## DeFi Protocol

A DeFi protocol is a set of smart contracts that automate financial services on a blockchain, such as lending, borrowing, and trading. These protocols operate without central intermediaries, relying instead on code to execute transactions and manage assets.

They are designed to be transparent, permissionless, and interoperable, allowing anyone with a digital wallet to access financial tools. Value accrual in these protocols is often driven by governance tokens that allow holders to vote on protocol upgrades and economic parameters.

However, they also introduce unique risks, including smart contract bugs, flash loan attacks, and regulatory uncertainty. Understanding the underlying code and incentive structures is essential for assessing the safety and potential of any DeFi protocol.
