Nah the only Uniswap experience I have so far is thru research and reading their website and docs. But essentially it requires an ETH token contract that represents "wrapped HIVE".

Of course the balances cannot just be created out of thin air. So the ETH token contract would have to mint new tokens as they are burned or transferred from a Hive user account to the built in contract on chain.

After a burning transfer can be verified, the ETH contract should mint those same amount of wHIVE tokens and allow a user to claim them with the private key that relates to the one they specified in their original transfer.

Hive account@theycallmedan has said once the necessary infrastructure is in place he wouldn't mind providing liquidity in the form of ETH or HIVE to make everything work. There will need to be enough ETH available to process Hive transfers, and enough Hive available to process ETH transfers.

Hive account@lightproject might have more info on specifically what is required for Uniswap.
