Overview

The Polygon gateway acts as a bridge between your Polygon node and the Marlin relay network, enabling them to understand and talk to each other. In addition, it handles most of the Marlin related interactions for you like optimizing peer sets, attesting messages, generating tickets, etc.

For validators

Step 1: Contact us to set up a fully managed dedicated gateway for you.

Step 2: Add the gateway as a persistent peer to your polygon node by adding it in the TrustedNodes array.

# Use the identity obtained above
[Node.P2P]
TrustedNodes = ["enode://<identity>@ip:port"]

That's it!

Manual setup

This section assumes that marlinctl is installed already. See here if you have not installed it.

Step 1: Generate a client identity for the gateway by running the below command and entering a passphrase when prompted

sudo marlinctl gateway polygon keystore create

Step 2: Create the gateway (currently using staking data from kovan)

sudo marlinctl gateway polygon create --bootstrap-addr "54.193.224.20:8002"

Step 3: Retrieve the polygon identity of the gateway by checking the logs

sudo marlinctl gateway polygon logs

Step 4: Add the gateway as a persistent peer to your polygon node by adding it in the TrustedNodes array.

# Use the identity obtained above
[Node.P2P]
TrustedNodes = ["enode://<identity>@<ip>:<port>"]

That's it!
