In order to run a full node that we can connect to, we need to open the RPC interface, this can be done by:
This will open port
8090 and make it available over the internet (unless you run behind a router/firewall).
If you want it to be open for your machine only, replace
Note, that the full node needs to synchronize the blockchain with the network first, which may take a few minutes.
To start participating in consensus you should add option
--account-info=[account_id, EDDSA_private_key]. Where
account_id is ID of your account and
EDDSA_private_key is ed215519 key that you registered with.
./bin/echo_node --rpc-endpoint="0.0.0.0:8090" --account-info=["1.6.2", "DET67rm27uYRVMQdN88EkpHE6LVVgivM8d8AmbkpauBFDuy"]

The Cli-Wallet is used to interact with the blockchain. Everything that adds new data to the blockchain requires a signature from a private key. These signed transactions can be produced by the cli-wallet.
All it takes for the cli-wallet to run is a trusted API server to interface with the blockchain. These public API servers are run by businesses and individuals. In this example, we use the public API node of Echo and connect via secured websocket connection but you can to change the url to your private node:
Url which we will use in example:
./bin/echo_wallet -s wss://echo-dev.io/ws
This will open the cli-wallet and unless you already have a local wallet, will ask you to provide a passphrase for your local wallet.
Once a new wallet has been created (default wallet file is
it will prompt with
Please use the set_password method to initialize a new wallet before continuing new >>>
As said, a new wallet needs to be initialized before use. Password is set with
Private data, such as passphrase or private key, is not echoed by the wallet
new >>> set_password Input private data: supersecretpassphrase locked >>>
Now the wallet can be
unlocked by providing the passphrase:
locked >>> unlock Input private data: supersecretpassphrase unlocked >>>
You can get a detailed list of all commands by calling
TAB you can get a list of autocomplete commands or complete current if there is no alternatives.
Many calls have a obligatory
broadcast-flag as last argument. If this flag is
false, the wallet will construct and sign, but not broadcast the transaction. This can be very useful for a cold storage setup or to verify transactions.
The cli-wallet can open a RPC port so that you can interface your application with it. You have the choices of
./bin/echo_wallet -s wss://echo-dev.io/ws -H 127.0.0.1:8092 -r 127.0.0.1:8093
