Injective Chain Documentation Overview `injectived`Using `injectived`

# Using `injectived`

The following information explains the functions you can use from injectived , the command-line interface that connects to Injective and enables you to interact with the Injective blockchain. Every active validator and full node runs injectived and communicates with their node via injectived . In this relationship, injectived operates as both the client and the server. You can use injectived to interact with the Injective blockchain by uploading contracts, querying data, managing staking activities, working with governance proposals, and more. For more general information at the command line, run injectived --help. For more information about a specific injectived command, append the -h or --help flag after the command, such as injectived query --help.

# Accessing a Node

To query the state and send transactions, you must connect to a node, which is the access point to the entire network of peer connections. You can either run your own full node or connect to someone else’s. See Networks.

# Configuring `injectived`

injectived enables you to interact with the node that runs on the Injective network, whether you run it yourself or not. To configure injectived, edit the the config.toml file in the ~/.injective/config/ directory.

# Example 1: Querying Blockchain State

For testing purpose, we assume you are connected to a node in your local private network.

Now that your very own Injective node is running, it is time to try sending tokens from the first account you created to a second account. In a new terminal window, start by running the following query command:

injectived query bank balances $MY_VALIDATOR_ADDRESS --chain-id=injective-1

You should see the current balance of the account you created, equal to the original balance of inj you granted it minus the amount you delegated via the gentx. Now, create a second account:

injectived keys add recipient --keyring-backend=file # Put the generated address in a variable for later use. RECIPIENT=$(injectived keys show recipient -a --keyring-backend=file)

The command above creates a local key-pair that is not yet registered on the chain. An account is created the first time it receives tokens from another account. Now, run the following command to send tokens to the recipient account:

injectived tx bank send $MY_VALIDATOR_ADDRESS $RECIPIENT 1000000inj --chain-id=injective-1 --keyring-backend=file # Check that the recipient account did receive the tokens. injectived query bank balances $RECIPIENT --chain-id=injective-1

Finally, delegate some of the stake tokens sent to the recipient account to the validator:

injectived tx staking delegate $(injectived keys show my_validator --bech val -a --keyring-backend=file) 500inj --from=recipient --chain-id=injective-1 --keyring-backend=file # Query the total delegations to `validator`. injectived query staking delegations-to $(injectived keys show my_validator --bech val -a --keyring-backend=file) --chain-id=injective-1

You should see two delegations, the first one made from the gentx, and the second one you just performed from the recipient account.

# Example 2: Generate, Sign and Broadcast a Transaction

Running the following command

injectived tx bank send $MY_VALIDATOR_ADDRESS $RECIPIENT 1000inj --chain-id=injective-1 --keyring-backend=file

will run the following steps:

generate a transaction with one Msg (x/bank's MsgSend), and print the generated transaction to the console.
ask the user for confirmation to send the transaction from the $MY_VALIDATOR_ADDRESS account.
fetch $MY_VALIDATOR_ADDRESS from the keyring. This is possible because we have set up the CLI's keyring in a previous step.
sign the generated transaction with the keyring's account.
broadcast the signed transaction to the network. This is possible because the CLI connects to the node's Tendermint RPC endpoint.

The CLI bundles all the necessary steps into a simple-to-use user experience. However, it's possible to run all the steps individually too.

# Generating a Transaction

Generating a transaction can simply be done by appending the --generate-only flag on any tx command, e.g.:

injectived tx bank send $MY_VALIDATOR_ADDRESS $RECIPIENT 1000inj --chain-id=injective-1 --generate-only

This will output the unsigned transaction as JSON in the console. We can also save the unsigned transaction to a file (to be passed around between signers more easily) by appending > unsigned_tx.json to the above command.

# Signing a Transaction

Signing a transaction using the CLI requires the unsigned transaction to be saved in a file. Let's assume the unsigned transaction is in a file called unsigned_tx.json in the current directory (see previous paragraph on how to do that). Then, simply run the following command:

injectived tx sign unsigned_tx.json --chain-id=injective-1 --keyring-backend=file --from=$MY_VALIDATOR_ADDRESS

This command will decode the unsigned transaction and sign it with SIGN_MODE_DIRECT with $MY_VALIDATOR_ADDRESS's key, which we already set up in the keyring. The signed transaction will be output as JSON to the console, and, as above, we can save it to a file by appending > signed_tx.json.

Some useful flags to consider in the tx sign command:

--sign-mode: you may use amino-json to sign the transaction using SIGN_MODE_LEGACY_AMINO_JSON,
--offline: sign in offline mode. This means that the tx sign command doesn't connect to the node to retrieve the signer's account number and sequence, both needed for signing. In this case, you must manually supply the --account-number and --sequence flags. This is useful for offline signing, i.e. signing in a secure environment which doesn't have access to the internet.

# Signing with Multiple Signers

Please note that signing a transaction with multiple signers or with a multisig account, where at least one signer uses SIGN_MODE_DIRECT, is not yet possible. You may follow this Github issue (opens new window) for more info.

Signing with multiple signers is done with the tx multisign command. This command assumes that all signers use SIGN_MODE_LEGACY_AMINO_JSON. The flow is similar to the tx sign command flow, but instead of signing an unsigned transaction file, each signer signs the file signed by previous signer(s). The tx multisign command will append signatures to the existing transactions. It is important that signers sign the transaction in the same order as given by the transaction, which is retrievable using the GetSigners() method.

For example, starting with the unsigned_tx.json, and assuming the transaction has 4 signers, we would run:

# Let signer1 sign the unsigned tx. injectived tx multisignsign unsigned_tx.json signer_key_1 --chain-id=injective-1 --keyring-backend=file > partial_tx_1.json # Now signer1 will send the partial_tx_1.json to the signer2. # Signer2 appends their signature: injectived tx multisignsign partial_tx_1.json signer_key_2 --chain-id=injective-1 --keyring-backend=file > partial_tx_2.json # Signer2 sends the partial_tx_2.json file to signer3, and signer3 can append his signature: injectived tx multisignsign partial_tx_2.json signer_key_3 --chain-id=injective-1 --keyring-backend=file > partial_tx_3.json
