TRON Fee Delegation Ledger Mechanics
Gasless TRC-20 USDT uses standard ERC-2612 / TRC-2612 permit or relayer delegation architectures. The user signs an off-chain transfer authorization. The relayer broadcasts the transaction, paying the Energy & Bandwidth in TRX, and receives a delegated fee cut directly from the transferred USDT balance.
1 TRX = 1,000,000 Sun
Base Energy Cost = Energy × Price (Sun)
Rental Discount = Native Cost × (1 - Discount)
Relayer Margin = Fee (USDT) - Relayer Cost (USD)
