# Transactions ### Private Transactions RAILGUN enables encrypted private transactions through [Shielding](/developer-guide/wallet/transactions/shielding.md). Once assets are shielded into the RAILGUN contract, there are several options: 1. [Transfer ](/developer-guide/wallet/transactions/private-transfers.md)tokens privately to another RAILGUN wallet. 2. Use a [cross-contract call](/developer-guide/wallet/transactions/cross-contract-calls.md) to interact privately with an external smart contract. 3. [Unshield](/developer-guide/wallet/transactions/unshielding.md) tokens into any public wallet. These transactions achieve a level of privacy, as their contents cannot be read by an external observer. For example, private transfers show no details of the tokens or amounts sent[ in Etherscan](https://etherscan.io/tx/0x37c555c4add7b4372a234d34e387ad1da6f81fd3c7b860d951f02279cd8e4727). ### Broadcasters In order to achieve full anonymity, RAILGUN uses a network of Broadcasters to submit transactions. Broadcasters are external wallets that sign transactions on a user's behalf. Broadcasters pay gas fees for users, and they receive ERC-20 tokens as fees for the service. If you want to send transactions through a Broadcaster, use [@railgun-community/waku-broadcaster-client](https://github.com/Railgun-Community/waku-broadcaster-client) --- # 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.
