Apologies if this is a silly question, but I've searched around and have found no obvious way to select an Ethereum testnet while developing an application to support Coinbase Wallet. Am I missing something obvious or is only Mainnet supported? Thanks

This is something I wanted to find out myself and found a solution for both the mobile and the desktop chrome wallet.

on the Desktop Coinbase Wallet you can switch to a testnet with below steps:

  • Open the settings from the top right
  • Enable the Developer Mode checkbox
  • In settings under 'Default Network' you can now find a section with multiple testnets

For the coinbase mobile wallet:

  • Open Settings in the bottom right
  • Open Advanced Settins
  • Switch Network from Mainnet to Testnet
  • Go back to settings and choose testnet under 'Default Network' setting

In both examples I am referring to the non-custodial wallets from Coinbase, not the managed custodial wallet apps.

You cannot. Most mobile wallets do not support testnets.

For different wallets, check this answer. For mobile wallets supporting testnet, ask help in WalletConnect Discord.
