Polygon Amoy is the official testnet for Polygon PoS, launched in January 2024 as the successor to Mumbai. Anchored to Ethereum Sepolia, Amoy provides a sustainable, future-proof environment for developers to build, test, and debug dApps before mainnet deployment. This guide covers everything you need: network details, RPC endpoints, how to add Amoy to MetaMask, faucet options, and best practices for choosing a reliable RPC provider.
Whether you're deploying a DeFi protocol, NFT marketplace, or enterprise solution, understanding Amoy's infrastructure is critical. We'll walk through practical steps to get started, including connecting to RPC endpoints, obtaining test POL tokens, and optimizing your development workflow.
Key takeaways
- Polygon Amoy is the official testnet for Polygon PoS, replacing Mumbai and anchored to Ethereum Sepolia.
- Chain ID: 80002; native currency: POL; block explorer: https://amoy.polygonscan.com.
- Public RPC endpoints include https://rpc-amoy.polygon.technology and alternatives from providers like OnFinality.
- Add Amoy to MetaMask using network name 'Polygon Amoy', RPC URL, chain ID 80002, symbol POL, and explorer URL.
- Faucets like Alchemy and OnFinality provide free test POL tokens; rate limits apply.
- Reliable RPC infrastructure is essential for consistent testnet performance; consider dedicated nodes for heavy testing.
- Always test smart contracts and dApps on Amoy before mainnet deployment to avoid costly errors.
What Is Polygon Amoy Testnet?
Polygon Amoy is the official testnet for the Polygon PoS chain, launched on January 12, 2024 by Polygon Labs. It replaces the Mumbai testnet, which relied on the deprecated Goerli testnet. Amoy uses Ethereum Sepolia as its root chain, ensuring long-term support and alignment with Ethereum's development roadmap.
The testnet provides a low-stakes environment where developers can deploy smart contracts, test dApps, simulate transactions, and identify vulnerabilities without risking real assets. It closely mirrors Polygon mainnet in terms of block time, gas mechanics, and supported features.
- Chain ID: 80002
- Native token: POL (testnet)
- Block explorer: https://amoy.polygonscan.com
- Root chain: Ethereum Sepolia
- Consensus: Proof-of-Stake (same as mainnet)

Polygon Amoy RPC Endpoints
To interact with the Amoy testnet, you need an RPC endpoint. Below are common public endpoints and how to connect via providers like OnFinality.
Public endpoints are free but may have rate limits and variable performance. For production-grade testing, consider a dedicated RPC provider.
- Public RPC: https://rpc-amoy.polygon.technology
- OnFinality RPC: Available via API service (see CTAs)
- Other providers: Alchemy, Infura, QuickNode
| Criterion | What to check | Why it matters |
|---|---|---|
| Endpoint | URL | The URL you use to connect to the network. |
| Rate Limits | Requests per second (RPS) | Free endpoints may throttle; dedicated nodes offer higher limits. |
| Uptime | Service level agreement (SLA) | Reliable uptime ensures consistent testing. |
| Geographic Distribution | Server locations | Closer nodes reduce latency. |
For high-throughput testing, consider a dedicated Polygon Amoy node. OnFinality offers dedicated nodes with guaranteed performance. Explore Dedicated Nodes.
How to Add Polygon Amoy to MetaMask
Adding Polygon Amoy to MetaMask allows you to manage test POL tokens and interact with dApps. Follow these steps:
- Open MetaMask and click the network dropdown at the top.
- Select 'Add Network' (or 'Custom Network' depending on version).
- Enter the following details:
- Network Name: Polygon Amoy
- New RPC URL: https://rpc-amoy.polygon.technology (or your preferred endpoint)
- Chain ID: 80002
- Currency Symbol: POL
- Block Explorer URL: https://amoy.polygonscan.com
- Click 'Save'. The network will be added and automatically selected.

Getting Test POL Tokens (Faucets)
To deploy contracts and pay gas fees on Amoy, you need test POL tokens. Several faucets provide free tokens:
- Alchemy Polygon Amoy Faucet: https://www.alchemy.com/faucets/polygon-amoy (0.1 POL per day, no authentication required)
- OnFinality Faucet: Available through the OnFinality platform (check dashboard)
- Other community faucets: Search for 'Polygon Amoy faucet' for additional options.
- Note: Faucets typically have rate limits (e.g., one request per 24 hours per wallet).
OnFinality supports Polygon Amoy and many other testnets and mainnets. View the full list. View Networks.
Best Practices for Using Polygon Amoy
To maximize your testing efficiency, follow these best practices:
- Use a dedicated RPC endpoint for heavy testing to avoid rate limits.
- Monitor gas usage and optimize contracts before mainnet.
- Test all critical paths: token transfers, contract interactions, and edge cases.
- Use a separate wallet for testnet to avoid confusion with mainnet funds.
- Regularly check the Amoy block explorer for transaction status and network health.
Choosing a Reliable RPC Provider for Amoy
While public endpoints are convenient, they may not be suitable for extensive testing or CI/CD pipelines. A reliable RPC provider offers higher throughput, better uptime, and dedicated support.
OnFinality provides Polygon Amoy RPC endpoints as part of its multi-chain API service. With global infrastructure and flexible pricing, it's a solid choice for developers who need consistent performance.
- Look for providers with transparent SLAs and multiple endpoint options.
- Consider dedicated nodes if your project requires guaranteed resources.
- Evaluate pricing models: pay-as-you-go vs. subscription.
