Connect to PrimeTriad

Permissionless Hybrid PPS+ Stratum for Fractal Bitcoin. No account — username is your FB address. Use this page for miner setup, difficulty floors, NiceHash, and MiningRigRentals.

Stratum endpoints

Two regions, three difficulty ports. Pick a host for latency, then a port by miner size — ports are not failover.

Region Host Use for
Global pool.primetriad.com Default endpoint
Europe eu.pool.primetriad.com Lower latency for EU miners
Port Global URL Europe URL Use for
3335 stratum+tcp://pool.primetriad.com:3335 stratum+tcp://eu.pool.primetriad.com:3335 Low difficulty — Bitaxe / small rigs
3334 stratum+tcp://pool.primetriad.com:3334 stratum+tcp://eu.pool.primetriad.com:3334 Default — most miners
3336 stratum+tcp://pool.primetriad.com:3336 stratum+tcp://eu.pool.primetriad.com:3336 High difficulty — large ASICs / farms

Username

YOUR_FB_ADDRESS or YOUR_FB_ADDRESS.worker

Payouts go to the address part. Worker suffix is optional stats label.

Password

x for automatic vardiff (recommended)

Or d=<n> to set a per-worker difficulty floor.

Rewards

Hybrid PPS+ · 1.5% fee · 5 FB finder bonus

On-chain FB payouts after maturity. No Lightning.

Difficulty profiles

Prefer the matching stratum port first. Password d=<n> can still raise a per-worker floor on any port if shares are too chatty.

Hardware Port Password Guidance
Bitaxe / sub-TH 3335 x Low-diff entry; let vardiff settle
Home / mid-size ASIC 3334 x or d=64+ Default profile for most gear
Multi-TH farm 3336 x or d=2048+ High start reduces share flood
NiceHash / rentals 3334 or 3336 See marketplace sections Meet marketplace minimum difficulty rules

NiceHash (buy hashrate → PrimeTriad)

NiceHash does not “list” pools like an app store. Buyers create a SHA256 order and point it at any Stratum that passes the NiceHash Pool Verifier.

Order recipe

  • Algorithm: SHA256ASICBOOST (or SHA256 if required by your UI)
  • Pool hostname: pool.primetriad.com (or eu.pool.primetriad.com for EU latency)
  • Port: 3334 (default) or 3336 for larger orders
  • Username: your Fractal Bitcoin address (optionally .nh)
  • Password: x (or raise with d= if Verifier demands a higher floor)

Verifier checklist

  • Pool difficulty must be ≥ 8 for SHA256ASICBOOST — PrimeTriad meets this.
  • Extranonce2 size ≥ 4 (ckpool default).
  • Run the official Pool Verifier before spending large orders.
  • Hybrid PPS+ credits follow accepted shares — size orders with treasury/buffer health in mind.

MiningRigRentals & hashpower marketplaces

Create a Favorite Pool (or equivalent) on the rental platform, then point rented SHA256 gear at PrimeTriad.

Field Value
Name PrimeTriad FB
Type / algo SHA256
Host pool.primetriad.com or eu.pool.primetriad.com (EU)
Port 3334 (or 3335 / 3336 by size)
Username YOUR_FB_ADDRESS.mrr
Password x

Compatible in principle with MiningRigRentals, Braiins Pool Manager custom pools, and similar tools that speak standard Stratum V1. Always confirm accepted shares on pool.primetriad.com after a test rental.

Troubleshooting

Authorized but 0 shares

Wait for vardiff to settle (up to a few minutes). Bitaxe: prefer password x. Confirm stratum host/port exactly.

High reject rate

Clock sync, stale work after network lag, or difficulty too low/high for the rig. Raise floor with d= on chatty farms.

Wrong difficulty port

Bitaxe struggling? Use :3335. Big ASICs flooding shares? Move to :3336. Same username/password on every port.
