Klaytn RPC endpoint

This is a general guide on deploying an Klaytn RPC endpoint for your Chainlink Node(s).

Official Klaytn Docs are available here

NOTE

This document assumes base operating system is Debian 11

Klaytn RPC Endpoints:

Websocket
- ws://<your_ip_address>:8552
HTTP
- http://<your_ip_address>:8551

Install Dependencies

Before we can get our Ethereum node running, we need to install some necessary software.

we'll install some packages that we'll need or will at least be handy to have.

sudo apt install -y curl wget jq node-ws telnet traceroute npm htop tree

Optional: Download Snapshot

baobab (testnet) snapshots

cypress (mainnet) snapshots

Once downloaded, you will want to uncompress the tarball in the directory you set as your `DATA_DIR` in your `ken-linux-amd64/conf/kend.conf` configuration file.

In this example, it would be /home/<username>/kend/data

Download ken tarball
