This is the weekly cost edition: what it cost to move USDT this week, what it should have cost, and where the arithmetic moved. Fees did not move for a fourth consecutive week — re-verified against all eleven official fee pages on September 14 — and energy held its long low band. The interesting part of this week is a measurement, not a change: an on-chain audit of real transfer energy that lands within ~1% of the model we publish every week.

⚡Energy: 26 SUN to Rent, 100 SUN to Burn — and a Measurement That Agrees
The burn price for energy remains 100 SUN (Proposal #104, effective August 29, 2025). A standard USDT transfer — ~65,000 energy to an address that already holds USDT — burns about 6.5 TRX ≈ $2.20 at this week's verified TRX reference of ~$0.338. An on-chain measurement published this month put the real figure at 64,285 energy — the USDT contract carries TRON's maximum dynamic-energy surcharge — which lands within ~1% of our model. The first transfer to a fresh address costs roughly double (~130,285 energy ≈ $4.40).
Rented energy held its long band: 26 SUN at the best surveyed venue (Tronsell), with the market spanning 26–30 SUN. The same transfer at 26 SUN costs about 1.69 TRX ≈ $0.57 — ~74% cheaper than burning. TRON held ~3-second blocks with no congestion all week.
Takeaway: the burn model survived contact with a real measurement this week — budget with confidence, and activate receiving addresses to avoid the 2× first-transfer surcharge.
📆The Annual Picture
Exchange side: withdrawing from Kraken instead of a $1-floor venue costs 1.5 USDT extra per withdrawal — $78/year at one withdrawal per week, ~$550/year at daily withdrawals. Pay it only when the funds start as fiat on Kraken; otherwise the floor venues win.
Network side: renting energy instead of burning saves 4.8 TRX per transfer — about $84/year at one withdrawal-plus-transfer per week (4.8 × $0.338 × 52). The saving scales linearly with volume, which is why batch services and payroll payers feel it first.
Combined: the worst reasonable path (Kraken + ERC20 + burn) versus the best (floor venue + TRC20 + rent) differs by roughly $3.12 per cycle — the same number, week four running, because none of the inputs moved.
🔀What Changed / What Did Not
- Changed: nothing in fees (fourth consecutive zero-change week) or energy prices (26–30 SUN band intact).
- Changed: TRX drifted up ~1% on the week (to $0.3383 close on Sep 13), nudging the no-energy burn cost by a couple of cents.
- Confirmed: a real on-chain measurement (64,285 energy per standard transfer) validates the 65,000 model to within ~1% — and flags the fresh-address 2× surcharge worth ~$2.20 extra per first transfer.
- Confirmed: Trust Wallet now offers Tronify energy rental on a default path — more rental demand should keep competitive pressure on rental prices.
- Watch: if TRON's dynamic-energy surcharge on the USDT contract (currently at its maximum) ever eases, the no-energy burn could halve — rental savings would compress proportionally.
Fourth week, same answer: OKX + TRC20 (or any floor venue) with rented energy — ~$1.57 all-in per $1,000. The optimal path is unchanged five weeks running, and this week even the model itself got independently confirmed.
