Gas Killer could cut the gas cost of the Axelar Gateway's execute by 22–37%, about 92,000–107,000 gas on each call. Each execute approves a batch of cross-chain messages after checking validator signatures. We measured this on real Ethereum mainnet calls in October 2026. The Gateway received 137 execute calls in one day.
