EVM compatible

This guide will walk you through the process of integrating Kastle with your EVM-compatible decentralized application (dApp) using RainbowKit and wagmi.

Kastle currently only supports Kaia testnet (Kairos) and basic Ethereum methods.

Installation

First, ensure you have the required dependencies:

npm install @rainbow-me/rainbowkit wagmi viem
# or
yarn add @rainbow-me/rainbowkit wagmi viem

Integration

Add the following code to your RainbowKit configuration:

import { getDefaultConfig, Wallet } from "@rainbow-me/rainbowkit";
import { kairos } from "wagmi/chains";
import { injected, createConnector } from "wagmi";

const kastleWallet = (): Wallet => ({
  id: "kastle",
  name: "Kastle",
  iconUrl:
    "https://cms.forbole.com/uploads/Kastle_Symbolic_Logo_27731fc6bd.svg",
  downloadUrls: {
    chrome:
      "https://chromewebstore.google.com/detail/kastle/oambclflhjfppdmkghokjmpppmaebego?authuser=0&hl=en",
  },
  iconBackground: "#FFFFFF",
  createConnector: createKastleConnector(),
});

function getWindowProviderNamespace(namespace: string) {
  const providerSearch = (provider: any, namespace: string): any => {
    const [property, ...path] = namespace.split(".");
    const _provider = provider[property];
    if (_provider) {
      if (path.length === 0) return _provider;
      return providerSearch(_provider, path.join("."));
    }
  };
  if (typeof window === "undefined") return;
  const provider = providerSearch(window, namespace);
  if (provider) return provider;
}

function createKastleConnector() {
  return (walletDetails: any) => {
    const injectedConfig = {
      target: () => {
        const provider = getWindowProviderNamespace("kastle.ethereum");
        if (!provider) {
          return;
        }

        return {
          id: walletDetails.rkDetails.id,
          name: walletDetails.rkDetails.name,
          provider: provider,
        };
      },
    };

    return createConnector((config) => ({
      ...injected(injectedConfig)(config),
      ...walletDetails,
    }));
  };
}

export const config = getDefaultConfig({
  appName: "RainbowKit demo",
  projectId: "YOUR_PROJECT_ID",
  chains: [kairos],
  wallets: [
    {
      groupName: "Popular wallets",
      wallets: [kastleWallet],
    },
  ],
  ssr: true,
});
