# Zebec Bulk Client The `ZebecBulkClient` is a TypeScript class designed to interact with Ethereum smart contracts for bulk transfers in the Zebec protocol. ### Overview The `ZebecBulkClient` class is designed to interact with two key contracts in the Zebec protocol: `BulkTransfer` and `Core`. These contracts are used to manage bulk transfers of tokens. The class provides methods to perform actions such as initializing bulk transfers, updating bulk transfers, and withdrawing funds from bulk transfers. ### Test Code The [test code](https://github.com/Zebec-protocol/bnb-zebec-sdk/tree/main/test/integration/bulk) can also serve as a reference for how to use the `ZebecBulkClient` class in practice.[ ](#user-content-fn-1)[^1] [^1]: --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
