Introduction

Our Auth product is a seamless and secure solution for enabling direct account-to-account transfers between custodial accounts (ie, exchanges, fintechs, etc) and non-custodial accounts.

Backed by a deep network of supported venues, Auth eliminates manual and error-prone transfer steps leading to fragmented user experiences. Our platform handles secure authentication, initiates transfers, and ensures visibility and adherence to key compliance/AML standards. Offered through easy-to-integrate SDK's, Auth is built for scale, security, and seamless user journeys.

Auth Lite vs. Auth Validate

You can choose between 2 versions of Auth:

🔐

Auth Lite

1. Purely a tech connectivity product, there is no account-matching validation performed between the end user account and the external account being connected
2. Enables faster and more flexible integrations with minimal friction for end users
3. Best suited for low-risk or closed-loop environments where account ownership verification is not required

✔️

Auth Validate

1. Performs account-matching between the KYC’d customer record and the external account being connected
2. Adds a layer of identity verification to reduce the risk of misdirected transfers or fraud
3. Supports compliance with internal policies or regulatory requirements requiring account ownership validation

Configuration Rules

You have the ability to tailor your Auth setup per your own preferences. See below list of configuration options:

Account Match Logic

zerohash can perform account matching between the user in our system and the corresponding account within the external exchange system.

Logic

By default, our out-of-the-box name matching logic performs a standard comparison of First Name and Last Name fields. We apply a string similarity algorithm called Jaro-Winkler, which generates a score between 0 and 1:

• A score of 1.0 indicates a perfect match
• Lower scores reflect less similarity between the names

We recommend a default threshold of 0.75 (ie, 75%), but this value is fully configurable based on your organization’s needs and risk tolerance.

Customizations and support

If you have further questions about the algorithm or need guidance on configuring the appropriate match threshold, please reach out to your zerohash representative. They can connect you with our Product, Engineering, or Compliance teams for more in-depth support.

Different applications of Auth

Auth can be offered as a standalone product, or bundled within one of our Move products (Payouts, Payins, or Account Funding).
