Deep Dive
1. Mainnet Pectra Compatibility (3 November 2025)
Overview:
Sonic mandated a network-wide node upgrade to v2.1.2, introducing native fee subsidies for developers and critical security patches.
This upgrade ensures compatibility with Ethereum’s Pectra upgrade, enhancing cross-chain interoperability. Node operators faced disconnection risks if they missed the 3 November 2025 deadline, impacting validator rewards and RPC functionality.
What this means:
This is bullish for Sonic because it strengthens network security while incentivizing developer activity through fee subsidies. Users benefit from smoother cross-chain interactions.

2. Testnet 2.1 Launch (12 August 2025)
Overview:
Testnet 2.1 added support for Ethereum’s Pectra upgrade, enabling developers to test advanced EVM features like account abstraction and gas optimizations.
The update leveraged SonicVM for improved scalability, claiming 10x faster node synchronization and reduced validator costs.
What this means:
This is neutral for Sonic as it primarily prepares the groundwork for future mainnet enhancements. Developers gain tools to build more efficient dApps, potentially boosting long-term adoption.

3. Covalent Integration (8 October 2025)
Overview:
Covalent’s integration provided real-time on-chain data access, replacing manual indexing with sub-second query speeds for EVM and non-EVM chains.
Developers can now fetch transactional data without RPC bottlenecks, streamlining app development.
What this means:
This is bullish for Sonic because it reduces friction for builders, accelerating dApp deployment and improving user experiences with faster, reliable data.

Conclusion
Sonic’s recent codebase updates emphasize scalability (Pectra compatibility), developer incentives (fee subsidies), and infrastructure robustness (Covalent integration). These changes align with its goal to become a high-speed hub for institutional and retail adoption.
How might these upgrades position Sonic against competing EVM chains in 2026?
