Sumvin is a white-label financial platform API. It handles user accounts, multi-chain wallets, identity verification, and configurable onboarding — so you can build identity-anchored financial products without the infrastructure.

What You Can Build

DomainCapabilities
Accounts & IdentityUser registration, multi-provider auth, phone verification, KYC
Wallets and Safe (multisig) wallets across EVM chains
AssetsMulti-chain asset balances and portfolio tracking
OnboardingStep-based flows with per-platform configuration

​
How It Fits Together

Users sign up through your app. The Platform API creates their account, runs them through a configurable onboarding flow (phone verification, KYC, wallet setup), and provisions a Safe smart account wallet as their on-chain identity anchor. From there, your app can manage wallets, query balances, and use the Sumvin Identity Service to issue verifiable credentials to third parties.
