One platform, a growing family of protection
sadhutech builds security products for the moments you're most exposed. GENESIS, our crypto transaction firewall, is live today. Everything else below is where we're headed next.
Live today
GENESIS - for crypto
GENESIS isn't one single thing - it's three ways to get the same community-verified verdict before you sign.
GENESIS Check
Paste any address or transaction at /check and get a plain-English verdict in seconds. Free forever; Pro adds deeper checks per credit.
Check a transaction →GENESIS Extension
Install it once and any site that asks your wallet to sign something gets screened first - works with MetaMask, Trust Wallet, Coinbase Wallet, and other popular wallets. Available today as a manual install while it goes through browser store review.
Get the Extension →GENESIS Wallet Guard
The broader vision: automatic, real-time protection built into any wallet or browser. GENESIS Extension is the first concrete step toward it.
See the vision →What each surface can actually see
Any browser extension can only screen transactions a website asks your wallet to sign - it can't reach into another extension's own sandboxed UI, like a wallet's built-in swap/send screens.
| Dapp-initiated transactions | Wallet's own native swap/send | |
|---|---|---|
| GENESIS Extension (any wallet) | Protected | Not visible - can't intercept |
What GENESIS protects - and what it can't
Protected: anything your own self-custody wallet (MetaMask, Trust Wallet, Coinbase Wallet, etc.) is asked to sign by a website - a DeFi swap, an NFT purchase, connecting to a new dapp. This works the same way no matter which token or chain is involved, because it's about how the transaction is created, not what it moves.
Not protected: transfers from a custodial exchange app (Robinhood, Coinbase's exchange, Binance, Kraken, etc.). Those platforms hold your funds and send them from their own backend - there's no wallet-signing step in your browser for anything to screen. Same for non-EVM chains like Bitcoin or Dogecoin, and a wallet's own built-in swap/send screens (see the table above).
What's next
Beyond crypto
The same pre-sign, pre-click philosophy applies anywhere you're one wrong action from a bad day. These are early roadmap items, not funded or scheduled yet - see Vision & Roadmap for the full thinking.
Mobile Device Protection
Screening risky links, permissions, and installs on your phone before they cause damage.
Planned - not startedLaptop Protection
The same pre-action firewall model, applied to files, downloads, and scripts on your computer.
Planned - not startedSaaS Protection
Catching risky OAuth grants, integrations, and permission changes across the SaaS apps your team uses.
