A few weeks ago i was in a telegram group and someone dropped a link that said “STONfi airdrop’’, ‘’connect wallet to claim.” It looked right. Same colors, same logo, even a URL that read fine at a glance. I had my wallet open and my thumb literally over the connect button before something made me stop and actually check the domain character by character. It wasn’t the real site. After checking thoroughly, I discovered that one letter was swapped.
Nothing happened to me that day, because I double-checked and was very careful. But the bitter truth is that somebody else, somewhere, didn’t.
I’m bringing this up because of what happened on August 23rd, It’s completely unrelated to TON, but worth understanding anyway. A lending protocol called Term Finance lost $8.5 million, and the way it happened should change how you think about “SAFETY” in DeFi. It wasn’t a bug.
Security firms who looked into it were clear about that. An attacker acquired enough governance voting power to simply instruct the protocol’s vaults to release funds and the vaults did exactly what they were programmed to do when governance tells them something. There was a seven-day delay built in as a safeguard, and liquidity providers technically had the power to veto it. But neither of these things stopped the exploit in time.
What I'm basically trying to say is that the code worked perfectly and as a result, it makes the incident very unsettling. For years, the DeFi safety pitch has basically been “audited contracts, no vulnerabilities, trust the math.” Term Finance is a reminder that the math was never the whole security model. There’s a permission layer sitting on top of the code governance votes, admin keys, multisig approvals and if someone captures that layer, an audit doesn’t save you. It’s not a coincidence that this keeps happening as either compromised access and permissions have overtaken plain contract bugs as the leading cause of DeFi losses this year, by incident count.
TON doesn’t really have a “governance vote gets hijacked” problem the way a lending protocol does, but it has its own version of the same underlying issue, the permission layer around your wallet, not around the protocol. TON’s biggest strength is that DeFi lives right inside Telegram through Mini Apps. That’s also exactly why fake STONfi and DeDust look-alikes keep showing up because a convincing clone inside a chat you already trust is a much easier trap than a convincing clone on the open web. Security researchers have been documenting this pattern for a while now, fake mini-apps, phishing bots posing as “wallet support,” and TonConnect prompts asking for approval scopes way broader than they need. The wallet connection itself is the exploit. Not a bug in STONfi’s code, a fake version of the button that connects to it.
If you’re using STONfi or any TON DEX regularly, a few things I’ve started doing without ever thinking twice about them anymore are these ones ill be sharing now.
[1]I only open links from a bookmarked link or the official Telegram channel, never from a link someone dropped in a group chat, no matter how urgent it looks which is the very first line of defense i always consider.
[2]I read what a TonConnect prompt is actually asking for, “connect” is fine, “approve unlimited” is not, and if a permission request feels broader than what the action requires, I back out and deny access immediately.
[3]
And i also often go into my wallet and clean out old app connections I don’t recognize or don’t use anymore, because a stale, forgotten approval is exactly the kind of thing that sits there quietly until someone finds a way to use it to drain your wallet.
On the protocol side, STONfi does some of the things you’d want a real DEX to do or consider in terms of their security, like regular third-party audits, a public bug bounty program, non-custodial architecture so the platform itself never holds your keys, and ongoing on-chain monitoring for unusual activity. That matters, and it’s more than a lot compared to what some of these newer protocols bother doing. But Term Finance is proof that even a protocol doing everything right on the code side can still get hit somewhere else. STONfi being audited protects you from a bad contract. It doesn’t protect you from clicking the wrong link in a telegram chat at any point in time.
The uncomfortable truth of DeFi security in 2026 is that the weakest point usually isn’t the smart contract anymore. It’s whoever’s holding the keys, a governance vote, an admin wallet, or, most often for regular users, you, that is paying half attention to a ‘’CONNECT’’ button that looks very real.
So, to finish up the read, ill leave you with a direct source of support link to always verify any STONfi related product you come across at any point in time you might have doubts about what you see.
