Yingyan Accelerator fully implements the WireGuard protocol, which consists of only 4000 lines of code—1/100th the size of IPsec—yet offers 3-5 times faster transmission speeds. Its streamlined code means a smaller attack surface and enhanced security, allowing you to enjoy extreme speeds without worrying about privacy breaches.
Yingyan Accelerator enforces the industry's strictest zero-logs policy, which means we do not record your connection time, websites visited, IP address, or any browsing data. This policy has been independently audited by the renowned security firm Cure53, with a full report published to verify our commitments.
Yingyan Accelerator's smart routing engine monitors global node latency and load in real-time, automatically connecting you to the best route. One-click connectivity results in latencies as low as 15ms, providing a smooth experience for video conferences, online gaming, or 4K streaming.
Yingyan Accelerator has deployed over 3000 high-speed servers across more than 80 countries and regions, including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server operates in RAM-only mode, erasing all data upon reboot, effectively eliminating the possibility of data retention at the hardware level.
With a single Yingyan Accelerator account, you can protect your smartphone, computer, tablet, smart TV, and router simultaneously—up to 6 devices connected at once, allowing your entire family to share a secure network without extra fees. After configuring your router, even IoT devices that don’t support accelerator can be protected.
Yingyan Accelerator has a bilingual customer service team proficient in both English and Chinese, offering 24/7 assistance. Whether it's installation, connectivity issues, or account management, you can receive immediate, professional help via online chat or email, with an average response time of under 2 minutes.
Learn how the cutting-edge routing protocol used by Yingyan Accelerator delivers unparalleled speed and security
Yingyan Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard implements full accelerator functionality with only about 4000 lines of code, whereas traditional IPsec requires over 600,000 lines. This streamlined code not only means a smaller attack surface but also lower latency and higher throughput. In our internal tests, WireGuard's handshake speed was found to be three times faster than IKEv2 and eight times faster than IPsec.
Yingyan Accelerator's implementation of WireGuard uses the Noise protocol framework for key exchange, employing Curve25519 for ECDH key negotiation, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been widely validated in both academia and industry, providing a forward-thinking security guarantee against quantum computing attacks.
In certain network environments, WireGuard's UDP traffic may face restrictions. Yingyan Accelerator includes smart protocol switching capabilities that automatically detect network conditions and seamlessly switch between WireGuard, IKEv2, and our proprietary obfuscation protocol to ensure stable connections in any environment. The entire switching process is completed within 500 milliseconds, making it nearly unnoticeable to users.
Multi-layer encryption technology and a strict privacy policy comprehensively protect your digital life
Yingyan Accelerator employs AES-256-GCM encryption mode to secure all transmitted data. AES-256 is the encryption standard approved by the NSA for protecting 'top secret' information, requiring billions of years to crack even with the most powerful supercomputers available today. Each connection generates a unique session key, ensuring forward secrecy.
Yingyan Accelerator operates its own private DNS server cluster, ensuring all DNS queries are resolved through the encrypted connection, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection, ensuring that your real IP address remains hidden under all circumstances. You can use the built-in leak testing tool to verify your protection status at any time.
Yingyan Accelerator's network lock feature (Kill Switch) immediately cuts off all internet traffic if the acceleration connection is unexpectedly dropped, preventing any data from leaking in an unencrypted state. This feature supports both system-wide and application-specific modes, allowing all traffic to be protected or only designated applications to have protection, offering maximum flexibility to users.
High-speed connections optimized for streaming and online entertainment, letting you enjoy global content seamlessly
Yingyan Accelerator's high-speed nodes are specifically optimized to reliably support the transmission requirements of 4K Ultra HD (2160p) video streams. Whether it's watching HD movies, live sports events, or music videos, Yingyan Accelerator provides a stable, smooth, and buffer-free viewing experience. With gigabit broadband, connection speeds can consistently exceed 500Mbps.
Yingyan Accelerator has specially optimized for online gaming. Our intelligent routing engine automatically selects the route with the lowest latency to game servers. In our tests, connections to Asia-Pacific game servers achieved latencies as low as 10ms and as low as 60ms for North American servers. Our DDoS protection feature helps you avoid malicious attacks during gaming.
Yingyan Accelerator has enabled P2P optimization features on nodes in over 30 countries worldwide. We do not limit the bandwidth or speed of P2P protocols like BitTorrent, while protecting your download activities from ISP monitoring and throttling through encrypted connections. The port forwarding feature enhances seeding efficiency, allowing faster upload speeds.
