Trust Line

Trust Line — your Web3 security agent. Blocks phishing sites and warns about dangerous wallet signatures before you approve them.

Trust Line — Your Web3 Security Agent. Stop wallet drainers before you sign. ═══════════════════════════════════════ It always starts the same way. You're deep in Web3. Maybe you're claiming an airdrop you heard about on Discord. Maybe you're minting an NFT before it sells out, or swapping a token while the price is right. You're moving fast, because that's how crypto works — the window is always closing. You click a link, the site looks exactly like the one you know, your wallet pops up asking for a signature, and you approve it without really reading it. And just like that, your wallet is empty. This isn't a rare horror story. Wallet drainers stole hundreds of millions of dollars from ordinary people in a single year, and the scams keep getting better. The fake site is a pixel-perfect copy of the real one. The signature request looks routine. The whole thing is engineered so that a smart, careful person approves their own loss in under ten seconds. Trust Line exists to give you those ten seconds back. ═══════════════════════════════════════ WHAT TRUST LINE ACTUALLY DOES ═══════════════════════════════════════ Trust Line is a free browser extension that sits quietly between you and the crypto web. Most of the time you'll forget it's there. It only steps forward when something looks wrong — and when it does, it tells you exactly what and why, in plain language, before you can make a mistake you can't undo. It works on three layers, because real protection isn't one wall — it's several. ■ LAYER ONE — PHISHING SITES BLOCKED BEFORE THEY LOAD The most dangerous fake sites never get the chance to load. Trust Line checks every domain you visit against an up-to-date list of known crypto phishing sites and drainer domains. If you land on a known scam — a fake MetaMask login, a counterfeit Uniswap, a "claim your rewards" clone of OpenSea — the page is stopped before its malicious code can run. But scammers register thousands of new domains every week, so a blocklist alone isn't enough. Trust Line also analyzes domains on your own device, in real time, using heuristics that catch brand-new fakes no list has seen yet. It spots look-alike letters (the kind that turn "metamask" into something that looks identical but isn't), typosquats, brand names hidden inside domains the brand doesn't own, and bait words like "claim," "airdrop," "restore," and "verify" combined with risky top-level domains. All of this happens locally. Your browsing history never leaves your machine. ■ LAYER TWO — SEE EXACTLY WHAT YOU'RE SIGNING This is where most people actually lose their funds — not on the wrong site, but on the wrong signature. Modern wallet drainers don't steal your keys. They trick you into signing a transaction or an approval that quietly hands them permission to move your assets. The wallet's own pop-up often shows a wall of hex that means nothing to a human. So people click "confirm" and hope. Trust Line decodes the request before you sign and translates it into a sentence you can understand. It flags the specific things that empty wallets: • setApprovalForAll — a single signature that grants access to your entire NFT collection, now and in the future. • Unlimited token approvals — permission to spend far more than the transaction in front of you suggests. • Permit and Permit2 signatures — gasless approvals that act like a spend permission but never show up in your transaction history. • Blind eth_sign requests — signing arbitrary data that legitimate sites almost never ask for. • Zero-payment marketplace orders — "sales" where your asset leaves for nothing. When the request is dangerous, Trust Line shows you a clear warning with the risk level and the reason — so "Critical risk: this grants access to your entire NFT collection" replaces a screen full of code. Then you decide. Your keys, your call. Trust Line only advises; it never moves funds and never touches your seed phrase. ■ LAYER THREE — KNOW WHO YOU'RE PAYING Before you send, Trust Line checks the recipient address against known drainer and scam-address lists, and looks at its on-chain history. If you're about to sign assets over to an address that has already robbed other people, you'll see it — before, not after. ═══════════════════════════════════════ WORKS WITH THE WALLETS YOU ALREADY USE ═══════════════════════════════════════ Trust Line doesn't replace your wallet and doesn't ask you to move anything. It works alongside the wallets you already have, adding a layer of checking on top. It supports any wallet that injects a standard Web3 provider — including the