Features

Three layers between you and a scam

Phishing site blocking

Known scam domains are blocked before they load. Look-alikes and typosquats are caught by on-device heuristics — your browsing never leaves your machine.

Transaction X-ray

Before you sign, Trust Line decodes the request: unlimited approvals, setApprovalForAll, Permit signatures and blind eth_sign are flagged in plain language.

Wallet reputation check

The recipient address is checked against drainer blocklists and its on-chain history — so you know if you are signing over to a known thief.

How it works

Install once, protected everywhere

Add to your browser

One click from the store. No account, no seed phrase, no permissions to your keys.

Browse and transact normally

Trust Line stays invisible until something looks wrong — then it steps in with a clear warning.

Decide with full context

Approve or reject — your keys, your call. Trust Line only advises; it never moves funds or touches your seed.

Privacy by design

Site checks run locally. Trust Line never sees your keys, never asks for your seed phrase, and only sends a domain to our servers when a rule actually fires — never your full browsing history.

FAQ

Frequently asked questions

Is Trust Line free?

Yes. Trust Line is a free browser extension. Core protection — phishing blocking, transaction analysis and signature warnings — works without any account or payment.

Does Trust Line have access to my private keys?

No. Trust Line never sees, stores or asks for your private keys or seed phrase. It reads the transaction request your wallet is about to sign and warns you — the signing itself always happens in your own wallet.

Which wallets does it work with?

Trust Line works with any wallet that injects a standard Web3 provider, including MetaMask, Phantom, Coinbase Wallet, Rabby, Trust Wallet and others, across Ethereum and EVM chains.

What is a wallet drainer?

A wallet drainer is malicious code on a phishing site that tricks you into signing a transaction or approval that lets an attacker move your tokens. Trust Line detects these requests and warns you before you sign.

Does Trust Line track my browsing?

No. Site checks run locally on your device. A domain is only sent to our servers when a protection rule actually fires — never your full browsing history, and never any personal data.

How is Trust Line different from my wallet’s built-in warnings?

Wallet warnings are generic. Trust Line decodes the specific request — unlimited approvals, setApprovalForAll, Permit signatures, blind eth_sign — checks the destination address reputation, and blocks phishing sites at the browser level before the wallet is even opened.
