   A fintech app wants to let users provide liquidity to a DeFi pool. The target users are not familiar with blockchain. Which UX approach best balances simplicity with the need for user control and transparency?

   • AShow users a simple 'Earn yield' button that automatically selects the highest-yield pool without showing details.
   • BRequire users to read and sign a full smart contract audit report before every transaction.
   • CLet users manually enter the pool contract address and approve the transaction via a browser wallet.
   • DProvide a one-click 'Deposit' action that uses a pre-audited pool, with a plain-language summary of risks and a confirmation step showing the estimated APY and lock-up terms.

   A fintech platform integrates a DeFi protocol that uses a price oracle. The oracle is compromised and reports a manipulated price, causing the platform's smart contract to execute unfair liquidations. The platform has a governance token that can vote on protocol parameters. Which response is most effective in mitigating the immediate impact?

   • AUse the governance token to propose and vote on a pause of the protocol's liquidation function until the oracle is fixed.
   • BSwitch to a different oracle provider without pausing the protocol.
   • CAsk users to manually close their positions to avoid liquidation.
   • DImmediately sell all platform-held governance tokens to avoid further losses.

   A fintech platform integrates a DeFi lending protocol to automate collateral liquidation. The integration relies on a price oracle. During a market flash crash, the oracle reports a stale price, causing unnecessary liquidations of user positions. Which mitigation is most effective?

   • AImplement a circuit breaker in the smart contract that pauses liquidations if the oracle price deviates from a secondary source by more than a threshold.
   • BRemove the oracle and use the last traded price from the fintech's own exchange.
   • CUse a single centralized oracle that the fintech fully controls to ensure price accuracy.
   • DIncrease the liquidation threshold so that liquidations only occur at extreme price moves.

   A fintech platform is offering a DeFi savings product that automatically rebalances user funds between a stablecoin lending pool and an automated market maker (AMM) liquidity pool to maximize yield. The platform's risk team is concerned about impermanent loss and smart contract risk. Which strategy best mitigates these risks while still offering a competitive yield?

   • ALimit the allocation to the AMM pool to a small percentage of the user's portfolio and set a maximum acceptable impermanent loss threshold that triggers a rebalance back to the lending pool.
   • BAllocate 100% of user funds to the AMM pool because it historically offers higher yields than lending.
   • COnly use the lending pool and avoid AMM pools entirely to eliminate impermanent loss risk.
   • DUse a smart contract that automatically moves funds to the AMM pool only when the market is trending upward, based on a price oracle.
