DeFi on TON After the Rebrand: STON.fi, DeDust, Storm Trade

The Toncoin → Gram rebrand touches every DEX, lending protocol, and derivatives venue on TON. Good news for users: technically nothing breaks. Bad news for developers: you need to audit bots, indexers, and integrations that may hardcode the TON string.

This piece is the systematic breakdown of what changes (and what doesn’t) for each major DeFi protocol in the TON ecosystem.

TVL map and the biggest protocols

Total TON DeFi TVL: ~$760M → ~$835M (~10% rise from rebrand price impact).

STON.fi: what changes

What does NOT change

• All pools — keep functioning. Pool jettonMaster addresses remain the same.
• LP tokens — unchanged. If you held a TON/USDT LP token, in 3 weeks it’s a GRAM/USDT LP token (same token).
• Liquidity — stays in the pools; nothing to pull.
• Referral programs — referral_address keeps working (we use UQBXcHsMJ1TpBtMvuLKFDrGkmmsPdwFm80oIvBWbgVqRqBb6 via cloak).
• V2 fee structure — unchanged (0.3% standard pools, custom for V2 pools).

What changes

• UI labels — every “TON” mention in pool cards and the swap UI moves to “GRAM”. Transition over 1–2 weeks.
• pTON jetton (wrapped native) — display name “pTON” may switch to “pGRAM”, but the pTON jettonMaster address does not change. Critical for indexers and bots.
• Search and filter — you’ll search for pools by “GRAM” instead of “TON” after the UI migration.

User action

• Just keep trading. No migrations.
• For large swaps, wait 2–3 days after exchange UI swaps to avoid confusion with jetton Gram (see our confusion-buster).

DeDust: what changes

DeDust is the second-largest DEX by TVL on TON. Architecturally similar to STON.fi (AMM) with its own smart contract framework.

What does NOT change

• Pools and LP tokens — same as STON.fi
• Trading fees — unchanged
• Smart contract addresses — all pools and factories on the same addresses

What changes

• UI — GRAM ticker transition over 1–2 weeks
• Native wrapping — DeDust uses its own native-TON wrapper, which will also be renamed

swap.coffee: aggregator effect

swap.coffee is a DEX aggregator (routes a swap via STON.fi/DeDust/TONCO for best execution). The rebrand doesn’t affect functionality — the aggregator works at the smart-contract level, not the ticker level.

The only visible change: UI shows “GRAM” instead of “TON”.

Storm Trade: perpetuals impact

Storm Trade is the largest perpetuals venue on TON. Post-rebrand:

What does NOT change

• Open positions — keep running; PnL is calculated correctly
• Cross-margin — TON collateral remains collateral (now GRAM)
• Leverage — unchanged
• Funding rate — formula unchanged
• Liquidation threshold — same values

What changes

• Pair display — “TON-USD” → “GRAM-USD”. A pure label change.
• Base margin coin — remains the same (native GRAM, ex-TON)

Trader action

• No action. Positions stay.
• If your order uses hardcoded “TONUSD” in an API — update to “GRAMUSD” within 2–3 weeks.

Lending: EVAA and DAOlama

EVAA — money-market lending

EVAA is a compound-style lending protocol. Post-rebrand:

• TON deposits — remain (now GRAM)
• TON debts — remain (now GRAM debts)
• Interest rate — unchanged
• Collateral ratio — unchanged
• Liquidation threshold — unchanged

Critically: liquidation bots need to update tickers in monitoring scripts.

