# Polygon zkEVM Deprecation Notice

> Notice regarding the ended support for Polygon zkEVM Mainnet and the Cardona testnet

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

## ⚠️ Deprecation Notice

**Alchemy ended support for Polygon zkEVM Mainnet (`polygonzkevm-mainnet`) and the Polygon zkEVM Cardona testnet (`polygonzkevm-cardona`) on July 1, 2026.** Requests to these endpoints are no longer supported.

Alchemy ended support because [Polygon Labs shut down the Polygon zkEVM network on July 1, 2026](https://polygon.technology/polygon-zkevm). Both the mainnet and the Cardona testnet were sunset by Polygon Labs.

## What you can do

There is no migration path for Polygon zkEVM, as the network itself was shut down. 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.
