Sumsub

• Name: Sumsub
• URL: https://sumsub.com/
• Category: identity verification / compliance orchestration / Travel Rule / crypto transaction-monitoring infrastructure
• Summary: Sumsub is a broad identity-and-compliance platform that is worth cataloging as crypto-adjacent operating infrastructure rather than as a generic KYC vendor. Its official materials show a stack spanning user verification, business verification, transaction monitoring, fraud prevention, workflow orchestration, API / SDK integrations, and a substantial crypto-specific layer for wallet screening, Travel Rule messaging, VASP due diligence, and unhosted-wallet verification. The strongest differentiator in this pass is how clearly the docs reveal a crypto-compliance control plane sitting underneath the broader identity product.
• What it does:
  • Verifies users and businesses, manages identity workflows, and exposes those checks through SDK, API, and no-code / low-code integration paths
  • Monitors transactions, including crypto-wallet screening and crypto-specific risk checks before blockchain transfers
  • Runs Travel Rule workflows with protocol routing, VASP attribution, sanctions / watchlist checks, and Sunrise / interoperability handling
  • Supports unhosted-wallet verification through cryptographic-signature flows and microtransaction / “Satoshi test” flows
  • Provides VASP AML screening and can incorporate third-party crypto-intelligence or RegTech data sources into decisioning and reporting
• Key claims:
  • The homepage says Sumsub is a configurable verification platform serving 4,000+ clients and supporting user verification, business verification, transaction monitoring, and fraud prevention on one platform
  • The docs overview recommends dashboard-first setup, verification-level creation, SDK or API go-live flows, and webhook-based result handling, which confirms a real operator-facing platform rather than a marketing-only surface
  • The Travel Rule overview says Sumsub’s checks are part of Transaction Monitoring, support 8,000+ virtual assets, and include multi-level risk evaluation plus protocol-based counterparty data exchange
  • The protocols page says Sumsub can route Travel Rule data directly, via TRP, CODE, GTR, or Sygna Bridge, and can fall back to email when the counterparty VASP is outside known protocol networks
  • The crypto-monitoring page says Sumsub can screen wallet addresses with integrated crypto-intelligence providers including Crystal, Chainalysis, Elliptic, TRM Labs, and Merkle Science
  • The unhosted-wallet-verification docs say Sumsub supports both digital-signature verification and microtransaction verification for self-hosted wallets
  • The VASP AML screening docs say Sumsub uses third-party RegTech data such as ComplyAdvantage and lets customers configure sanctions, PEP, adverse-media, and other screening controls
• Whitepaper: No canonical Sumsub whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official homepage plus the docs corpus for overview, Travel Rule, crypto monitoring, protocol routing, unhosted-wallet verification, and VASP AML screening; see ../whitepapers/sumsub-primary-sources-2026-05-01.md.
