Did some tests and leaving some comments:

• this pr won't be merged at this moment, because it will change the default connectors list
• keplr can be already used by initializing the injected connector
  • new InjectedConnector({ options: { id: "keplr" } })
• using starknetkit connect method, it needs to be passed to the connectors option

const res = await connect({
      connectors: [
        new InjectedConnector({ options: { id: "argentX" } }),
        new InjectedConnector({ options: { id: "braavos" } }),
        new InjectedConnector({ options: { id: "keplr" } }),
        new ArgentMobileBaseConnector({
          dappName: "Starknetkit example dapp",
          url: window.location.hostname,
          chainId: CHAIN_ID,
          icons: [],
        }),
        new WebWalletConnector({ url: ARGENT_WEBWALLET_URL }),
      ],
      modalMode: "alwaysAsk",
    })

    const { wallet, connectorData, connector } = res

• discovery is not working for keplr at the moment, we need to wait for @starknet-io/get-starknet-core to be updated for this

[Thunnini]

@bluecco Then, can you leave out the default connectors list part and just add the icon part?

[bluecco]

@Thunnini yes, adding in #142
will do some tests on the pre-release first

[bluecco]

closing this in favour of #142
published new version of starknetkit
can be installed with starknetkit@latest (v2.3.3)

• can connect with keplr
• can send a transaction if the account is deployed

there are 2 issues on wallet side:

• cannot sign a message
• cannot perform a transaction if the account is undeployed
