Brief summary

Agoric was founded in 2018 with the ambition to enable developers to rapidly deploy dapps and DeFi markets on-chain using familiar JavaScript components.

Today, we’re incredibly proud to announce that we were fortunate enough to be invited to take part in the Agoric Incentivized Testent which is limited to 150 seats. Below we’ll document how we set up our validator node and how we found the experience.

Setting up the validator

As noted above, we decided to use Contabo VPS to host our validator node as we felt that they were very cost effective and were able to meet all the requirements to host an Agoric testnet validator. Contabo is the cheapest VPS around, our setup costs only €8.99 per month which is far cheaper than its competitors.

Setting up the validator couldn’t have been easier. The documentation provided by the Agoric team was meticulous and easy to follow, even Linux beginners wouldn’t have had too much trouble setting up their nodes. Any issues that other testnet participants faced were quickly assisted and resolved by friendly support staff in the Agoric Discord channel.

Setting up telemetry

One of the testnet tasks was to connect our validator to Prometheus analytics as well as Cosmos metrics. For this step you are expected to have a little knowledge on basic Linux administration as you have to allow specific ports past your firewall to allow Prometheus to poll your validator and to get analytics streamed.

As we were running a Ubuntu machine, we simply enabled the ports like so:

sudo ufw allow 26660
sudo ufw allow 9464
sudo ufw allow 1317

There was also another step not fully documented which was to export the following environmental variable


To tie this environmental variable to the ag-chain-cosmos service, we had to simply stick it into the service file stored in /etc/systemd/system/ag-chain-cosmos.service shown below and then restart the service.

Description=Agoric Cosmos daemon

ExecStart=/home/gunnertwin/go/bin/ag-chain-cosmos start --log_level=warn


Closing thoughts

Overall we were very happy with this onboarding stage and are extremely excited to work on upcoming stages of this incentivized testnet to assist Agoric realize their huge but realistic ambitions.

We would like to take this opportunity once again to thank Agoric for the opportunity to participate in this Incentivized testnet and hope this is the start of a long fruitful collaboration.
