The zerohash SDKs let you embed regulated stablecoins/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.

ℹ️ Note: All visuals and screenshots from the SDK documentation are conceptual only. Our SDKs are constantly updated and visuals may not reflect the current experience.

Available SDKs

• Onboarding SDK - KYC and identity verification widget
• AUTH SDK - link wallets with popular exchanges
• Account Funding Deposits SDK - enable stablecoins/crypto funding to your platform account that are automatically converted to fiat upon receipt
• Account Funding Withdrawals SDK - enable fiat-funded withdrawals in stablecoins/crypto from your platform account to user exchanges or wallets
• Crypto Deposits SDK - enable stablecoins/crypto funding to your platform account that are not automatically converted to fiat: assets remain in their original deposit type
• Crypto Withdrawals - enable native stablecoins/crypto withdrawals to user exchanges or wallets
• 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.
