Yield Aggregator

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

1. Protocol Scanning: Continuously monitors yield rates across protocols
2. Risk Analysis: Scores each opportunity based on TVL, audit status, and historical performance
3. Allocation: Distributes funds based on risk-adjusted returns
4. 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.
