+# Blockchain Command-Line Interface
+
+> [!NOTE]
+> Since Greenfield Command Line interface is derived from Cosmos, The majority of the content in this page is copied from the [Cosmos SDK](https://docs.cosmos.network/main/core/cli).
+
+There is no set way to create a CLI, but Greenfield typically use the [Cobra Library](https://github.com/spf13/cobra). 
+Building a CLI with Cobra entails defining commands, arguments, and flags. Commands understand the 
+actions users wish to take, such as `tx` for creating a transaction and `query` for querying the application. 
+Each command can also have nested subcommands, necessary for naming the specific transaction type. 
+Users also supply **Arguments**, such as account numbers to send coins to, and flags to modify various 
+aspects of the commands, such as gas prices or which node to broadcast to.
+
+### Transaction Command
+Here is an example of a command a user might enter to interact with `gnfd` in order to send some tokens:
+
+```bash
+gnfd tx bank send $MY_ADDRESS $RECIPIENT 1000BNB --gas auto
+```
+
+The first four strings specify the command:
+
+* The subcommand `tx`, which contains all commands that let users create transactions.
+* The subcommand `bank` to indicate which module to route the command to `x/bank` module in this case.
+* The type of transaction `send`.
+
+The next two strings are arguments: the `from_address` the user wishes to send from, the `to_address` of the recipient, 
+and the `amount` they want to send. Finally, the last few strings of the command are optional flags to indicate 
+how much the user is willing to pay in fees.
+
+### Transaction Data
+Greenfield utilizes the EIP712 transaction format. To view the transaction data, you can use the `print-eip712-msg-type` flag.
+Below is an example of how to display the transaction data of sending tokens.
+
+```shell
+gnfd tx bank send $MY_ADDRESS $RECIPIENT 1000BNB --print-eip712-msg-type
+```
+
+From the output, we can obtain the following three fields:
+
+1. **EIP712MessageType**: This field represents the EIP712 messages format of the transaction.
+```json
+{
+  "Coin": [
+    {
+      "name": "amount",
+      "type": "uint256"
+    },
+    {
+      "name": "denom",
+      "type": "string"
+    }
+  ],
+  "EIP712Domain": [
+    {
+      "name": "chainId",
+      "type": "uint256"
+    },
+    {
+      "name": "name",
+      "type": "string"
+    },
+    {
+      "name": "salt",
+      "type": "string"
+    },
+    {
+      "name": "verifyingContract",
+      "type": "string"
+    },
+    {
+      "name": "version",
+      "type": "string"
+    }
+  ],
+  "Fee": [
+    {
+      "name": "amount",
+      "type": "Coin[]"
+    },
+    {
+      "name": "gas_limit",
+      "type": "uint256"
+    },
+    {
+      "name": "granter",
+      "type": "string"
+    },
+    {
+      "name": "payer",
+      "type": "string"
+    }
+  ],
+  "Msg1": [
+    {
+      "name": "amount",
+      "type": "TypeMsg1Amount[]"
+    },
+    {
+      "name": "from_address",
+      "type": "string"
+    },
+    {
+      "name": "to_address",
+      "type": "string"
+    },
+    {
+      "name": "type",
+      "type": "string"
+    }
+  ],
+  "Tx": [
+    {
+      "name": "account_number",
+      "type": "uint256"
+    },
+    {
+      "name": "chain_id",
+      "type": "uint256"
+    },
+    {
+      "name": "fee",
+      "type": "Fee"
+    },
+    {
+      "name": "memo",
+      "type": "string"
+    },
+    {
+      "name": "msg1",
+      "type": "Msg1"
+    },
+    {
+      "name": "sequence",
+      "type": "uint256"
+    },
+    {
+      "name": "timeout_height",
+      "type": "uint256"
+    }
+  ],
+  "TypeMsg1Amount": [
+    {
+      "name": "amount",
+      "type": "string"
+    },
+    {
+      "name": "denom",
+      "type": "string"
+    }
+  ]
+}
+```
+
+2. **MessageData**: This field represents the messages data of the transaction, displayed in a readable format.
+```json
+{
+  "msg1": {
+    "amount": [
+      {
+        "amount": "1000",
+        "denom": "BNB"
+      }
+    ],
+    "from_address": "0x0aA5170C854AA093e1c32F15285dE4Bf7f6802Ce",
+    "to_address": "0x2123B607e1b9E8Ae65FbE12585C1bE6838Bb32C7",
+    "type": "/cosmos.bank.v1beta1.MsgSend"
+  }
+}
+```
+
+3. **TxRawBytes**: This field represents the encoded byte array of the transaction.
+```json
+0a88010a85010a1c2f636f736d6f732e62616e6b2e763162657461312e4d736753656e6412650a2a307830614135313730433835344141303933653163333246313532383564453442663766363830324365122a3078323132334236303765316239453841653635466245313235383543316245363833384262333243371a0b0a03424e4212043130303012021200
+```
+
+Once you have obtained these three fields of the transaction, you can use `gnfd-tx-sender` to send the transaction
+instead of using a command. Here are the steps:
+
+1. Visit the [gnfd-tx-sender](https://gnfd-tx-sender.nodereal.io/) website.
