Accepts 0x plus 40 hex digits and eth| plus 40 hex digits; the caller's casing is kept. eth|0x... is not an address form and is refused. For LazyPrivateKeySignerOptions.expectedAddress, which should only be set for an account whose key can be checked.

Example

createLazyPrivateKeySigner(getKey, { expectedAddress: ethereumAddressOfAccount(account) });
