We are excited to announce support for Polygon Amoy, a Sepolia-based test network for the Polygon Proof-of-Stake \(PoS\) blockchain.

[On January 12, Polygon announced the Amoy testnet](https://polygon.technology/blog/introducing-the-amoy-testnet-for-polygon-pos) as an alternative to Polygon’s Mumbai testnet. When Ethereum deprecates the Goerli testnet, Mumbai will also be deprecated.

We encourage all developers to migrate to the Polygon Amoy testnet as it will be the sustainable path forward for all testing and development needs.

Note: All features supported by Alchemy on Mumbai are also supported on Amoy.

Follow these 5 steps to migrate from Mumbai to Amoy:

1. [Create a new app](https://dashboard.alchemy.com/apps?showModal) from the Alchemy dashboard on the Polygon Amoy network.
1. Get free Amoy tokens from Alchemy's public [Amoy Faucet](https://www.alchemy.com/faucets/polygon-amoy) which drips up to 1 Amoy MATIC per day.
1. Change your `API\_URL` to your Amoy RPC URL: `https://polygon-amoy.g.alchemy.com/v2/\[YOUR-API-KEY\]`
1. Deploy your test contract to Amoy.
1. Change your tests to use the new contract.
