A project by the HOPR Association
HOPR is a privacy-preserving messaging protocol which enables the creation of a secure communication network via relay nodes powered by economic incentives using digital tokens.
A good place to start is the Getting Started guide on YouTube which walks through the following instructions using GitPod.
The following instructions show how the latest community release may be installed. The instructions should be adapted if you want to use the latest development release or any other older release.
Using the hoprd npm package:
mkdir MY_NEW_HOPR_TEST_FOLDER
cd MY_NEW_HOPR_TEST_FOLDER
npm install @hoprnet/hoprd@1.73
All our docker images can be found in our Google Cloud Container Registry.
Each image is prefixed with gcr.io/hoprassociation/$PROJECT:$RELEASE.
The latest tag represents the master branch, while the latest-constantine tag
represents the most recent release/* branch.
You can pull the Docker image like so:
docker pull gcr.io/hoprassociation/hoprd:latest-constantine
For ease of use you can set up a shell alias to run the latest release as a docker container:
alias hoprd='docker run --pull always -ti -v ${HOPRD_DATA_DIR:-$HOME/.hoprd-db}:/app/db -p 9091:9091 -p 3000:3000 -p 3001:3001 gcr.io/hoprassociation/hoprd:latest-constantine'
IMPORTANT: Using the above command will map the database folder used by hoprd to a local folder called .hoprd-db in your home directory. You can customize the location of that folder further by executing the following command:
HOPRD_DATA_DIR=${HOME}/.hoprd-better-db-folder eval hoprd
Also all ports are mapped to your local host, assuming you stick to the default port numbers.
NOTE: This setup should only be used for development or if you know what you
are doing and don't neetd further supported. Otherwise you should use the npm
or docker setup.
You will need to clone the hoprnet repo first:
git clone https://github.com/hoprnet/hoprnet
If you have direnv set up properly your nix-shell will be
configured automatically upon entering the hoprnet directory and enabling it
via direnv allow. Otherwise you must enter the nix-shell manually:
nix develop
Now you may follow the instructions in Develop.
The hoprd provides various command-line switches to configure its behaviour. For reference these are documented here as well:

As you might have noticed running the node without any command-line argument might not work depending on the installation method used. Here are examples to run a node with some safe configurations set.
The following command assumes you've setup a local installation like described in Install via NPM.
cd MY_NEW_HOPR_TEST_FOLDER
DEBUG=hopr* npx hoprd --admin --init --announce --identity .hopr-identity --password switzerland --forwardLogs --apiToken <MY_TOKEN>
Here is a short break-down of each argument.
hoprd
--admin # enable the node's admin UI, available at localhost:3000
--init # initialize the database and identity if not present
--announce # announce the node to other nodes in the network and act as relay if publicly reachable
--identity .hopr-identity # store your node identity information in your test folder
--password switzerland # set the encryption password for your identity
--forwardLogs # enable the node's log forwarding to the ceramic network
--apiToken <MY_TOKEN> # specify password for accessing admin panel and REST API (REQUIRED)
The following command assumes you've setup an alias like described in Install via Docker.
hoprd --identity /app/db/.hopr-identity --password switzerland --init --announce --host "0.0.0.0:9091" --admin --adminHost 0.0.0.0 --forwardLogs --apiToken <MY_TOKEN> --environment jungfrau
Here is a short break-down of each argument.
hoprd
--identity /app/db/.hopr-identity # store your node identity information in the persisted database folder
--password switzerland # set the encryption password for your identity
--init # initialize the database and identity if not present
--announce # announce the node to other nodes in the network and act as relay if publicly reachable
--host "0.0.0.0:9091" # set IP and port of the P2P API to the container's external IP so it can be reached on your host
--admin # enable the node's admin UI
--adminHost 0.0.0.0 # set IP of the Rest API to the container's external IP so it can be reached on your host
--forwardLogs # enable the node's log forwarding to the ceramic network
--apiToken <MY_TOKEN> # specify password for accessing admin panel and REST API(REQUIRED)
--environment jungfrau # an environment is defined as a chain plus a number of deployed smart contract addresses to use on that chain
# each release has a default environment id set, but the user can override this value
# nodes from different environments are **not able** to communicate
At the moment we DO NOT HAVE backward compatibility between releases. We attempt to provide instructions on how to migrate your tokens between releases.
MANUAL.info and take note of the network name..hopr-identity and .db folders.HOPRd instance using latest release, this will create new .hopr-identity and .db folders, observe the account address.HOPRd instance if HOPRd operates on the same network as last release, you can compare the two networks using info.yarn # Install dependencies and sets up workspces
yarn build # Builds contracts, clients, etc
# starting network
yarn run:network
# running normal node alice (separate terminal)
DEBUG=hopr* yarn run:hoprd:alice
# running normal node bob (separate terminal)
DEBUG=hopr* yarn run:hoprd:bob
# fund all your nodes to get started
yarn run:faucet:all
We use mocha for our tests. You can run our test suite across all packages using the following command:
yarn test
To run tests of a single package (e.g. hoprd) execute:
yarn --cwd packages/hoprd test
To run tests of a single test suite (e.g. Identity) within a package (e.g. hoprd) execute:
For instance, to run only the Identity test suite in hoprd, you need to
run the following:
yarn --cwd packages/hoprd test --grep "Identity"
In a similar fashion, our contracts can be tested in isolation. For now, you need to pass the file to be tested, as hardhat does not support --grep
yarn test:contracts test/HoprChannels.spec.ts
In case a package you need to test is not included in our package.json,
please feel free to update it as needed.
To make sure we add the least amount of untested code to our codebase,
whenever possible all code should come accompanied by a test. To do so,
locate the .spec or equivalent test file for your code. If it does not
exist, create it within the same file your code will live in.
Afterwards, ensure you create a breaking test for your feature. For example, the following commit added a test to a non-existing feature. The immediate commit provided the actual feature for that given test. Repeat this process for all the code you add to our codebase.
(The code was pushed as an example, but ideally, you only push code that has working tests on your machine, as to avoid overusing our CI pipeline with known broken tests.)
We run a fair amount of automation using Github Actions. To ease development of these workflows one can use act to run workflows locally in a Docker environment.
E.g. running the build workflow:
act -j build
For more information please refer to act's documentation.
End-to-end testing is usually performed by the CI, but can also be performed locally by executing:
./scripts/run-integration-tests-source.sh
Read the full help information of the script in case of questions:
./scripts/run-integration-tests-source.sh --help
That command will spawn multiple hoprd nodes locally from the local
source-code and run the tests against this cluster of nodes. The tests can be
found in the files test/*.sh. The script will cleanup all nodes once completed
unless instructed otherwise.
An alternative to using the local source-code is running the tests against a NPM package.
./scripts/run-integration-tests-npm.sh
If no parameter is given the NPM package which correlates to the most recent Git tag will be used, otherwise the first parameter is used as the NPM package version to test.
Read the full help information of the script in case of questions:
./scripts/run-integration-tests-npm.sh --help
In some unique cases, some bugs might not had been picked up by our end-to-end testing and instead only show up when deployed to production. To avoid having to see these only after a time consuming build, a cluster of nodes can be deployed to Google Cloud Platform which is then used to run tests against it.
A requirement for this setup is a working gcloud configuration locally.
The easiest approach would be to authenticate with gcloud auth login.
The cluster creation and tests can be run with:
FUNDING_PRIV_KEY=mysecretaccountprivkey \
./scripts/run-integration-tests-gcloud.sh
The given account private key is used to fund the test nodes to be able to perform throughout the tests. Thus the account must have enough funds available.

./scripts/run-integration-tests-gcloud.sh --help
The deployment nodes and networks is mostly orchestrated through the script
files in scripts/ which are executed by the Github Actions CI workflows.
Therefore, all common and minimal networks do not require manual steps to be
deployed.
However, sometimes it is useful to deploy additional nodes or specific versions
of hoprd. To accomplish that its possible to create a cluster on GCP using the
following scripts:
./scripts/setup-gcloud-cluster.sh my-custom-cluster-without-name
Read the full help information of the script in case of questions:
./scripts/setup-gcloud-cluster.sh --help
The script requires a few environment variables to be set, but will inform the
user if one is missing. It will create a cluster of 6 nodes. By default these
nodes will use the latest Docker image of hoprd and run on the Goerli
network. Different versions and different target networks can be configured
through the parameters and environment variables.
To launch nodes using the xDai network one would execute (with the
placeholders replaced accordingly):
HOPRD_PROVIDER="<URL_TO_AN_XDAI_ENDPOINT>" \
HOPRD_TOKEN_CONTRACT="<ADDRESS_OF_TOKEN_CONTRACT_ON_XDAI>" \
./scripts/setup-gcloud-cluster.sh my-custom-cluster-without-name
A previously started cluster can be destroyed, which includes all running nodes, by using the same script but setting the cleanup switch:
HOPRD_PERFORM_CLEANUP=true \
./scripts/setup-gcloud-cluster.sh my-custom-cluster-without-name
The creation of a hoprd cluster on GCP can be enhanced by providing a topology
script to the creation script:
./scripts/setup-gcloud-cluster.sh \
my-custom-cluster-without-name \
gcr.io/hoprassociation/hoprd:latest \
`pwd`/scripts/topologies/full_interconnected_cluster.sh
After the normal cluster creation the topology script will then open channels between all nodes so they are fully interconnected. Custom topology scripts can be easily added and used in the same manner. Refer to the referenced scripts as a guideline on how to get started.
