How does yield farming typically generate returns for users?

By combining multiple DeFi strategies, such as providing liquidity and staking LP tokens, to earn trading fees and additional token rewards.

By validating transactions on a proof-of-stake network.

By purchasing tokens at an initial coin offering and selling them later at a higher price.

By holding a fixed amount of a stablecoin in a wallet and receiving daily interest.

A DEX operator is designing a new AMM pool for a token that has no established market price. They are concerned about both initial price discovery and manipulation resistance. They decide to use a constant product formula. What additional mechanism should they implement to reduce the risk of price manipulation during the pool's early days?

Use a constant sum formula instead to keep the price fixed

Disable trading for the first 24 hours after launch

Use a time-weighted average price (TWAP) oracle for the pool's own price feed

Set the initial price based on the team's private valuation of the token

What is the primary function of staking in a proof-of-stake blockchain?

To store tokens in a cold wallet for safekeeping.

To lend tokens to borrowers and earn interest.

To provide liquidity to a decentralized exchange and earn trading fees.

To lock up tokens as collateral to secure the network and participate in consensus.

A DeFi protocol is launching a liquidity mining program. The team wants to maximize the longevity of the incentive program while avoiding a 'dump' of the governance token. Which strategy is most effective?

Offer rewards only to large institutional liquidity providers

Distribute all rewards upfront to attract maximum liquidity quickly

Set the reward rate to zero after the first month

Vest the mining rewards over time and allow staking of the governance token to earn a share of protocol fees

A DeFi protocol's DAO is considering a proposal to change the fee structure. The proposal is controversial, and the team is concerned about a governance attack. Which mechanism would best protect the protocol from a malicious proposal?

Increase the quorum requirement to 100% of all token holders

Implement a timelock on all governance actions and require a supermajority vote for critical parameter changes

Remove the governance token and rely on a multisig wallet

Allow the core team to veto any proposal they disagree with
