We don't support the chainId you provided: eip155:1338

[aqeelVaival]

I am using web3-react v8, i know its not web3-react platform but still indirectly issue seems to be related with walletConnect, so Custom chain with id 1338 for testnet & 1339 for mainnet with Metamask are working fine with web3-react v8. But with walletConnect V2 only default selection works with already reputable network, not working with 1338 & 1339 , stating the error

{"status":"FAILED","reasons":[{"field":"chainId","description":"We don't support the chainId you provided: eip155:1338"}]}

Screenshoot attached as well... Is there any platform of walletConnect where we need to register the 1338/1339 evm chains? & after that only can we able to connect metamask using walletConnect v2? Please guide

I'm not that familiar with web3-react, does it let you add optional / required chains? Also which wallet are you using?

[aqeelVaival]

yes, using metamask...
Specifically for walletconnect v2 , does it need to register chain to walletconnect officials inorder to use it?

[glitch-txs]

I'm able to connect to MetaMask to 1338 chain with WalletConnect v2. I'd suggest opening an issue on web3-react repo

[aqeelVaival]

Added chain.ts file above

[aqeelVaival]

I already raised issue there, could you please help share the code you used to connect? & Which wallet app?

I use this one for testing you can change the config to any chain there and try.

but it's basically the ethereum-provider implementation

[aqeelVaival]

ok sure i will check & update, thanks

[aqeelVaival]

yes @glitch-txs you are right, issue seems to be at web3-react library side...Thanks alot man.
