New to DeFi? This guide explains what DeFi wallets are, how they work, and how to choose the right one for interacting with decentralized finance.

What Is a DeFi Wallet?

A DeFi (Decentralized Finance) wallet is a crypto wallet that lets you:

Store cryptocurrency
Connect to DeFi applications
Swap tokens on DEXs
Lend/borrow crypto
Provide liquidity
Stake tokens

Key Difference from Exchange Wallets

Trezor Model T: Open source, secure

MetaMask: The DeFi Standard
