Crypto borrowing platforms are transforming access to liquidity by leveraging blockchain technology. Unlike traditional lending systems, these platforms offer decentralized, borderless borrowing options, enabling users to unlock their crypto assets' value without selling them. Aave, a leading decentralized finance (DeFi) protocol, provides the infrastructure to build secure, transparent, and efficient lending platforms.
The digital lending market is projected to grow from $10.7 billion in 2021 to $20.5 billion by 2026, driven by increasing DeFi adoption. This guide explores the steps to create a crypto-borrowing platform using Aave, along with actionable tips for success.
How the Aave Protocol Works
Aave connects lenders and borrowers directly via smart contracts, eliminating intermediaries. Key components include:
Liquidity Pools
- Lenders deposit cryptocurrencies into pools, earning interest via aTokens (pegged to underlying assets).
- Borrowers access loans by over-collateralizing (typically at an 80% loan-to-value ratio).
Core Mechanics
- Depositing Funds: Users deposit crypto (e.g., 10 USDC → 10 aUSDC) to earn interest.
- Borrowing: Collateral must exceed the loan value. Liquidation occurs if collateral value drops critically.
- Dynamic Interest Rates: Adjust based on pool supply/demand.
- Smart Contracts: Govern all transactions, ensuring transparency and automation.
Tokenomics
- AAVE Token: Used for governance voting, staking rewards, and acting as a liquidity reserve.
