Deep Dive
1. Smart Contract Backends Live (Oct 2025)
Overview: Kusama activated Ethereum Virtual Machine (EVM) and Polkadot Virtual Machine (PVM) backends, enabling developers to deploy Solidity contracts or build custom logic with Substrate-native tooling.
This upgrade merges Ethereum’s developer familiarity with Polkadot’s scalability. EVM support lets projects migrate dApps unchanged, while PVM offers faster execution and lower fees for Substrate-based contracts.
What this means: This is bullish for KSM because it broadens developer reach – Ethereum builders can port apps seamlessly, while Polkadot-native teams gain optimized infrastructure. Users benefit from more dApps and competitive gas fees. (Source)
2. Asset Hub Migration Completed (Oct 2025)
Overview: Kusama finalized its migration to a dedicated Asset Hub, centralizing token creation, transfers, and cross-chain swaps.
The hub standardizes asset management via pallets like Assets and Uniques, replacing legacy modules. It reduces transaction costs by ~37% for token transfers and enables native interoperability with Polkadot’s ecosystem.
What this means: This is neutral for KSM – while it improves usability for existing projects, migration temporarily diverted developer focus from new features. Long-term, streamlined asset flows could attract more parachains. (Source)
3. USDT Support Sunset (Sep 2025)
Overview: Kusama discontinued Tether (USDT) support, freezing remaining tokens after a redemption window.
The decision followed Tether’s strategic exit from low-activity networks. Kusama’s runtime was updated to block USDT transactions, redirecting liquidity to DOT-backed stablecoins like AUSD.
What this means: This is bearish for KSM in the short term, as DeFi protocols lost a major stablepair. However, it aligns Kusama closer to Polkadot’s native assets, reducing reliance on external stablecoins. (Source)
Conclusion
Kusama’s upgrades emphasize cross-chain scalability (EVM/PVM) and self-sufficient liquidity (USDT sunset), balancing experimentation with ecosystem cohesion. With smart contracts now live, will developer activity reverse KSM’s 30% annualized price decline?
