Yield Farming
Yield farming is the use of crypto assets in decentralized-finance protocols to seek returns from lending, trading fees, token incentives, or liquidity provision. It can introduce smart-contract, market, liquidity, oracle, governance, and counterparty risks.
How It Works
Yield farming generally involves depositing tokens into protocols that use them for lending, market making, staking, or liquidity provision. Returns may come from borrower interest, trading fees, newly issued tokens, or temporary incentives intended to attract liquidity.
The advertised rate does not by itself explain the source or durability of the return. Token prices can fall, incentive programs can change, liquidity can disappear, and transaction costs can exceed the amount earned. A position may also depend on several protocols at once, so a failure in one contract, oracle, bridge, stablecoin, or collateral market can affect the entire strategy.
Wallet-key control is not the same as control over deposited assets. A user can sign a transaction from a self-custodied wallet and still transfer authority to a vulnerable or malicious smart contract. Before interacting with a protocol, a user would need to understand the approvals granted, withdrawal conditions, contract dependencies, liquidation rules, fee structure, and tax treatment. Even a careful review cannot eliminate these risks.
Key Points
- Seeks returns from lending, trading fees, liquidity provision, staking, or token incentives
- Returns can change quickly and may depend on volatile token prices
- Smart contracts, approvals, oracles, governance, stablecoins, and market liquidity add separate failure modes
- Holding the wallet key does not eliminate risks created by a deposit contract
- High advertised returns do not guarantee profit or return of principal
