In order to provide liquidity, you'll first have to purchase either BOMB or BSHARE (have a look at our "How to Buy BOMB" section if you need help in doing so), depending on which you want to provide liquidity for.
Providing liquidity is possible on PancakeSwap. Head over to the Liquidity tab on the left side of your screen. Connect your wallet (make sure your Metamask is on the BSC Network). Now you have to choose the tokens you wish to add liquidity with. For the first, select BTCB or BNB. For the second, choose either BOMB or BSHARE, respectively.
If BOMB or BSHARE do not show up, please manually copy/paste the address as shown below.
