Optimism has revealed an ambitious plan to strengthen the security of its ecosystem in the long term. The strategy aims for a deep modernization that prepares the network for future cryptographic challenges, synchronized across its entire Superchain infrastructure.

From ECDSA to Smart Contracts: The Fundamental Shift

The core of this transformation involves gradually phasing out external accounts (EOA) that currently use the ECDSA algorithm on the main OP network and the Superchain. According to Foresight News, users will need to transfer the management of their private keys to specialized post-quantum smart contracts. This change represents a significant leap in security architecture, protecting wallets against future computational threats.

Unified Synchronization Across the Entire OP Stack Network

The proposal includes gradually eliminating transactions based on original ECDSA signatures once the transition phase is complete. The different chains that make up the OP Stack will remain synchronized according to a coordinated roadmap, ensuring that all security updates are implemented harmoniously across the Superchain network. This centralized coordination prevents fragmentation and guarantees a consistent experience.

A Ten-Year Timeline for Complete Migration

Subject to community governance approval, this process will extend over ten years. The schedule allows users and developers to adapt gradually, without abrupt disruptions to the network’s operation. The transition is designed to be orderly and predictable, providing enough time for all stakeholders to migrate their systems in sync with the new post-quantum standard.
