Deep Dive
1. Chain Merger & Sunset (Early 2026)
Overview: Immutable completed a major architectural update by merging its legacy Immutable X network with the newer Immutable zkEVM into a single, unified Immutable Chain. This sunset the original Immutable X, with automated asset migration finishing in March 2026.
This was a foundational codebase change that retired the StarkEx-based Layer 2 in favor of the EVM-compatible zkEVM chain. The new Immutable Chain offers developers a consistent environment with two-second block times, gas sponsorship, and uses IMX as its native currency for fees, staking, and governance. The merger eliminates complexity, requiring all ecosystem activity and future development to occur on the single chain.
What this means: This is bullish for IMX because it simplifies the experience for both game developers and players, reducing friction and concentrating all network activity and fee generation on one platform. A unified chain makes building and using games smoother and could drive more consistent demand for the IMX token.

2. Biweekly Staking Model (19 June 2025)
Overview: The protocol updated its staking mechanics, shifting from weekly to biweekly reward distributions and tying rewards directly to 2% of the fee-generated revenue from NFT transactions on the platform.
This codebase update changed the economic incentives within the ecosystem. Staking is now exclusively on the zkEVM chain (now Immutable Chain), and rewards are calculated based on real platform usage and volume. This creates a direct feedback loop: more user activity generates more fees, which increases staking rewards.
What this means: This is neutral-to-bullish for IMX because it aligns long-term tokenholder rewards with the actual growth and usage of the Immutable ecosystem. It incentivizes holding and participation, but the value of rewards depends entirely on the platform's transaction volume.

Conclusion
Immutable's recent codebase evolution focuses on consolidation and sustainable incentive alignment, moving from a dual-chain model to a unified platform with usage-based staking. This technical streamlining aims to reduce developer friction and tie token value closer to ecosystem growth. Will the simplified infrastructure be enough to catalyze the next wave of breakout games on the chain?
