What I did
Add
gas_buffer
to transactions, a multiplier applied toeth_estimateGas
when determining the gas limit for a transaction.Closes #725
How I did it
gas_buffer
is a valid kwarg foraccount.transfer
or value in a contract call transaction dictionary.main.gas_buffer()
may be used to modify the default settinggas_buffer
may be included in the configuration settingsYou cannot provide both
gas_buffer
andgas_limit
at the same time, doing so raises aValueError
.How to verify it
Run the tests. I added some new test cases around the behaviour.
