## CLI

A user can query and interact with the `bank` module using the CLI.

### Query

The `query` commands allow users to query `bank` state.

```sh
simd query bank --help
```

#### balances

The `balances` command allows users to query account balances by address.

```sh
simd query bank balances [address] [flags]
```

Example:

```sh
simd query bank balances cosmos1..
```

Example Output:

```yml
balances:
- amount: "1000000000"
  denom: stake
pagination:
  next_key: null
  total: "0"
```

#### denom-metadata

The `denom-metadata` command allows users to query metadata for coin denominations. A user can query metadata for a single denomination using the `--denom` flag or all denominations without it.

```sh
simd query bank denom-metadata [flags]
```

Example:

```sh
simd query bank denom-metadata --denom stake
```

Example Output:

```yml
metadata:
  base: stake
  denom_units:
  - aliases:
    - STAKE
    denom: stake
  description: native staking token of simulation app
  display: stake
  name: SimApp Token
  symbol: STK
```

#### total

The `total` command allows users to query the total supply of coins. A user can query the total supply for a single coin using the `--denom` flag or all coins without it.

```sh
simd query bank total [flags]
```

Example:

```sh
simd query bank total --denom stake
```

Example Output:

```yml
amount: "10000000000"
denom: stake
```

### Transactions

The `tx` commands allow users to interact with the `bank` module.

```sh
simd tx bank --help
```

#### send

The `send` command allows users to send funds from one account to another.

```sh
simd tx bank send [from_key_or_address] [to_address] [amount] [flags]
```

Example:

```sh
simd tx bank send cosmos1.. cosmos1.. 100stake
```
