## Summary Asset bridging support for AssetHub**Rococo** <-> AssetHub**Wococo** was added [here](https://github.com/paritytech/polkadot-sdk/pull/1215), so now we aim to bridge AssetHub**Rococo** and AssetHub**Westend**. (And perhaps retire AssetHubWococo and the Wococo chains). ## Solution **bridge-hub-westend-runtime** - added new runtime as a copy of `bridge-hub-rococo-runtime` - added support for bridging to `BridgeHubRococo` - added tests and benchmarks **bridge-hub-rococo-runtime** - added support for bridging to `BridgeHubWestend` - added tests and benchmarks - internal refactoring by splitting bridge configuration per network, e.g., `bridge_to_whatevernetwork_config.rs`. **asset-hub-rococo-runtime** - added support for asset bridging to `AssetHubWestend` (allows to receive only WNDs) - added new xcm router for `Westend` - added tests and benchmarks **asset-hub-westend-runtime** - added support for asset bridging to `AssetHubRococo` (allows to receive only ROCs) - added new xcm router for `Rococo` - added tests and benchmarks ## Deployment All changes will be deployed as a part of https://github.com/paritytech/polkadot-sdk/issues/1988. ## TODO - [x] benchmarks for all pallet instances - [x] integration tests - [x] local run scripts Relates to: https://github.com/paritytech/parity-bridges-common/issues/2602 Relates to: https://github.com/paritytech/polkadot-sdk/issues/1988 --------- Co-authored-by: command-bot <> Co-authored-by: Adrian Catangiu <adrian@parity.io> Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com>
Bridge Relayers Pallet
The pallet serves as a storage for pending bridge relayer rewards. Any runtime component may register reward
to some relayer for doing some useful job at some messages lane. Later, the relayer may claim its rewards
using the claim_rewards call.
The reward payment procedure is abstracted from the pallet code. One of possible implementations, is the
PayLaneRewardFromAccount, which just does a Currency::transfer
call to relayer account from the relayer-rewards account, determined by the message lane id.
We have two examples of how this pallet is used in production. Rewards are registered at the target chain to compensate fees of message delivery transactions (and linked finality delivery calls). At the source chain, rewards are registered during delivery confirmation transactions. You may find more information about that in the Kusama <> Polkadot bridge documentation.
