When trying to connect dApp with Fireblocks via WaleltConnect v2 via web link, connection does not happen and an error appears in the browser console

create_wallet_connect:1     Failed to load resource: the server responded with a status of 500 ()
instrument.js:111 NetworkServiceError: Failed fetching "https://sb-console-api.fireblocks.io/create_wallet_connect", status:500

    at async pF.createConnection (Api.ts:1383:5)
    at async DesktopLinking.tsx:38:13

Here is the error from browser console on Fireblocks Console

And just to add more context, WalletConnect seems to do it’s job and the link to connect is valid, because I see this Fireblocks UI for a minute, then it errors out without connecting me:

Hi @S_V

The problem is that the dApp includes a mainnet network as a required namespace in the v2 session proposal. Since the Sandbox is limited to testnet assets only, any connection that requires a wallet for a mainnet network is rejected. For testing purposes, it is recommended to use dApps which have dedicated testnet interfaces, such as https://testnets.opensea.io/.

Hi @alec, thank you for the tip, In our WalletConnect configuration we have available chains set as chains=[goerli, mainnet] –– should it be just chains=[goerli] to work?

Does this mean that in production Fireblocks, only chains=[mainnet] is allowed, and WalletConnect configured as chains=[goerli, mainnet] will error out?

Continuing the discussion from WalletConnect v2/v3 connection via web link does not work for Fireblocks Sandbox:

I am having the same issue, and only have the goerli chain

Were you able to resolve this?

Not yet was able to resolve this @tomniermann
Please describe your setup, so that maybe @alec can give us a tip how to better triage
