A DeFi protocol wants to offer a stablecoin that is backed by a basket of crypto assets. The team is concerned about the risk of a de-pegging event. They want to design a mechanism that maintains the peg even during market volatility. Which approach is most robust?

Use a fiat-collateralized stablecoin but with a decentralized custodian

Use an algorithmic stablecoin that adjusts supply based on market demand

Use a commodity-collateralized stablecoin backed by gold

Use a crypto-collateralized stablecoin with overcollateralization and a liquidation mechanism

A DeFi protocol is designed to automatically liquidate undercollateralized loans. The smart contract must trigger liquidation when the collateral value falls below a threshold. Which component is necessary to enable this automation?

A stablecoin that is used as the collateral.

A decentralized exchange (DEX) to swap collateral.

A price oracle that provides real-time collateral value to the smart contract.

A governance token that allows users to vote on liquidation thresholds.

A developer is writing a smart contract for a decentralized exchange (DEX) that allows users to swap tokens. The contract must ensure that users cannot withdraw more tokens than they deposited. Which smart contract feature is essential to enforce this?

A governance token that allows users to vote on withdrawal limits.

An oracle that provides real-time token prices.

A balance tracking mechanism that updates user balances only after successful transfers.

A time-lock that delays all withdrawals by 24 hours.

What is the primary purpose of a governance token in a DeFi protocol?

To grant holders voting rights on protocol decisions

To provide a stable store of value
