here's a list of supported wallet, if you notice a Cardano wallet that support dApp connector is missing, feel free to send a mail here

• Nami
• CCVault
• Flint
• Yoroi
• Gero Wallet
• Typhon
• CardWallet

Usage

basic usage

access a generic wallet

let Typhon = undefined;
const ITyphon = Wallet.getInterface( Wallet.Names.Typhon );

if( 
    ITyphon.isInjected() // equivalent to ```Wallet.has( Wallet.Names.Typhon )```
)
{
    if(
        ITyphon.isAviable() // if enabled before returns true, no need to perform async calls
    )
    {
        Typhon = Wallet.Typhon; // Wallet.get( Wallet.Names.Typhon ) will do the same
    }
}
else // async code needed
{
    if(
        await ITyphon.isEnabled() // @returns {Promise<boolean>} as per CIP0030 definition
    )
    {
        Typhon = Wallet.Typhon; // same as before
    }
    else
    {
        await Wallet.enable( Wallet.Names.Typhon ); // makes the object aviable
        Typhon = Wallet.Typhon; // same as before
    }
}

simple delegation

NOTE: every other wallet will work the same way, just change the name (eg. Nami -> CCVault )

/*... other imports ...*/
import Wallet from "@harmonicpool/cardano-wallet-interface";

/*...*/

if( Wallet.has( Wallet.Names.Nami ) )
{
    if( !await Wallet.isEnabled( Wallet.Names.Nami ) )
    {
        Wallet.enable( Wallet.Names.Nami )
        .then(
            () => {
                Wallet.Nami.delegateTo(
                    "<your pool id>",
                    "<your blockforst api key>"
                );
            }
        );
    }
    else
    {
        Wallet.Nami.delegateTo(
            "<your pool id>",
            "<your blockforst api key>"
        );
    }
}
