Public & Private Keys: What a Wallet Really Is
A wallet does not "hold" coins — it holds keys. The public key is like an account/address; the private key is the password and signing power. Whoever has the private key owns the coins.
The Key Pair
The private key is a secret number only you know; from it, the public key and your receiving address are mathematically derived. Others send to your address, but only the holder of the private key can spend those coins. Share the address freely; never reveal the private key.
The Seed Phrase Is Your Key Backup
The 12/24-word seed phrase is the human-readable form of your private key and can restore all your assets. Guarding the seed = guarding the funds. Write it offline by hand, never upload it, never tell anyone — the first rule of self-custody.
