October 23, 2025 – Sonic Labs, the high-performance EVM Layer-1 blockchain, has issued an urgent directive for all mainnet and testnet nodes to upgrade to version 2.1.2 immediately. The update introduces native fee subsidies, essential security enhancements, and key features supporting the upcoming Pectra transition on November 3, 2025, at 15:00 CET.
Sonic Labs builds upon its Fantom legacy, evolving from the DAG-based consensus model that once achieved 10,000 TPS to today’s 400,000 TPS performance. The Sonic testnet introduced the FeeM model in 2024, rebating 90% of transaction fees to developers—a system that continues to define its ecosystem economics.
Earlier milestones, such as the August 2025 Testnet 2.1 integrating Ethereum’s Pectra features, laid the groundwork for broader interoperability. The Sonic 2.1.2 upgrade refines these advances by addressing security vulnerabilities and preparing the network for higher throughput as institutional tokenization and real-world asset adoption accelerate.
The Sonic 2.1.2 upgrade represents a pivotal step in establishing Sonic as a leading EVM-compatible settlement layer for global finance. With account abstraction and improved blob capacity, Pectra readiness is expected to reduce gas costs by up to 30%, enhance scalability, and support gasless transactions.
Market reaction has been swift, with $S trading 2% higher at $0.92 and 15% volume surges amid node operator compliance. Analysts anticipate a 10–20% post-Pectra rally driven by the Innovator Fund and ETF initiatives, reinforcing confidence in Sonic’s roadmap and the long-term potential of the Sonic 2.1.2 upgrade.
Sonic Labs’ urgent upgrade to version 2.1.2, announced October 23, 2025, cements its position as a high-performance EVM Layer-1 blockchain, building on Fantom’s 400,000 TPS legacy. With native fee subsidies and Pectra readiness, Sonic enhances developer economics and institutional-grade scalability, positioning it to capture growing DeFi and RWA liquidity in a $1T EVM market.
