Gas Killer
Gas Killer
Secure contracts shouldn't cost more.
Cheaper, safer smart contracts without rewriting them.
Is your protocol overpaying for gas?Find outWhy
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.
How
Off‑chain execution. On‑chain security.
Operators verifiably simulate transactions off-chain and write back only the essential state changes, compressing expensive computation into a single signature verification on-chain.
Upgrade your contract
Add a single line of Solidity. No new languages, no rearchitecting, no application-specific rewrites.
Redirect to the RPC
Point transactions at the Gas Killer RPC. Execution moves off-chain; only the final state update lands on-chain, verified by an aggregate signature.
If the network is unavailable, transactions fall back to executing on-chain. Gas Killer is never a bottleneck. Operators returning incorrect outputs are rejected and slashed.
Live demos
Try it on Sepolia.
Both demos settle through Gas Killer's operators on Sepolia. Each one shows the gas it used next to what the same transaction costs without Gas Killer.
Heavy computation
The Game of Life
One generation of Conway's Game of Life costs 16.6M gas as a normal transaction. Gas Killer settles it for under 1% of that, and runs two generations that no single transaction could hold.
Zero-knowledge proofs
Private ETH payments
Every private payment carries a zero-knowledge proof, and checking it on chain costs 640–860k gas. Gas Killer checks it off chain, so shields, sends, withdrawals and take-ins cost 26–38% less, with the same privacy.
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.
Proven savings
Where Gas Killer cuts gas.
Estimated gas savings from running each protocol's most expensive functions through Gas Killer. They cover privacy, bridging, lending, derivatives and real-world assets.

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.
- 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.
