Very informative, just days after I applied for a grant to fund the minting my first NFT and have it promoted via exhibition. I am an artist/writer who has actually made digital art.
For grant app, had to get a wallet on Metamask and link it to the granting org similiar to what you described. Just found out I did not make the cut, but that they want to mint and promote the work of the nominees.
After reading how much this cost you, I'm worred now that part of this effort was to get non-winning nominees like me to spend bucks, err, ETH, or Gas or, jeez, am I too old for this?
