Altair Council Motion 105: Runtime Upgrade 1034

The Altair council has just submitted a motion (Council Motion 105 ) for upgrading the Altair chain to Runtime version 1034.

After a long time of silence, we finally prepared a runtime upgrade for Altair which bumps the spec version from 1027 to 1034. Since the last upgrade occurred mid 2023, the release notes span over 4 Centrifuge releases (1020, 1023, 1024 and the upcoming 1025).The quick summary would be that we re-synchronized Altair with Centrifuge.

All features which have existed on Centrifuge, will be live on Altair as well. In order to achieve that, we are hard resetting a plurality of modules which are empty anyways. The modules are Loans, InterestAccrual, PoolSystem, Investments. Moreover, we are removing the NFT Sales and Migration Pallets.


  • Enable Liquidity Pools (exactly as on Centrifuge Chain)
  • Upgrade to XCMv3
  • Register various USDC variants
  • Switch to relative treasury inflation of annual 3% of total issuance based on this RFC
    • Does not include burning of treasury funds, needs to be appended to proposal manually

Important for node operators
