Main changes: - Removed events when creating or updating assets on L2, so this data is removed from disco. - Expanded registerAsset with new parameters priceDecimals , loanToValue , liquidationThreshold , liquidationFactor , and liquidationFee to move to a more collateral-oriented design. - Some code refactor like additional sanity checks on pubkey and moving asset validation logic into a separate function.
