Get live network parameters -const params = await tronWeb.trx.getChainParameters() -const energyPrice = params.find(p => p.key === 'getEnergyFee')?.value ?? 100 -const bandwidthPrice = params.find(p => p.key === 'getTransactionFee')?.value ?? 1000 - -// 2. Estimate energy using actual sender and recipient -const result = await tronWeb.transactionBuilder.triggerConstantContract( - contractAddress, - 'transfer(address,uint256)', - {}, - [ - { type: 'address', value: recipient }, - { type: 'uint256', value: amount } - ], - sender // CRITICAL: Must use real sender! -) - -const energyUsed = result.energy_used // ~64k or ~130k - -// 3. Apply safety margin for dynamic energy spikes -const energyFee = energyUsed * energyPrice * 1.5 // 1.5x margin - -// 4. Calculate bandwidth -const bandwidthFee = 276 * bandwidthPrice // TRC20 typical size - -// 5. Add memo fee if present -const memoFee = hasMemo ? 1_000_000 : 0 - -// Total -const totalFee = energyFee + bandwidthFee + memoFee -``` - -#### For TRX Transfers: - -```typescript -// 1. Build actual transaction to measure size -let tx = await tronWeb.transactionBuilder.sendTrx(recipient, amount, sender) - -// 2. Add memo if present -if (memo) { - tx = await tronWeb.transactionBuilder.addUpdateData(tx, memo, 'utf8') -} - -// 3. Calculate bandwidth from actual size -const bytes = (tx.raw_data_hex.length / 2) + 65 // +65 for signature -const bandwidthFee = bytes * bandwidthPrice - -// 4. Add memo fee -const memoFee = memo ? 1_000_000 : 0 - -// Total -const totalFee = bandwidthFee + memoFee -``` - -### Why We Use 1.5x Safety Margin - -Dynamic energy can spike up to 3.4x during congestion. We use 1.5x as a balance: -- **Covers most congestion** (light to medium spikes) -- **Not excessively high** (better UX than 3.4x worst-case) -- **Validated**: Results in 1.4x conservative estimates on average - -**Real data**: -- Actual costs: 6.8-7.9 TRX -- Our estimates: 9.9-10.9 TRX -- Ratio: 1.39-1.46x (conservative but reasonable) - ---- - -## Cost Breakdown by Transaction Type - -| Transaction Type | Energy | Bandwidth | Memo | Total | USD | -|-----------------|--------|-----------|------|-------|-----| -| TRX transfer (no memo) | 0 | 0.198 TRX | 0 | **0.198 TRX** | **$0.04** | -| TRX transfer (with memo) | 0 | 0.231 TRX | 1 TRX | **1.231 TRX** | **$0.25** | -| TRC20 (existing balance) | 9.64 TRX | 0.276 TRX | 0 | **9.92 TRX** | **$1.98** | -| TRC20 (new address) | 19.5 TRX | 0.276 TRX | 0 | **19.78 TRX** | **$3.96** | -| TRC20 with memo (existing) | 9.64 TRX | 0.276 TRX | 1 TRX | **10.92 TRX** | **$2.18** | -| TRC20 with memo (new) | 19.5 TRX | 0.276 TRX | 1 TRX | **20.78 TRX** | **$4.16** | - -*Estimates include 1.5x safety margin on energy* - ---- - -## Reducing Fees - -### Option 1: Stake TRX for Energy -- Stake ~1,000 TRX to get free energy -- Reduces TRC20 fees to just bandwidth (~$0.07) -- Good for frequent senders -- TRX remains yours (just frozen) - -### Option 2: Rent Energy -Services like NETTS, TronNRG: -- Rent 65,000 energy for ~2.85 TRX -- Total: 2.85 + 0.35 = 3.2 TRX (~$0.64) -- **53% cheaper** than burning TRX -- Good for occasional senders - -### Option 3: Use Different Networks -Trade-offs to consider: -- **BSC**: Cheaper ($0.10-0.50) but centralized -- **Polygon**: Cheapest ($0.01-0.10) but different security model -- **TRON**: Mid-range ($1-3) with good decentralization - ---- - -## Common Questions - -### Q: Why did the old implementation show $0.05 fees? - -**A**: Bug! It returned a fixed 0.268 TRX for ALL transactions, completely ignoring energy