Simple tool for checking and creating new Uniswap V2 Pairs across multiple networks
This is the tool I wish existed when I was building on top of Uniswap V2 a number of weeks ago! It's a simple frontend for devs to check whether a Pair contract address exists for two given tokens. If not, there's the option to create it. The user can enter two token contract addresses and click "Find Pair!". If a Pair contract exists already, its address will be displayed. If it does not exist, the user will be asked whether they want to create it. With Metamask, the pair finder / pair creator features can be used on mainnet as well as other networks. If the token addresses are invalid, or an error occurs for any other reason, the error message will be displayed. Token addresses / pair address / error can be cleared by clicking the trash can. The user can view the 10 latest mainnet pairs via the Uniswap V2 subgraph, by clicking "Latest Pairs".
