Polygon Amoy: Keep Practice POL Separate from Mainnet Funds
Amoy provides a test environment for Polygon applications. The useful outcome of a practice session is a reproducible observation, such as locating a receipt, rather than a claim about the value or production availability of a token.
Recognize the complete test environment
Polygon’s reference gives Amoy chain ID 80002, POL as its gas currency, Sepolia as its parent chain and amoy.polygonscan.com as its explorer. The POL label also appears on Polygon mainnet, whose ID is 137. A mainnet balance and an Amoy balance therefore need separate records. A parent-chain relationship does not mean an Ethereum Sepolia transfer automatically produces test POL on Amoy.
Write an exercise before using a faucet
Choose a concrete question, such as finding the receipt status of an existing Amoy transaction. Record the network, public hash and fields you expect to locate. You can perform that reading exercise without connecting a wallet. If another tutorial requires new test assets, use the faucet reference in Polygon’s current documentation and assess its requirements before proceeding. This page does not operate a faucet, distribute assets or ask for a payment.
Keep development addresses labeled
An application deployed for a test exercise can have a different contract address and different behavior from its production counterpart. Label saved addresses with both chain ID and purpose. For example, “Amoy practice token” is more useful than “USDC” in a scratchpad. Do not copy a test contract into a production receiving flow or treat an attractive test balance as an exchangeable mainnet amount. Test artifacts can also disappear or change as developers revise applications.
Report the limits of a successful observation
A receipt successfully found on Amoy establishes that the explorer reports that particular test action. It does not validate a Base mainnet route, real liquidity, production gas requirements or RunixCoin signing behavior. RunixCoin lists Amoy in the wallet interface, while its public estimates concern Base mainnet and execution remains unavailable. If a practice exercise fails, document which test network and step failed instead of changing production wallet settings or using a funded account to reproduce it.
