# Transactions

## How do I prepare transaction requests?

In order to send transaction requests to CKBull Wallet users, the [**Lumos**](https://github.com/ckb-js/lumos) library must be used. Specifically, it is necessary to provide a JSON object of type **TransactionSkeletonType** containing the **outputs** corresponding to the reason for the transaction.

When the user receives the request and proceeds to sign it, the rest of the fields of the transaction (cellDeps, inputs, witnesses, etc.) will be **filled in automatically**, once the transaction is signed, it will be sent.
