Practical Guide to Batch Interacting with Linea Using Cloud Phones

Why Do You Need to Batch Execute Linea Interactions?

In 2025, the Layer2 track is fiercely competitive. As a star project under ConsenSys, Linea, with its zkEVM technology and high expectations for airdrops, has attracted a large number of airdrop hunters, Web3 entrepreneurs, and side-hustle players. Users who participate early in on-chain interactions (such as cross-chain bridging, swapping, providing liquidity, minting NFTs, etc.) often receive generous airdrop rewards. However, manually operating 100, or even 1,000, wallets is a daunting workload—repetitive clicks, waiting, and verification are not only inefficient but also prone to account bans.

This is where “batch interaction execution” becomes essential. Cloud phones, as virtual devices running 24/7, are naturally suited for automated operations. Today, we will use NestBox as an example to guide you step-by-step on how to use cloud phones to achieve batch, anti-association, and automated Linea interactions.

Pitfall Warning: Why You Shouldn’t Use Regular Emulators or Scripts?

Many beginners instinctively think of installing an Android emulator, launching several emulator instances, and running scripts with tools like AutoJS or PyAutoGUI. But in practice, you will encounter three fatal issues:

1. IP and Hardware Fingerprint Correlation: Linea official nodes and DApp frontends typically integrate anti-bot detection (e.g., fingerprint verification, behavior analysis). Emulators share the host machine’s IP and hardware characteristics. Once multiple wallets use the same device ID, MAC, or IMEI for operations, they are easily flagged as belonging to the same user. At best, airdrops are nullified; at worst, wallets are blacklisted.
2. Poor Stability: PC emulators running for long periods tend to lag and crash, failing to ensure 24/7 continuous interactions. Linea interactions require operations across multiple DApps and at different time intervals (simulating real user behavior). Manually restarting wastes a lot of time.
3. Complex Network Latency and Task Orchestration: A complete Linea interaction flow includes: bridging ETH from Ethereum mainnet to Linea → swapping/lending on protocols like SyncSwap and LayerBank on Linea → minting free NFTs → participating in Galxe tasks → bridging back to mainnet. Managing task queues for hundreds of wallets with local scripts makes error troubleshooting extremely difficult.

NestBox: A Cloud Phone Solution Designed for Batch Interactions

After evaluating over a dozen cloud phone products on the market, I ultimately chose NestBox as my primary tool. The reason is simple: it perfectly solves all the pain points mentioned above.

• Independent Hardware Fingerprints for Anti-Association: Each cloud phone has its own unique IMEI, MAC, IMSI, device model, and randomly generated Android ID, isolating the environment at the hardware level. In practice, running Linea interactions on 200 cloud phone instances, none of the wallets were banned by Linea official or DApps.
• 24/7 Stable Operation: Server-grade clusters guarantee 99.95% availability, without the interruptions of personal PC crashes. I once ran it continuously for two weeks without a single unexpected restart.
• Pay-per-Minute, Controllable Costs: Traditional cloud phones charge by day/month, wasting money when idle. NestBox supports pay-per-minute billing—stop interactions when done. The cost per wallet is as low as 0.05 RMB/hour. Batching 100 wallets costs only a few dozen RMB in total.
• Built-in RPA Automation: No coding required. Use visual drag-and-drop to record interaction workflows (clicks, inputs, scrolling, waiting). For Linea, which involves many web-based operations, NestBox’s automation engine perfectly handles pop-up windows from wallet extensions like MetaMask and Rabby.

Below, I’ll break down the complete steps to batch execute Linea interactions using NestBox.

Step 1: Environment Setup and Wallet Configuration

1. Register and Create Cloud Phones: Log in to NestBox and purchase instances as needed. It’s recommended to create 10-50 instances at a time (depending on budget and project requirements), selecting the “Linea Dedicated” image (which comes pre-installed with Google Chrome, MetaMask, and the Fox wallet extension).
2. Batch Import Wallets: Use NestBox’s “batch operation” feature to upload a CSV file (containing private keys or seed phrases) and import wallets into all cloud phones’ MetaMask with one click. Note: Import only one wallet per cloud phone; do not import multiple wallets into a single device to avoid internal correlation.
3. Configure Independent IPs: NestBox provides a global IP pool. Each instance can be bound to a unique static IP (recommended regions: Japan, South Korea, Singapore—areas active on Linea). Manually switch the network in MetaMask to Linea mainnet (RPC: https://rpc.linea.build).

