# Gas Killer

**Gas Killer** is an eco-friendly AVS that uses BLS signature verification to securely simulate transactions off-chain and write back storage slot updates, saving gas and reducing blockchain energy consumption.

It achieves this through:

- Securely simulating transactions off-chain using BLS signature verification
- Autogenerating functions for slashing, AVS access control, and contract storage tracking
- Allowing for unlimited array operations without gas limits

## Benefits

- Up to 99% gas savings
- Sustainable smart contracts for a greener blockchain
- Easy integration with existing smart contracts
- No more gas auditing or complex optimizations

## Key Features

- EigenLayer Validation for trustless computation verification
- Slashing Mechanism for security guarantees
- State Transition Management for consistent calculations
- Write smart contracts without gas constraints
