# Global DOM_SEP__SIGNATURE_PAYLOAD

Module: `noir_aztec::protocol::constants`

```rust
pub global DOM_SEP__SIGNATURE_PAYLOAD: u32;
```

Domain separator for account contract payloads.

Used to check for authorization to execute a payload.

This is not technically a protocol constant as payload authorization is an account contract feature.
