THE PROBLEM

What needed solving

1

DeFi users were tracking positions across 10+ protocols and 3+ chains using separate interfaces and spreadsheets.

2

Yield farming opportunities were missed because users couldn't compare APYs across protocols in real-time.

3

Gas fee estimation was unreliable, leading to failed transactions and wasted funds.

4

No unified view existed for total portfolio value, impermanent loss tracking, or historical performance.

THE SOLUTION

How I approached it

Built a multi-chain aggregation layer using The Graph that indexes positions across Ethereum, Polygon, and Arbitrum.

Created a real-time yield comparison engine that normalizes APYs and factors in gas costs for true ROI calculation.

Implemented smart gas estimation with automatic retry and MEV protection for swaps.

Designed a portfolio analytics dashboard with P&L tracking, impermanent loss alerts, and tax-ready export.