+2. Connect your wallet and switch to the correct network.
+3. Navigate to the `Custom Tx` page and fill in the aforementioned three fields accordingly.
+4. Click the `Submit` button and sign in the wallet when prompted.
+5. Wait for confirmation.
+
+### Query Commands
+
+Queries are objects that allow users to retrieve information about the application's state. 
+
+This `queryCommand` function adds all the queries available to end-users for the application. This typically includes:
+
+* **QueryTx** and/or other transaction query commands from the `auth` module which allow the user to search for a transaction by inputting its hash, a list of tags, or a block height. These queries allow users to see if transactions have been included in a block.
+* **Account command** from the `auth` module, which displays the state (e.g. account balance) of an account given an address.
+* **Validator command** from the Cosmos SDK rpc client tools, which displays the validator set of a given height.
+* **Block command** from the Cosmos SDK rpc client tools, which displays the block data for a given height.
+* **All module query commands the application is dependent on,
+
+Here is an example of a `queryCommand`:
+
+```shell
+## query the metadata of BNB
+gnfd q bank denom-metadata --node https://greenfield-chain.bnbchain.org:443
+```
+
+## Environment variables
+
+Each flag is bound to its respective named environment variable. Then name of the environment variable consist of two parts 
+- capital case `basename` followed by flag name of the flag. `-` must be substituted with `_`. 
+- For example flag `--home` for application with basename `GNFD` is bound to `GNFD_HOME`. It allows reducing 
+the amount of flags typed for routine operations. For example instead of:
+
+```sh
+gnfd --home=./ --node=<node address> --chain-id="greenfield_1017-1" tx ... --from=<key name>
+```
+
+this will be more convenient:
+
+```sh
+# define env variables in .env, .envrc etc
+GNFD_HOME=<path to home>
+GNFD_NODE=<node address>
+GNFD_CHAIN_ID="greenfield_1017-1"
+GNFD_KEYRING_BACKEND="file"
+
+# and later just use
+gnfd tx ... --from=<key name>
+```

+# Account Balance
+
+## Abstract
+The bank module is responsible for handling BNB transfers between
+accounts and module accounts.
+
+In addition, the bank module tracks and provides query support for the total
+supply of BNB in the application.
+
+## Quick Start
+
+### Query Balances
+
+To query the balances of an account, you can use the following command.
+
+```shell
+gnfd q bank balances ${receiver} --node ${node} 
+```
+
+You can specify any valid address you want to query via ${receiver}.
+
+
+${node} is the rpc address of a Greenfield node.
+
+- Mainnet
+
+    ```js
+    node = "https://greenfield-chain.bnbchain.org:443"
+    ```
+
+- Testnet
+
+    ```js
+    node = "https://gnfd-testnet-fullnode-tendermint-us.bnbchain.org:443"
+    ```
+
+
+### Send
+
+To transfer some coins you can use `send` command.
+```shell
+gnfd tx bank send ${key} ${receiver} ${coins} --home ~/.gnfd --node ${node}  -y
+```
+
+${key} is the name of local key.
+
+${coins} defines the coins you want to transfer, for example, `500000000000000000000BNB`.
+
+### Multi-send
+
+Sometimes, you may want to transfer tokens to multiple people. `multi-send` command can be used for the purpose.
+
+```shell
+gnfd tx bank multi-send ${key} ${receiver1} ${receiver2} ${coins} --home ~/.gnfd --node ${node}  -y
+```
+
+## Detailed 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
+gnfd query bank --help
+```
+
+#### balances
+
+The `balances` command allows users to query account balances by address.
+
+```sh
+gnfd query bank balances [address] [flags]
+```
+
+Example:
+
+```sh
+gnfd query bank balances 0x73a4Cf67b46D7E4efbb95Fc6F59D64129299c2E3
+```
+
+Example Output:
+
+```yml
+balances:
+- amount: "10000000000000000000000"
+  denom: BNB
+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
+gnfd query bank denom-metadata [flags]
+```
+
+Example:
+
+```sh
+gnfd query bank denom-metadata --denom BNB
+```
+
+Example Output:
+
+```yml
+metadata:
+  base: BNB
+  denom_units:
+    - aliases:
+        - wei
+      denom: BNB
+      exponent: 0
+  description: The native staking token of the Greenfield.
+  display: BNB
+  name: ""
+  symbol: ""
+  uri: ""
+  uri_hash: ""
+```
+
+#### 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
+gnfd query bank total [flags]
+```
+
+Example:
+
+```sh
+gnfd query bank total --denom BNB
+```
+
+Example Output:
+
+```yml
+amount: "1000000000000000800000000000"
+denom: BNB
+```
+
+### Transactions
+
+The `tx` commands allow users to interact with the `bank` module.
+
+```sh
+gnfd tx bank --help
+```
+
+#### send
+
+The `send` command allows users to send funds from one account to another.
+
+```sh
+gnfd tx bank send [from_key_or_address] [to_address] [amount] [flags]
+```
+
+Example:
+
+```sh
+gnfd tx bank send addr1.. addr2.. 100000000000000000000BNB
+```
