# Polygon zkEVM Deprecation Notice

> Important notice regarding the deprecation of Polygon zkEVM Mainnet and the Cardona testnet

> For the complete documentation index, see [llms.txt](/docs/llms.txt).

## ⚠️ Deprecation Notice

**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](https://polygon.technology/polygon-zkevm). Both the mainnet and the Cardona testnet will be sunset by Polygon Labs.

## What you need to do

There is no migration path for Polygon zkEVM, as the network itself is being shut down. Before July 1, 2026:

1. Remove any dependencies on Polygon zkEVM endpoints (`polygonzkevm-mainnet` and `polygonzkevm-cardona`) from your applications.
2. If you are building on a Layer 2, explore Alchemy's other [supported chains](/docs/reference/node-supported-chains) for an alternative network that fits your needs.
