STON.fi Raises $9.5M Series A from Ribbit + CoinFund: What It Means

June 3, 2026 — STON.fi Dev officially announced a Series A round at $9.5 million from Ribbit Capital and CoinFund. It’s the first top-tier VC funding for a TON DeFi project and one of the largest rounds in the TON ecosystem ever.

This piece covers what it means for STON.fi, how the DeDust rivalry shifts, and where the team commits to spend the money over the next year.

2026 context: the news arrives 3 days after the Toncoin → Gram rebrand (June 1) — TON DeFi sits in a massive attention spotlight. Full rebrand context in the main explainer.

TL;DR

Who Ribbit Capital and CoinFund are

Ribbit Capital — top-tier fintech VC

Ribbit Capital is one of the world’s most influential fintech investors. Portfolio highlights:

• Robinhood (IPO 2021, peak $32B valuation)
• Coinbase (IPO 2021, peak $86B)
• Nubank (Brazilian neobank, IPO 2021)
• Revolut (UK neobank, $33B valuation 2024)
• Wealthfront, Affirm, Credit Karma

When Ribbit invests in a crypto project, it’s a serious institutional-readiness signal. Their crypto stakes include Coinbase, BlockFi (pre-bankruptcy), Mercury (banking for crypto startups).

CoinFund — institutional crypto asset manager

CoinFund focuses on early-stage Web3 protocols. Portfolio:

• Solana (early backer)
• Polygon (early)
• Filecoin
• Helium
• The Graph

CoinFund is a specialized crypto VC, unlike Ribbit (generalist fintech). Their participation is strategic alignment with TON as a platform.

Why STON.fi specifically

STON.fi — the largest DEX project by pair diversity

In TON’s 2026 DEX landscape:

STON.fi has more trading pairs, V2 fee structure (with configurable LP rewards), and more mature SDK. DeDust is bigger by deposits, but STON.fi has a more active developer ecosystem and brand recognition.

TradingView integration (new)

In May 2026, STON.fi (and DeDust) integrated into TradingView — now 90M+ traders can view TON DEX data directly in their usual charting tools. Massive distribution boost.

Tonation feature

STON.fi was first in the TON ecosystem to launch Tonation — a live-stream donation feature where viewers tip streamers through swap mechanics. A textbook product-led growth play — expanding DEX use cases beyond pure trading.

Where the $9.5M goes

Per the team + insider info:

1. STON.fi V3 — concentrated liquidity (mid-2026)

Uniswap-V3-style on TON. Features:

• LPs specify price range for positions
• Capital efficiency grows 10-100× for popular pairs
• Direct competition with TONCO (TON’s current single CLMM DEX)

This is the main roadmap item Series A funds. If V3 succeeds, STON.fi can close the TVL gap to DeDust in 6-12 months.

2. Cross-chain bridges

STON.fi roadmap for 2026:

• TON ↔ TRON bridge (H2 2026) — opens TON to the $50B+ TRC-20 USDT ecosystem
• TON ↔ Ethereum via partnerships with existing bridges (Symbiosis, Allbridge)
• TON ↔ Solana — speculative, unconfirmed

3. Team

From 15 people in 2025 → 40+ by end of 2026. Heavy engineering + BD growth.

4. Marketing + audits

V3 contract audit is critical pre-launch. Marketing via crypto-Twitter, conferences, partnerships with TON Foundation.

5. Tonation expansion

Expanding Tonation to more streaming platforms (Twitch, TikTok Live), integration with Telegram Mini Apps.

What changes for STON token and stakers

STON token — STON.fi’s governance token. In 2026, holders can:

• Vote on protocol parameters
• Earn LP rewards (boosted)
• Stake STON for extra pool fees

After Series A news, STON token likely received a 20-50% pump (typical reaction to funding announcements). Long-term — funding on its own doesn’t move price. Execution and actual usage do.

What to watch:

• V3 launch (if on time mid-2026 → bullish for STON)
• TON-TRON bridge (if on time H2 2026 → bullish)
• TVL gap vs DeDust (if STON.fi overtakes DeDust in 12 months → strong signal)

What this means for the STON.fi vs DeDust race

DeDust response — unclear so far

DeDust has no announced large fund round as of the news date. That’s a competitive disadvantage. If STON.fi ships V3 on time, DeDust will be catching up.

That said, DeDust has:

• TVL lead ($379M vs $145M)
• Older user base (since 2022)
• Native TON Foundation integration

Likely scenario: DeDust launches its own funding round within 6 months in response.

TONCO — niche, not direct competition

TONCO ($35M TVL) is already a single CLMM-DEX. When STON.fi V3 launches with CLMM, TONCO will be in direct competition for CLMM LPs.

What it means for the broader TON ecosystem

4 effects:

1. Validation — Ribbit Capital investing in TON DeFi = institutional money confirms the thesis “TON is mainstream-ready”
2. Multiplier — other VCs will now look at TON DeFi projects (Storm Trade, EVAA, Tonstakers can ride swing momentum)
3. Developer talent attraction — STON.fi can now pay competitive salaries (TON DeFi developer in 2026 = $150K-300K base + tokens)
4. MTONGA stride — indirectly supports Durov’s program (though Series A is a STON.fi deal, not Telegram’s)

Gram price scenario after funding news

Base assumption: Series A news adds 3-7% to Gram price over 24-72h as a bullish ecosystem signal. Plus direct effect on STON token (20-50% pump).

But most of the effect lands on the STON token. Gram price follows the broader TON ecosystem trend, not a single funding deal.
