- **DestinationAmounts**

  required

- **DestinationAmounts***  
    object  
    A single transfer destination with amount. Use Destination for vault name (internal) or address (external). MasterKeyName is required for internal transfers.

      required  
      Recipient vault name (internal) or blockchain address (external).

- **MasterKeyName**

- **ExecutorID**  
  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-1#/paths/~1solana~1accountInfo/post), when not sending `Address`, `AddressIndex` is required alongside master key and account.
