Polygon MATIC: Nâng cấp mạng

The next upgrade for Polygon zkEVM will, effectively, make the network a Type 2 ZK-EVM. What does that mean for developers? It means that you can deploy your code on Polygon zkEVM exactly as it is on Ethereum—just copy-paste and go, no modifications necessary.

The 10-day timelock for the Etrog upgrade has been triggered, and devs can test it now on Cardona, the new Sepolia-anchored testnet for Polygon zkEVM.

How to connect to Cardona:
Network Name: Polygon zkEVM Cardona Testnet
Bridge UI: https://bridge-ui.cardona.zkevm-rpc.com/
New RPC URL: https://rpc.cardona.zkevm-rpc.com/
Chain ID: 2442
Currency symbol: ETH
Block Explorer: https://explorer-ui.cardona.zkevm-rpc.com/
Faucet: https://faucet.polygon.technology/

For more on the upgrade, including how to independently verify the source code and what steps infra devs will need to take once Etrog is live on mainnet, check out the blog: https://polygon.technology/blog/the-etrog-upgrade-is-on-testnet-making-polygon-zkevm-fully-type-2

A note for end users: Once the Etrog upgrade is live on mainnet, no action is needed to continue using Polygon zkEVM.
