Our payment provider supports the Lighning Network.
So, if your wallet supports Lightning Network transactions, you can do so.
If not, we recommend using Phoenix, Breez or Muun wallet.
Alternatively, you can choose any wallet from this list of Lightning-enabled wallets.
We also have on our website an article on how you can use the Lightning network:
