But for multi-chain smart contracts no assumptions should be made other than being UTF-8 encoded and of reasonable length.\n\nThis type represents a validated address. It can be created in the following ways 1. Use `Addr::unchecked(input)` 2. Use `let checked: Addr = deps.api.addr_validate(input)?` 3. Use `let checked: Addr = deps.api.addr_humanize(canonical_addr)?` 4. Deserialize from JSON. This must only be done from JSON that was validated before such as a contract's state. `Addr` must not be used in messages sent by the user because this would result in unvalidated instances.\n\nThis type is immutable.
