Do I need my exact ASIC model listed to join a pool?

Usually no. Most modern ASICs speak standard Stratum for their algorithm (SHA-256 for Bitcoin). If your miner can enter a Stratum URL (host:port), a username/wallet, and a worker name, it can typically connect. Exact SKUs mainly affect tuning (difficulty targets, expected hashrate, and cooling limits).

What does a pool need to support for Antminer/WhatsMiner/Avalon devices?

Stable SHA-256 Stratum behavior: correct job delivery, clean difficulty updates (vardiff), reliable session handling, and clear documentation for ports and worker formatting. For larger farms, multi-region gateways and DDoS resilience matter more than anything.

What is the fastest way to test if my ASIC is configured correctly?

Point a single device at one Stratum endpoint, wait 10–20 minutes, and verify accepted shares (not just reported hashrate). If rejects are high, double-check algorithm/port, worker format, DNS, and that the pool is reachable on that port.

Can you help me build a pool that attracts ASIC owners?

Yes. We build and harden SHA-256 pools (BTC/BCH/BSV/XEC and other SHA-256 chains) with clear onboarding docs, tuned Stratum endpoints, monitoring, and secure payout operations—so ASIC owners can connect quickly and stay connected.

ASIC miner supported brands & models (SHA‑256): from early Antminers to the newest WhatsMiner & Avalon generations

This page is built for ASIC owners who want a clear answer to two questions: “Will my miner connect to a SHA‑256 pool?” and “What should a pool provide so miners stay online?” We cover the major SHA‑256 ASIC brands and their model families from older generations to newer releases, then translate that into practical pool onboarding steps (URLs, ports, worker formats, failover, and troubleshooting). When you’re building or setting up a SHA256 pool, we help you configure miners (Antminer/WhatsMiner/Avalon), firmware settings, and the right pool URLs/ports for stable hashrate.

Quick reality check: Bitcoin mining uses SHA‑256. If your ASIC is Scrypt (Litecoin/DOGE), X11 (Dash), Kadena, Kaspa, etc., it won’t connect to SHA‑256 endpoints. The good news: if your hardware is SHA‑256 and supports Stratum, it will typically connect to a standard pool.

How compatibility works (Stratum + algorithm)

Most ASIC web dashboards ask for three things: a pool URL (Stratum host:port), a username or wallet, and a worker name. If your device is a SHA‑256 ASIC, it usually speaks Stratum well enough to connect to any standard SHA‑256 pool—regardless of whether it’s an Antminer, WhatsMiner, Avalon, or another brand.

Algorithm first: SHA‑256 hardware connects to SHA‑256 ports only.
Ports matter: pools often offer multiple ports for different difficulty targets and TLS/SSL.
“Model” mostly affects tuning: higher-hashrate units benefit from better vardiff ranges and multi-region routing.

Onboarding checklist for ASIC owners

Confirm you’re on SHA‑256: Bitcoin (BTC) and many related chains use SHA‑256.
Use one endpoint first: configure a single Stratum URL and verify accepted shares.
Set a meaningful worker name: e.g., farm1-rack2-s21-07.
Add failover pools: only after your primary is stable (and confirm DNS + ports are reachable).
Watch rejects/stales: high rejects often mean wrong port/algorithm, unstable network, or overly aggressive tuning.

If you run a pool: what ASIC owners expect (and what we build)

ASIC owners don’t want “mystery config.” They want clear onboarding that works across Antminer, WhatsMiner, and Avalon dashboards: ports, worker format, backup URLs, and proof the pool stays online during stress. That’s why production pools lean on multi-region gateways, monitored node layers, and tight payout controls.

Multi-region Stratum gateways: reduce stales and keep farms connected during peering hiccups.
Vardiff tuned per class of miner: small/home miners and big farms can coexist without rejected share spikes.
DDoS survivability + runbooks: a pool can’t “grow” if it collapses during the first attack.
Secure ops: hardened wallets, payout guardrails, backups, and tested restores.

If you’re planning a pool build (BTC/BCH and other SHA‑256 chains), see: multi‑region Stratum architecture, security hardening, and managed ops & monitoring.

FAQ & common search queries

Is my Antminer / WhatsMiner / Avalon compatible with any Bitcoin pool?

For SHA‑256 pools, compatibility is mostly about Stratum behavior and the correct port. If your miner can enter a Stratum URL, credentials, and a worker name, it can typically connect. Pools that publish clear onboarding docs dramatically reduce rejects and support tickets.

Why do I see hashrate but no accepted shares?

Hashrate alone can be misleading. Accepted shares confirm the pool is receiving valid work. Check algorithm/port, DNS, firewall rules, and that your worker format matches the pool’s expectation.

Do I need custom firmware to join a pool?

No—stock firmware usually works. Custom firmware can help with tuning and efficiency, but pools should be compatible with standard Stratum clients first. If you do tune, do it gradually and monitor rejects and temperature margins.

Can you build a pool that markets to ASIC owners?

Yes. Beyond the backend, we help you publish onboarding pages that cover the brands and model families miners actually own, with simple steps, ports, and troubleshooting—so the page converts search traffic into connected hashrate.
