Use CLI Wallet

In order to use the CLI Wallet, you must have an Echo full node running with an RPC port exposed. If you don't have a full node running yet, follow the installation tutorial.

To run a full node that we can connect to, we need to open the RPC interface, this can be done by:

./echo_node --rpc-endpoint= --testnet

This will open port 6312.

CLI Wallet

The CLI wallet is used to interact with the Echo blockchain and use to generate signatures.

Running the CLI Wallet

All it takes for the CLI wallet to run is a trusted API server to connect to the blockchain. Businesses and individuals run these public API servers.

./echo_wallet -s wss://

In this example, we use the public Echo node API and connect via a secured websocket connection. But you can also use your local node IP and PORT like this:

./echo_wallet -s ws://

If you get an {"remote_chain_id":"$$REMOTE_CHAIN_ID$$","chain_id":"$$CHAIN_ID$$"} error, when the wallet starts, it'd mean that the genesis.json file was changed. It can only happen on testnet or devnet networks.

You can fix it by adding add an argument --chain-id=$$REMOTE_CHAIN_ID$$, where $$REMOTE_CHAIN_ID$$ is a chain ID that reported in the remote_chain_id message.

This will open the CLI wallet and will ask you to provide a passphrase for your local wallet.

Once a new wallet has been created (default wallet file is wallet.json), it will prompt with:

Please use the set_password method to initialize a new wallet before continuing
new >>>

A new wallet needs to be initialized before its first use, by setting a password using the set_password command:

IMPORTANT: Private data, such as a passphrase or private keys, aren't stored by the wallet.

new >>> set_password
Input private data:
locked >>>

Now the wallet can be unlocked by providing the passphrase:

locked >>> unlock
Input private data:
unlocked >>>

Once the wallet has been unlocked, you can import an existing account. If you do not have an account yet, follow the account creation and key importing tutorial.

If you do not import an account, the wallet.json file will not be created and you will have to set_password again next time you open the wallet.

You can get a detailed list of all commands by calling the help command.

By pressing TAB you can get a list of autocomplete commands or complete current if there are no alternatives.

Many calls have an obligatory broadcast-flag as the last argument. If this flag is false, the wallet will create and sign but not broadcast the transaction. This can be very useful for a cold storage setup or to verify transactions.

Opening an RPC Port

The CLI wallet can open an RPC port, so that in be accessed by applications or scripts. This can be done via either:

  • websocket RPC via the -r parameter.

  • HTTP RPC via the -H parameter.

./echo_wallet -s ws:// -H -r
