yearn.finance (YFI) is a popular decentralized finance (DeFi) protocol. To keep your YFI tokens secure, you need to understand and use cryptocurrency wallets properly. This guide breaks down wallet types and best practices for safe storage.
Holding YFI on an exchange means you don't control the private keys, which exposes you to exchange hacks or failures. Moving YFI to a wallet you control is the first step toward true self-custody. Your wallet choice determines your security level and how you interact with DeFi.
Hardware wallets (like Ledger or Trezor) are physical devices that store your private keys offline, making them highly secure against online attacks. Software wallets, including browser extensions (like MetaMask) and mobile apps, are free and convenient for frequent use but are more vulnerable to malware. For significant, long-term YFI holdings, a hardware wallet is the recommended standard.
Always purchase hardware wallets directly from the manufacturer to avoid tampering. Never share your seed phrase or private key with anyone; store your written recovery phrase in a secure, offline location like a fireproof safe. Use two-factor authentication (2FA) on exchange accounts, but understand that for true ownership, moving assets to your personal wallet is essential.

If you lose your seed phrase and your device fails, you will permanently lose access to your YFI and any other assets in that wallet. It is crucial to have a secure, backed-up copy of your recovery phrase.
Connecting to reputable DeFi applications is part of normal usage, but always verify you are on the correct website. Be cautious of phishing sites and only approve transactions you understand. Consider using a separate wallet with limited funds for frequent DeFi interactions.
