checksumEthereumAddress(value): string | undefined

An Ethereum account (0x plus 40 hex digits, or the 40 digits alone) as 0x plus its EIP-55 checksummed digits, or undefined for anything else: another length or character, or a mixed-case spelling whose casing is not the EIP-55 one (a typo EIP-55 exists to catch). Byte-identical to ethers' getAddress for every value it accepts.