DAOlama — NFT-collateralized lending

DAOlama issues TON loans against NFT collateral. Post-rebrand:

• Loans denominated in GRAM instead of TON (same asset)
• LTV parameters unchanged
• Liquidation logic unchanged

Liquid staking: tsTON, bemoTON, hTON

The largest TON DeFi TVL segment. Post-rebrand:

tsTON (Tonstakers)

• tsTON — may be renamed to tsGRAM (or kept as tsTON for backward compatibility). Tonstakers hasn’t announced yet.
• Conversion rate tsTON ↔ TON remains (now tsTON ↔ GRAM)
• APR — unchanged (~3.5%)

bemoTON (bemo)

• Bemo — community vote on renaming. May keep bemoTON to minimize disruption.
• Reward emission — unchanged

hTON (Hipo)

• Hipo — the youngest, most likely to switch to hGRAM
• TVL keeps growing (Hipo showed the fastest growth in April–May 2026)

Critical: derivative tokens do NOT change

tsTON, bemoTON, hTON, stTON are jettons on top of TON network, not the native coin. Their jettonMaster addresses don’t change. So technically your tsTON stays tsTON, even if the UI shows tsGRAM.

What changes for developers

If your code uses ticker strings

// Pre-rebrand
if (token.ticker === 'TON') { ... }

// Within 2–3 weeks after rebrand
if (token.ticker === 'TON' || token.ticker === 'GRAM') { ... }

This is the hardcoding pattern to update. Best practice — use contract address or null (for native), not strings.

If your code uses jettonMaster addresses

No changes. JettonMaster addresses of pools, derivative tokens, all jettons — unchanged.

If you do oracle integration

Pyth, RedStone, and other oracles may rename the feed from “TON/USD” → “GRAM/USD”. Verify subscribe names during the transition window.

If you embed charts (Dexscreener, GeckoTerminal)

Embed URLs may change slightly. Verify after 2–3 weeks.

What protocols are saying (June 1, 2026)

STON.fi

“We’re updating UI labels over the next 7–10 days. All pools, contracts, LP tokens stay exactly as is. No action needed from LPs or traders.”

DeDust

“Rebrand has zero impact on smart contracts or liquidity. UI update rolling out this week.”

Storm Trade

“Open positions safe. Display ticker updating to GRAM-USD over the next 14 days.”

EVAA

“Lending protocol works as designed. Display naming aligned with Tonkeeper / MyTonWallet schedule.”

Risks for DeFi users

Despite the technically clean rebrand, several risks during the transition:

1. Confusion attacks

Same as native vs jetton Gram (see our confusion-buster), DeFi may see new scam pools with names like “GRAM/USDT (new)” actually using the jetton Gram instead of native. Always verify the jettonMaster address of the pair.

2. Bot/aggregator confusion

In the first days, aggregators may surface invalid routes due to ticker-mapping desync. Don’t do large swaps in the first 48–72 hours — wait for things to settle.

3. Hardcoded scripts

If your arbitrage bot or yield-farming script hardcodes the ‘TON’ string — it may break in 2–3 weeks when DEXes finalize the GRAM transition. Audit and update before then.

4. Oracle staleness

In the first 24–48 hours after the announcement, some oracles may show stale prices due to the rename process. Lending positions with thin collateral ratio have elevated false-liquidation risk. If you’re leveraged near liquidation, top up or close ahead.

Action checklist by user group

LPs on STON.fi/DeDust/TONCO

• No action needed
• Within 2–3 weeks check the UI — should show GRAM instead of TON
• Referral programs keep working

Traders on Storm Trade

• Open positions safe
• Update API tickers within 2–3 weeks if using hardcodes

Lenders in EVAA / DAOlama

• Deposits and debts persist
• If your position is near liquidation, top up collateral in the first 48 hours

Stakers in Tonstakers / bemo / Hipo

• No action
• tsTON/bemoTON/hTON keep the same contracts
• APR unchanged

Developers and DeFi infrastructure

• Audit scripts for hardcoded ‘TON’ strings
• Update ticker mapping
• Use jettonMaster addresses instead of strings for long-term robustness
• Update Pyth/RedStone feed names if needed

Long-term effect on DeFi TVL

A rebrand by itself doesn’t move TVL long-term. But possible MTONGA step 5 (Gram integration into Telegram products) can. If Telegram actually uses Gram for ads, Stars, Premium — that brings millions of new TON wallets into the ecosystem. DeFi TVL could double or triple in 12 months if integration is real.

See our MTONGA step 5–7 forecast for the reasoning.
