What are self-destructing coins?

Self-destructing coins are special coins that disappear after you use them once.

Imagine you have a piggy bank full of regular coins, they stay there forever. But self-destructing coins are like those special candies your friend gives you at the park: once you eat one, it’s gone! That’s what happens with these coins, when you spend them, poof, they vanish.

Think of a vending machine that only takes these special coins. You put in a coin, get your favorite snack, and then whoosh, the coin is gone. It didn’t go anywhere; it just stopped existing after you used it once. That’s why we call them self-destructing.

Sometimes people use self-destructing coins to keep secrets or surprise others. If someone sends you a message using one of these coins, the coin disappears after you read it, like a little magic trick without any actual magic! It's like having a special toy that only works once, and then it turns into dust.
