- CoinFamily/UnderlyingAsset enums in correct K-section
- KatanaEth/KatanaEthTestnet network classes
- katanaeth/tkatanaeth coin entries with SHARED_EVM_SDK feature set
- ofckatanaeth/ofctkatanaeth OFC entries
- networkFeatureMapForTokens EIP1559 support
- environments.ts explorer baseUrls
- expectedColdFeatures fixture in correct K-section
