​
Prerequisite

  • Your dApp uses Wagmi for wallet interactions.
  • If using an auth provider (e.g. Privy, Dynamic), refer to its dedicated Intersend guide.

​
Integration Steps (Wagmi + Safe Example)

Below is the most common scenario: you already use Wagmi and need to ensure the Safe Connector is present so Intersend can auto-connect. If your app relies on Privy or Dynamic for auth, please see those guides.

​
1. Add (or Confirm) Safe Connector

Add the Safe connector to your Wagmi config. If your app already uses the Safe connector, you can skip this step. 
import { createConfig, http } from 'wagmi'
import { mainnet, sepolia, polygon } from 'wagmi/chains'
import { createClient } from 'viem'
import { safe } from 'wagmi/connectors'

export const config = createConfig({
  chains: [mainnet, sepolia, polygon],
  connectors: [
    safe(), // Add Safe connector
    // ... other connectors
  ],
  client({ chain }) {
    return createClient({ chain, transport: http() })
  },
})

​
2. Whitelist Intersend Domain

Since Intersend loads your dApp in an iframe and communicates via postMessage, you must allow the following domains: Required domains:
  • intersend.io
  • *.intersend.io
If you’re using a third-party authentication provider, ensure they also whitelist these domains to enable secure cross-domain communication.

​
3. Verify App Behavior Inside Intersend

  1. Open Sandbox and paste your web app’s URL into the address bar of the Intersend browser.
  2. Auto-connect should kick in; Intersend will inject the user’s wallet data into your app.
  3. Test transaction or signing flows to confirm everything relays properly.

4. Get Listed

Once integrated, submit your app for review:
