Polygon to Tron: TRC-20 and EVM boundary
A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A Tron receipt belongs to a T-address as native TRX or the quoted TRC-20 contract; later activity consumes Tron resources or TRX fees. Polygon and Tron use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.
