Notes

Two entries were duplicated in the source list (eth_createAccessList, eth_fillTransaction) and are represented once in this matrix.
Some methods marked as supported may still return empty or null values depending on state, filter lifecycle, or query context.
Revalidate behavior against your deployment before production rollout.
