Today, we're excited to announce Gas Killer, a breakthrough approach to scaling computation on Ethereum that makes gas expensive smart contract operations dramatically cheaper with only one line of code. Gas Killer was originally developed by Ron Turetzky and the Bread Cooperative team at the ETH Denver hackathon in February 2025.

Ethereum's gas costs have created a fundamental barrier: complex computations that involve multiple storage reads, calculations, and state updates are prohibitively expensive for mass adoption.

Simple operations that are negligibly cheap on a single computer like computations on a dynamic array are too expensive to do on the Ethereum mainnet. Layer 2 EVM blockchains have helped with scaling however they have also produced a fragmented ecosystem and capital, making it difficult to onboard new users. It has also pushed value away from the Ethereum L1, the original blockchain that brought many of us together in the first place.  

For many use cases, the cost of computation has made otherwise valuable applications economically unviable. This limitation in computation affects everyone. From privacy protocols requiring heavy cryptographic operations to applications needing complex on-chain logic, on-chain computation must scale in Ethereum.

This is where Gas Killer comes in.

Gas Killer is an Actively Validated Service (AVS) built on EigenCloud that transforms how we think about on-chain computation. Instead of executing expensive calculations directly on Ethereum, Gas Killer uses a network of operators to simulate transactions off-chain and write back only the essential storage updates and external calls.

The core innovation is simple but powerful: replace complex on-chain operations with aggregate signature verification. When a transaction comes in, Gas Killer's operators execute the logic off-chain, compute the final state changes, and return an aggregate signature proving the computation was performed correctly. The smart contract then verifies this signature and applies the storage updates and external calls—consuming a fraction of the original gas cost.

The important caveat is that Gas Killer is able to save gas specifically on all internal reads (reading from within a contract’s own storage or memory during execution), some external reads (calling another contract to fetch data) and computation (arithmetic, logic, or cryptographic operations inside the EVM). So any storage writes needed will still need to be paid for through gas fees. Additionally the aggregate signature verification will also incur a cost every time Gas Killer is used.

Taking the implications of Gas Killer adoption to its conclusion, it implies the existence of what we call the Turetzky Upper Gas Limit (TUGL), or that on any deterministic blockchain, any function with internal reads and calculations above the cost of aggregate signature verification can be reduced to just that verification cost plus necessary storage writes. In other words, no matter how complex your computation, Gas Killer can bring it down to a theoretical minimum.

The best part about all this is that in order to use Gas Killer for their method, developers will only need to add a single line of code. No reworking of any smart contract logic, no need to learn a new programming language, no other changes need to be made and you and your users can save on gas fees.

This means at least two very big things.

1. Smart contract developers do not need to do nearly as much gas optimizations as what is the norm today. Instead of optimizing for gas costs, developers can now optimize for other things like security or expressiveness. This also means we can do calculations on dynamic arrays! 

2. We can now run methods that go beyond the block gas limit. No matter how complex the computation, even if it’s more gas than is technically allowed in a block, Gas Killer can run it. Of course the exact extent of how far this can go needs to be tested but it should be ok if it can be run on a single computer.

We believe Gas Killer is just the start of a Cambrian explosion of new use cases and applications that it can enable. Some of the areas where we’ve already found Gas Killer to be a potential scaler includes:

• Voting mechanisms

• Privacy

• ZK Proof verification 

• Deep Infrastructure 

• On-chain Art

• Token Rebasing

• On-chain AI

• Airdrops

• Slow DeFi

• Gaming

And we’re excited to see everything else that others will be able to build now with Gas Killer that we can’t even imagine at this point in time.

We're proud to share that Gas Killer v1.0 is now released and soon will be operational on testnet, Ethereum mainnet and Gnosis Chain. If your organization is dealing with high gas costs and wants to explore whether Gas Killer can optimize your smart contracts, we want to hear from you. We're actively working with early partners to test integrations and demonstrate real-world gas savings.

Whether you're building privacy infrastructure, complex financial protocols, or any application where gas costs are a barrier, Gas Killer could fundamentally change your economics. Fill out our form and our team will reach out to discuss how we can help optimize your contracts.

Over the next three months, we'll be conducting comprehensive research on Gas Killer's impact across different use cases, measuring exact gas savings, and working with partners to prove the real-world benefits. Our goal is simple: to super scale Ethereum computation.

The future of Ethereum isn't just about scaling transactions—it's about scaling computation. Gas Killer is here to make that happen.
