# params

Params module allows you to query the system parameters which can be governed (except the gov params) by the gov module.

```Bash
uptickd query params subspace [subspace] [key] [flags]
```

Subspace currently supports the following:`auth`, `bank`, `staking`, `mint`, `distribution`, `slashing`, `gov`, `crisis`, `token`, `record`, `htlc`, `coinswap`, `service`.Among them, the parameters available for query for each subspace are as follows:
