Bridge Server for relaying WalletConnect connections.

This is a fork from WalletConnect version.

I have added support for deploying to AWS elastic beanstalk instead of running within docker. one still need to have a running redis server but that is simple to setup(either get it from AWS or spin up another EC2 instance, and I have changed the EB script to include one)

The main purpose of this fork is really about having an easy to scale out setup using AWS elastic beanstalk(with/without ELB) for production usage. Docker is good but scaling that out would be too complicated(Kubernetes).

Concerning AWS elastic beanstalk, I just port from a python template I work on at here. read more about it there

Local dev work is using local self signed certificates within the docker environment.

Your Walletconnect enabled app needs to be on the same local network.

make dev # ports 80, 443, 5001, 6379 will be exposed locally

Dependencies:

• git
• docker
• make

You will need to have docker swarm enabled:

docker swarm init
# If you get the following error: `could not chose an IP address to advertise...`. You can do the following:
docker swarm init --advertise-addr `curl -s ipecho.net/plain`

Run the following command and fill in the prompts:

git clone https://github.com/WalletConnect/node-walletconnect-bridge
cd node-walletconnect-bridge
make deploy
Bridge URL domain: <your bridge domain>
Email for SSL certificate (default [email protected]):

If you want a grafana dashboard you can use the following commands:

git clone https://github.com/WalletConnect/node-walletconnect-bridge
cd node-walletconnect-bridge
make deploy-monitoring
Bridge URL domain: <your bridge domain>
Email for SSL certificate (default [email protected]):

For this to work you must point grafana.<bridge domain> to the same ip as <bridge domain>.

The config step of the Makefile will ask you whether you are using cloudflare as a DNS proxy for your bridge domain. If you answer yes then the certbot will need a Cloudflare API token that can be obtained from: https://dash.cloudflare.com/profile/api-tokens. The type of token you need is a Edit zone DNS with access to the bridge domain.

The API token will be safeguarded with a docker secret.

This will upgrade your current bridge with minimal downtime.

⚠️ ATTENTION: This will run git fetch && git merge origin/master in your repo ⚠️

make upgrade

This stack deploys 3 containers one of redis, nginx and node.js. You can follow the logs of the nginx container by running the following command:

docker service logs --raw -f walletconnect_nginx
