The zerohash SDKs let you embed regulated crypto, payments, and onboarding flows directly into your product. Each SDK is a drop-in component that handles the regulated surface such as KYC, custody disclosures, signing, and compliance copy so your team can focus on the product wrapper around it.

Available SDKs

Onboarding SDK - KYC and identity verification widget
Auth SDK - link wallets with popular exchanges
Account Funding Deposits SDK - enable crypto payouts to your platform account
Account Funding Withdrawals SDK - enable withdrawals in crypto from your platform account
Payins SDK - accept payments via the Auth payins flow
Payouts SDK - disburse funds via the Auth payouts flow
Mobile SDKs - Native iOS / Android wrappers

Choosing an SDK

Partners can start with the Onboarding SDK to satisfy KYC requirements, then layer on Buy/Sell, Payins, or Payouts depending on the use case. The SDKs share a common authentication scheme and theming layer (see Appearance & Branding) so adding a second SDK once the first is integrated is a small lift.

If your flow lives entirely server-side or you need finer control than the embedded widgets allow, use the REST API directly - see the API Reference and Recipes.
