DeFi

Decentralized finance, or DeFi, uses blockchain applications to provide services such as swapping tokens, lending, borrowing and supplying liquidity. A wallet interacts with smart contracts that hold assets and apply the protocol’s rules.

What are DeFi tokens?

Browse the buying guides

Access can be open, although websites, asset issuers and individual products may impose restrictions. DeFi describes the service, not a guarantee that every part of it is decentralized.

How it works

Tokens can represent a vote, a deposit, a debt position or a claim on a pool of assets. These roles are not interchangeable. A governance token may have no right to protocol revenue, while a liquidity-pool token exposes its holder to the assets and pricing of that pool. Returns can come from borrower interest, trading fees or newly issued incentives; unusually high rewards need a clear explanation. Smart-contract failures, price-oracle errors, liquidation and bridge dependencies can all affect a position.

Cryptocurrency wallet and keys illustrating secure access and recovery

A little groundwork goes a long way

Before your next purchase or transfer, understand who controls access, where your crypto is going and what the trade will actually cost.

Protect access to your crypto

An exchange account and a self-custody wallet need different safeguards. Protect exchange logins with a unique password and strong two-factor authentication. For self-custody, your recovery backup is what lets you restore access.

Keep recovery words offline and private. A support agent or website asking for them is a reason to stop.

See a recovery example

Your phone breaks. An exchange may help you recover your account after identity checks. A self-custody wallet cannot reset your recovery phrase. Check your wallet’s official backup instructions before relying on it.

Choose the right transfer network

The asset, token version and network must be supported at the destination. A familiar ticker or a matching address format is not enough. Read the receiving platform’s deposit instructions before selecting a withdrawal network.

Check the address, any required memo or tag, fees and minimums. Consider a small test transfer first.

See a network example

Your destination accepts USDC on Ethereum. Selecting a cheaper network at the sending exchange does not make it an Ethereum transfer. Use a network both ends support; an ordinary withdrawal does not bridge tokens.

Understand the price you pay

Trading fees are only part of the cost. The spread, available liquidity and withdrawal charges also matter. A market order prioritizes execution; a limit order controls the price but may remain unfilled or fill only partly.

Check the order preview and the amount you will receive, then compare the full cost of your intended purchase and withdrawal.

Work through a cost example

Hypothetical example: a $200 trade with a 0.1% trading fee costs $0.20 in trading fees. A separate $5 withdrawal fee brings those charges to $5.20. Spread or slippage may add more; these are not quoted exchange rates.
