What Is a Private Key?
A private key is the secret code that proves you own your crypto and lets you spend it. Whoever holds
it controls the funds.
1
Proves ownership
It signs transactions to spend from your wallet.
2
Never share it
Anyone with your key can take everything, instantly.
3
Not your keys
Not your keys, not your coins, the core rule of self-custody.
