What exactly leaves Tron as WETH?
WETH is a contract representation on Tron with 18 decimals at TXWkP3jLBqRGojUih1ShzNyDaN5Csnebok. TRX, not WETH, pays gas unless both symbols are the same. A Tron source uses a T-address plus bandwidth and energy accounting; TRX covers resource or fee needs for native or TRC-20 transfer execution. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
