In order to create the first decentralized credit bureau Masa implements a set of soulbound Tokens and non-fungible Tokens (NFTs). The following components are attributed to a users account during each step of the lending lifecycle. Metadata attributed to a soulbound token encrypted and can only be accessed with permission from the owner through the Masa API and Smart Contracts.

The Masa Identity is a soulbound Identity Token that is generated for a user when they sign up to the Masa protocol and includes the following information:

The soulbound Masa Credit Report enables the bridging and aggregation of on and off-chain data in order to create a hybrid decentralized credit report. The Masa credit report can include the following information depending on which region you are located (read a full list of supported countries here):

• Credit Bureau Data
• Bank Transaction Data
• Mobile Money Data
• On-chain Data
• Centralized Exchange Data

Masa Soul Names are non-fungible tokens that can be attached to the Masa soulbound identity. They act as a human-readable address for the Masa soulbound identity.

Masa’s soulbound tokens have their metadata stored in the Masa API which is updated in real time with verified data throughout the lifecycle of the user. The Masa API has the following endpoints available with metadata data schema’s for attribution to the soulbound Tokens URI.
