enable TEER on Asset Hub and KSM on self

closes #268 closes #272

this enables

reserve transfer of ROC from relay to Integritee and back to relay
teleport of TEER to AssetHub and back

strategy:

we use pallet_assets, not orml_tokens (see #260 for abandoned work using orml-tokens)

regression testing:

[x] chopsticks xcm with Karura

testing

zombienet

zombienet-linux-x64 spawn --provider native zombienet/rococo-local-with-integritee-and-asset-hub.toml
./scripts/hrmp-helper.sh

send ROC between Relay <> Integritee

note preimage to register ROC as an asset on Integritee, set metadata and register its multilocation

execution should result in Events:

assets.forceCreated
assets.MetadataSet
assetRegistry.ReserveAssetRegistered

if testing with polkadot >= 1.7 binaries, need to downgrade safeXcmVersion to V3 on relaychain

send TEER to Asset Hub

send 1 ROC to sovereign account 2015 on AH

note preimage to register TEER as foreign asset on Asset Hub

you should see these events on AH

foreignAssets.Created
foreignAssets.MetadataSet

teleport 1 TEER from Alice@Integritee to Alice@AH (and attach 1mROC to pay fees on AH)

this should result in events

assets.Burnedon Integritee
foreignAssets.Issued on Asset Hub

what also works:

transfer 100mROC from Alice on Integritee to Alice on AH

send TEER back

send 10 TEER to AH sibling account on integritee to pay XCM fees

teleport 200mTEER from alice on AH to Charlie on Integritee

you should see balances.Endowedevent or, if the recipient exists, balances.Deposit (hidden in system events. check block!)

fees

Fees are quite complex to understand with XCM.

use ./scripts/dump-essential-balances.sh to compare pre/post balances
