Last week [**Polygon deprecated its primary PoS testnet, Mumbai**](https://polygon.technology/blog/polygon-pos-is-cooking-the-napoli-upgrade-means-better-ux-the-mumbai-testnet-takes-a-bow). As one of the [**primary users of GSN on Polygon Mainnet and Mumbai**](https://dune.com/rlyrw_1/rally-protocol-gsn-usage/08261ac6-af3c-490f-812a-b49708130132) we wanted to ensure that our partners would have a seamless transition from Mumbai to the new Polygon PoS testnet, Amoy. To that end we have deployed all of the core [**Gas Station Network**](https://opengsn.org/) contracts to Amoy (addresses below), verified the contracts on the new explorer and anyone that wants to can start using them immediately either via [**RallyTransact**](https://docs.rallyprotocol.com/rallyprotocol/rallytransact) or by [**registering your own relayer permissionlessly**](https://docs.opengsn.org/relay-server/tutorial.html). This is just the start of our support for GSN on new EVM chains, expect to see more in the coming months.
