Dev utils

Dev utils to be shared across 0x projects and packages

Configuration

Some env variables might be set to change the behaviour of created web3 providers/instances.

VERBOSE_GANACHE: boolean. Enables verbose Ganache logging. Every request/response payload. Slightly slower, but useful for testing.
SOLIDITY_COVERAGE: boolean. If set - adds coverage subprovider which intercepts all calls/transactions and can be later used to compute code coverage.

Boolean env variables should be either true or false. Defaults to false if not set.
