I've been trading and providing liquidity on TON for a while now, and if you'd asked me a year ago what STON.fi was, I'd have said "the biggest DEX on TON." That's still true. But watching how the protocol has moved over the past year, I don't think "DEX" is the right word for it anymore. It's turning into liquidity infrastructure that other things get built on top of — and the numbers back that up.
Let's start with where things actually stand, not where the marketing says they stand.
As of recent data pulled from DEXTools and DefiLlama, TON's total DeFi TVL sits around $81.5 million, with STON.fi alone accounting for roughly $38.2 million of that — meaning close to half of everything locked on TON runs through this one protocol. Daily DEX volume through STON.fi has been running around $37.4 million, out of total TON chain volume that isn't much bigger than that.
I want to sit on that stat for a second: STON.fi doesn't just have the biggest slice of TON DeFi — depending on the week, it's reportedly capturing somewhere between 80% and 90% of all DEX activity on the chain, according to comments from STON.fi's own team reported by BeInCrypto. That's not a market leader. That's closer to a monopoly on liquidity for an entire L1.
"When one protocol handles nine out of every ten swaps on a chain, it stops being 'the biggest DEX' and starts being 'the thing the chain runs on.' That's the lens I use to look at STON.fi now."
Zoom out further and the trajectory gets more interesting. At one point last year, STON.fi's team disclosed that the protocol had crossed over $5 billion in cumulative trading volume, with peak TVL near $400 million — all of that on TON alone, before any cross-chain volume was even part of the picture (Metaverse Post). Their own stated target at the time was $10 billion in all-time volume just from TON-native activity. I don't take roadmap targets at face value, but I do think it's worth noting they've already blown past several of their own earlier milestones.
The part of this I actually find technically interesting is Omniston, STON.fi's aggregation and routing layer. Originally, its job was simple: connect every AMM pool on TON and find the best price. But according to STON.fi's own team, that model hit a ceiling — if nobody bothered to provide liquidity for a specific pair, no amount of smart routing fixes a hole that isn't there.
Their answer was escrow swaps: a parallel execution path that taps into private liquidity from professional market makers ("resolvers") instead of relying only on public AMM pools. Omniston now checks both public and private liquidity sources and routes each swap through whichever gives the better outcome (BeInCrypto).
"This is the detail that convinced me Omniston isn't a marketing layer bolted onto a DEX. It's an actual execution engine making a decision every time you swap — public pool or private resolver, whichever wins."
Here's where it stops being a TON story and starts being a broader DeFi story.
STON.fi's public roadmap, documented at docs.ston.fi and ston.fi, shows a clear progression:
I want to be precise about why HTLC (Hash Time-Locked Contracts) matters here instead of a traditional bridge: it's a self-custodial swap mechanism with a built-in refund path if a counterparty doesn't complete their side in time. You're not handing your assets to a bridge contract and hoping it doesn't get exploited — the swap either completes atomically or reverts. Given how many nine-figure bridge hacks we've all watched happen over the past few years, I think this design choice is the single most underrated part of STON.fi's roadmap.
"I've lost count of how many bridges I've stopped using after a hack. An atomic-swap design with a refund path isn't flashy, but it's the kind of boring engineering decision that actually keeps my funds safe."
If STON.fi executes on this the way the roadmap suggests, a few things become possible that aren't really possible today on TON:
That said, I'd flag the obvious counterpoint myself: expanding to more chains resets a lot of the competitive dynamics that let STON.fi dominate TON. Cross-chain liquidity is a much more crowded, much harder fight than TON-native swaps, and 80-90% market share on one chain doesn't automatically translate anywhere else.
I don't think STON.fi is "just a DEX with a roadmap slide." The market share numbers, the volume history, and the actual engineering choices behind Omniston's escrow swaps and HTLC design all point toward a team building infrastructure first and a product interface second. Whether the cross-chain expansion captures anywhere near the share it has on TON is the real open question — and it's the one I'll be watching closest over the next few quarters.
