deployed elsewhere, such as on the secondary market or - later - in yield-generating projects. Fei's "genesis launch" is set for March 22, when users will be able to post ETH to get FEI tokens. Early participants in the sale and in the protocol's liquidity pools on DeFi exchange Uniswap will be incentivized with TRIBE, the project's governance token.

Ethereum transaction fees, which have been growing larger, are back down to 2020 levels. However, that's because demand for Ethereum and Ethereum-based DeFi protocols has fallen, along with prices, as partly evidenced by a 28% drop in Uniswap trades from a mid-May peak. Ethereum transfer volume, as measured in dollars, has declined by 60% in two weeks, according to a recent report by Glassnode Insights."

Decentralized exchanges (DEX) are on track to surpass previous all-time high volumes. They have already transferred more than $27 billion in transaction volume so far in January, the second-highest total since September 2020's $29 billion. DEX use smart contracts on blockchain networks like Ethereum to let users swap between digital assets without transferring tokens to an exchange wallet or verifying their identity. Uniswap is the most popular DEX, responsible for more than 45% of volume in the last week, with Sushiswap accounting for more than 22%.

Opium Finance has released collateralized debt obligation products (CDOs) for Compound Finance's automated lending markets. Opium is a decentralized finance (DeFi) protocol that allows for creating, settling, and trading decentralized derivatives. Compound Finance is an algorithmic, autonomous interest rate DeFi protocol that allows for the creation of money markets on the Ethereum blockchain. Investors can put up the Compound debt token cDai - and soon Uniswap tokens - to diversify exposure to DeFi lending markets. Opium's product pays out structured returns to both a senior and junior risk tranche in exchange. The former tranche offers a 7% fixed return on DAI (a crypto-backed USD-pegged stablecoin) at maturity, while the latter pool offers a variable rate paid out after filling up the senior tranche's return.

January decentralized exchange (DEX) trading volume soared to set an all-time high of $56 billion, eclipsing the previous record of $26 billion from September 2020, according to data from Dune Analytics. Uniswap represented over 45% of total DEX volume ($26 billion traded in January) with Sushiswap claiming nearly 22% ($12.2 billion).

Ethereum's gas fees are spiking to record highs once again, rendering many DeFi protocols practically unusable for traders. Average ETH transaction fees are now at a record $17.67. As many DeFi projects require the execution of complex smart contracts, some reports show that fees associated with using these protocols now exceed $1,000. A single large transaction on the Synthetix Network was estimated at above $1,100, while even simple swaps using Uniswap and SushiSwap cost anywhere from $40 to $75. Ethereum is not alone when it comes to soaring transaction fees, with Bitcoin's average transaction costing over $14 at the moment. EIP-1559 may reduce this fee volatility.

Peer-to-peer commerce company Origin launched Origin Dollars, or OUSD, a stablecoin whose reserves leverage decentralized finance (DeFi) so that balances grow wherever it resides, no staking or account required. OUSD will be backed one-for-one by the three big stablecoins on Ethereum: Tether's USDT, Circle and Coinbase's USDC and MakerDAO's DAI. Users can mint OUSD by depositing any of those three into Origin's new app, or they can just buy it on Uniswap. Either way, the OUSD will just start growing in their wallet, no further action needed.

Tether (USDT), with a market cap surpassing $16 billion, continues to hold the lion's share of stablecoins in circulation, but two smaller rivals are trouncing it in crypto's hottest market this year, decentralized finance (DeFi). Measured by the total value locked in six of the most popular DeFi protocols - Compound, Maker, Uniswap, Curve, Aave and Balancer - USD coin (USDC) is in the lead among stablecoins followed by dai (DAI), the native stablecoin to MakerDAO. USDC and DAI have market caps of $2.74 billion and $608 million, respectively.
