# Schema: Polkadot SDK PRDoc Schema (prdoc) v1.0.0 # See doc at https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/prdoc/schema_user.json title: Implement transaction_unstable_broadcast and transaction_unstable_stop doc: - audience: Node Dev description: | A new RPC class is added to handle transactions. The `transaction_unstable_broadcast` broadcasts the provided transaction to the peers of the node, until the `transaction_unstable_stop` is called. The APIs are marked as unstable and subject to change in the future. To know if the transaction was added to the chain, users can decode the bodies of announced finalized blocks. This is a low-level approach for `transactionWatch_unstable_submitAndWatch`. crates: [ ]
