Portfolio Management Features

Loopify Finance provides sophisticated portfolio management capabilities enabling users to coordinate operations across multiple positions, automate rebalancing, and optimize capital allocation through intelligent batch processing and real-time monitoring. Our Portfolio Manager contract leverages the Absorb library for maximum gas efficiency across the entire DeFi ecosystem.

Portfolio Manager: Cross-System Operations​

Unified Portfolio Management with Absorb Integration​

The Portfolio Manager contract enables atomic operations across both Vault and Looping systems:

Gas Efficiency Through Cross-System Optimization​

Before Portfolio Manager:

  • 6 separate transactions across systems: ~270k gas

After Portfolio Manager with Absorb:

  • Single optimized transaction: ~85k gas
  • 68% gas reduction + improved UX

Multi-Position Batch Operations​
