Uniswap V2 Mainnet Launch!

Uniswap V2, the second iteration of the Uniswap protocol, has been deployed to the Ethereum mainnet!

An audit report and formal verification has already been released and the Uniswap V2 Bug Bounty has been running for over a month.

Developers can begin building on Uniswap V2 immediately! Initial docs and example projects are already available.

Today, the following open source projects are also being released:

  • A migration portal for moving liquidity from Uniswap V1 to Uniswap V2
  • An updated interface for swapping and liquidity provision on Uniswap V2
  • An updated info site for Uniswap V2 analytics

Uniswap V2 has many new features and technical improvements compared with Uniswap V1 including:

  • ERC20 / ERC20 Pairs
  • Price Oracles
  • Flash Swaps
  • And much more!

For full details on the benefits of Uniswap V2 for liquidity providers and traders, please read the Uniswap V2 announcement blog post. For more information on the launch please read below.

Liquidity Migration

The migration portal makes the process of withdrawing liquidity from Uniswap V1 and depositing it into Uniswap V2 fast and simple.

This portal is only for Uniswap V1 liquidity providers. If you are not a Uniswap V1 liquidity provider but wish to use Uniswap V2, you can do so from the updated interface.

Updated Interface

The open source interface has been updated to work with Uniswap V2!

It now supports creating and providing liquidity in ERC20 / ERC20 pairs, such as DAI/USDC.

Swapping logic has been updated to properly route between ERC20 / ERC20 pairs.

While Uniswap V2 uses WETH, this is abstracted in the interface and ETH can be used directly.
