Tron to Optimism: TRC-20 and EVM boundary
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. 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. Tron and Optimism use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.
