Polygon Mumbai Support Ending on April 8th - Migrate to Amoy

As of today, we've deprecated support for the Mumbai testnet. This change affects thirdweb’s product and services including the SDK, Paymaster, Embedded Wallet, contracts, and any other products utilizing the Mumbai testnet.

Required Actions for You:

To ensure you can continue testing seamlessly, you will need to migrate to Amoy.

Amoy offers many benefits over Mumbai, including improved scalability and lower gas fees. To learn more about the reasons for deprecation, we recommend reading the official blog post from Polygon: Introducing the Amoy Testnet for Polygon PoS post.

What This Means for You:

  • Unable to deploy contracts: After the deprecation date, you will no longer be able to deploy contracts on Mumbai.
  • Unable to interact with contracts: Interaction with any contracts deployed on Mumbai will no longer be supported via the dashboard, SDKs, or any other interfaces.
  • Disruption to any infrastructure services: Embedded wallets, RPC Edge, and Account abstraction infrastructure including Bundler / Paymaster on Mumbai will no longer be supported.


How do I use the Amoy testnet?

Chain Information:

What will happen to my deployed contracts?

Contracts deployed to Mumbai will no longer be upheld on the network, meaning users cannot interact with the contracts.

How long do I have until services are completely stopped on Mumbai?

We have officially stopped support on April 8th 12:00 AM PST.
