What exactly leaves Ethereum as WETH?
WETH is a contract representation on Ethereum with 18 decimals at 0xb1A7F8b3AdA1Cbd7752c1306725b07D2F8B4e726. ETH, not WETH, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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.
What exactly arrives on Optimism as TRX?

An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. Native TRX receipt belongs to a Tron address and can support network resources; tokenized TRX on another ledger cannot supply Tron bandwidth or energy.
Why does the WETH to TRX direction matter?
