InterwovenKit provides a native React integration for connecting and interacting with Initia wallets. This guide covers everything from basic setup to advanced features like transaction handling and cross-chain bridging.

​
Prerequisites

Before integrating InterwovenKit, ensure you have:
  • A React application (Next.js or Vite)
  • Node.js 22+ installed
  • Basic familiarity with React hooks and TypeScript

​
Installation & Setup

Follow these steps to set up InterwovenKit in your application:
1

Install InterwovenKit

Install the core InterwovenKit package and its peer dependencies:
npm install @initia/interwovenkit-react wagmi viem @tanstack/react-query
These packages provide:
  • @initia/interwovenkit-react: React hooks and components for Initia wallet integration
  • wagmi: Ethereum wallet infrastructure (required for cross-chain compatibility)
  • viem: Low-level Ethereum interaction library
  • @tanstack/react-query: Data fetching and state management
2

Configure Providers

Create a providers component to set up the required React contexts. This component wraps your app with the necessary providers for wallet functionality:
providers.tsx
"use client"

import { PropsWithChildren, useEffect } from "react"
import { createConfig, http, WagmiProvider } from "wagmi"
import { mainnet } from "wagmi/chains"
import { QueryClient, QueryClientProvider } from "@tanstack/react-query"
import { initiaPrivyWalletConnector, injectStyles, InterwovenKitProvider } from "@initia/interwovenkit-react"
import InterwovenKitStyles from "@initia/interwovenkit-react/styles.js"

const wagmiConfig = createConfig({
  connectors: [initiaPrivyWalletConnector],
  chains: [mainnet],
  transports: { [mainnet.id]: http() },
})
const queryClient = new QueryClient()

export default function Providers({ children }: PropsWithChildren) {
  useEffect(() => {
    // Inject styles into the shadow DOM used by Initia Wallet
    injectStyles(InterwovenKitStyles)
  }, [])

  return (
    <QueryClientProvider client={queryClient}>
      <WagmiProvider config={wagmiConfig}>
          <InterwovenKitProvider defaultChainId="YOUR_CHAIN_ID">{children}</InterwovenKitProvider>
      </WagmiProvider>
    </QueryClientProvider>
  )
}
Chain Configuration: Replace YOUR_CHAIN_ID with your target blockchain network:
  • "interwoven-1" for Initia mainnet (default)
  • "initiation-2" for Initia testnet
  • Or any valid chain ID from the initia-registry
This sets the primary network for transactions, balance queries, and serves as the default for all operations. See the InterwovenKitProvider reference for details.
3

Wrap Your Application

Import and use the providers in your application root:
layout.tsx
import Providers from "./providers"

export default function RootLayout({
  children
}: Readonly<{
  children: React.ReactNode
}>) {
  return (
    <html lang="en">
      <body>
        <Providers>{children}</Providers>
      </body>
    </html>
  )
}
For other React frameworks, wrap your app component with the Providers component at the highest level possible.

Implement Wallet Connection

Create a basic component that demonstrates wallet connection. This component showcases the core wallet connection functionality using InterwovenKit’s hooks:
components/WalletConnection.tsx
"use client"

import { truncate } from "@initia/utils"
import { useInterwovenKit } from "@initia/interwovenkit-react"

export default function WalletConnection() {
  const {
    address,
    username,
    isConnected,
    openConnect,
    openWallet
  } = useInterwovenKit()

  if (!isConnected) {
    return (
      <div>
        <h2>Connect Your Wallet</h2>
        <p>Connect your Initia wallet to get started</p>
        <button onClick={openConnect}>Connect Wallet</button>
      </div>
    )
  }

  return (
    <div>
      <h2>Wallet Connected</h2>
      <p>Address: {address}</p>
      {username && <p>Username: {username}</p>}
      <button onClick={openWallet}>
        {truncate(username ?? address)}
      </button>
    </div>
  )
}
5

