Gas Profiling

Methodology


Solc version: 0.8.14	Optimizer enabled: true	Runs: 1000
Block limit: 30000000 gas	25 gwei/gas	13.44 usd/avax

Spanning Requests don't change any state on the blockchain. Most of the gas cost of a Spanning Request is determined based on the size of the request payload that must be written to the SpanningRequest event log.
