vltrig

A fork of XMRig miner tailored for HashVault mining pools.

Anti-censorship first. Helping miners bypass network restrictions and DNS blocking that prevent access to mining pools. Mining should be accessible to everyone, everywhere.

Focus Areas

• Anti-censorship features (DoH, secure DNS resolution)
• UI/UX improvements
• HashVault pool optimizations
• Tracking upstream XMRig for updates and security fixes

Not Changing

• Hashing algorithms
• Mining performance
• Donation mechanics (original XMRig donation is preserved)

Prebuilt binaries are available on the Releases page.

Platform	Architecture	Notes
Linux	x64	Static binary (musl libc)
Windows	x64	MinGW build
macOS	x64	Intel Macs
macOS	ARM64	Apple Silicon

Note: Prebuilt binaries are CPU-only. For GPU mining, build from source with -DWITH_OPENCL=ON and/or -DWITH_CUDA=ON.

Features

DNS-over-HTTPS (DoH)

Secure DNS resolution via DNS-over-HTTPS using HTTP/2. When enabled (default), the miner queries the pool's authoritative nameservers directly via DoH, bypassing potentially censored or compromised local DNS resolvers.

How it works

1. Queries a public DoH server for the pool's NS records
2. Resolves NS hostnames via the same DoH server
3. Queries the authoritative NS directly via DoH for pool IP addresses

Command line options

Option	Description
--dns-pool-ns	Enable authoritative NS resolution (default: enabled)
--no-dns-pool-ns	Disable, use system DNS
--dns-doh-primary=HOST	Primary DoH server (default: dns.google)
--dns-doh-fallback=HOST	Fallback DoH server (default: dns.nextdns.io)

Config file

{
  "dns": {
    "pool-ns": true,
    "doh-primary": "dns.google",
    "doh-fallback": "dns.nextdns.io"
  }
}

RandomX Only

Optimized for Monero mining. Only RandomX (rx/0) algorithm is advertised to pools.

Disabled algorithms

Algorithm	Status
CryptoNight (cn/0, cn/1, cn/2, cn/r, etc.)	Filtered out
CryptoNight-Lite, Heavy, Pico, Femto	Disabled
Argon2	Disabled
KawPow	Disabled
GhostRider	Disabled

Default Pool

HashVault pool is preconfigured as default with TLS and certificate pinning.

Setting	Value
URL	pool.hashvault.pro:443
TLS	Enabled
Fingerprint	420c7850e09b7c0bdcf748a7da9eb3647daf8515718f36d9ccfdd6b9ff834b14
