Starknet has achieved full post-quantum security across its infrastructure, marking a significant milestone in blockchain resilience against future quantum computing threats.​

Key Developments:

• Post-quantum proving system - Already implemented by design in Starknet's core architecture
• Post-quantum wallets - Now live on the network with seamless migration path
• Native Account Abstraction - Enables easy transition without requiring address changes or hard forks

The upgrade required no disruptive network changes, allowing users to maintain their existing addresses while gaining quantum-resistant security.​ Most of the technical implementation work has been completed, positioning Starknet as one of the first major blockchain networks to achieve comprehensive post-quantum readiness.​

This development addresses growing concerns about quantum computers potentially breaking current cryptographic standards used in blockchain technology.​

Contango published a detailed analysis of its V2 platform's user churn, comparing retention metrics across DeFi protocols including Fluid, Lazy Summer Protocol, DeFi Saver, Infinex, and Defi.​app.​

Key findings:

• Contango V2 achieved $584M peak open interest and became the second-largest leverage trading app after Hyperliquid
• User churn increased in late 2025 as free looping widgets emerged on lending markets and yield opportunities fragmented across chains
• Correlation between Contango volumes and overall DEX activity dropped from 70% to 14% between July and December 2025

Competitor insights:

• Fluid showed strongest retention with near-zero churn, keeping capital productive while used as collateral
• Lazy Summer Protocol experienced consistent turnover, particularly around token launch anticipation
• DeFi Saver demonstrated that automation creates retention even when manual activity drops
• Infinex and Defi.​app showed artificial retention through withdrawal restrictions and token lock bonuses

V3 strategy lessons:

• Points programs buy time, not loyalty
• Power users value set-and-forget automation
• Idle capital represents flight risk

Contango V3 aims to address these challenges with progressive release planned for coming weeks.​

Venus Protocol is preparing to launch a new feature that will bring fixed yield opportunities to its platform through integration with Pendle Finance.​

Key details:

• One-click access to fixed yields
• No prior Pendle experience required - simplified user experience
• Launch timeline not yet announced

This integration aims to make fixed-rate DeFi yields more accessible to Venus users by removing the complexity typically associated with Pendle's yield tokenization protocol.​
