What is Private Key?
A secret cryptographic key that gives you full control over your cryptocurrency wallet, used to sign transactions and prove ownership of your funds.
A private key is a secret string of characters that controls a cryptocurrency wallet. Anyone who has your private key has complete access to your funds — they can send tokens, sign transactions, and drain your wallet.
Private Keys on Solana
Solana private keys are typically represented as:
- •Base58 string — A long string of letters and numbers (exported from wallets like Phantom)
- •Byte array — A JSON array of 64 numbers (generated by solana-keygen)
Both formats represent the same key and can be used interchangeably.
