1Balancer - Automated Portfolio Rebalancing

ETH Rome 2025 - Finance Track Submission

An intelligent DeFi portfolio management system that automatically rebalances WETH and USDC holdings to maintain a 50/50 allocation. Built on Base with advanced Web3 integrations and iExec confidential computing capabilities.

🎯 Project Overview

1Balancer is a non-custodial portfolio management platform that eliminates emotional trading decisions through automated rebalancing. Our system continuously monitors your WETH and USDC holdings and executes trades to maintain optimal 50/50 allocation, selling when prices rise and buying when they fall.

Core Strategy

"Our portfolio keeps your WETH and USDC at 50/50, selling when prices rise and buying when they fall. No emotions, no stress—just smart rebalancing."
