Warning: EIP-1191 checksum addresses are generally not backwards compatible with the
wider Ethereum ecosystem, meaning it will break when validated against an application/tool
that relies on EIP-55 checksum encoding (checksum without chainId).
It is highly recommended to not use this feature unless you
know what you are doing.
