OPERATION

# ras\_open

```signature
@mount("ft4.ras_open")
operation ras_open(main: auth_descriptor, disposable: auth_descriptor?)
```

[Source](https://gitlab.com/chromaway/ft4-lib/-/blob/development/rell/src/lib/ft4/core/accounts/strategies/open/module.rell#lines-22)

The operation that defines the open strategy. The open strategy will allow anybody to
register an account by simply sending a transaction that uses it.
In most cases, this is not something that is desirable for production dapps, as it will
expose the dapp to spam account creation.

Throws if the next operation in the transaction is not accepted by
`require_register_account_next_operation`

**Parameters**

* **main** — the main auth descriptor for the account that will be registered
* **disposable** — optionally, the disposable auth descriptor for the same account

**See Also**

* `core.accounts.strategies._strategy` — for information on how to register an account using this strategy
