Share Link Parameters

Mole supports an extended set of parameters for each protocol. Below are the technical details for correctly forming links.

VLESS

The recommended protocol for bypassing blocks using Reality and Vision.

Example: vless://uuid@host:port?security=reality&sni=google.com&fp=chrome&pbk=publicKey&sid=shortId&flow=xtls-rprx-vision&type=tcp#ServerName

Parameter	Description
security	reality or tls
sni	Domain to imitate
fp	Browser fingerprint (chrome, firefox, safari, edge)
pbk	Public Key for Reality
flow	xtls-rprx-vision (recommended for TCP+Reality)
type	Transport: tcp, ws, grpc or xhttp
alpn	ALPN list, e.g. h3 for HTTP/3. Implies TLS
mode	XHTTP mode: auto (default), stream-one, stream-up, packet-up

Transports that no longer exist

Xray-core removed both the HTTP/2 (type=h2) and the standalone QUIC (type=quic) transports, so links using them cannot connect on any client built on a current core — Mole rejects them with an explanatory message rather than failing silently. QUIC's replacement is XHTTP over HTTP/3: type=xhttp with mode=stream-one and alpn=h3. For a QUIC-based protocol, use Hysteria2.

Hysteria2

A QUIC-based protocol, optimized for unstable networks.

Example: hysteria2://password@host:port?sni=example.com&obfs=salamander&obfs-password=pass&up=100&down=200#ServerName

Parameter	Description
sni	Domain presented in the TLS handshake
obfs	salamander — the only obfuscation Hysteria2 defines. Needs obfs-password to take effect
obfs-password	Obfuscation password
up / down	Bandwidth in Mbps. Also accepted as upmbps / downmbps, and with a unit suffix (up=100mbps). Declaring both switches on the "brutal" congestion controller; omit them to stay on BBR
insecure	1 or true disables certificate verification
alpn	ALPN to pin. Left to the core's default (h3) when absent
fp	Browser fingerprint

Shadowsocks (SS)

Support for AEAD ciphers and SIP002.

Example: ss://base64(cipher:password)@host:port#ServerName
