Tools to join the axelar network
This tutorial will take 30-60 minutes of dev time and 2-4 hours of waiting for blockchain sync.
Axelar Network is a work in progress. At no point in time should you transfer any real assets using Axelar. Only use testnet tokens that you're not afraid to lose. Axelar is not responsible for any assets lost, frozen, or unrecoverable in any state or condition. If you find a problem, please submit an issue to this repository following the template.
- Mac OS or Ubuntu (tested on 18.04)
- Docker (https://docs.docker.com/engine/install/)
- Axelar faucet: http://faucet.testnet.axelar.network/
- Latest docker images:
Axelar node runs in two containers (one with the core consensus engine and another with threshold crypto process). You can stop/remove all your containers using:
docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)
Clone the repository to use the script and configs:
git clone https://github.com/axelarnetwork/axelarate-community.git
cd axelarate-community
Run the script join/joinTestnet.sh.
Usage: joinTestnet.sh [flags]
Mandatory flags:
--axelar-core Version of axelar-core docker image to run (Format: vX.Y.Z)
--tofnd Version of tofnd docker image to run (Format: vX.Y.Z)
Optional flags:
-r, --root Local directory to store testnet data in (IMPORTANT: this directory is removed and recreated if --reset-chain is set)
--reset-chain Delete local data to do a clean connect to the testnet
See https://hub.docker.com/repository/docker/axelarnet/axelar-core and https://hub.docker.com/repository/docker/axelarnet/tofnd for the latest available versions of the docker images.
Once you join, at the terminal you should see blocks produced:
2:00PM DBG indexed block txs height=2803 module=txindex num_txs=0

By default, logs output to stdout and stderr. You could redirect logs to a file for debugging and error reporting:
join/joinTestnet.sh --axelar-core CORE_VERSION --tofnd TOFND_VERSION &>> testnet.log
On a new terminal window, you could monitor the log file in real time:
tail -f testnet.log
If you find the log containing too much noise and hard to find useful information, you can filter it as following
docker logs -f axelar-core 2>&1 | grep -e threshold -e num_txs -e proxies
Axelar signs meta transactions for Ethereum, meaning that any Ethereum account can send transaction executing commands so long as the commands are signed by Axelar's key. In the exercises, all of the Ethereum-related transactions are sent from address 0xE3deF8C6b7E357bf38eC701Ce631f78F2532987A on Ropsten testnet.

On a new terminal window, enter Axelar node:
docker exec -it axelar-core sh -
By default, the node has an account named validator. Find its address:
axelarcli keys show validator -a -
Go to axelar faucet and get some coins on your validator's address (Your node is not yet a validator for the purpose of this ceremony; it's just the name of the account). http://faucet.testnet.axelar.network/
-
Check that you received the funds
axelarcli q bank balances {validator_addr}