costs. - -### Q: Are $1-2 USDT fees normal on TRON? - -**A**: Yes, absolutely normal. This is validated by: -- Official TRON documentation -- NETTS energy rental service pricing -- Real on-chain transactions -- Other wallet implementations - -### Q: Why does USDT cost more than other TRC20s? - -**A**: USDT is the most popular TRC20 token. TRON's dynamic energy model applies higher costs to popular contracts to prevent spam and maintain network quality. - -### Q: Why does the estimate vary (9.9 TRX vs 19.5 TRX)? - -**A**: Depends on recipient's current USDT balance: -- **Has USDT**: ~64k energy needed β†’ 9.9 TRX estimate -- **No USDT**: ~130k energy needed β†’ 19.5 TRX estimate - -We detect this by using the sender's address in `triggerConstantContract()`, which simulates the transaction accurately. - -### Q: Why is the estimate higher than actual cost? - -**A**: Safety margin! We apply 1.5x multiplier on energy to account for: -- Dynamic energy spikes during congestion (can reach 3.4x) -- Network parameter changes -- Edge cases and race conditions - -Better to overestimate and succeed than underestimate and fail with OUT_OF_ENERGY. - -### Q: What happens if I don't have enough TRX? - -**A**: Transaction fails with **OUT_OF_ENERGY** error. You lose partial fees (3-4 TRX) with no value transferred. This is why accurate fee estimation is critical! - ---- - -## Technical Deep Dive - -### SSTORE Instruction Costs - -TRC20 tokens store balances in a mapping. When you transfer: - -```solidity -// In USDT contract: -balanceOf[sender] -= amount; // Update sender (5k energy if balance > 0) -balanceOf[recipient] += amount; // Update or initialize recipient -``` - -**Recipient has USDT** (balance > 0): -``` -SSTORE with existing value: 5,000 energy -Total transfer cost: ~64,000 energy -``` - -**Recipient has NO USDT** (balance = 0): -``` -SSTORE initializing storage: 20,000 energy -Total transfer cost: ~130,000 energy -``` - -**Difference**: 15,000 energy Γ— 100 SUN = 1.5 TRX - -Combined with all operations: 65,000 energy difference β†’ ~6.5 TRX difference - -### Dynamic Energy Formula - -``` -Final Energy = Base Energy Γ— (1 + energy_factor) - -energy_factor increases when: -- Contract usage > threshold in maintenance cycle -- Increases by increase_factor (20%) per cycle -- Capped at max_factor (3.4x) -``` - -For USDT: -- Normal: 1.0x (64k energy) -- Light congestion: 1.2x (77k energy) -- Medium congestion: 1.5x (96k energy) -- Heavy congestion: 2.0x (128k energy) -- Extreme: 3.4x (218k energy) - -Our 1.5x safety margin covers most congestion scenarios. - -### Why triggerConstantContract? - -TRON provides two methods for energy estimation: - -**1. estimateEnergy** (More accurate) -- Not enabled on TronGrid by default -- Requires `vm.estimateEnergy` and `vm.supportConstant` config -- Returns `energy_required` directly - -**2. triggerConstantContract** (Available everywhere) -- Simulates contract call without broadcasting -- Returns `energy_used` field -- Available on all public nodes - -We use `triggerConstantContract` for **compatibility** - it works on TronGrid and all other providers. - ---- - -## Validation - -### Tested Against Real Transactions - -| Transaction | Type | Energy Used | Actual Fee | Our Estimate | Ratio | -|-------------|------|-------------|------------|--------------|-------| -| 3bc6a364... | USDT send | 64,285 | 6.77 TRX | 9.92 TRX | 1.46x | -| 9E8E5D73... | USDT + memo | 64,285 | 7.84 TRX | 10.92 TRX | 1.39x | -| E8E60EE1... | USDT + memo | 64,285 | 7.82 TRX | 10.92 TRX | 1.40x | -