most popular browser wallets like MetaMask — across Ethereum and all EVM-compatible networks. Whether you're on Ethereum, an L2, or another EVM chain, Trust Line reads the request your wallet is about to sign and warns you if it's dangerous. ═══════════════════════════════════════ BUILT FOR HOW PEOPLE REALLY USE CRYPTO ═══════════════════════════════════════ Trust Line protects you across the places drainers hunt. DEXs and swaps. Fake copies of popular decentralized exchanges are some of the most cloned sites in crypto, because that's where people connect wallets and sign. Trust Line blocks the fakes and X-rays the swap approvals so you don't hand over more than you meant to. Exchanges. Scammers impersonate major crypto exchanges in fake login pages and phishing emails to steal accounts and funds. Trust Line recognizes look-alike exchange domains and stops the fake page from loading, so a stolen click doesn't become a stolen account. (No exchange will ever ask for your seed phrase — and Trust Line never will either.) NFT marketplaces. Clones of popular NFT marketplaces are classic drainer traps, usually via a signature that grants collection-wide access. Trust Line flags exactly that kind of request. Airdrops and "claim" pages. The single most common lure. Trust Line treats "claim your airdrop" pages with the suspicion they deserve and warns you before you connect. ═══════════════════════════════════════ PRIVACY BY DESIGN ═══════════════════════════════════════ Security software that spies on you isn't security. Trust Line is built the opposite way. • Site checks run locally on your device. • Trust Line never sees, stores, or asks for your private keys or seed phrase. • The signing itself always happens inside your own wallet — Trust Line only reads the request and advises. • A domain is only sent to our servers when a protection rule actually fires — never your full browsing history, and never personal data. • No account. No sign-up. No wallet connection required to install. You install it, and it just starts protecting you. That's it. ═══════════════════════════════════════ HOW TO GET STARTED ═══════════════════════════════════════ 1. Add Trust Line to your browser — one click, completely free. 2. Browse and transact exactly as you normally would. Trust Line stays invisible until something looks wrong. 3. When it steps in, read the plain-language warning and decide. Approve or reject — you're always in control. There's nothing to configure. No account to create. No permissions to your keys. Install it and forget it's there — until the day it saves your wallet. ═══════════════════════════════════════ WHO TRUST LINE IS FOR ═══════════════════════════════════════ If you hold any crypto, use any Web3 wallet, trade on any DEX, collect NFTs, chase airdrops, or interact with DeFi — Trust Line is for you. It's for the first-timer who just set up MetaMask and doesn't yet know what a malicious approval looks like. It's for the experienced degen who signs dozens of transactions a day and knows that all it takes is one bad one. It's for anyone who has ever felt that small flash of doubt while a wallet pop-up waited for a click — and wished something had their back. Wallet drainers count on you being fast, trusting, and alone in that moment. Trust Line makes sure you're not alone. Add Trust Line — free — and stop wallet drainers before you sign. ═══════════════════════════════════════ FREQUENTLY ASKED QUESTIONS ═══════════════════════════════════════ Is Trust Line free? Yes. Trust Line is a free browser extension. Phishing blocking, transaction analysis, and signature warnings all work without any account or payment. Does Trust Line have access to my private keys or seed phrase? 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 inside your own wallet. Which wallets does it work with? Any wallet that injects a standard Web3 provider, including all popular browser-based Web3 wallets, across Ethereum and EVM-compatible 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 and NFTs. Trust Line detects these requests and warns you before you sign. 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 recipient address reputation, and blocks phishing sites at the browser level before your wallet even opens. 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 personal data. Will it slow down my browser? No. Domain checks are lightweight and run on-device. Trust Line stays invisible until something looks wrong. Do I need to connect my wallet to use it? No. There's no account, no sign-up, and no wallet connection required. Install it and it starts protecting you immediately. ═══════════════════════════════════════ Trust Line is an independent security tool.
