Network name: Polygon main network (name can be customized)

RPC address: https://rpc-mainnet.matic.network

Chain ID: 137

Symbol: MATIC

URL: (the translation of metamask here is wrong, it is actually the browser) https://explorer-mainnet.maticvigil.com

If it doesn’t work or the network is very stuck, you can choose the following RPC to replace:

https://rpc-mainnet.matic.network

https://rpc-mainnet.maticvigil.com

https://rpc-mainnet.matic.quiknode.pro

https://matic-mainnet.chainstacklabs.com

https://matic-mainnet-full-rpc.bwarelabs.com

https://matic-mainnet-archive-rpc.bwarelabs.com
