Batch Interacting with ZKsync via Cloud Phones: A Practical Guide for Zero-Cost Airdrop Arbitrage

In 2024, the Layer 2 ecosystem competition is heating up, and ZKsync, as a benchmark for zk-rollup technology, has already ignited the enthusiasm of countless active users with the anticipated airdrop of its native token. Recalling the frenzy of the Arbitrum airdrop in 2023—where tokens were distributed based on the reward pool per interacting address, with a single address receiving over $100,000 at most—ZKsync’s airdrop model is highly likely to follow the same “interaction weight” logic. This means number of addresses × interaction depth = profit scale. For those seeking side hustles, cross-border e-commerce, social media marketing, or game farming, this is undoubtedly one of the most cost-effective forms of “digital labor” right now.

But the reality is harsh: a single physical phone can run at most 2-3 app clones, and device fingerprints are highly susceptible to overlap; manually performing interactions is time-consuming and labor-intensive, with a maximum of 10-20 addresses per day; more critically, platform risk control will blacklist accounts based on IP, device parameters, and behavioral patterns. How can you operate in batches safely, efficiently, and at low cost? After months of testing, I’ve developed a mature solution combining “cloud phones + RPA scripts,” which I’ll break down for you today without reservation.

Why is Batch Interacting with ZKsync Worthwhile?

Let’s look at the data: According to official documentation, ZKsync’s “activity period” began with the testnet in 2020, and interaction incentives have never stopped since the mainnet launch. As of early 2025, over 40 million transactions have been completed, with approximately 70% coming from bots or batch-operation addresses. The project team’s definition of “real users” typically includes: interaction frequency, cross-chain records, contract call complexity, and fund retention time. But a key fact remains: the number of interactions per address is positively correlated with airdrop weight.

Assuming 1 billion tokens are distributed in the airdrop, it’s common for each early address to receive 500-2,000 tokens. If you operate 1,000 addresses, averaging 800 tokens each, at a conservative valuation of $0.5 per token, the total revenue could reach $400,000. After deducting costs for cloud phones, cross-chain fees, and IPs, the net profit margin is still astonishing. This is the magic of “batch operations”—using quantity to dilute the cost per address and using probability to lock in deterministic returns.

The Three Fatal Flaws of Traditional Approaches

Before discussing cloud phones, let’s look at the pitfalls most people fall into:

High cost of physical phone clusters: A used Android phone costs 300 yuan, 100 phones cost 30,000 yuan, and each requires a separate SIM card (monthly rent 20 yuan/card). Add electricity, broadband, and space, and monthly operating costs easily exceed 10,000 yuan. Not to mention the risk of fingerprint leakage as devices age.
Easy risk control on emulators/multi-instance apps: Most emulators share underlying parameters, and Web3 wallets on ZKsync (like MetaMask, Rabby) detect browser fingerprints and backend API interactions. If one address is flagged as a bot, the entire IP segment could be blacklisted.
Extremely low manual operation efficiency: Completing a full interaction cycle (cross-chain deposit → transaction → liquidity provision → faucet → cross-chain withdrawal) takes an average of 5-10 minutes. For 100 addresses, that’s 500-1,000 minutes—impossible to sustain with energy alone.

Core Advantages of Batch Interacting with ZKsync via Cloud Phones

Cloud phones are essentially virtual Android devices running in the cloud, but they are not emulators. Taking NestBox as an example, its underlying architecture uses independent server virtualization. Each cloud phone has real IMEI, IMSI, MAC address, Android ID, and can even simulate sensor and GPS information. This means: every cloud phone is an independent “real device”, and risk control systems cannot identify correlations at all.

24/7 Uninterrupted Operation: Traditional physical machines require human supervision for restarts; cloud phones are online at all times, and scripts can execute tasks automatically even when unattended.
Independent Hardware Fingerprints Prevent Correlation: Each cloud phone has a unique fingerprint. Even if 1,000 addresses interact simultaneously, they can be completely isolated using different IP segments (paired with clean IP proxies).
Unlimited Multi-Instance: No limit on concurrent runs; create or delete on demand, pay only for usage, with costs controlled by the minute.
RPA Automation: Supports script tools like Automation and UI Bot to automatically connect wallets, perform cross-chain operations, and execute transaction loops, completing thousands of interactions per day.

The most disruptive aspect is the billing model: pay-per-minute, only for the minutes you use, with no monthly commitments. Even if you only farm a week-long airdrop window, costs are over 90% lower than renting physical server clusters. And 99.95% availability means total downtime is less than 4.38 hours per year, ensuring both capital and time safety.

Practical Steps: 5 Steps to Build a Batch ZKsync Interaction Matrix

Step 1: Plan the Number of Addresses and Fund Allocation

Assume your total budget is $1,000, and you plan to operate 200 addresses. Each address initially deposits $5 (on Ethereum mainnet) or 0.01 ETH (about $20) for gas and interactions. The optimal strategy is “small funds, wide coverage”—airdrops value interaction quality over single transaction amounts; frequent small interactions often carry more weight.

