List of content of this Runtime Upgrade

We are excited to announce the inclusion of Pools in the Centrifuge runtime, a significant enhancement to our platform. As a result, investors will now have the opportunity to invest in RWA Pools on the purpose-built Centrifuge chain, which operates under the robust security umbrella of Polkadot. This new feature complements the existing Tinlake on Ethereum, expanding investment options for our valued users.

• Add pallets for PoolRegistry, PoolSystem, Permissions, Investments and InterestAccrual (PR #1233)
• Refactor pallet-loans to allow better scalability in loans. Instead of choosing between fixed loan types, they can now be composed with different valuations/restrictions/schedules—improvements in the written-off systems and a lot of simplifications to reason easier about loans as a borrower (PR #1180)
  • For more details, please check the corresponding specification
• Significantly improved interest rate accrual and NAV update efficiency (PR #1157)
• Added new proxy type PermissionManagement which will be used for adding new investors by onboarding API (PR #1197)

Asset Registry Update

When we first added XCM to our runtimes (first Altair and later Centrifuge), the first token we supported was Acala’s AUSD and for that we just added AUSD as a hardcoded variant of our CurrencyId enum type. That type enumerates all the currency ids that the Centrifuge chain knows about or is able to handle. Later, improving our XCM setup, we introduced the ORML asset registry for two purposes:

1. So that we could support new tokens through XCM by simply registering them in the asset registry instead of hardcoding them in the CurrencyId type and thus not require runtime upgrades to support new tokens.
2. So that we had a standardised way of querying metadata for all tokens that Centrifuge handles, i.e, both native tokens like CFG and Tranche tokens, as well as “foreign” tokens like AUSD, USDC, etc. This motion is now a step into cleaning up that first legacy, “hardcoding”-based approach; we do that by dropping those hardcoded currency variants (AUSD and KSM (the latter only applicable on Altair)) and have them registered as Currency::ForeignAsset(<asset_id>) in the asset registry instead. The next step will be to migrate all balances that are now under CurrencyId::AUSD and CurrencyId::KSM to CurrencyId::ForeignAsset(<aUSD_asset_id>) and CurrencyId::ForeignAsset(<ksm_asset_id>), respectively.

For more context, please check Issue #886.
