Paymail Server
This server runs a basic implementation of a Paymail standard service with cut down capabilities specifically built to integrate with a Direct Payments wallet. The main purpose is to allow incoming funds from existing paymail services.
Bitcoin wallets such as Handcash & MoneyButton implement a server to server paymail capability with brfcids 2a40af698840 and 5f1323cddf31 which are a step away from standard bitcoin address use, towards proper SPV. This server will act as a bridge between the old and new, by translating between that legacy protocol and the full SPV direct payment protocol.
Configuring Paymail
The server has a series of environment variables that allow you to configure the behaviours and integrations of the server.
Server
| Key | Description | Default |
|---|---|---|
| DOMAIN_TLD | Domain name and top level domain on which this paymail service runs | carefulbear.com |
| SERVER_PORT | Port which this server should use | :8446 |
| SERVER_HOST | Host name under which this server is found | paymail |
| PAYD_HOST | Host for the wallet we are connecting to | payd |
| PAYD_PORT | Port the PayD wallet is listening on | :8443 |
DNS Records
In order to work with existing infrastructure, an SRV record is required pointing your desired domain at the domain you're running this server from.
# SRV Record
_bsvalias._tcp.yourdomain.com. 3600 10 10 443 where-ever-you-are-running-this-code.com.
# sometimes registrars will make you separate out these values, if so they are as follows:
service: bsvalias
protocol: tcp
TTL: 3600
Priority: 10
Weight: 10
Host: where-ever-you-are-running-this-code.com.
Needless to say the where-ever-you-are-running-this-code.com. must point to your host IP via an A record. If the domain is different then DNSSEC is required. Read more about the Paymail Standard for details.
Working with Paymail Server
There are a set of makefile commands listed under the Makefile which give some useful shortcuts when working with the repo.
Some of the more common commands are listed below:
make pre-commit - ensures dependencies are up to date and runs linter and unit tests.
make build-image - builds a local docker image, useful when testing paymail-server in docker.
make run-compose - runs Paymail Server in compose, a reference PayD wallet will be added to compose soon NOTE the above command will need ran first.
