# XSN Block Explorer - Server
## Run
1. We need the xsn rpc server running, download the latest one from [xsn releases ](https://github.com/X9Developers/XSN/releases ), then, start the rpc server with: `bin/xsnd -txindex -addressindex -spentindex -rpcport=51473 -rpcuser=dummy -rpcpassword=replaceme`
2. Edit the [application.conf ](server/conf/application.conf ).
* In case you modified the parameters to start the xsn rpc server, update the credentials.
* Set the credentials to access a postgres database.
* Replace `play.modules.enabled += "com.xsn.explorer.modules.SeederModule"` with `play.modules.enabled += "com.xsn.explorer.modules.PollingSeederModule"` .
3. Run the application with: `sbt run`
## Test
Run the `sbt test` command to execute the tests.
