WalletAPI is an implementation for accounting systems to keep track of account balances and allow various complex transactions between them.
WAPI aims to solve many complex and annoying problems when trying to keep trakc of user balances do transactions in a reliable and performant manner.
WAPI Client is a library allowing to connect to WAPI Server over WebSockets and simplifies the adoption of WAPI into a project by providing simplified interfaces to various functionality.
A counter of value that can be transferred between Wallet entities. Usually some form of currency.
Entity which is able to hold and transfer tokens within the system. Is usually in one-to-one relation with some entity in Users system.
Entity describing the relationship between a wallet and token. Balances usually can't be negative for regular wallets nor can they be positive for Token wallets.
An entity describing transfer of tokens from one wallet to another. The transfer of value is always positive and results an amount of Token being deducted from one Wallet and added to another Wallet.
An entity grouping transfers together and allowing them to be treated as a single entity. Immitating a Transaction with long lifetime you can set up a complex pending TransferGroup and then complete or cancel it with a single transaction.
All Balances within WAPI will always sum to 0. It means no value is ever created within WAPI nor will it leave it is only redistributed between wallets.
Transfers can only ever be appended to the list. Inserting transfers into random locations in the history is not permitted thus any new transfer must be the latest transfer within the system.
Most entities have only a limited set of properties that can be updated. Most things are immutable. For customization and integration to Users system metadata JSON fields are provided which to hold customer specific data.
