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, MiningRigRentals, and compounding Hybrid PPS+ into Index Mining.

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.

Compound mining into Index Mining

Official Binding starts at 1 FB. Compound only works after you Bind PrimeIndexer and link Hybrid PPS+ payouts to that stake address. Binding alone still pays your mining address.

1. Mine Hybrid PPS+

Ports 3334–3336. Username is the FB address you will stake with. Password x.

2. Bind PrimeIndexer

Open My Staking, connect UniSat, stake at least 1 FB to PrimeIndexer (1818297:10).

3. Confirm Binding

Wait for the Binding to confirm. If the dashboard still says no Binding, refresh after a few blocks.

4. Link payouts

On the pool dashboard, look up your miner, connect UniSat, select the Binding, and turn on Pay PPS to stake address.

Use the same FB address for Stratum, UniSat, Binding, and the compound toggle. Finder 5 FB still pays the mining address. Merged mining on 3340–3342 does not compound. Step-by-step on the landing page: primetriad.com/#compound.

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=65536+ 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.

Docs: NiceHash supported pools

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.
