3. Energiswap App
After adding the custom Energi Mainnet network, it’s possible that you might still see your fees being calculated in “ETH”, as well as the Ethereum Icon (
) instead of NRG (
). The reason this happens is due to MetaMask automatically pulling data for Ethereum by default. You do not need to worry about spending any ETH you might have, as long as you make sure to be connected to the Energi Mainnet network as instructed by the previous steps. We have already reached out to MetaMask to include native support for NRG.

Leave some NRG in your wallet to cover gas fees. You may need to create a new pair if the pair you want to add liquidity to does not exist yet. You can choose the amounts of assets you want to provide and this will determine the initial price of the pair.
