DeFi lost over $2.8 billion to hacks and compromised wallets in 2024. the shocking part isn\u2019t the number. it\u2019s that most of those losses came from hot wallets: browser extensions, phone apps, anything connected to the internet around the\u00a0clock<\/p>\n
you trade on a DEX to skip custodial risk. then you store your keys in a browser extension. strange place to draw the\u00a0line<\/p>\n
hardware wallets solved this for bitcoin holders a decade ago. sign offline, key never touches the internet, phishing site gets nothing\u00a0useful<\/p>\n
defi traders mostly skipped that lesson. hardware wallets felt too clunky for active trading. plug in a device, navigate firmware menus, confirm on a tiny screen. fine for long-term storage. painful for swapping tokens twice a\u00a0week<\/p>\n
so traders kept keys hot and hoped for the\u00a0best.<\/p>\n
arculus approached this differently. the wallet lives on a metal card with an embedded secure element chip. no USB, no bluetooth, no persistent connection. you authenticate with a PIN and tap the card to your phone via NFC. three factors: something you have (the card), something you know (the PIN), something you are (card must physically touch your\u00a0device)<\/p>\n
that third factor is the one that matters for trading. a remote attacker who steals your seed phrase still can\u2019t sign a transaction without the physical card in\u00a0hand<\/p>\n
TON\u2019s defi ecosystem grew fast through 2024 and 2025. STON.fi<\/a> handles hundreds of millions in monthly volume. the network\u2019s throughput and fee structure are competitive with any L2 out\u00a0there<\/p>\n the bottleneck wasn\u2019t liquidity. users who cared about security couldn\u2019t connect hardware wallets to TON-based dapps. the tooling wasn\u2019t\u00a0there<\/p>\n WalletConnect fixed that<\/a>. the protocol, already proven on EVM chains, extended support to TON. arculus added WalletConnect integration. two things that existed separately plugged together, and suddenly you could connect a metal card in your pocket to a TON DEX without sacrificing either security or usability<\/p>\n open STON.fi<\/a> on browser or\u00a0phonechoose WalletConnect instead of a hot\u00a0walletscan the QR code with the arculus\u00a0appyour phone pairs with the dapp\u00a0session<\/p>\n when you confirm a swap, STON.fi sends an unsigned transaction to arculus. you tap the card to the back of your phone. the secure element signs it offline. signed transaction goes to the\u00a0network.<\/p>\n your private key moved through zero internet-connected systems. the browser saw a session handshake and a signed transaction, nothing\u00a0else.<\/p>\n the STON.fi guide<\/a> walks through the full pairing steps if you want to read it before your first session. worth 5\u00a0minutes.<\/p>\n TON has a large base of users who came in through telegram, explored crypto through TON-native apps, and now sit on real balances they want to put to work. a lot of them haven\u2019t touched defi because the security model felt\u00a0opaque.<\/p>\n hardware wallet support via WalletConnect lowers that entry point. the security model becomes physical and visible: card in pocket, tap to sign. users who were uneasy about browser extensions now have an option that maps to how they already think about security.<\/p>\n omniston<\/a>, STON.fi\u2019s aggregation protocol, pulls liquidity across TON. more users entering with better security habits means deeper liquidity and fewer protocol-level meltdowns when individual wallets get\u00a0drained.<\/p>\n updates on integrations like this land in the STON.fi telegram channel<\/a> as they roll\u00a0out.<\/p>\n arculus cards are $99. if the price was making you hesitate, the code TON20<\/strong> knocks $20 off. just useful to\u00a0know<\/p>\n the real cost is the mental model shift: from \u201cmy wallet is an app\u201d to \u201cmy wallet is an object.\u201d that one\u2019s free, and it\u2019s the shift that actually changes your risk\u00a0profile<\/p>\n Disclaimer: This article is for informational purposes only and does not constitute financial advice.
