You Won’t Believe What Bitcoin Just Got Wrapped Into!
Now, Bitcoin itself is a simple sort, not one for smart contracts or other highfalutin antics. You can’t just hand it over to Ethereum-based DeFi apps like you’re passing a hot potato. Enter “wrapped” tokens-because apparently, Bitcoin needed a coat to be social.
cirBTC is Circle’s own attempt at this dress-up game. They promise to keep one real Bitcoin in the pantry for every cirBTC they hand out. That way, it supposedly stays pegged 1:1, though one has to squint a little to see if the mirror really shows what it claims.
