STON.fi is now live on United Network.

STON.fi — one of the leading AMM protocols in the TON ecosystem — is now integrated as the swap provider for TON transactions inside the United Network wallet.
This means smoother swaps, better liquidity routing, and easier access to TON assets — all while keeping full self-custody and explicit transaction approval.

Self-custody rarely starts perfect

It usually goes like this:
1️⃣ Everything on the exchange
2️⃣ First wallet download
3️⃣ Seed phrase anxiety
4️⃣ Finally: a hardware card in your pocket

Because assets on an exchange are convenient — but they’re not fully under your control.

That last step changes everything.

The United Network tap-to-sign card keeps your keys offline and makes self-custody simple — whether you’re just starting or already deep in crypto.

Everyone says “always double-check the address.”

But when you’re rushing, confirmations can still become just another screen to tap through.
United Network slows the moment down — so sending crypto stays intentional.

Less rushing. More certainty.

Most people assume crypto wallets are personal by default.
But real life isn’t always solo.

Couples save together. Families manage shared funds. Partners plan long-term.

With United Network, you can activate multiple cards with the same seed phrase — separate devices, one wallet when it matters.
Set it up once. Use it together

Connecting to a dApp shouldn’t mean trusting a browser extension.

With United Network, the connection is simple — and the security model is explicit:
your private keys never leave the card, and nothing gets signed without you.

How to connect:
1️⃣ Open the dApp
2️⃣ Choose WalletConnect
3️⃣ Tap your card to your phone + enter PIN
4️⃣ Approve the connection (session)

From there, every action stays the same:
tap + PIN to sign. No background approvals.

Hardware wallets are powerful – but they’re not magic.
Let’s talk about social hacking and the risks no device can fully eliminate 👇

Truth or myth:
A hardware wallet protects you from all scams.
❌ Myth.
If you voluntarily approve a transaction or share your seed phrase with a fake “support agent”, the funds are gone – no matter how secure the hardware is.

Truth or myth:
Your seed phrase is just a backup you can store digitally.
❌ Myth.
Seed phrases should never be saved as photos, notes, or files.
Anyone who has it owns your wallet.
Offline only.

Truth or myth:
Malware can’t steal funds if you use a hardware wallet.
❌ Myth.
Clipboard attacks can replace the destination address right before you send.
Always verify addresses on the wallet screen – not just on your phone or laptop.

Truth or myth:
Any hardware wallet is safe if it looks legit.
❌ Myth.
Fake or modified devices exist.
Never buy second-hand wallets.
Always order from official sources and inspect devices carefully.

✅The truth:
Security isn’t just hardware – it’s habits.
Stay skeptical. Verify everything. Never rush a transaction.
That’s the mindset behind United Network

There are moments when a hardware wallet stops being “nice to have” and becomes “I wish I had this right now”. 4 real-life situations where a United Network NFC card is a must

1️⃣ Crossing borders with most of your net worth in crypto
No new SIM. No “let me log in”. No local exchange.
Card in your pocket → keys stay offline → funds stay accessible.

2️⃣ Paying from sketchy Wi-Fi (hotel / café / airport)
Your phone can be compromised.
The chip on the card can’t.

3️⃣When your phone is lost, stolen, or wiped - wallet keys lived on that device are lost. With United Network, they never did.

4️⃣ Signing from multiple devices
New laptop. Office PC. Travel phone.
Same card, same keys — no seeds touching any of them.

If even one of these feels familiar, it’s probably time to move to tap-to-sign self-custody 👉 united.network

United Network partners with United Stables.

United Stables is developing $U, a dollar-backed asset designed to unify liquidity across stablecoins and ecosystems.
As part of this collaboration, we’ll support the upcoming whitelist for the $U token and add $U to the assets you can securely hold and use with your NFC hardware wallet card.

A seed phrase is your ultimate "master key" in the decentralized world. It is a series of random words that acts as a human-readable representation of your wallet's private keys, allowing you to recover your assets if you ever lose your device.
As United Network is a fully non-custodial product, your seed phrase is the only way to restore access.

In United Network, there’s one nuance: our seed phrases are not compatible with other wallets – and other wallets’ phrases won’t work here.
It’s by design. The phrase derivation is linked to our card architecture + multi-chain setup, so it’s made specifically for United Network.
Today it’s 12 words (words may be introduced later).

Same rule either way: United Network only
