PayFi Protocol PolyFlow integrates Solana Attestation Service to build next-generation consumer payment infrastructure

On May 23, it was announced that the innovative PayFi protocol PolyFlow officially integrated the Solana Attestation Service (SAS) at the Solana Accelerate conference in New York. The two parties will jointly promote the credibility of on-chain credentials and payments, setting new standards for cross-border settlement, liquidity management, and tokenized payment scenarios. It is reported that PolyFlow has already applied this solution to the DePIN open wireless network project ROAM, achieving decentralized SIM real-name authentication and eSIM automatic activation, and plans to expand to scenarios such as DeFi credit scoring and supply chain financial credentials. PolyFlow stated that in the future, it will continue to build the next-generation PayFi infrastructure that seamlessly connects traditional payments, DeFi, and physical assets, accelerating the implementation of global crypto payment scenarios.
