| User | Every individual user and every person in a business entity has a unique user_id. User ID is used to identify the user in the Byzantine ecosystem and to update user personal information. |
| Entity | A legal entity. Every business user of Byzantine has a unique entity_id. At least one user account needs to be tied to each legal entity to be able to make transactions. An entity can be found via any account ID that is tied to it. |
| Account | Every individual and business user of Byzantine has an account, associated with a unique account_id. Accounts can be tied to legal entities. |
| Wallet | A wallet is the user’s blockchain access point: it stores their assets and enables transactions. The wallet is where a user account’s vault shares are held. If a user doesn’t already have one, a secure wallet is automatically created and embedded in their account during onboarding. One account is associated with at least one wallet. |
| Vault | Byzantine products, like Byzantine Prime USDC, are smart contracts known as vaults. These smart contracts are blockchain-based code that automatically handles all administration work surrounding a user’s deposit. These vaults are what make Byzantine’s high security and non-custodial nature possible. |
