Calculator FAQs
How are TRC20 vs ERC20 fees calculated?
TRC20 fees rely on Tron Energy & Bandwidth burning, averaging ~$1.50 to $3.00. ERC20 fees depend on Ethereum base gas price (Gwei) and network congestion.
Why does validity duration affect transaction propagation?
Longer validity durations (e.g. 72h) require higher mempool persistence node settings, ensuring the transaction remains broadcasted across nodes.
Can I simulate fees for zero-confirmation transactions?
Yes! Select your target network and adjust the parameters to see expected mempool broadcast latency and node acceptance costs.
