   A fintech platform integrates a DeFi lending protocol on Ethereum. During peak usage, users experience long transaction delays and high fees. The platform wants to improve throughput and reduce costs without changing the user-facing product. Which solution is most appropriate?

   • AIncrease the gas price for all transactions to prioritize them.
   • BSwitch to a different Layer 1 blockchain that is faster but has no bridge to Ethereum.
   • CMove all operations to a single high-performance server that batches transactions and submits them to Ethereum.
   • DUse a Layer 2 rollup that inherits Ethereum's security and offers higher throughput and lower fees, and integrate the platform with the rollup.

   A fintech platform is studying a case study of a failed DeFi integration. The platform had integrated a DeFi protocol without a clear regulatory assessment and later faced fines. The case study also shows that the platform did not have a fallback plan when the protocol's smart contract was exploited. Which combination of best practices would have most likely prevented this failure?

   • AUse a more popular DeFi protocol that is less likely to be exploited.
   • BIntegrate the protocol only after it has been operating for a year.
   • CConduct a regulatory assessment before integration and establish a contingency plan for smart contract failures.
   • DRely on the protocol's own insurance to cover any losses.

   A neobank wants to offer a 'DeFi savings' product where users earn yield from a liquidity pool. The product must be simple for retail users, and the bank must be able to report user balances for tax purposes. Which design choice best satisfies both requirements?

   • ACreate a separate smart contract for each user to hold their funds and generate yield individually.
   • BOffer the product only to users who sign a waiver acknowledging they will handle their own tax reporting.
   • CLet users connect their own wallets and interact directly with the pool, while the bank only displays an estimated yield.
   • DUse a pooled custodial model where the bank holds the assets and interacts with the pool via a smart contract, tracking each user's share off-chain.
