# Overview Gasless transactions are facilitated by the [RallyTransact](https://docs.rallyprotocol.com/unity/getting-started/overview#rallyprotocol), functioning as the fully hosted transactions infrastruture for signing, validating, and relaying transactions to the blockchain. RallyTransact removes the requirement for developers to manage nodes, bundlers, and deploy contracts. Additionally, RallyTransact takes care of funding balances for gasless transactions, monitors transactions, and provides enhanced secops. Although RallyMobile provides dev friendly APIs to interact with the transaction infrastructure, RallyTransact can also be used [outside of the SDK](https://docs.rallyprotocol.com/unity/gasless-transactions/using-without-embedded-wallets). Devs can send transactions from their backend, web dapp, desktop, etc and get all the benefits listed above. ### --- # 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.
