# Some P\<\>K bridge updates

## Rococo\<\>Wococo

- BridgeHubRococo parachain (BHR) and BridgeHubWococo parachain (BHW) merged to cumulus and live on Rococo and Wococo - the live runtimes include all bridge pallets with full functionality
- Bridge Relayers are deployed and live for bridging BHR\<\>BHW
- Asset transfer fully working between Rockmine2 and Wockmint - not yet merged because Rockmine2 is actually Statemine runtime code deployed on Rococo so we will only be able to merge this after full audit - but the custom runtimes are deployed on live R\<\>W [from this branch](https://github.com/paritytech/cumulus/tree/bko-transfer-asset-via-bridge)
- Bi-directional asset transfers use XCM Reserve Asset Transfer underneath, but are exposed through [transfer\_asset\_via\_bridge](https://github.com/paritytech/cumulus/blob/7838a2a55f95dd4fa94f0f1c8a8c5fb0977c9457/parachains/pallets/bridge-transfer/src/lib.rs#L311) extrinsic/call from the [bridge-transfer](https://github.com/paritytech/cumulus/tree/bko-transfer-asset-via-bridge/parachains/pallets/bridge-transfer) pallets deployed on both Rockmine2 and Wockmint
- **TLDR is R\<\>W bridge fully up and running, including asset transfer between Rockmine2\<\>Wockmint**
- Security audit is under way; once we finish that, we want to run a public bug bounty on R\<\>W bridge

## Polkadot\<\>Kusama

- BHP and BHK system parachains are live producing empty blocks (no bridging pallets deployed yet)
- BHP and BHK runtimes full bridging configuration is done ([PR here](https://github.com/paritytech/cumulus/pull/2528)) currently pending review and security audit
- Statemine and Statemint runtime changes are also ready ([PR here](https://github.com/paritytech/cumulus/pull/2013)) currently pending review and security audit
- Full BHP & BHK development & deployment plan is detailed [under this milestone](https://github.com/paritytech/parity-bridges-common/issues/1730)
- **TLDR is once we complete R\<\>W security audit and Bug Bounty we’ll start deploying P\<\>K bridge**

## Demo

R\<\>W asset transfer demo coming very soon.

## Roadmap

We have created [this roadmap](https://github.com/orgs/paritytech/projects/27/views/11) where each card is an important milestone containing all the juicy details within.

Big shout-out to the bridges team ❤ for all the good progress here, with a very special thanks to @bkontur and @svyatonik for delivering by the truckload 🤘
