Aligned Engineering Updates: November, 2025

Aligned Layer

02 Dec 2025 — 2 min read

During November we ran the zk-arcade campaign, and delivered 33 PRs across both repositories that expanded platform capabilities and improved stability.

Major highlights:

Ethereum Fusaka Fork migration: Migrated Aligned to support Ethereum's Fusaka upgrade with EIP-7594 blob sidecars
Mina verifier integration: Added support for Mina proof systems, expanding our verification capabilities in testnet. Notice this is also not a full bridge.
Public NFT system: Implemented end-to-end public NFT functionality including smart contracts, minting metrics, and frontend support
Enhanced UX: Added calendar functionality, gas-based time estimations, and comprehensive UI improvements to support the campaign
Platform stability: Deployed enhanced telemetry, resolved critical bugs affecting users, and improved batching processes

Through the month, we balanced new feature development with platform stability, ensuring a smooth campaign experience while laying groundwork for expanding our products.
