Thanks for reaching out - Can you provide a little more information? What browser are you using? If you try this on desktop are you seeing the same error?
We checked your wallet — you’re just barely short on ETH to cover the mint cost plus gas fees for 10 mints. You’ll need about 0.0124 ETH total and your balance is right at that line. A bit more ETH should do it!
We’re also improving our error messaging to make situations like this clearer instead of showing a generic “Transaction Failed.”
Let us know if you hit any other issues!
And thank you for the report on the broken Contact Support button — we’re fixing that too
