Overview - For Wallets & WaaS

Integrate apps into a wallet

Turn your wallet into a Web3 gateway using Interspace's universal connector. Embed dApps directly into your interface while maintaining full control over security and user experience.

Why Interspace?

  • Zero Maintenance New apps become automatically available to your users - no integration work required
  • Security First All transactions use your existing signing infrastructure - keys never leave your environment
  • Customizable Curation Choose which apps to display and control their presentation

How It Works

Under the hood, Interspace provides an iframe-based connector that mediates communication between your wallet and apps available on Intersend. Your wallet remains in control of signing, transaction approvals, and chain selection while Interspace relays messages securely via postMessage.

Security Architecture

The SDK implements a secure messaging protocol between the embedded app and your wallet:

  • Isolated Iframes: All third-party dApps are sandboxed within an iframe managed by Interspace. This prevents unauthorized access to your code or your users' private keys.

  • No Private Key Exposure: Any signature or transaction request is forwarded to your wallet's internal signing logic. Keys never leave your environment.

  • Origin Validation: The Interspace SDK verifies the origin of incoming messages. Suspicious or unknown sources are ignored.
