I’m playing with the idea of cold storage that might be recovered by somebody who isn’t me. I want to store it in a durable way (cryptosteel or similar), but I’d like to also store a message along with it. Rather than buying a second cryptosteel for the message, I’d rather store it on the blockchain and associate it with the stored wallet.
My first thought was to enclose the message in the amounts of the first several transactions on the wallet, but that might be a bit over-engineered if I can somehow inject arbitrary data into the blockchain.
I’ve heard of this kind of thing on other platforms, but I’m having trouble finding anything about it for Cardano. Can I store messages on the blockchain associated with a wallet somehow?
