What is this?

A web-based toolkit for interacting with the Avalanche network. Explore C-Chain data, verify contracts, check validator status, manage wallets, inspect L1s — all through direct JSON-RPC calls to your node. No middlemen, no external APIs.

~/security0x02

0x02

Privacy & Security

Runs entirely on your local machine. No data is ever sent to external servers. All RPC calls go directly from your browser to the configured node endpoint. No backend. No telemetry. No tracking. Your keys and addresses never leave your machine.

✓ Zero outbound connections

✓ No cookies, no analytics

✓ Static build — runs offline after load

✓ Keys never leave the browser

Getting Started

Clone, install, run. Three commands and you're in.

$ git clone https://github.com/arminreiter/avaxtoolkit.git# clone the repo

$ cd avaxtoolkit

$ pnpm install# install deps

$ pnpm dev# start dev server

Open http://localhost:3000 and configure your RPC endpoint in Settings.

~/tunnel0x04

0x04

Connecting to a Remote Validator

Validator on a remote server? Use an SSH tunnel to forward the RPC port locally. No need to expose port 9650 to the internet.

$ ssh -N -L 9650:localhost:9650 user@your-validator-ip# forward port 9650

-N — no remote shell, tunnel only

-L 9650:localhost:9650 — bind local:remote

Set your endpoint to http://localhost:9650 in Settings. All traffic flows through the encrypted SSH tunnel directly to your validator.

[browser] ──── localhost:9650 ──── ssh tunnel ──── [validator node]

How It Works

Makes JSON-RPC calls directly from the browser to Avalanche node APIs — Platform (P-Chain), Contract (C-Chain), and AVM (X-Chain). No intermediary server, no proxy.

Built as a static Next.js application. Once built, serve it from any static file server or run locally with pnpm dev.

▸ next.js · static export · no server runtime

▸ ethers.js · direct RPC calls

▸ tailwind · shadcn/ui · radix primitives
