Dogecoin & Litecoin Merge Mining in 2026: Double Your Scrypt Rewards

Scrypt mining has a feature that most miners underutilise: the ability to earn two cryptocurrency block rewards simultaneously with a single piece of hardware. Dogecoin and Litecoin both use Scrypt proof of work, and both support merged mining (formally called Auxiliary Proof of Work, or AuxPoW) — meaning a pool can submit valid proof-of-work solutions to both networks at once. If you're running a Scrypt ASIC in 2026 and not merge mining, you're leaving money on the table.

What Is Merge Mining (AuxPoW)?

Merged mining allows a miner to simultaneously mine two or more cryptocurrencies that share the same proof-of-work algorithm, without any additional computational work. The mining pool embeds a reference to the auxiliary blockchain (Dogecoin) inside the coinbase transaction of the primary blockchain (Litecoin). When a valid hash is found, it satisfies both networks' difficulty requirements simultaneously.

Dogecoin adopted AuxPoW in September 2014 at block 371,337 — a deliberate decision by the Dogecoin Foundation to align mining incentives with Litecoin's larger hashrate base and improve network security. The protocol change required a hard fork and full miner agreement. Since then, the vast majority of Dogecoin's hashrate has come from miners also mining Litecoin.

How It Works in Practice

You don't need to configure anything special on your ASIC. The merge mining happens at the pool level:

1. Point your Scrypt ASIC to a pool that supports LTC/DOGE merged mining (ViaBTC, F2Pool, Antpool, Poolin).
2. The pool constructs block templates that embed Dogecoin auxiliary data inside the Litecoin coinbase.
3. When your miner finds a valid hash, the pool broadcasts the solution to both the Litecoin and Dogecoin networks.
4. Your earnings arrive as separate payouts in both LTC and DOGE — typically into separate wallet addresses you configure on the pool.

The computational overhead of merge mining is negligible — less than 0.1% additional CPU load on the pool's block construction server, which has no measurable effect on your ASIC's performance or power consumption.

2026 Hardware: Best Scrypt ASICs for DOGE + LTC Mining

Modern Scrypt ASICs are substantially more efficient than previous generations. Top hardware in 2026:

• Antminer L9 (Bitmain) — 16 GH/s at 3,260W (~204 J/GH). The top-of-range Scrypt machine; highest absolute hashrate available in a single unit. Ideal for industrial-scale operations.
• Antminer L7 (Bitmain) — 9.5 GH/s at 3,425W (~361 J/GH). Widely deployed; good secondary-market availability as L9 units ship. Strong pool support and stable firmware.
• Goldshell LT6 — 1.625 GH/s at 1,900W (~1,169 J/GH). Lower efficiency than the L-series, but a lower entry price makes it accessible for smaller operations.
• Antminer L9 Hydro — 16+ GH/s with liquid cooling for data centres that can support immersion or hydro infrastructure.

Profitability: DOGE + LTC Combined

Merge mining's economic value is additive. If your L7 generates $X/day from Litecoin mining alone, merge mining adds DOGE earnings on top — the additional revenue is essentially free, costing only the pool's LTC/DOGE fee spread (typically 1–2%).

At June 2026 prices and difficulty levels:

• Dogecoin trades around $0.12–$0.16 with a network hashrate of approximately 900 TH/s
• Litecoin trades around $65–$80 with approximately 1,200 TH/s of Scrypt hashrate
• Combined revenue from an Antminer L7 at $0.06/kWh electricity: approximately $8–$14/day depending on exact prices (DOGE contributes roughly 35–45% of the total)

Choosing a Merge Mining Pool

Pool selection matters for merge miners. Key criteria:

• ViaBTC — Large pool with explicit LTC + DOGE merge mining, PPS+ payout, ~2% fee. Reliable uptime and detailed earnings dashboard. Good first choice.
• F2Pool — One of the largest pools globally; supports merge mining with 2.5% fee on DOGE earnings. Established track record and multi-coin payout options.
• Antpool — Bitmain's own pool; natural choice if you run Antminer hardware. Supports merge mining with 0% fee on some earning modes (FPPS on LTC; DOGE merged automatically).
• Poolin — Supports merge mining with competitive fees; strong presence in Asia-Pacific markets.
• Litecoinpool.org — Litecoin-native pool with PPS scheme; DOGE merge mining included at no extra fee. Smaller pool means higher payout variance.

Avoid pools below 50 TH/s of Scrypt hashrate — small pool size means infrequent block finds and high payout variance that makes it difficult to project earnings over weekly cycles.

Wallet Setup for Dual Payouts

You'll need separate wallets for LTC and DOGE. Both currencies are supported by:

• Ledger hardware wallets (LTC and DOGE both natively supported)
• Trezor (LTC and DOGE supported on Model T and newer)
• Exodus and Atomic Wallet — software options for smaller balances
• Exchange wallets (Binance, Coinbase, Kraken) — convenient but not recommended for long-term storage

Configure separate withdrawal addresses for LTC and DOGE in your pool dashboard. Most pools default to paying both at a minimum threshold — set your thresholds based on current transaction fees (DOGE fees are typically fractions of a cent; LTC fees are minimal at <$0.01).

Tax and Accounting Considerations

Merged mining creates two separate taxable events per mining session in most jurisdictions — one for LTC earned, one for DOGE earned — each valued at the market price at the time of receipt. Ensure your mining accounting software (CoinTracking, Koinly, etc.) correctly imports both streams from your pool's CSV export.

Key Takeaways

• Merged mining (AuxPoW) lets Scrypt ASICs earn DOGE and LTC simultaneously with zero additional hardware cost.
• Point your miner to ViaBTC, Antpool, F2Pool, or Poolin — all support LTC/DOGE merge mining natively.
• DOGE contributes roughly 35–45% of total Scrypt mining revenue at June 2026 price levels.
• The best hardware in 2026 is the Antminer L9 (16 GH/s) or L7 (9.5 GH/s) for large operations; Goldshell LT6 for smaller setups.
• Set up separate LTC and DOGE withdrawal addresses in your pool dashboard to receive both payouts automatically.
