# saddress

`saddress` 변수는 모든 주소 연산자를 지원합니다. 멤버로는 `call`, `delegatecall`, `staticcall`, `code`, `codehash`만 지원하며, `saddress payable`은 지원하지 않습니다.

[기본](/seismic-docs-kr/undefined-3/undefined.md)에서 설명된 보편적인 형변환 규칙과 제한 사항이 적용됩니다.

```solidity
saddress a = saddress(0x123);
saddress b = saddress(0x456);

// == 유효한 예시
a == b  // false
b.call()

// == 유효하지 않은 예시
a.balance
payable(a)
```
