FUNCTION

# strategy

```signature
@extendable function strategy(): map<text, _strategy>
```

[Source](https://gitlab.com/chromaway/ft4-lib/-/blob/development/rell/src/lib/ft4/core/accounts/strategies/module.rell#lines-68)

Returns a map of all possible strategies used to register accounts on this chain.
Can be extended to add custom strategies and make them work seamlessly with the existing
`register_account` framework.

The map pairs up a strategy operation mount name and the `_strategy` struct representing it.
The name must be the mount name of `_strategy.op`

To avoid misconfiguring strategies, it is strongly recommended to add extensions to this
function using `add_strategy`.

Throws if any extension of this function throws.
