Alchemy will fully deprecate support for Polygon zkEVM Mainnet (polygonzkevm-mainnet) and the Polygon zkEVM Cardona testnet (polygonzkevm-cardona) on July 1, 2026. After this date, requests to these endpoints will no longer be supported.
Polygon zkEVM is being deprecated because Polygon Labs is shutting down the Polygon zkEVM network on July 1, 2026. Both the mainnet and the Cardona testnet will be sunset by Polygon Labs.
There is no migration path for Polygon zkEVM, as the network itself is being shut down. Before July 1, 2026:
- Remove any dependencies on Polygon zkEVM endpoints (
polygonzkevm-mainnetandpolygonzkevm-cardona) from your applications. - If you are building on a Layer 2, explore Alchemy's other supported chains for an alternative network that fits your needs.
