This error indicates that an invalid address was passed to one of the
contract instance decoder spawners (forContractInstance, etc). Valid
addresses are those that Web3 accepts; i.e., either those with correct
checksums, or those that are all-lowercase or all-uppercase to deliberately
circumvent the checksum.
