Understanding Private Keys
A private key is a unique cryptographic code paired with a public key to enable secure encryption, decryption, and transaction signing. Derived from recovery phrases (seed phrases), private keys grant full control over a blockchain address, including the ability to:
- Send and receive cryptocurrency.
- Authorize transactions.
- Prove ownership of the linked public address.
Important: Possessing a private key equates to owning the associated wallet—keep it secure at all times.

Security Risks and Precautions
Critical Warning:
- An exposed private key compromises your wallet’s security immediately.

Action Required:
- If your private key or recovery phrase is leaked, transfer funds to a new wallet immediately and discontinue use of the compromised address.
FAQs
1. Can I import a multi-coin wallet using a private key?
No. Private key imports are limited to single-chain wallets (e.g., Ethereum-only).
2. What if I lose my private key?
Without a backup (e.g., recovery phrase), funds become irrecoverable. Always store keys offline securely.
3. Is private key import safer than recovery phrases?
No. Recovery phrases are preferable—they generate multiple keys and are easier to back up.
