ℹ️ How Chain Proxy Works

A chain proxy routes your traffic through two proxies in sequence:

You → Config 1 (Worker/CDN) → Config 2 (Chain) → Internet

This fixes your outgoing IP address to the chain proxy's IP, ensuring a consistent IP for all destinations.

Supported Protocols

VLESS — vless://uuid@server:port?params
VMess — vmess://base64-json
Trojan — trojan://password@server:port?params
Shadowsocks — ss://base64(method:pass)@server:port
SOCKS — socks://user:pass@server:port
HTTP — http://user:pass@server:port
SSH — Sing-box only (4-field input: server, port, username, password)

Output Formats

Xray JSON — Use with any Xray-compatible client (v2rayN, v2rayNG, Nekoray, etc.)
Sing-box JSON — Use with sing-box client

Supported Transports

TCP, TCP (http header), WebSocket, gRPC, HTTPUpgrade

Supported TLS

TLS, Reality, None

⚠️ Important Notes

SOCKS & HTTP configs must include username and password.
Xray does not support raw (headerless TCP) configs.
Shadowsocks cannot have any transport (WebSocket, gRPC, etc.) and cannot have TLS.
SSH is only supported by Sing-box — Xray tab is disabled when SSH is used.

Proxy URL Enhancer

Adds cs (cipher suites), fm (fragment mask) and fp to VLESS / Trojan URLs (supports single or multiple URLs)

—

⚙️ Enhancement Options

Server (IP / Domain)

Fingerprint (fp)

Cipher Suites (cs) — empty to skip

Final Mask (fm) — empty to skip

Paste VLESS or Trojan URL(s) above to enable

📋 Enhanced URL(s)

ℹ️ How the Enhancer Works

Paste VLESS or Trojan URL(s) (one per line) and this tool adds:

cs — TLS cipher suite list for the handshake.
fm — final mask / fragment settings (packet fragmentation for TLS handshakes).
fp — TLS fingerprint (default unsafe, overrides the URL's own value).
Server — IP/domain override, auto-filled from the pasted URL; empty to keep the original address.

cs and fm are only added when the config uses tls security. Clear a field to skip that parameter.

⚠️ TLS required: this tool only works with configs that have TLS enabled (security tls or reality). Non-TLS configs are not supported and will not work.

Client Requirements

Windows — use v2rayN version 7.24.7 or higher.
Android — use PattNG or v2rayNG version 2.3.4 or higher.
