By sending a message, you create an NFT that shows the text of your message. You can only use certain characters (all letters and numbers, some special characters - ASCII standard). Any interaction (sending messages, up/downvoting, setting a username etc.) should open your Metamask and ask you to confirm. Once the transaction is confirmed, the message (we call it a "purr") is displayed here on purry.io. If Metamask is not prompted, you may have used too many or non-supported characters. You can click on any message to see replies. If your "purr" receives too many dislikes, it may fade away!

If you are new to Metamask: Install the Metamask extension in your browser and add the Avalanche Fuji Testnet, e.g. by going to chainlist.org: click "Connect Wallet", switch on the toggle "Testnets" and search for Fuji. Get test AVAX for free from a faucet. Once you have Test AVAX you can start using Purry by clicking "Connect Wallet".
