You need to connect your XUMM wallet before creating events

You must scan a qrcode with your wallet and accept the request

We use XUMM as our preferred crypto wallet

In order to mint NFTs you will need to install XUMM wallet in your mobile phone and have some XRP funds as all transactions will be stored in Ripple blockchain

Once installed, scan the qrcode to add NFT-DEVNET to XUMM wallet as NFTs in Ripple are in beta for the moment

Then go to the faucet to get some test coins to start minting some NFTs, remember to use NFT-DEVNET again
