Launch Wallet Services

The launchWalletServices method launches a WebView which allows you to use the templated wallet UI services. The method takes ChainConfig as the required input. Wallet Services is currently only available for EVM chains.

note

Access to Wallet Services is gated. You can use this feature in sapphire_devnet for free. The minimum pricing plan to use this feature in a production environment is the Scale Plan.
