Openfort

Overview

Openfort is an open-source alternative to wallet infrastructure solutions. The core offerings—Openfort Kit, Invisible Wallet, and Cross-app Wallet - enable rapid integration of wallet functionality, intuitive onboarding, and flexible user journeys for any application or ecosystem.

Openfort Kit

Openfort Kit is a developer toolkit that streamlines the integration of wallet authentication and connectivity into any web application. It provides:

• Plug-and-play UI Components: Prebuilt, customizable authentication and wallet connection flows that can be deployed in minutes, not weeks, with support for major authentication providers and wallet connector
• Developer Experience: TypeScript-ready, ecosystem-standard libraries (wagmi, viem), and easy integration with frameworks like React, Next.js, and Create React App.
• Full Customization: Predesigned themes or the ability to fully tailor the UI to match your brand.

Invisible Wallet

Invisible Wallet enables applications to onboard users without requiring them to interact directly with traditional wallet interfaces. Features include:

• Embedded Non-custodial Signer: Secure, self-custodied wallet creation and signing for users, with no need for browser extensions or external apps.
• Fundign Support: Users can onramp their newly created wallets with traditional methods or depositing crypto.
• Key Export: Users can always export private keys, allowing them to take the wallet with them.

Cross-app Wallet

The Cross-app Wallet empowers ecosystems and platforms to offer branded, interoperable wallets that work across multiple apps and services. Key capabilities:

• Ecosystem SDK: Build your own wallet SDK that can be integrated across your suite of apps, ensuring users have a consistent identity and asset management experience everywhere.
• No App or Extension Required: Users can create and use wallets instantly via iFrames or embedded flows, compatible with any EVM chain.
• Modern Standards: Supports the latest Ethereum standards (EIP-1193, 6963, 7702, 4337, and more) for broad compatibility and future-proofing.

Getting Started

1. Installation

# Install dependencies
npm install @openfort/openfort-js @openfort/openfort-node
npm install ethers viem

2. Configuration

// Initialize Openfort with client and server configurations
// Client side
const openfortClient = new Openfort({
  baseConfiguration: {
    publishableKey: "YOUR_OPENFORT_PUBLISHABLE_KEY",
  },
  shieldConfiguration: {
    shieldPublishableKey: "YOUR_SHIELD_PUBLISHABLE_KEY",
  },
});
 
// Server side
const openfortServer = new Openfort("YOUR_SECRET_KEY");

3. Basic Implementation

// Authentication
const authResponse = await openfort.logInWithEmailPassword({
  email: "[email protected]",
  password: "password123"
});
 
// Initialize Provider
const provider = await openfort.getProvider();
await provider.request({ 
  method: 'wallet_switchEthereumChain',
  params: [{ chainId: `0x${avalancheChain.id.toString(16)}` }]
});
 
// Create a gas sponsorship policy (server-side)
const policy = await openfortServer.policies.create({
  chainId: 43114, // Avalanche C-Chain
  name: "Gas Sponsorship Policy",
  strategy: {
    sponsorSchema: "pay_for_user"
  }
});
 
// Create transaction intent with sponsorship (server-side)
const transactionIntent = await openfortServer.transactionIntents.create({
  player: "PLAYER_ID",
  chainId: 43114,
  optimistic: true,
  policy: policy.id,
  interactions: [{
    contract: "CONTRACT_ADDRESS",
    functionName: "transfer",
    functionArgs: [recipientAddress, amount]
  }]
});
 
// Sign and send the sponsored transaction (client-side)
const response = await openfortClient.sendSignatureTransactionIntentRequest(
  transactionIntent.id,
  transactionIntent.nextAction.payload.userOperationHash
);
