Protocole DeFi

When working with protocole DeFi, un ensemble de smart contracts qui permettent de prêter, d'emprunter ou d'échanger des actifs sans intermédiaire. Also known as finance décentralisée, it reshapes how we use money on blockchain.

The protocole DeFi doesn't exist in a vacuum. It hinges on DAO, des organisations autonomes qui décident collectivement des règles du protocole. A DAO governs upgrades, fee structures and incentive programs, creating a transparent decision‑making layer. Because governance is on‑chain, anyone holding the governance token can propose or vote, which means the protocol evolves with its community.

Another pillar is yield farming, une stratégie qui consiste à bloquer des actifs dans un protocole pour gagner des récompenses. Yield farming drives capital into new projects, boosts liquidity, and offers users passive income. The higher the returns, the more users are attracted, which in turn strengthens the underlying liquidity pools.

Liquidity pools themselves are the engine that powers swaps and lending. They are collections of tokens supplied by users, and smart contracts manage the automated market maker (AMM) algorithm. When you trade, you interact directly with the pool, not with a counter‑party. This model reduces slippage and enables 24/7 trading.

Smart contracts are the technical substrate linking all these pieces. They execute pre‑programmed rules, enforce collateral ratios, and distribute rewards. A well‑audited contract lowers risk, while modular contracts allow developers to stack functionalities—think of a lending module built on top of an existing AMM.

Putting it together, a DeFi protocol encompasses governance (DAO), capital provision (liquidity pools), incentive mechanisms (yield farming) and the code that binds them (smart contracts). Each component influences the others: stronger governance can attract more liquidity, richer pools enable better yields, and robust contracts ensure safety.