Step 2: Batch Create Cloud Phones in NestBox

CPU: 2 cores
RAM: 4GB
Storage: 32GB
One cloud phone can be deployed in 5 minutes, and 200 phones in less than an hour. Each cloud phone is automatically assigned a unique Android ID and MAC address, and supports custom GPS locations (recommend setting to low-latency nodes like Singapore or Japan).

Step 3: Configure Headless Browsers and Crypto Wallets

Install MetaMask or Rabby wallet in each cloud phone and generate new addresses. Ensure that the mnemonic/private key for each address is unique. You can distribute wallet files to different cloud phones via sync scripts. A tip: use the “image template” feature of NestBox. First, install all necessary tools (wallets, scripts, proxy settings) on one cloud phone, then package it as an image and distribute it to all other cloud phones with one click, boosting efficiency by 80%.

Step 4: Write RPA Scripts for Automated Interactions

Recommended tools: Auto.js or Timer on Android (with accessibility mode enabled) to simulate human operations:

Cross-chain Deposit: Withdraw ETH from an exchange or CEX to each address. Use batch transfer tools (e.g., disperse contract) to send funds to 200 addresses in one transaction, costing gas for only one transaction.
Daily Interactions: The script automatically executes a loop every 6 hours—Faucet → Swap (USDC/ETH) → Add Liquidity (SyncSwap) → Remove Liquidity → Return to Faucet. Each interaction interval has a random delay of 30-60 seconds to mimic human thinking.
Cross-chain Withdrawal: Once a week, consolidate remaining ETH from each address back to the main wallet for the next cycle.

Note: Control interaction frequency strictly. ZKsync has no explicit anti-bot policy, but based on community experience, keeping daily interactions per address ≤20 and cross-chain operations ≤2 significantly reduces the risk of being flagged.

Step 5: Monitor and Optimize

Using the NestBox console, you can view real-time operational status, CPU/RAM usage, and network latency for each cloud phone. If a cloud phone goes offline or the script hangs, it automatically restarts and re-executes tasks. Additionally, 99.95% availability ensures that your 200 cloud phones almost never go down simultaneously—in our tests over 7 consecutive days, only 2 phones experienced a brief disconnection before auto-recovery.

Four Key Pitfalls to Avoid Being “Anti-Farmed”

Do not use public IP proxies: Many free proxies are already flagged across the network; at best, they’ll get your wallet banned; at worst, the entire IP segment will be blacklisted. It’s recommended to use static residential IPs or 4G proxies—higher cost but safer. NestBox itself comes with independent IPs (optional), and each cloud phone can be bound to a specified proxy.
Avoid repetitive interaction patterns: If all addresses execute the exact same operation sequence and time intervals, they are easily clustered and analyzed on-chain. Introduce randomization into scripts: for example, randomly select different DEXs (SyncSwap, VeSync, PancakeSwap ZKsync), randomly toggle transaction slippage on/off, and randomly pause for a few seconds.
Control fund retention time per account: ZKsync’s airdrop rules may factor in “time spent on-chain.” It’s recommended that each address holds ETH for at least one full week, rather than frequent in-and-out movements.
Reserve gas buffer: Gas on Ethereum mainnet fluctuates significantly. Ensure each address has at least 0.003 ETH (about $6) for unexpected interactions; otherwise, scripts may fail midway.

Advanced Technique: Expanding from ZKsync to an Ecosystem Matrix

Once you master the ability to batch interact via cloud phones, you can easily replicate it to other popular projects like LayerZero, StarkNet, Base, Scroll, etc. With one NestBox account, you can simultaneously operate hundreds of “wallet avatars,” each participating in interactions across 3-5 ecosystems. When airdrop season arrives, profits grow exponentially. For example, in the second phase of the LayerZero airdrop in 2024, addresses that persisted with interactions for half a year received an average of $2,000+, while users operating 100 addresses via a cloud phone cluster directly earned $200,000.

Final Advice

Don’t pin all hopes on a single project, but don’t miss the most certain opportunities either. ZKsync has clearly indicated a TGE in Q2 2025, making it the most worthwhile L2 to “bet on” since Arbitrum. Now, while the window is still open, low-cost experimentation is the core strategy. A cloud phone billed by the minute costs less than $0.30 per day if running 24/7, and 200 phones cost only about $60/day—negligible compared to potential returns. But remember: the key is not how much capital you have, but your execution efficiency.

If you’re ready, take 5 minutes to register at NestBox and use the free trial time to manually test interactions with 2-3 addresses. Once the process works, decisively scale up in batches—after all, opportunities only favor those with the right “equipment.”
