#### ADD object
##### ExecutorID
- **Type**: object  
  **Required**  
  Identifies an on-chain address in transaction intents and related APIs. Either set both `MasterKeyName` and `AccountName` (with optional `AddressIndex` where the API allows it; index `0` is the main address when deriving), or set `Address` to a literal address string. Setting only one of `MasterKeyName` or `AccountName` is invalid.

**For** [`POST /solana/accountInfo`](https://vault.docs.blockdaemon.com/reference/cwpstartcreateallocation#/paths/~1solana~1accountInfo/post), when not sending `Address`, `AddressIndex` is required alongside master key and account.
