Yield Aggregator
A DeFi yield aggregation platform built with TypeScript, helping users maximize returns across multiple protocols.
Overview
A decentralized finance (DeFi) yield aggregator that automatically finds and allocates funds to the highest-yielding opportunities across multiple protocols. Built with TypeScript for type safety and better developer experience.
Key Features
- Multi-Protocol Support: Integrates with various DeFi protocols
- Auto-Compounding: Automatically reinvests yields
- Risk Assessment: Evaluates protocol risks before allocation
- Gas Optimization: Batches transactions to minimize costs
Technical Stack
- Language: TypeScript
- Blockchain Interaction: ethers.js / web3.js
- Smart Contracts: Solidity
- Testing: Hardhat, Mocha
Architecture
interface YieldStrategy {
protocol: string;
apy: number;
riskScore: number;
tvl: bigint;
deposit(amount: bigint): Promise<TransactionReceipt>;
withdraw(amount: bigint): Promise<TransactionReceipt>;
harvest(): Promise<bigint>;
}
How It Works
- Protocol Scanning: Continuously monitors yield rates across protocols
- Risk Analysis: Scores each opportunity based on TVL, audit status, and historical performance
- Allocation: Distributes funds based on risk-adjusted returns
- Auto-Compound: Harvests and reinvests rewards at optimal intervals
Challenges Solved
- Impermanent Loss Calculation: Accurate IL tracking for LP positions
- Gas Estimation: Predictive gas pricing for optimal transaction timing
- MEV Protection: Strategies to minimize front-running risks
Results
The aggregator has been tested to achieve higher yields compared to single-protocol staking while maintaining acceptable risk levels through diversification.
