Hysteria2 is ProofKit's QUIC/UDP transport. Salamander obfuscation XORs the entire QUIC packet, including the handshake that carries the SNI, so there is no clear VPN fingerprint on the wire and traffic looks like generic UDP.
Salamander obfuscation XORs every byte of the QUIC packet, including the QUIC Initial that carries the TLS ClientHello. That means the SNI is not on the wire at all, and a censor's deep packet inspection sees random noise instead of a QUIC long-header or a recognizable VPN handshake. For DPI the SNI value does not even matter, because it is obfuscated.
Hysteria2 rides QUIC over UDP, so it can keep working where TCP-based transports are throttled but UDP still flows. It generally offers higher throughput with slightly higher latency than VLESS Reality. Where UDP or QUIC is throttled instead, ProofKit's TCP transports are the better fit, which is why the marketplace offers all three.
Hysteria2 shares ProofKit's billing and routing with every other transport: pay per measured GB in non-custodial TON escrow, no monthly subscription, and optional 2-hop routing through an entry node that forwards encrypted traffic to the exit. The server uses a self-signed certificate that your client pins by SHA-256 hash.
Hysteria2 needs an Xray-core client such as Happ. Your subscription bundles every transport a route supports, and the client can url-test and auto-select the fastest working one. An advanced Xray JSON profile can add hands-off Reality-to-Hysteria2 failover, while a simple subscription lets the client pick on connect.
Hysteria2 is a QUIC/UDP transport with Salamander obfuscation. VLESS Reality is a TCP transport that camouflages its handshake as ordinary HTTPS. Hysteria2 hides the SNI by obfuscating the whole packet and tends to push more throughput; Reality has the best latency and works anywhere TCP works.
No. Salamander XORs the entire QUIC packet, so the SNI is never visible on the wire. What matters is that UDP/QUIC is not throttled and the server IP is not blocklisted. This is the opposite of plain Reality, where the SNI is the cleartext camouflage and matters a lot.
An Xray-core based client such as Happ. Import your ProofKit subscription and the client can auto-select Hysteria2 when it is the fastest working transport for the route.
No. It uses the same pay-per-GB pricing, the same 2-hop options, and the same non-custodial TON escrow as every other ProofKit transport. You pay only for measured traffic and can withdraw unused balance.
Pick a route by country, price, uptime, and proof status. Pay only for traffic you actually use. Unused TON balance is withdrawable from the escrow, subject to pending charges.
