Running devnet


During this tutorials you will need an Echo node and Echo wallet.

Getting started

Running private network is as simple as

./echo_node --devnet --start-echorand --rpc-endpoint

This will create data directory at ~/.echo.devnet with config.ini in it. This file contains various settings and account's private keys that are used during consensus.

Using Echo wallet

To start Echo wallet you need to know node address and port, its chain id and run command:

./echo_wallet \
-s ws:// \
--chain-id e5da051fd6fe4859f9b9cd100fac9ade49be619b9830db53d117b14a48b3931b

If remote node has different chain id then you will get a error with remote chain id which you can copy-paste into your command.

Remote server gave us an unexpected chain_id

Next step is to set password in your wallet with set_password command:

new >>> set_password
Input private data: sw0rdf1sh

Now every time you will open this wallet (with wallet.json file) you will need to unlock it to make any operations with your accounts.

locked >>> unlock
Input private data: sw0rdf1sh

Now you can import account keys.

Working with keys

You can get private keys of devnet accounts in your config.ini. Here listed accounts from init0 to init8 and nathan which is the only account with init balance in default devnet genesis.

Using these private keys you can import accounts into your wallet and do any paid operations.

To import key into wallet you need to run import_key <account> <private key> command:

unlocked >>> import_key nathan
Input private data: 5JjHQ1GqTbqVZLdTB3QRqcUWA6LezqA65iPJbq5craE6MRc4u9K

Note that private key is a private data and entered in the next line after import_key nathan.

If account has initial balances defined in genesis, then you can import them with import_balance command:

unlocked >>> import_balance nathan true
Input private data: [5JjHQ1GqTbqVZLdTB3QRqcUWA6LezqA65iPJbq5craE6MRc4u9K]
