Deep Dive
1. Prover Stack Upgrade to OpenVM v2.0 (22 September 2026)
Overview: This update improves the core system that secures the Scroll network. For users, it means stronger security and a more advanced foundation, though regular transactions were unaffected.
The upgrade moved the prover stack from OpenVM v1.6 to v2.0. The key technical change is the integration of the SWIRL proof system, which is used to generate the zero-knowledge proofs that verify Scroll's transactions on Ethereum. The update also included the latest security fixes. The upgrade occurred on 22 September 2026 at 02:00 UTC, causing a planned one-hour delay in batch finalization, while deposits and L2 execution continued normally.
What this means: This is neutral to bullish for $SCR because it strengthens the network's underlying security and keeps its technology stack current. Users benefit from a more robust and modern system, though the immediate impact on everyday experience is minimal.

2. Bernoulli Hard Fork & Bridge Optimizations (April 2024)
Overview: This was a major network upgrade designed to make using Scroll much cheaper by optimizing how transaction data is stored and processed.
The Bernoulli upgrade was a hard fork implemented in April 2024. Its central feature was support for EIP-4844 "data blobs," a more cost-efficient way to post data to Ethereum. A concurrent bridge upgrade merged contracts and used constants instead of storage variables to reduce gas costs for bridging assets. Node operators were required to upgrade to version v5.3.0 before the hard fork.
What this means: This was extremely bullish for $SCR because it directly addressed one of the biggest user pain points: high costs. The update made transactions and bridging substantially cheaper, improving Scroll's competitiveness as a scaling solution.

3. Rainbow Wallet Integration (21 November 2025)
Overview: While not a codebase change to Scroll's core protocol, the integration of a major wallet like Rainbow signals healthy ecosystem development and improves accessibility for new users.
The popular Rainbow wallet announced native support for the Scroll network. This allows users to manage Scroll-based assets and interact with dApps directly through a familiar interface without manual configuration.
What this means: This is bullish for $SCR because it reduces friction for adoption. Easier access through trusted wallets can attract more users and developers to the ecosystem, driving network activity and utility.
