Crypto Lending Splits into CeFi and DeFi, with Risks and Rewards Aligned

Crypto lending has evolved into two distinct systems: centralized finance (CeFi) and decentralized finance (DeFi). CeFi platforms, such as Nexo and Binance, manage loans from start to finish, while DeFi platforms, like Aave, use smart contracts that automate the process. On April 18, 2026, a hacker drained $293 million from Kelp DAO's cross-chain bridge, exposing vulnerabilities in interconnected DeFi collateral.

Lenders earn interest on their deposited crypto, but rates fluctuate based on market demand, loan terms, and asset type. Stablecoins tend to pay steadier yields due to higher demand. Borrowing works by locking up more value than borrowed, with over-collateralization required to secure loans. However, liquidation can occur if the collateral's market value falls below a certain threshold.

The U.S. government is working on regulations for crypto lending, but no final rulebook has been established yet. Platforms like Aave and Nexo operate under different approaches, with Aave supporting multiple blockchain networks and Nexo offering crypto-backed credit lines alongside yield accounts.
