Live on Solana Devnet

2FA for every
Solana transaction

Confirm from your phone. Execute from your browser.
If the frontend is compromised, your funds stay safe.

How It Works

Two devices. One hash. Zero trust.

Like Google Authenticator, but for blockchain transactions instead of logins.

Step 1 — Trusted Device

📱

Confirm on Mobile

Scan the QR code from your dApp. See exactly what you're approving — amount, destination, slippage. Confirm with biometrics. The intent hash is committed on-chain.

Step 2 — Browser

💻

Execute Transaction

The dApp detects your on-chain commit and adds a verify instruction. If parameters match your intent — transaction goes through. If not — it reverts. Atomic.

Security

What happens when the frontend is hacked?

The attacker controls your browser. They change the swap amount from 1 SOL to 100 SOL.

Without IntentGuard

            You see: Swap 1 SOL → USDC

            Actually: Swap 100 SOL → USDC

            Phantom: "Approve Transaction?"

            You: *clicks approve*

            Result: 100 SOL gone.

With IntentGuard

            Phone committed: hash(1 SOL)

            Attacker sends: hash(100 SOL)

            hash(1 SOL) ≠ hash(100 SOL)

            TX REVERTS. Funds safe.

For Developers

Add 2FA to your dApp in 3 lines

No program changes needed. Just prepend a verify instruction to your existing transaction.

# TypeScript
npm install intentguard-sdk

# Rust (CPI)
cargo add intentguard-cpi

// Build your normal transaction
const swapIx = buildJupiterSwap(params);

// Add IntentGuard verification (1 line)
const verifyIx = createVerifyIntentInstruction(user, appId, hash);

// Send as atomic transaction
const tx = new Transaction().add(verifyIx).add(swapIx);

Use Cases

Works with any Solana transaction
