Now that is vanity wallet if I’ve ever seen one. I did this once for a keypair to 1combo…it has 0.0028xxxx bitcoin on it to this day…and it’s my locker combination. I still have the lock, but not the private key.
Yo, where my nerds at?!!
I created a bitcoin mnemonic that starts with "coffee".
Its fingerprint is c0ffee4b
It has a receive address that starts with 3Coffee
That address wrote an OP_RETURN that says "c0ffee inception!"
And the txid of that transaction starts with... c0ffee!!!

Thankfully, it looks like I only used free sats to put my combination on the blockchain for ever. Back in the day, you could view an advertisement in exchange for a tiny amount of money…like 0.01 bitcoins.
