Overview

What is an MTProto Proxy?

MTProto is the custom transport protocol Telegram uses to carry messages between the app and its servers. An MTProto proxy is a lightweight relay that forwards that traffic on behalf of the client, letting users connect to Telegram from networks where the service is blocked or heavily filtered. Unlike a traditional SOCKS or HTTP proxy, MTProto proxies only carry Telegram traffic and speak Telegram's own obfuscated wire format, which makes them difficult for censors to fingerprint.

StormyCloud runs a free, public MTProto proxy reachable over both the clearnet and the I2P network. There is no registration, no logging, and no rate limits. The proxy is based on Telegram's official reference implementation, which is open source and available on GitHub.

The same proxy, reachable as a hidden service over the I2P network. Create a standard I2P client tunnel pointing at the destination below and connect Telegram to the local port that tunnel exposes.

Secret Formats

MTProto proxy secrets come in two flavors. Most modern Telegram clients accept either, but the padded form is recommended because it enables random padding on the wire, making the traffic look less distinctive to deep-packet inspection.

With Random Padding (recommended)

Prefixed with dd, this format tells the client to enable random padding on every packet. Hides packet-length patterns and defeats basic traffic fingerprinting.

Plain Secret

The raw 16-byte secret without the dd prefix. Older clients that do not support random padding fall back to this format automatically.

How to Connect

1. One-click (clearnet)

Tap the button below on any device with Telegram installed. Telegram will prompt you to add StormyCloud's proxy with the server, port, and secret already filled in.

Open in Telegram
2. Manual setup

In Telegram, go to Settings → Data and Storage → Proxy Settings → Add Proxy, choose MTProto, and enter the server, port, and secret listed above.

3. Over I2P

In your I2P router console, open I2P Hidden Services Manager → New Client Tunnel and create a Standard tunnel pointing at the destination above. Pick any free local port (for example 127.0.0.1:1080), save, and start the tunnel. Then in Telegram add an MTProto proxy with that local address and port and the secret listed above.
