As of April 14th, 2024, Polygon's Mumbai testnet is no longer functional, and therefore our support for it is discontinued. As a result, note that Mumbai will be removed from your vaults and will no longer be available for you. You are advised to switch to Polygon's Amoy testnet, which is already live and fully operational.
Note:
As a result of this deprecation, any Testnet tokens based on the ETH Goerli network and/or any layer-two networks associated with it (e.g. Polygon Mumbai), as well as any tokens based on either layer-one or layer-two networks (e.g. USDC on Goerli, and USDC on Mumbai), will also be deprecated.
