Deep Dive
1. Smart Contract Deployment (October 2025)
Overview: Kusama will activate Polkadot Virtual Machine (PVM) and Ethereum Virtual Machine (EVM) backends, allowing developers to deploy Solidity contracts unchanged or experiment with next-gen compute models.
This upgrade bridges Ethereum’s developer ecosystem with Kusama’s experimental environment. The EVM compatibility lowers onboarding barriers for Ethereum-native projects, while PVM introduces a novel execution layer for advanced use cases like privacy-focused dApps.
What this means: This is bullish for KSM because it broadens developer appeal, potentially increasing network activity and parachain demand. Users gain access to familiar tools while benefiting from Kusama’s faster iteration cycle.

2. 10M DOT Developer Bounty (July 2025)
Overview: A 10M DOT fund was announced to accelerate development across three tracks: zk-proof integrations, blockchain gaming, and cross-chain infrastructure.
The bounty targets high-impact areas like zero-knowledge applications (e.g., privacy-preserving asset transfers) and gaming SDKs. Submissions are reviewed by Web3 Foundation technical teams, with grants awarded quarterly.
What this means: This is neutral for KSM as it primarily incentivizes Polkadot-focused innovation. However, successful experiments on Kusama could later migrate to Polkadot, reinforcing Kusama’s role as a testing ground.

3. USDT Support Sunset (September 2025)
Overview: Tether discontinued USDT redemptions on Kusama, requiring code updates to freeze remaining tokens and redirect liquidity via bridges to Polkadot.
The change reflects low USDT usage on Kusama (<$240k circulation) and prioritizes networks with higher stablecoin demand. Node operators implemented patches to block USDT transactions post-deadline.
What this means: This is bearish for short-term liquidity but neutral long-term. It streamlines ecosystem focus while encouraging migration to more active chains like Polkadot.

Conclusion
Kusama continues balancing experimentation with practicality—bolstering developer tools while pruning underused features. The October smart contract launch could reignite parachain activity, but will builders prioritize Kusama over Polkadot’s stability? Monitor KSM’s developer activity metrics post-upgrade for adoption signals.
