pls provide info on which application you’re connecting to.
The error tells me that app doesn’t support the chains you’re whitelisting in walletconnectv2adapter initialization

Hi Chai, Thank for the response.
I am using binance smart chain in my application and trying to run it on my local system.
Its able to connect with metamask and openlogin.

Hi @chai ,
I got it, the problem was with ethereum chain, its not supported i think. I tried with only 56 chain id, it worked but now its not able to sign personal message correctly with trustwallet. Recovering address from signature is giving different address from the address which actually signs the transaction
