PolyFlow announced its integration with Solana Attestation Service to promote the construction of on-chain credentials and payment trustworthiness, and the first application to achieve SIM authentication in the DePIN project. In the future, it will be expanded to DeFi, supply chain finance and other scenarios to accelerate the implementation of global crypto payment scenarios. On May 23, PolyFlow, an innovative PayFi protocol, announced the official integration of the Solana Attestation Service (SAS) at the Solana Accelerat e conference in New York. Liquidity management and tokenized payment scenarios set a new standard. It is reported that PolyFlow has taken the lead in applying this solution to the DePIN open wireless network project ROAM, realizing decentralized SIM real-name authentication and automatic eSIM activation, and plans to expand to DeFi credit scores, supply chain financial vouchers and other scenarios. PolyFlow said that in the future, it will continue to build a next-generation PayFi infrastructure that seamlessly connects traditional payments, DeFi and physical assets, and accelerate the implementation of global crypto payment scenarios.
