Wallet Setup

Everything on Trustfy starts with a Web3 wallet. It's the app that holds your USDT and BNB, and it's what you use to prove “this is really me” when you trade — no username or password required.

What a wallet actually does#

Think of a wallet as a hybrid of a banking app and a signature pad. It shows your balances, and every time an action needs your approval — connecting to Trustfy, funding a trade, releasing funds — your wallet pops up and asks you to approve or reject it. Nothing happens without that approval.

Unlike a bank account, nobody — not Trustfy, not your wallet provider — can freeze it, reverse a transaction, or access it without your permission. That freedom comes with a tradeoff: if you lose access to your wallet, nobody can recover it for you either. That's why the next section matters.

Your seed phrase: the one thing to protect#

Your private key works the same way — it's just a different form of the same secret. Same rule applies: never share it, ever.

• Storing your seed phrase in a photo, note app, or cloud drive — all of these can be hacked or synced somewhere you don't control.
• Typing your seed phrase into any website, including one that looks like Trustfy — Trustfy's real wallet connection never asks for it.
• Sharing a screenshot of your seed phrase in a support chat, even with someone claiming to be Trustfy staff.

BNB Smart Chain, USDT, and BNB#

Trustfy runs on a single blockchain: BNB Smart Chain (BSC). Every wallet, every transaction, and every fee on Trustfy happens there — no other network works.

• USDT (BEP20) is the asset you actually trade — a stablecoin designed to track $1 USD, issued in the BSC-native BEP20 format.
• BNB is BSC's native currency, used only to pay small network fees (see the Gas guide) — it's not what you're trading.

Choosing a wallet#

Trustfy supports several wallets, all of which work with BNB Smart Chain out of the box:

Installing a wallet#

Using Trust Wallet on mobile as the example — the other wallets follow the same shape:

1. 1

   Download the official app

   Get it from the App Store or Google Play — search “Trust Wallet” and confirm the publisher before installing. Never install a wallet from a link sent to you in chat.

2. 2

   Create a new wallet

   Choose “Create a new wallet,” not “I already have a wallet,” the first time.

3. 3

   Write down your seed phrase

   You'll be shown 12 words. Write them on paper, in order, and store them somewhere private. Do not screenshot them.

4. 4

   Confirm your seed phrase

   The app will ask you to re-enter the words to prove you saved them correctly.

5. 5

   Get a little BNB

   Use the wallet's built-in “Buy” option, or send BNB in from an exchange you already use — the equivalent of a few dollars is enough to start.

Connecting your wallet to Trustfy#

1. 1

   Click Start Trading / Connect Wallet

   On the Trustfy homepage or app, click the wallet button in the top-right corner.

2. 2

   Pick your wallet

   Choose MetaMask, Rabby, Trust Wallet, or WalletConnect (for everything else). If you're on mobile with Trust Wallet installed, it opens directly inside the app.

3. 3

   Approve the connection

   Your wallet opens and asks whether to share your wallet address with Trustfy — this is just an address, not access to your funds. Approve it.

4. 4

   Sign a message to verify it's you

   This is called Sign-In With Ethereum. Your wallet will show a short, human-readable message and ask you to sign it. Signing this message is free (no gas) and does not move any funds — it's the equivalent of typing in a password, except nobody can steal it because it's different every time.

5. 5

   You're in

   Your dashboard loads, showing your wallet address in the header. You're now connected and ready to browse or trade.

If your wallet is on the wrong network#

Disconnecting or switching wallets#

Click your address in the header to open the account menu, where you can disconnect or switch to a different wallet at any time. Disconnecting doesn't cancel any open trades or ads — those live on the blockchain and reappear as soon as you reconnect the same wallet.
