Setup & Configuration

Install Docker

Install Docker Engine from official site

Create a mnemonic you will use only for

Download Sentinel CLI from here

Right click on the download file and make it executable

Open a terminal and type:

./sentinelcli keys add --home "${HOME}/.sentinelcli" --keyring-backend test keyname

Take note of mnemonic and operator address (also make sure to add funds into it)

Clone and configure Restake

Clone the repository and copy the sample .env file ready for your mnemonic

git clone

Go into Restake directory

cd restake

Create your .env file from the sample .env.sample

cp .env.sample .env

Open .env file and add your mnemonic:

MNEMONIC=my hot wallet seed words here that has minimal funds

Open the Dockerfile and if the node version is not the last, update it manually (I put 20 instead 18)

sudo nano Dockerfile

Pre-build your Docker containers with the following commands:

docker compose run --rm app npm install
docker compose build --no-cache

Go into src directory

cd src/

Create your .networks.local.json file from the sample .networks.local.json.sample

cp networks.local.json.sample networks.local.json

Replace the file with this code block and, on restUrl field, select your desired one from here and click on REST tab:

"sentinel": {
"prettyName": "Sentinel 881",
"restUrl": [
"autostake": {
"correctSlip44": false

For restUrl field check this link

Running the script

Run this command adding as last word sentinel which is the network we are going to enable

sudo docker compose run --rm app npm run autostake sentinel

You should see something like that:

> restake@0.1.0 autostake
> node scripts/autostake.mjs sentinel

[09:30:20.268] Loaded Sentinel 881
[09:30:20.458] Bot address is sent1eyhgvkqu48luluafpfn4myg5jr04g6zje9zkkf
[09:30:20.459] Not an operator
[09:30:20.460] Autostake finished

The message "Not an Operator" is fine as we have to submit our operator to Chain Registry

Setting up a timer to run the script on a schedule

You should setup your script to run at the same time each day. We will use the methos based on systemd-timer which allows to run a one-off service with specified rules. This method is arguably preferable to crontab, which we will not cover.

Create a systemd unit file

The unit file describes the application to run. We define a dependency with the timer with the Wants statement. Create the restake.service file

sudo nano /etc/systemd/system/restake.service

Add the following code block


Description=restake service with docker compose

ExecStart=/usr/bin/docker compose run --rm app npm run autostake sentinel


Create a systemd timer file

The timer file defines the rules for running the restake service every hour. All rules are described in the systemd documentation.

Create the restake.timer file

sudo nano /etc/systemd/system/restake.timer

Add the following code block


Description=Restake bot timer

OnCalendar=*-*-* *:00:00


Enable and start the 2 created services

sudo systemctl enable restake.service
sudo systemctl enable restake.timer
sudo systemctl start restake.timer

Check the restake.timer status

With systemctl

sudo systemctl status restake.timer

Or with journalctl in real time:

sudo journalctl -u restake.service -f

You should see something like that:

● restake.timer - Restake bot timer
Loaded: loaded (/etc/systemd/system/restake.timer; enabled; vendor preset: enabled)
Active: active (waiting) since Thu 2023-07-13 12:24:40 UTC; 4min 19s ago
Trigger: Thu 2023-07-13 13:00:00 UTC; 30min left
Triggers: ● restake.service

Jul 13 12:24:40 trinity-management systemd[1]: Started Restake bot timer.

Check the restake.service status

sudo systemctl status restake.service

You should see something like that:

● restake.service - restake service with docker compose
Loaded: loaded (/etc/systemd/system/restake.service; enabled; vendor preset: enabled)
Active: inactive (dead)
TriggeredBy: ● restake.timer

Now you are ready to submit your operator to
