The idea,
in words.

Your Bitcoin wallet holds something more powerful than coins. It holds the keys that let you spend them.

Bitcoin stays on a shared public ledger: the blockchain. Your wallet reads that record to show what you can spend.

To receive bitcoin, share a receiving address from your wallet. Think of it as a destination, not your secret key.

To send, your wallet signs a transaction with a private key. The signature proves permission without revealing that key.

The network checks the transaction. Miners include valid transactions in blocks, and further blocks add confirmations.

With a typical self-custody wallet, a recovery phrase can restore your keys. Keep it offline and secret. Anyone with it can take your bitcoin.

An exchange may hold the keys for you. Self-custody puts you in control. The blockchain keeps the record. Your wallet gives you the keys.
