Write your seed phrase in invisible ink on an ordinary object, like a family photo, your favorite book, or a printed document.
To anyone else, it’s nothing. Only you know where, and how to look.

First, generate a random order of the numbers 1 through 24. Write this sequence in invisible ink—one number per line. Once it dries, write your seed words next to each number in plain ink.
It’s clearly a seed phrase—but without the hidden order, it’s useless.

Only you know how to put it back together.

Write your real seed phrase in invisible ink. Let it dry. Then, write a second seed phrase on top in visible ink, one that leads to a low-value wallet.

If that wallet is ever accessed, you’ll know the paper was compromised, and its time to move the real funds.
