How it works

Between the dApp
and your wallet

SignSafe wraps your wallet's sign function. You never change how you use dApps — it intercepts silently, analyzes, and shows you what's coming.

01
⚡

Intercept

When any dApp calls signTransaction, SignSafe catches it before the wallet popup opens.

02
🔬

Simulate

The transaction runs through Solana's RPC to reveal exact balance changes, token flows, and every program called.

03
🧠

Explain

Automated analysis translates raw simulation traces, flags risk signals, and returns a clear verdict — proceed or block.

The problem

Wallets show one line.
We show everything.

Phantom says "Swap." What's actually inside? Three instructions, two program calls, and a hidden SOL transfer to an address you've never seen.

The Crypto Copilot Chrome extension stole from thousands of Solana traders in 2024 by injecting a hidden fee into every swap. The wallet UI showed nothing unusual. SignSafe would have flagged it immediately.

FAQ

Critical questions.
Clear answers.

Real questions from people evaluating whether to trust this extension.

SignSafe Extension is fully open source. Check the code yourself.

No. Your keys never leave your wallet.

Two calls, both visible in the source. The transaction goes to Solana's public RPC for simulation. The simulation output — instruction set, balance deltas, program invocations — is passed to the analysis engine. No keys, no wallet addresses, no browsing history.

Wallet warnings are good — keep them on. Wallet services rely on catalogued threat signatures. SignSafe runs live on-chain simulation against every transaction — known or not. A zero-day drainer with no prior history gets flagged the moment simulation shows tokens draining.

Any browser wallet — Phantom, Backpack, Solflare.
