Polygon has announced the introduction of USDC tax refunds at Milan, Rome, and Venice airports during the 2026 Winter Olympics. This initiative allows travelers to receive tax refunds in the form of USD Coin (USDC), a stablecoin pegged to the US dollar, providing a seamless and efficient refund process. The move is part of Polygon's efforts to enhance the use of digital currencies in everyday transactions, particularly in high-traffic areas like international airports during major events.
