PolyFlow Integrates Sumsub to Power Frictionless KYC for On-Chain Identity and Payments
PolyFlow is proud to announce a strategic integration with Sumsub, the leading identity verification (IDV) platform trusted by thousands of top-tier crypto companies worldwide.
Through this partnership, PolyFlow will leverage Sumsub ID, part of the company’s’ Reusable Identity product suite, to streamline user onboarding for its Payment ID (PID) system and broader PayFi infrastructure. This means Web3 users can verify their identity once and reuse those credentials across the PolyFlow ecosystem — reducing friction, accelerating access, and maintaining regulatory-grade compliance.
Why it matters
Today, most users in the crypto space are forced to complete KYC checks multiple times across different platforms — causing frustration and drop-offs.
Sumsub ID allows individuals to pre-verify once and reuse their identity data across multiple services. It can reduce onboarding time by up to 50% and boost conversion rates by 30%, offering businesses a more efficient route to compliance while improving user experience.
With the Sumsub × PolyFlow integration, users can:
- Complete one-time KYC via Sumsub
- Automatically receive a PID credential anchored on the Solana blockchain via SAS
- Reuse this verified identity for use cases such as:
⭐️ eSIM activation in DePIN networks like ROAM
⭐️ DeFi credit scoring and undercollateralized lending
⭐️ On-chain supply chain financing
This creates a seamless user journey — where identity becomes portable, verifiable, and programmable.
How it works
The integration flows as follows:
- User completes KYC via Sumsub within PolyFlow
- PID credential is issued and recorded via Solana Attestation Service (SAS)
- User’s on-chain credential is verifiable by third parties, enabling automatic eSIM activations or DeFi loans
- No repeat KYC is needed for any service using the same infrastructure
This unlocks a future of frictionless identity across DeFi, CeFi, and real-world use cases.
