Starknet's Grinta upgrade, intended to enhance performance and decentralization, experienced a multi-hour outage and chain reorganization, leading to a 4.5% drop in the STRK token's price.

The Grinta Upgrade: Features and Implementation

The Starknet v0.14.0, codenamed Grinta, was launched on Mainnet on August 18, 2025, introducing several significant enhancements aimed at advancing the network's capabilities and decentralization. Key features included a decentralized sequencer architecture, marking the initial step toward a fully decentralized sequencing model on Starknet with three sequencers operating under Tendermint consensus. The upgrade also introduced pre-confirmations, an intermediate transaction status with approximately 0.5 seconds latency, designed to make most transactions feel near-instant. Furthermore, Grinta implemented a new fee market for L2 gas, inspired by Ethereum’s EIP-1559, which incorporates a system of base fees and tips. With this update, the network exclusively supports v3 transactions, utilizing STRK for gas fees, and an upgraded mempool prioritizes transactions based on tip amount, replacing the previous First-In, First-Out (FIFO) system.

Post-Launch Instability and Network Reorganization

Immediately following its deployment, the Starknet network experienced a multi-hour outage on September 2, 2025, halting block production between 02:23 and 04:36 UTC. This incident, attributed to an ungraceful recovery from P2P issues on the Ethereum network and sequencer failure during the transition to Cairo1 code, necessitated a chain reorganization from block 1,960,612. As a consequence, transactions submitted during the outage window were invalidated, requiring users and decentralized applications (dApps) to resubmit them. Developers acknowledged the turbulence, drawing comparisons to similar outages experienced by other networks like Solana, while emphasizing the ongoing progress in uncharted ZK rollup design and the project's long-term decentralization objectives.

Financial Impact and Market Response

The outage had a direct financial impact on the STRK token, which saw its price drop approximately 4.5% to $0.1204 during the disruption. The introduction of STRK as the exclusive token for gas fees within the new EIP-1559-like fee market integrates the token more deeply into the network's economic mechanics. Despite the short-term price volatility and operational challenges, Starknet's Total Value Locked (TVL) stands at $548 million, positioning it among other Layer 2 solutions that face similar pressures to balance innovation with stability.
