Usage
No extra configuration is needed. If the user has Backpack installed, it will be detected automatically:
<WankmiProvider endpoint="https://api.mainnet-beta.solana.com">
<App />
</WankmiProvider>Backpack injects itself at window.backpack, separate from window.solana. This means it won't conflict with Phantom if both are installed.
