To set up LTC/DOGE merged mining on ViaBTC, connect a compatible Scrypt ASIC to the LTC Stratum endpoint, enter your worker name, and select PPS+ or PPLNS as your LTC payment method. ViaBTC automatically handles DOGE merged mining, so you do not need a separate DOGE pool connection. This guide covers the ASIC settings, checks after connecting, and DOGE withdrawal setup.

What Is LTC/DOGE Merged Mining?

Litecoin and Dogecoin both use the Scrypt proof-of-work algorithm. Dogecoin has supported Auxiliary Proof of Work (AuxPoW) since 2014, a protocol mechanism that allows valid Scrypt mining work produced for one chain to also be submitted as a block candidate on a compatible auxiliary chain. This is the technical basis for LTC/DOGE merged mining: a miner does not run two separate mining jobs, and a Scrypt ASIC does not need to split its hashrate between two networks.

In practice, a miner configures the ASIC to connect to a Litecoin mining pool. Where that pool supports LTC/DOGE merged mining, it independently constructs and submits the corresponding Dogecoin block data through AuxPoW and credits eligible DOGE rewards under its own published rules. ViaBTC's LTC pool documentation describes this arrangement: the miner points to the LTC Stratum endpoint only, and the pool handles the Dogecoin submission process on the back end (ViaBTC LTC mining setup guide).

This distinction matters for setup expectations. There is no DOGE pool URL to enter, no second miner instance to run, and no hashrate to divide. The ASIC's configuration is identical to standard LTC pool mining; the merged-mining behavior is a pool-side function, not an ASIC firmware feature.

What You Need Before Connecting a Scrypt ASIC

Before configuring the miner, confirm the following:

• A Scrypt ASIC compatible with LTC mining (for example, the Bitmain Antminer L9 series).
• A wired Ethernet connection to the ASIC's management interface, since most Scrypt ASICs, including the L9, use an RJ45 10/100M connection rather than Wi-Fi.
• A ViaBTC account with an active LTC pool worker configuration.
• Adequate electrical capacity and cooling for the unit's rated power draw.

As a manufacturer-sourced hardware example, Bitmain specifies the 16 GH/s Antminer L9 at a typical wall power of 3,360 W at 25°C, a power efficiency of 210 J/GH, and an input voltage range of 220–277 V single-phase. Bitmain notes that actual hashrate can vary by roughly ±3% and wall power by roughly ±5% from these typical figures (BITMAIN L9 specifications). Using the specified wall-power figure, continuous 24-hour operation corresponds to an estimated 80.64 kWh per day (3.36 kW × 24 hours), a calculation that reflects miner electricity use only and excludes cooling, ventilation, or other site loads. This example is included to illustrate the electrical planning involved before deployment, not as a hashrate or revenue recommendation.

Configuring the ASIC for a Litecoin Mining Pool

The following sequence applies to ViaBTC's current LTC pool configuration. Because pool settings can change, verify the exact values in ViaBTC's official documentation before entering them.

1. Sign in to a ViaBTC account and select the LTC pool.
2. Choose PPS+ or PPLNS as the LTC payment method (see the following section for the distinction).
3. Connect the Scrypt ASIC to Ethernet and locate its local IP address, typically through a network scanning tool or the router's connected-device list.
4. Log in to the ASIC's browser-based management interface using the device's default or configured credentials.
5. Open the page labeled Miner Configuration, Pools, or an equivalent section, depending on the firmware.
6. Enter the primary Stratum URL: stratum+tcp://ltc.viabtc.io:3333.
7. Enter the worker name in the format userID.workerID, using your actual ViaBTC account identifier for userID. The workerID after the dot must contain only lowercase letters and numbers and be no more than 64 characters long. For example, the full worker name could be viabtc.001. A worker password is optional; any value satisfies the ASIC's field requirement, and it is not an account security credential.
8. If the ASIC firmware supports multiple pool entries, add stratum+tcp://ltc.viabtc.io:443 as a backup pool for connection continuity. This entry does not add hashrate or create a second concurrent mining job; it only allows the miner to reconnect if the primary endpoint becomes unreachable.
9. Save and apply the configuration.

According to ViaBTC's documentation, after the miner has operated continuously for approximately 10–15 minutes, worker status, pool-estimated hashrate, and rejected-share data should become visible in the account dashboard (ViaBTC LTC mining setup guide).

Choosing a Payment Method: PPS+ vs. PPLNS

ViaBTC allows LTC merged-mining participants to select either PPS+ or PPLNS as their LTC payment method. Under PPS+, miners are compensated for valid shares submitted, while transaction fees are distributed separately under PPLNS logic; this shifts more block-discovery and orphan-risk variance onto the pool. Under PPLNS, distributions depend on blocks the pool actually finds and the miner's submitted shares within the applicable PPLNS window, so short-term results can vary with pool luck (PPS+ and PPLNS payment methods).

For LTC/DOGE merged mining specifically, ViaBTC's current rule is that DOGE rewards are distributed under PPLNS regardless of which payment method is selected for LTC. Selecting PPS+ for LTC reduces exposure to Litecoin block-discovery variance for that component, but it does not make DOGE merged-mining rewards fixed, guaranteed, or predictable on a per-settlement basis (ViaBTC's LTC merged-mining rules). Earnings under either method continue to depend on network difficulty, pool fees, uptime, and the share of accepted work over time.

