Astar Runtime 1700 Upgrade: Enhanced Emergency Response & Infrastructure Improvements
Introduction
Greetings, Astar Community! 
We are excited to share a significant runtime upgrade coming to Astar Network that introduces critical governance and security enhancements designed to strengthen our emergency response capabilities while maintaining the decentralized principles that define our ecosystem. Runtime 1700 represents a crucial evolution in our network infrastructure, providing our Technical Committee and Main Council with sophisticated tools to respond swiftly to security incidents without compromising democratic governance.
This upgrade addresses lessons learned from recent ecosystem events, particularly the need for rapid response mechanisms during critical security situations. The new emergency response tools will enable precise, targeted interventions while preserving user rights and maintaining transparency. Additionally, this release includes important infrastructure improvements that prepare Astar for upcoming Polkadot ecosystem developments.
Emergency Response Enhancements
1. dApp Staking Maintenance Mode – Governance Trigger 
Building upon the existing maintenance mode functionality, this enhancement significantly improves how we can activate emergency protocols during dApp staking security incidents. Previously, maintenance mode activation required lengthy referendum processes that could prove insufficient during time-critical situations.
Key References:
Key Updates:
Enhanced Activation Authority: Maintenance mode can now be triggered by either two-thirds of the Main Council (4 out of 6 members) or one-half of the Technical Committee (2 out of 3 members), eliminating the need for referendum processes during emergencies.
Immediate Protocol Protection: When activated, maintenance mode instantly halts all dApp staking interactions, preventing new staking operations, unstaking requests, and reward claims while simultaneously pausing era advancement to prevent further storage modifications.
Rapid Response Capability: This enhancement addresses scenarios where protocol compromise is detected and immediate action is required to protect user funds and network integrity, as demonstrated during the Neemo Finance incident where rapid response was critical.
2. TxPause Functionality 
This represents entirely new functionality that provides surgical precision in emergency responses, allowing governance to selectively pause individual extrinsics without disrupting the entire network operation. TxPause functionality offers unprecedented flexibility in addressing security vulnerabilities.

Key Updates:
Granular Control Mechanisms: TxPause enables targeting specific pallets and functions rather than broad system shutdowns. For example, governance can pause only the claimUnlocked function within dApp staking while maintaining all other staking operations, or disable specific balance transfer types while preserving essential network functions.
Flexible Activation Thresholds: Similar to maintenance mode, TxPause can be activated by either two-thirds of the Main Council or one-half of the Technical Committee, ensuring rapid deployment when security threats are identified.
Minimal Network Disruption: This functionality allows for precise interventions that address specific vulnerabilities while keeping the majority of network operations running normally, reducing impact on users and developers during security incidents.
3. Safe Mode Implementation 
Safe Mode represents the most comprehensive emergency measure available to Astar governance, designed for use during critical vulnerabilities or chain-threatening errors. This functionality provides the strongest possible response to existential network threats while maintaining essential system operations.
Key References:
Key Updates:
Comprehensive Transaction Blocking: When activated, Safe Mode blocks nearly all user-submitted transactions including dApp staking operations, balance transfers, Ethereum transactions, proxy calls, and most user interactions while allowing only essential system operations such as governance actions, parachain lifecycle functions, and timestamping.
Configurable Duration Controls: Safe Mode initializes with a 12-hour active period that can be extended in 2-hour increments as needed, providing flexibility to address extended security situations while preventing indefinite emergency states.
Chain-Critical Response: This functionality is specifically designed for use during active exploit windows or when critical vulnerabilities threaten the entire network, providing governance with the tools necessary to prevent catastrophic damage while solutions are implemented.
Infrastructure & Runtime Improvements
4. Asset Hub Integration in Token Reserve Filter 
This upgrade introduces Asset Hub as a recognized relay chain reserve location, positioning Astar Network for seamless integration with upcoming Polkadot and Kusama Asset Hub migrations. This enhancement ensures Astar remains compatible with evolving Polkadot ecosystem infrastructure.
Key References:

Key Updates:
Future-Proof Integration: Asset Hub recognition prepares Astar for upcoming ecosystem changes while maintaining backward compatibility with existing asset management systems.
Enhanced Interoperability: This integration strengthens Astar’s position within the broader Polkadot ecosystem by ensuring seamless asset transfers and cross-chain functionality as the network evolves.
5. Collator Selection Improvements 
Runtime 1700 introduces enhanced collator management capabilities that provide more granular control over network validation while improving overall performance tracking and benchmarking accuracy.
Key References:
- Collator selection enhancements PR #1502
- Updated weight calculations PR #1508
Key Updates:
Granular Collator Management: New extrinsics enable adding and removing individual invulnerable collators, providing more precise control over network validation infrastructure.
Performance Optimization: Updated weight calculations improve performance tracking and benchmarking accuracy, contributing to more efficient network operations and better resource allocation.
