I have a simple question if i use off chain workers to get calls to https://somecoinexchange/ to get data for some calculation, what will be the gas usage. I was presuming that since no chain work is done, no gas will be used.

1 Answer 1


FRAME doesn't use the concept of gas. It uses weight, which is currently determined based on running benchmarks on some standard hardware. However, everything that runs in offchain_worker doesn't use any weight at all. The runtime code itself is seen as trusted code, but nodes are still allowed to opt-out from running offchain_worker.

TDLR: Your assumption that no weight/gas is being used is correct.