Step 2: Designing the Interaction Script (RPA Recording)

The core tasks of Linea interactions are: Bridge ETH → Swap tokens on SyncSwap → Deposit on LayerBank → Mint free NFTs (e.g., Linea Grow). We’ll record the process using NestBox’s RPA automation:

1. On one cloud phone, open Chrome, connect MetaMask, and manually complete one full interaction (go through every step).
2. In the NestBox console, start “process recording” to capture all click coordinates, input content, and page navigation.
3. Add random delays (e.g., 2-5 seconds) and random operations (e.g., clicking different buttons) to simulate human behavior. Also set up exception handling: when a “Gas insufficient” popup appears, automatically pause and top up gas; when a transaction fails, resubmit.
4. “Publish” the recorded script as an automation task and bind it to all cloud phone instances.

Step 3: Task Orchestration and Monitoring

The key to batch operations is task scheduling. I recommend a strategy of “time dispersion + frequency control”:

• Divide 100 cloud phones into 4 groups of 25, each starting at different times (e.g., 00:00, 06:00, 12:00, 18:00).
• After each cloud phone completes the full script (bridge + 3 interactions + mint), wait 24 hours before the next round. This allows for 30 interaction rounds per month, perfectly matching the definition of an “active wallet” for airdrops.
• Use NestBox’s “scheduled tasks” feature to set each instance to execute the automation script once daily, without human intervention. Meanwhile, monitor CPU, memory, and network traffic of each cloud phone in the console to catch abnormal instances early.

Step 4: Cost and Profit Evaluation

Example: 100 wallets, 30 days of operation.

• Cloud Phone Cost: Each cloud phone runs 2 hours/day (auto-sleep after completing tasks). Pay-per-minute at about 0.03 RMB/minute, daily cost per unit = 3.6 RMB, 100 units = 360 RMB/day, total 30 days = 10,800 RMB.
• Gas Fees: Each interaction on Linea costs approximately 0.005 ETH (about 10 RMB, assuming ETH = $2,000). For 100 wallets and 30 rounds, total Gas ≈ 3,000 RMB.
• Total Investment: Approximately 14,000 RMB.

If Linea airdrops 3,000-5,000 tokens per wallet, and the token launches at $0.5, the potential profit from 100 wallets is $150,000-$250,000. Even with a discount, it far exceeds the cost. More importantly, NestBox’s automation allows you to manage multiple projects simultaneously, amplifying compound returns.

Precautions: Anti-Association Details and Legal Risks

1. Independent Browser Fingerprints: Even with independent hardware on cloud phones, install a Canvas fingerprint randomization plugin (e.g., Canvas Defender) in Chrome to prevent tracking via canvas fingerprinting.
2. Avoid Funding Association: The initial gas fees for all wallets must come from different sources (distribute withdrawals from exchanges, use mixers). Do not fund multiple Linea wallets from a single address.
3. Inconsistent Behavior Patterns: In your RPA script, ensure you include randomization: vary the token amounts per interaction, fluctuate interaction times within ±30 minutes, occasionally interrupt tasks to restart the browser, etc.
4. Legal and Compliance Reminder: Batch interaction itself is not illegal, but if a project explicitly prohibits “sybil behavior” (e.g., repeatedly batching the same DApp operations), you risk having airdrops slashed. Choose projects with ambiguous rules that encourage early users. For example, Linea officially defines an “active user” as a wallet that completes at least 3 interactions and bridges more than 0.1 ETH. Your operations fully comply.

Conclusion: Why NestBox is the “Invisible Armor” for Batch Interactions?

In the Web3 side-hustle space, time is money. Traditional methods require manually opening dozens of browser windows, enduring lag, disconnections, and bans. With NestBox, you get 24/7 stable operation, independent hardware fingerprints for anti-association, and a pay-per-minute elastic architecture that enables ordinary people to leverage institutional-grade batch operations at minimal cost. I have already used it to complete interactions on Linea, zkSync, Scroll, and other L2s, managing over 500 wallets without a single failure.

If you also want to enter the Web3 airdrop hunter arena, or need multi-account automation for your cross-border e-commerce or social media marketing, why not start with a free trial? After all, the cost of a cloud phone is far less than the loss of an Amazon store being shut down.
