💜Polygon PoS Guide

🚀 About the Polygon Network

Polygon PoS remains the most widely adopted Ethereum sidechain scaling solution. Following the massive Polygon 2.0 upgrade, the network has officially migrated its native Gas token from MATIC to POL.

• Modular Tech Stack: The ecosystem now offers a comprehensive suite of scaling solutions, including ZK scaling (e.g., Polygon zkEVM), Polygon CDK (for building custom L2s), and the AggLayer (for seamless cross-chain interoperability and unified liquidity).

• User Value: For both users and developers, Polygon remains one of the premier choices for deploying applications and issuing assets at extremely low cost.

SlerfTools is fully integrated with Polygon. We cover the entire lifecycle: Token Launches, Airdrops, Trading, and Wallet Management.

⚠️ Note on Network Switching:

This page provides the Network Parameters to switch to Polygon. Once you have switched networks, the workflow is identical to BSC.

Please note: Although tutorial screenshots may show the BSC interface for reference, the steps on Polygon remain exactly the same. Simply follow the standard process.

⚙️ Step 1: Node & RPC Configuration

🌟 Important Update: Please ensure your wallet and code logic are fully adapted to the POL token.

Note: While the legacy MATIC ticker may still persist visually in some older wallet interfaces, the underlying asset used for on-chain interactions is now POL.

Quick Parameters:

• RPC URL: https://polygon-rpc.com/

• Chain ID: 137

• Currency Symbol: POL (formerly MATIC)

• Explorer: https://polygonscan.com

🛠 Step 2: Core Features Guide

SlerfTools has been fully upgraded to support the Polygon POL token standard along with advanced wallet management features.

General Usage Note (Must Read)

To streamline maintenance, the tutorials below may use BSC (Binance Smart Chain) interface screenshots for demonstration. The logic on Polygon is identical!

👉 You simply need to:

1. Follow the steps outlined in the guide.

2. Mentally replace any "BNB" shown in the screenshots with your current POL.

3. Ensure your wallet is connected to Polygon Mainnet (Chain ID: 137).

🪙 Token Launch

Create Standard Token (Polygon ERC20)

• Deploy tokens with minimal gas fees. Fully compatible with OpenSea and all major DEXs.

• 👉 View Token Launch Tutorial

Create Vanity Token

• Generate contract addresses starting with specific characters (e.g., 0x8888... or 0xABCD...) to showcase your unique brand identity.

• 👉 View Vanity Contract Tutorial

👛 Wallet Management (Wallet Tools)

Batch Wallet Generator

• Generate 100+ fresh Polygon wallet addresses and private keys in a single batch. Supports export to Excel and other formats.

• 👉 View Batch Generation Tutorial

Vanity Wallet Generator

• Algorithmically compute your own personalized wallet address (e.g., 0xMyName...).

📦 Batch Operations (Batch System)

Multi-Sender (Distribute)

• Distribute POL or ERC20 tokens to hundreds or thousands of addresses. Ideal for airdrops and mass transfers.

• 👉 View Multi-Sender Tutorial

Asset Collection (Consolidate)

• Consolidate scattered assets (POL/USDT) from hundreds of wallets into a single main wallet with one click. An essential tool for fund sweeping and treasury organization.

• 👉 View Asset Collection Tutorial

📈 Market Management

Batch Trading

• Synchronize buy or sell actions for a specific token across multiple wallets. Execute trades in bulk using unified parameters for efficient management.

⛽️ Gas Fees & Optimization (POL)

Polygon utilizes an EIP-1559 based fee mechanism. While the network can experience occasional congestion, it remains one of the most cost-effective ecosystems in Web3.

1. Cost Structure

• Standard Transactions: Fees are paid in POL. The average interaction cost typically ranges between $0.01 - $0.05, a fraction of the cost on Ethereum Mainnet.

• High Throughput: The PoS mechanism supports massive concurrency. However, please note that Gas Prices may spike briefly during periods of high activity, such as viral On-chain Gaming events or Inscription minting frenzies.

2. How to Acquire Gas (POL)

• Official Bridge (Polygon Portal): Bridge ETH or ERC20 tokens from Ethereum Mainnet to Polygon, then swap them for POL via a DEX.

• Exchanges (CEX): Major exchanges like Binance, OKX, and Coinbase support direct withdrawals of POL to the Polygon network.

• Cross-Chain Aggregators: We recommend using Jumper or Socket. These platforms automatically find the best rates and routes to bridge assets from L2s (like Arbitrum or Base) directly into POL on Polygon.

3. Gas Saving Tips

• Monitor Base Fee: Use a Gas Tracker extension to monitor network traffic. Try to avoid operating during congestion windows when the Base Fee exceeds 100 Gwei.

• Batch Efficiency: SlerfTools' smart contracts are deeply optimized. Executing operations in batch mode can save over 40% on Gas compared to performing manual transfers one by one.

❓ Polygon Specific FAQ

Why does my wallet still show MATIC instead of POL?

The token upgrade occurred at the underlying contract level. Many older versions of wallets (like MetaMask or TrustWallet) simply haven't updated their UI tickers yet.

Rest assured: As long as your Chain ID is 137, the "MATIC" in your wallet is effectively POL. The value is 1:1, and it works perfectly for paying Gas fees.

Is Polygon PoS the same as Polygon zkEVM?

No, they are two completely different chains.

• Polygon PoS (Chain ID 137): The mature sidechain covered in this guide. It uses POL for Gas.

• Polygon zkEVM (Chain ID 1101): A newer Layer 2 ZK-Rollup solution. It uses ETH for Gas.

⚠️ Crucial: Always verify the target network before depositing funds.

Why does the Official Bridge take so long?

The official Polygon Bridge relies on the Plasma/PoS Checkpoint mechanism.

• Deposits: Typically take 20-30 minutes.

• Withdrawals (to Ethereum): Can take 1-3 hours (or longer) for security checkpoints to finalize.

• Pro Tip: If you need speed, use Third-Party Bridges (like Orbiter) or deposit to a CEX and then withdraw to the target chain.

Does creating a "Vanity Token" cost extra Gas?

No. Generating the vanity address itself is an Off-chain Calculation that uses your computer's CPU power, which costs zero Gas. You only pay the standard Gas fee when you find an address you like and click Deploy to publish it on-chain.

Is "Asset Collection" (Sweeping) safe? Do I need to enter my Private Key?

Asset collection requires either Token Approvals or Private Key signatures to move funds from sub-wallets.

Security Logic: SlerfTools uses Client-Side Local Signing. Your private keys are processed locally in your browser and are never uploaded to any server.

Recommendation: We suggest using this feature primarily for high-frequency/burner wallets. For your main treasury, please manage funds in conjunction with a Hardware Wallet.
