Wu Shuo learned that Tempo, a payment public chain jointly launched by Stripe and Paradigm, announced the launch of a native token standard TIP-20, which is specifically designed for stablecoins and payment use cases. It is based on the existing ERC-20 standard on Ethereum and EVM-compatible chains, and is fully backward compatible. On the basis of ERC-20, it adds transfer notes, compliance controls, and reward distribution functions. The TIP-20 standard allows for the issuance of stablecoins tailored to specific payment use cases while meeting operational and compliance requirements. Any USD-denominated TIP-20 stablecoin can be used to pay transaction fees on Tempo. In the future, Tempo plans to support using non-USD stablecoins to pay fees.
