This PR #1257 introduced a regression that make the client not compatible with old runtimes.
Old runtimes doesn't check properly non transactional evm calls, old runtimes rely on the fact that max_fee_per_gas is None to consider the evm call non transactional.
It introduced a bug in Moonbeam where eth_call against past blocks produce the
BalanceLow
error.Because we can't change old runtimes, the client should not set
max_fee_per_gas
asSome(zero)
, otherwize old runtimes will assume that the evm call is transactional.