Previously, the activation check was only in the TRX sell path, causing swaps like USDT β†’ TRX to new addresses to underestimate fees by 1 TRX. Moved activation check outside the sell-type conditional so it applies to all swaps (TRC-20 and native TRX). πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../SunioSwapper/utils/getQuoteOrRate.ts | 52 +++++++++++-------- 1 file changed, 29 insertions(+), 23 deletions(-) diff --git a/packages/swapper/src/swappers/SunioSwapper/utils/getQuoteOrRate.ts b/packages/swapper/src/swappers/SunioSwapper/utils/getQuoteOrRate.ts index 9d8dc3c3ec1..ccd079ddcec 100644 --- a/packages/swapper/src/swappers/SunioSwapper/utils/getQuoteOrRate.ts +++ b/packages/swapper/src/swappers/SunioSwapper/utils/getQuoteOrRate.ts @@ -130,6 +130,26 @@ export async function getQuoteOrRate( const bandwidthPrice = params.find(p => p.key === 'getTransactionFee')?.value ?? 1000 const energyPrice = params.find(p => p.key === 'getEnergyFee')?.value ?? 100 + // Check if recipient needs activation (applies to all swaps) + let accountActivationFee = 0 + try { + const recipientInfoResponse = await fetch( + `${deps.config.VITE_TRON_NODE_URL}/wallet/getaccount`, + { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ address: receiveAddress, visible: true }), + }, + ) + const recipientInfo = await recipientInfoResponse.json() + const recipientExists = recipientInfo && Object.keys(recipientInfo).length > 1 + if (!recipientExists) { + accountActivationFee = 1_000_000 // 1 TRX + } + } catch { + // Ignore activation check errors + } + // For native TRX swaps, Sun.io uses a contract call with value // We need to estimate energy for the swap contract, not just bandwidth if (isSellingNativeTrx) { @@ -142,35 +162,18 @@ export async function getQuoteOrRate( // Estimate bandwidth for contract call (much larger than simple transfer) const bandwidthFee = 1100 * bandwidthPrice // ~1100 bytes for contract call (with safety buffer) - // Check if recipient needs activation - let accountActivationFee = 0 - try { - const recipientInfoResponse = await fetch( - `${deps.config.VITE_TRON_NODE_URL}/wallet/getaccount`, - { - method: 'POST', - headers: { 'Content-Type': 'application/json' }, - body: JSON.stringify({ address: receiveAddress, visible: true }), - }, - ) - const recipientInfo = await recipientInfoResponse.json() - const recipientExists = recipientInfo && Object.keys(recipientInfo).length > 1 - if (!recipientExists) { - accountActivationFee = 1_000_000 // 1 TRX - } - } catch { - // Ignore activation check errors - } - networkFeeCryptoBaseUnit = bn(energyFee) .plus(bandwidthFee) .plus(accountActivationFee) .toFixed(0) } catch (estimationError) { - // Fallback estimate: ~2k energy + ~1100 bytes bandwidth + // Fallback estimate: ~2k energy + ~1100 bytes bandwidth + activation fee const fallbackEnergyFee = 2000 * energyPrice const fallbackBandwidthFee = 1100 * bandwidthPrice - networkFeeCryptoBaseUnit = bn(fallbackEnergyFee).plus(fallbackBandwidthFee).toFixed(0) + networkFeeCryptoBaseUnit = bn(fallbackEnergyFee) + .plus(fallbackBandwidthFee) + .plus(accountActivationFee) + .toFixed(0) } } else { // For TRC-20 swaps through Sun.io router @@ -179,7 +182,10 @@ export async function getQuoteOrRate( const energyFee = 2000 * energyPrice const bandwidthFee = 1100 * bandwidthPrice - networkFeeCryptoBaseUnit = bn(energyFee).plus(bandwidthFee).toFixed(0) + networkFeeCryptoBaseUnit = bn(energyFee) + .plus(bandwidthFee) + .plus(accountActivationFee) + .toFixed(0) } } catch (error) { // For rates, fall back to '0' on estimation failure
