Uniswap V2: Everything New with the Decentralised Exchange
Uniswap V2 is the next iteration of the on-chain exchange
Uniswap is an on-chain liquidity protocol on the Ethereum blockchain that enables trustless token swaps, meaning all transactions are executed from smart contracts without the need for an intermediary or trusted party. This decentralised approach to swapping tokens has proven popular with ERC20 token holders to exchange their tokens and provide liquidity to token pairs.
Uniswap launched its second iteration on the Ethereum Mainnet on the 19th May 2020 to coincide with the core contract v1.0.1 release, after testing on the Rinkeby testnet for some time prior to this. The protocol has been used on the Mainnet for over 2 months at the time of writing, and thus far, no major breakages or issues have occurred pertaining to the integrity of the smart contracts.
If you are interested in holding and/or trading Cryptocurrency, Ethereum development, fin-tech, or finance trends in general, Uniswap should be on your radar. It has experienced some rapid growth in the 3rd quarter of 2020 to coincide with the booming DeFi space. Uniswap exists as a standalone service, but can also be integrated into third party wallets or Dapps. In addition to this, other smart contracts rely on Uniswap as a foundation to their services.
