Deep Dive
1. Delayed Upgrade Penalty Ramp-Up (December 2025)
Overview: This is an ongoing, automated adjustment to the upgrade contract. It adds a financial penalty for users who have not yet swapped their legacy MKR tokens for SKY, encouraging full participation in the new system.
The code enforces a penalty that started at 1% on 18 September 2025 and is programmed to increase by an additional 1% every three months. This mechanism is hard-coded into the upgrade smart contracts, meaning the penalty escalates automatically without requiring a new governance vote for each increase. Its primary function is to protect the new ecosystem by reducing the outstanding supply of the old governance token.
What this means: This is neutral for SKY because it's a planned enforcement of existing rules, not a new feature. It systematically reduces the potential overhang of unconverted tokens, which could help stabilize the governance process in the long term by ensuring all active participants are using the same token.

2. Migration Go-Live & Spell Execution (19 May 2025)
Overview: This was the mainnet deployment of the upgrade, where the approved "spell" (a bundle of smart contract changes) was executed. It permanently replaced MKR with SKY as the protocol's governance token.
Executing this spell involved multiple smart contract interactions: deactivating old MKR token functions, activating the new SKY token contract, and updating all core protocol modules (like the Staking Engine and governance vaults) to recognize SKY. This was a irreversible, breaking change to the protocol's core logic, requiring precise coordination with exchanges and integrators.
What this means: This was bullish for SKY because it successfully activated the new tokenomics and governance model. It gave holders direct access to staking rewards and solidified SKY's role as the sole key to governing one of DeFi's largest ecosystems.

3. Governance Poll and Spell Publication (12–15 May 2025)
Overview: This phase involved the community voting on the final upgrade proposal and then auditing the published code. It was the final check before the irreversible launch.
The governance poll allowed MKR holders to signal approval for the upgrade plan. Once passed, the technical team published the exact spell code for a 72-hour review period, allowing developers and security experts to inspect the changes for errors. This process is critical for decentralized governance, ensuring transparency and collective agreement before any live deployment.
What this means: This was bullish for SKY because it demonstrated a robust, community-driven upgrade process. The successful vote and public audit built trust in the new system's security and legitimacy before it went live.

Conclusion
Sky's codebase has matured through a major, successfully executed upgrade, shifting focus from deployment to enforcing its new rules. The current phase is algorithmically managing the token transition, emphasizing protocol stability and full user migration.
How will the completion of the penalty ramp-up and the full retirement of MKR impact SKY's governance concentration and long-term value accrual?
