Address manipulation
Some Utils functions exist to make address manipulation easier:
toLowercaseAddress()converts the address to an all-lowercase format (e.g. "0xacbdef...").- t
oUppercaseAddress()converts the address to an all-uppercase format (e.g. "0XABCDEF..."). toChecksumAddress()converts the address to a mixed-case format, also known as "checksum", according to the EIP-55 specification (e.g. "0xaBcdEF...").isAddress()checks if a string is an address (size, format, and if the checksum is valid when in mixed-case).checkAddressChecksum()checks if the address checksum is correct.
Example:
Address addOri = Address("0x1a2b3c4d5e6f7e8d9c0b1a2b3c4d5e6f7e8d9c0b", true);
Hex addUpp = addOri.toUppercaseAddress(addOri);
Hex addLow = addOri.toLowercaseAddress(addUpp);
Hex addChk = addOri.toChecksumAddress(addOri);
std::string << addOri << std::endl;
std::string << addUpp << std::endl;
std::string << addLow << std::endl;
std::string << addChk << std::endl;
std::string << Utils::isAddress(addChk.get()) << std::endl;
std::string << Utils::isChksum(addChk) << std::endl;
There's no "default" behavior here, but it's ideal to always have addresses in lower case and convert them to other types when required.