How DOGE Merged-Mining Rewards Are Credited

ViaBTC's current merged-mining documentation lists several Scrypt auxiliary coins eligible alongside LTC, with DOGE settlement occurring approximately every two hours. This two-hour figure refers to internal reward settlement and account crediting, not an on-chain withdrawal schedule. A credited DOGE balance reflects accounting on the pool's platform; it does not mean the coins have been sent to an external wallet (ViaBTC's LTC merged-mining rules).

It is also useful to separate the measurements involved at each stage of this process:

• ASIC-reported hashrate: the device-side hashrate shown on the miner's own interface. Depending on the device, firmware, and selected field, this may be a real-time estimate or an average over a stated period.
• Pool-estimated hashrate: calculated by ViaBTC from submitted shares over a rolling period, and not expected to match the device reading exactly at any given moment.
• Accepted and rejected shares: shares are validated individually; rejected shares are the broader category, with stale or invalid shares as specific subtypes.
• Credited rewards: LTC and DOGE amounts recorded to the account under the applicable payment method.
• Withdrawals: a separate step that moves credited balances to an external address.

Verifying That the Miner Is Working

After applying the configuration, allow the miner to run for a period before reviewing results, since pool-estimated hashrate is calculated from accumulated shares rather than an instantaneous value. Confirm that the worker shows as active in the dashboard, that accepted shares are increasing, and that the rejected-share rate remains low relative to accepted shares. If the worker never appears as active, first check the Stratum URL, worker-name format, network connection, and whether the miner is running locally. If the worker is submitting shares but the rejection rate remains high, check network latency and stability, miner temperature, and firmware (ViaBTC rejection-rate troubleshooting).

Setting Up DOGE Withdrawals

DOGE rewards credited through merged mining can be withdrawn according to ViaBTC's account withdrawal settings, which are separate from the two-hour settlement schedule described above. To set up automatic withdrawals to an external wallet:

1. Sign in to ViaBTC and go to Assets → My Assets.
2. Select DOGE from the coin selector and open its automatic withdrawal settings.
3. Choose Withdraw to Address, enter the correct DOGE withdrawal address, and complete the required security authentication.
4. Check that automatic withdrawal is enabled, then review the configured minimum payout amount and payout mode on the Auto-Withdrawal Setting page.

ViaBTC supports two payout modes: Payout by Account Balance and Payout by Daily Earnings. The daily-earnings mode retains earnings settled on the payout day and pays out eligible earnings accumulated from previous complete natural days. The selected mode must meet the applicable payout conditions; if revenue sharing is enabled, its amount is deducted first.

As of September 28, 2026, ViaBTC's documentation lists a minimum automatic withdrawal threshold of 20 DOGE for external addresses, with withdrawals processed once daily between 10:00 and 18:00 GMT+8, subject to the configured threshold and payout conditions (set up automatic DOGE withdrawals). This processing window describes when ViaBTC initiates the withdrawal, not a guarantee of when funds arrive at the destination wallet, since on-chain confirmation times depend on the Dogecoin network. Thresholds, schedules, and eligibility rules for auto-withdrawal are product settings that may change, so it is advisable to check the current configuration in the account dashboard before relying on a specific figure.

Common Setup Mistakes

Several errors commonly affect new LTC/DOGE merged-mining setups:

• Entering a separate DOGE Stratum URL or attempting to run a second mining instance, which is unnecessary since the pool manages DOGE submission from the LTC work stream.
• Using uppercase letters or unsupported characters in the workerID after the dot, or entering an incorrect userID, which can prevent the worker from registering correctly.
• Assuming a credited DOGE balance has already been withdrawn, rather than recognizing settlement and withdrawal as distinct steps.
• Selecting PPS+ under the assumption that it makes DOGE rewards fixed, when DOGE distribution follows PPLNS regardless of the LTC payment method chosen.
• Comparing the ASIC-reported hashrate directly against the pool's estimated hashrate without checking the calculation methods and reporting periods of the selected fields.

FAQ

Do I need separate hardware for LTC and DOGE?

No. A single compatible Scrypt ASIC connects to the LTC pool, and the pool manages DOGE merged mining on its own infrastructure.

Do I enter a DOGE pool URL into the ASIC?

No. For ViaBTC's LTC/DOGE arrangement, only the LTC Stratum endpoint is configured on the ASIC.

Does selecting PPS+ make DOGE earnings fixed?

No. ViaBTC's documentation states that DOGE merged-mining rewards are distributed under PPLNS even when LTC is set to PPS+.

Why does the ASIC's displayed hashrate differ from the pool's figure?

The ASIC reports device-side hashrate, which may be a real-time estimate or an average depending on the selected field and firmware. The pool estimates hashrate from submitted shares over a reporting period. Check the period associated with each field before comparing the figures; short-term differences do not necessarily indicate a problem (ViaBTC hashrate explanation).

When does credited DOGE arrive in an external wallet?

Reward settlement, account crediting, and withdrawal are separate steps. ViaBTC currently settles merged-mining rewards approximately every two hours, while automatic withdrawals to an external address are processed once daily within a stated window, subject to the account's configured threshold and selected payout mode.
