Initialize submodules, install dependencies, compile the Smart Contracts:
If there is no need to build docker images for the TokenBridge components (oracle, monitor, UI), initialize submodules, install dependencies, compile the Smart Contracts:
```
yarn initialize
```
Then refer to the corresponding README files to get information about particular TokenBridge component.

## Overview
Please refer to the [POA TokenBridge](../README.md) overview first of all.
- Deployed version: https://bridge-monitoring.poa.net/
- Deployed version serves several monitor configurations:
* https://bridge-monitoring.poa.net/poa
* https://bridge-monitoring.poa.net/xdai
* https://bridge-monitoring.poa.net/wetc
* https://bridge-monitoring.poa.net/amb-dai
* https://bridge-monitoring.poa.net/amb-poa

As soon as the process finishes, use the URL described above to get the statistic.
### Cron
You can create cron job to run workers (see `crontab.example` for reference):
## Ad-hoc monitoring
There is a possibility to get bridge statistics without running the web interface use the commands provided above. In this case the results will be located in the `responses` directory.
## Build the image without running the monitor
To build the image change the directory:
```
cd monitor
```
And run the docker composer:
```
docker-compose -f docker-compose-build.yml build

## Rollback the Last Processed Block in Redis
If the bridge does not handle an event properly (i.e. a transaction stalls due to a low gas price), the Redis DB can be rolled back. You must identify which watcher needs to re-run. For example, if the validator signatures were collected but the transaction with signatures was not sent to the Foreign network, the `collected-signatures` watcher must look at the block where the corresponding `CollectedSignatures` event was raised.
