Branislav Kontur c284a9312a Remove (rococo/westend)-runtime deps from testnet AssetHubs (#1979) 
## Problem

This PR addresses the issue with testnet AssetHub builds, which was
discovered during the execution of `bot bench`.

## Solution

- Removed dependencies on `rococo-runtime` and `westend-runtime`
introduced by [this
PR](https://github.com/paritytech/polkadot-sdk/pull/1234/files#diff-a86375df98e04ca3cce1ea35c40257a222e2d5087f5f528ff33307678b78dc2dR534-R550).
- Replaced `<rococo_runtime::Treasury as PalletInfoAccess>::index()`
with `rococo_runtime_constants::TREASURY_PALLET_ID`.
- Added `check_treasury_pallet_id` to the relay runtimes to ensure that
the constant is aligned with the pallet id.
- Added "Rococo Treasury" to the waived locations (that will not be
charged fees in the executor) for `BridgeHubRococo` (to be aligned with
AssetHubs).

Bridge-hub Parachains

BridgeHub(s) are system parachains that will house trustless bridges from the local ecosystem to others. The current trustless bridges planned for the BridgeHub(s) are:

  • BridgeHubPolkadot system parachain:
    1. Polkadot <-> Kusama bridge
    2. Polkadot <-> Ethereum bridge (Snowbridge)
  • BridgeHubKusama system parachain:
    1. Kusama <-> Polkadot bridge
    2. Kusama <-> Ethereum bridge The high-level responsibilities of each bridge living on BridgeHub:
  • sync finality proofs between relay chains (or equivalent)
  • sync finality proofs between BridgeHub parachains
  • pass (XCM) messages between different BridgeHub parachains

Requirements for local run/testing

# Prepare empty directory for testing
mkdir -p ~/local_bridge_testing/bin
mkdir -p ~/local_bridge_testing/logs

---
# 1. Install zombienet
Go to: https://github.com/paritytech/zombienet/releases
Copy the apropriate binary (zombienet-linux) from the latest release to ~/local_bridge_testing/bin


---
# 2. Build polkadot binary

# If you want to test Kusama/Polkadot bridge, we need "sudo pallet + fast-runtime",
# so we need to use sudofi in polkadot directory.
#
# Install sudofi: (skip if already installed)
# cd <somewhere-outside-polkadot-sdk-git-repo-dir>
# git clone https://github.com/paritytech/parachain-utils.git
# cd parachain-utils # -> this is <parachain-utils-git-repo-dir>
# cargo build --release --bin sudofi
#
# cd <polkadot-sdk-git-repo-dir>/polkadot
# <parachain-utils-git-repo-dir>/target/release/sudofi

cd <polkadot-sdk-git-repo-dir>
cargo build --release --features fast-runtime --bin polkadot
cp target/release/polkadot ~/local_bridge_testing/bin/polkadot

cargo build --release --features fast-runtime --bin polkadot-prepare-worker
cp target/release/polkadot-prepare-worker ~/local_bridge_testing/bin/polkadot-prepare-worker

cargo build --release --features fast-runtime --bin polkadot-execute-worker
cp target/release/polkadot-execute-worker ~/local_bridge_testing/bin/polkadot-execute-worker


---
# 3. Build substrate-relay binary
git clone https://github.com/paritytech/parity-bridges-common.git
cd parity-bridges-common

# checkout desired branch or use master:
# git checkout -b master --track origin/master
# `polkadot-staging` (recommended) is stabilized and compatible for Cumulus releases
# `master` is latest development
git checkout -b polkadot-staging --track origin/polkadot-staging

cargo build --release -p substrate-relay
cp target/release/substrate-relay ~/local_bridge_testing/bin/substrate-relay


---
# 4. Build cumulus polkadot-parachain binary
cd <polkadot-sdk-git-repo-dir>

cargo build --release -p polkadot-parachain-bin
cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain
cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain-asset-hub

How to test local Rococo <-> Wococo bridge

Run Rococo/Wococo chains with zombienet

cd <polkadot-sdk-git-repo-dir>

# Rococo + BridgeHubRococo + AssetHub for Rococo (mirroring Kusama)
POLKADOT_BINARY_PATH=~/local_bridge_testing/bin/polkadot \
POLKADOT_PARACHAIN_BINARY_PATH=~/local_bridge_testing/bin/polkadot-parachain \
POLKADOT_PARACHAIN_BINARY_PATH_FOR_ASSET_HUB_ROCOCO=~/local_bridge_testing/bin/polkadot-parachain-asset-hub \
	~/local_bridge_testing/bin/zombienet-linux --provider native spawn ./cumulus/zombienet/bridge-hubs/bridge_hub_rococo_local_network.toml

cd <polkadot-sdk-git-repo-dir>

# Wococo + BridgeHubWococo + AssetHub for Wococo (mirroring Polkadot)

Init bridge and run relayer between BridgeHubRococo and BridgeHubWococo

Accounts of BridgeHub parachains:

  • Bob is pallet owner of all bridge pallets

Run with script

cd <polkadot-sdk-git-repo-dir>

./cumulus/scripts/bridges_rococo_wococo.sh run-relay

Check relay-chain headers relaying:

Check parachain headers relaying:

Initialize configuration for transfer asset over bridge (ROCs/WOCs)

This initialization does several things:

  • creates ForeignAssets for wrappedROCs/wrappedWOCs
  • drips SA for AssetHubRococo on AssetHubWococo (and vice versa) which holds reserved assets on source chains
cd <polkadot-sdk-git-repo-dir>

./cumulus/scripts/bridges_rococo_wococo.sh init-asset-hub-rococo-local
./cumulus/scripts/bridges_rococo_wococo.sh init-bridge-hub-rococo-local
./cumulus/scripts/bridges_rococo_wococo.sh init-asset-hub-wococo-local
./cumulus/scripts/bridges_rococo_wococo.sh init-bridge-hub-wococo-local

Send messages - transfer asset over bridge (ROCs/WOCs)

Do (asset) transfers:

cd <polkadot-sdk-git-repo-dir>

# ROCs from Rococo's Asset Hub to Wococo's.
./cumulus/scripts/bridges_rococo_wococo.sh reserve-transfer-assets-from-asset-hub-rococo-local

cd <polkadot-sdk-git-repo-dir>

# WOCs from Wococo's Asset Hub to Rococo's.
./cumulus/scripts/bridges_rococo_wococo.sh reserve-transfer-assets-from-asset-hub-wococo-local

Claim relayer's rewards on BridgeHubRococo and BridgeHubWococo

Accounts of BridgeHub parachains:

  • //Charlie is relayer account on BridgeHubRococo
  • //Charlie is relayer account on BridgeHubWococo
cd <polkadot-sdk-git-repo-dir>

# Claim rewards on BridgeHubWococo:
./cumulus/scripts/bridges_rococo_wococo.sh claim-rewards-bridge-hub-rococo-local

# Claim rewards on BridgeHubWococo:
./cumulus/scripts/bridges_rococo_wococo.sh claim-rewards-bridge-hub-wococo-local