Add Transaction Functionality

Extend your component to handle transactions. This example demonstrates how to send a basic token transfer:
components/TransactionExample.tsx
"use client"

import { useState } from "react"
import { MsgSend } from "cosmjs-types/cosmos/bank/v1beta1/tx"
import { useInterwovenKit } from "@initia/interwovenkit-react"

export default function TransactionExample() {
  const { address, requestTxBlock } = useInterwovenKit()
  const [isLoading, setIsLoading] = useState(false)
  const [lastTxHash, setLastTxHash] = useState<string>("")

  const sendTransaction = async () => {
    if (!address) return

    setIsLoading(true)
    try {
      // Create a simple send transaction to yourself
      const messages = [{
        typeUrl: "/cosmos.bank.v1beta1.MsgSend",
        value: MsgSend.fromPartial({
          fromAddress: address,
          toAddress: address,
          amount: [{ amount: "1000000", denom: "uinit" }], // 1 INIT
        }),
      }]

      const { transactionHash } = await requestTxBlock({ messages })
      setLastTxHash(transactionHash)
      console.log("Transaction successful:", transactionHash)
    } catch (error) {
      console.error("Transaction failed:", error)
    } finally {
      setIsLoading(false)
    }
  }

  if (!address) {
    return <p>Please connect your wallet first</p>
  }

  return (
    <div>
      <h3>Send Transaction</h3>
      <button
        onClick={sendTransaction}
        disabled={isLoading}
      >
        {isLoading ? "Sending..." : "Send 1 INIT to Self"}
      </button>
      {lastTxHash && (
        <p>Last transaction: {lastTxHash}</p>
      )}
    </div>
  )
}

Custom Fee Handling (Optional)

The custom fee handling feature allows you to bypass the “Confirm tx” modal and provide pre-calculated fees directly, giving you more control over transaction speed and UX. The requestTx functions are still available, so you can choose the workflow that fits your app best.You can provide fees in two ways:
  • Pre-calculated: Provide a fixed fee if you are confident.
  • Estimated: Use estimateGas to simulate the required fee.
Since this skips the standard fee selection UI, ensure the fee is displayed somewhere else in your app to maintain transparency for users.
components/TransactionExampleWithFee.tsx
 "use client"

import { useState } from "react"
import { MsgSend } from "cosmjs-types/cosmos/bank/v1beta1/tx"
import { calculateFee, GasPrice } from "@cosmjs/stargate"
import { useInterwovenKit } from "@initia/interwovenkit-react"

export default function TransactionExample() {
  const { address, estimateGas, submitTxBlock } = useInterwovenKit()
  const [isLoading, setIsLoading] = useState(false)
  const [lastTxHash, setLastTxHash] = useState<string>("")

  const sendTransaction = async () => {
    if (!address) return

    setIsLoading(true)
    try {
      // Create a simple send transaction to yourself
      const messages = [{
        typeUrl: "/cosmos.bank.v1beta1.MsgSend",
        value: MsgSend.fromPartial({
          fromAddress: address,
          toAddress: address,
          amount: [{ amount: "1000000", denom: "uinit" }], // 1 INIT
        }),
      }]

      // Estimate gas and calculate fee
      const gas = await estimateGas({ messages })
      const fee = calculateFee(gas, GasPrice.fromString("0.015uinit"))
      const { transactionHash } = await submitTxBlock({ messages, fee })
      setLastTxHash(transactionHash)
      console.log("Transaction successful:", transactionHash)
    } catch (error) {
      console.error("Transaction failed:", error)
    } finally {
      setIsLoading(false)
    }
  }

  if (!address) {
    return <p>Please connect your wallet first</p>
  }

  return (
    <div>
      <h3>Send Transaction</h3>
      <button
        onClick={sendTransaction}
        disabled={isLoading}
      >
        {isLoading ? "Sending..." : "Send 1 INIT to Self"}
      </button>
      {lastTxHash && (
        <p>Last transaction: {lastTxHash}</p>
      )}
    </div>
  )
}
