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 is signed and relayed — no SOL needed.

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);
