# module\_bank

#### `bank` module

#### Introduction

The `bank` module maintains the state of two primary objects:

* Account balances by address;
* Total supply of tokens on the chain

`bank` module tracks and provides query support for the total supply of all assets used in the application. It also supports token transfer functionalities. Specifically, the total supply is updated whenever a token is:

* **Minted**, e.g. Token created by the [mint](/cronos-pos-chain-protocol/module_overview/module_inflation-including-mint.md#mint-module) module; or
* **Burned**, e.g. Token distorted by the [slashing](https://github.com/crypto-org-chain/chain-docs/blob/Gitbook/docs/chain-details/module_slashing/README.md) module.

#### Transactions and Queries

#### Transactions

**`tx bank send [from_key_or_address] [to_address] [amount] [network_id]` - Send Funds**

You can transfer tokens to a designated address by the `tx bank send` command. For example, we can send 10 CRO from `address_a` to `address_b` by

```bash
$ chain-maind tx bank send <address_a> <address_b> 10cro --chain-id <chain-id>

## Transaction payload##
{"body":{"messages":[{"@type":"/cosmos.bank.v1beta1.MsgSend","from_address"....}
confirm transaction before signing and broadcasting [y/N]: y
```

#### Queries

**`query bank balances [address]` - Check the balance of a specified account**

One can check the current balance of a specified account by:

```json
$ chain-maind query bank balances <address> --output json | jq
    {
    "balances": [
        {
        "denom": "basecro",
        "amount": "[token_balance]"
        }
    ],
    "pagination": {
        "next_key": null,
        "total": "0"
    }
    }
```

**`query bank total` - Check the total supply of the token**

You can also check the current total supply of the token by:

```json
$ chain-maind query bank total --output json | jq
    {
    "supply": [
        {
        "denom": "basecro",
        "amount": "[total_supply_amount]"
        }
    ]
    }
```

#### Appendix

| Key                  | Type           | Example                               |
| -------------------- | -------------- | ------------------------------------- |
| `SendEnabled`        | \[]SendEnabled | \[{denom: "basecro", enabled: true }] |
| `DefaultSendEnabled` | bool           | true                                  |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cronos-pos.org/cronos-pos-chain-protocol/module_overview/module_bank.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
