# Gas Killer Smart Contracts

Source: https://gaskiller.xyz/#how-it-works

Why Cheaper execution Up to 99% gas savings, verified by aggregate signature. Safer contracts Room for the checks and invariants that gas costs rule out. Simple integration No new languages. No rearchitecting your smart contract. Services Turn gas savings into composable services. The surplus Gas Killer creates isn't just a cost reduction. It's programmable economic primitives you can route into your protocol. Gas Save Direct cost reduction applied automatically to every transaction. Gas Rebate Return a portion of savings to end users, improving retention and loyalty. Gas Buyback Channel surplus into protocol token buybacks for constant demand pressure. Gas Expand Run transactions that exceed the block gas limit while staying verifiable. Case study · RAILGUN Privacy on Ethereum at half the cost. RAILGUN uses zk-SNARKs for shielded transactions on Ethereum: powerful, but expensive for everyday users. We ran Gas Killer against 400 historical RAILGUN transactions from October 2025. Average Gas Killer savings for RAILGUN Read the full post Gas Analyzer Could your protocol save gas? Paste a transaction your contract has already processed. The Gas Analyzer replays it and shows what it would have cost through Gas Killer. It's the same analysis we ran for RAILGUN. STEP 01 Paste a transaction hash Any transaction your contract has already processed on Ethereum or Sepolia. STEP 02 Replay it The analyzer traces the transaction and works out the state changes it made. STEP 03 See the savings Original gas next to the Gas Killer cost, so you know if integrating is worth it. Updates Follow our progress. Research, benchmarks and release notes from the Gas Killer team.

ETHDenver 2025 First Prize: Best EigenLayer AVS

**timdaub.eth**: Not excited about this, sorry. can we pls fix Ethereum instead of launching a shitcoin to overload it
