Runtime Upgrade 1.24.0: DeFi Hub, Weights & Fees

Following the recent Kintsugi upgrades, there are many new changes to introduce to the Interlay network.

DeFi Hub

The Bitcoin DeFi Hub introduces the following pallets:

  • DexGeneral is a Uniswap v2-style AMM
  • DexStable is a Curve v1-style AMM
  • Loans is Compound v2-style lending protocol

Please note that this upgrade does not setup the pools, markets or incentives which will be proposed separately.

Weights & Fees

Many breaking changes were introduced to improve the security of the network and increase usability:

  • Cumulus, Polkadot and Substrate dependencies have been updated to 0.9.40.
  • Bitcoin type parsing was removed, consumers will do this off-chain and submit concrete types. This was necessary for complexity estimation and because we previously identified several bugs in the code responsible for parsing.
  • Storage entries are now bounded to provide the relay chain with accurate proof sizes.
  • Benchmarks now measure the worst-case complexity to limit the possibility of Denial-of-Service (DoS) attacks - the weights have been measured on standard node hardware.
  • The Treasury pallet was removed as it served no useful purpose, users may now use the spend_from_treasury extrinsic to construct spending proposals.
  • New events were introduced in VaultRegistry, DexGeneral and Democracy for downstream usage.
  • Implements new "bring-your-own-fee" architecture which allows consumers to pay for transaction execution in currencies other than INTR, it does this by swapping the input token using our AMM.
