On May 24, PolyFlow announced the integration of Solana’s Attestation Service, marking a significant advancement in the development of its PayFi infrastructure. This integration was unveiled during the annual Solana Accelerate Conference presentation. PolyFlow’s CFO, Chuck Zhang, highlighted the real-world applications of decentralized finance enabled by this collaboration. The integration establishes tamper-proof proofs and identity credentials on the Solana blockchain network, aiming to enhance trust and verification in Web3 payment systems. This move underscores a growing trend toward secure digital payment solutions.

The integration extends beyond payments to include supply chain finance and trade document verification. Businesses can now anchor invoice authenticity proofs and warehouse receipts on-chain, allowing users to release funds faster by verifying asset legitimacy. Cross-border payments become more efficient due to clear trade data records, significantly reducing the risk of fraud in global trade finance operations. Verified document credentials foster trust among trading partners and financial institutions, highlighting the practical benefits of a secure PayFi infrastructure. This system enables more efficient capital flow and strengthens supply chain resilience against fraud.

A key use case involves SIM verification through collaboration with the Solana network. Users who complete KYC through PolyFlow’s Payment ID receive instant eSIM activation. This process eliminates repeated identity checks by leveraging on-chain stored credentials. The Solana Attestation Service framework secures KYC proofs without exposing personal details, ensuring fraud-resistant issuance of digital SIMs across decentralized networks. Service providers can validate user identities instantly without repeated verification steps, supporting faster user onboarding and reducing friction in telecom services. This highlights the benefits of cross-industry collaboration in digital identity management.

The addition of the Solana Attestation Service extends PolyFlow’s Payment ID capabilities across chains. The Payment ID system now acts as a multi-chain credit passport for user profiles, recording credit events like loan repayments and collateral performance on-chain. Anchored credentials support faster access to services like lending and supply chain finance. On-chain records also reduce fraud risk by providing verifiable transaction histories. This integration enhances cross-network credit scoring and verification in decentralized finance platforms, benefiting users with unified profiles that simplify identity checks and reduce repeated verifications.

Individual users gain practical advantages by linking Web2 identity data and decentralized services. The Payment ID allows storing verified credentials in a privacy-preserving manner. Users can present credentials like KYC status and credit scores without revealing extra data. Zero-knowledge proofs maintain compliance while protecting user privacy across applications. This approach simplifies interactions on DeFi platforms while adhering to regulatory standards. Seamless credential sharing reduces reliance on centralized intermediaries for identity checks, fostering trust by enabling secure and private data exchanges. It bridges legacy systems and modern blockchain platforms, creating seamless integration between environments. Users experience smoother verification across services without repeated manual steps.

PolyFlow’s Payment ID transforms crypto wallets into versatile identity and payment tools. Integrated wallets support verifiable credentials and zero-knowledge proof technology seamlessly. They can verify qualifications like age or creditworthiness without disclosing full details, aligning with goals for secure and privacy-respecting everyday Web3 finance activities. Wallet users benefit from reduced verification steps across services and platforms. The solution bridges the gap between simple asset storage and identity management tools, showcasing the potential of combining identity credentials with digital wallets effectively. This improvement supports wider adoption of DeFi services by simplifying the user experience.

The partnership between PolyFlow and Solana Attestation Service promotes a secure payment ecosystem. Combined capabilities address challenges in cross-border lending and supply chain finance. Users gain traceable and tamper-proof transaction records within a single platform. The collaboration lays the groundwork for expanded decentralized application adoption in daily finance. As the infrastructure evolves, it may support broader Web3 payment use cases. This development signifies progress toward a unified, transparent, and reliable financial network.
