Uniswap
Uniswap can be added as a plugin to Ethereum networks. Once a network is running, please select "Plugins" and install Uniswap. This will create a fully fledged Uniswap UI that interacts with your network.
info
This is only supported for forked Ethereum networks
You can connect your wallet and have a similar trading experience as on mainnet. The UI is currently limited to Uniswap v3.
