Polygon Amoy Testnet

The Polygon Amoy testnet is now live on OpenSea. Amoy replaces Mumbai as the Polygon Proof-of-Stake testnet chain based on Sepolia. Mumbai was based on Goerli, which is deprecated.

You can now use the chain amoy in testnet API queries - please be sure you're on the testnets-api.opensea.io subdomain when interacting with Amoy. If you need test MATIC tokens on Amoy, they can be obtained from the Polygon Amoy Faucet by Alchemy.
