Starknet v0.14.3 Goes Live With Dynamic Fees, 1.5s Blocks

High attention and emotional sentiment detected.

StarkWare, the core developer behind Starknet, framed the release as a performance and infrastructure upgrade. So the changes target fee stability, latency, and prover capabilities rather than flashy consumer features.

What Starknet v0.14.3 Changes

The upgrade rests on three headline changes. First, a dynamic base fee now adjusts with the STRK price. Second, block times drop from about two seconds to 1.5 seconds. Third, the prover and verifier gain new tools for privacy-related flows.

Testnet users saw these changes earlier. Starknet shipped the upgrade to testnet on June 22, well before the mainnet activation. According to the team, the mainnet switch required up to roughly eight minutes of downtime.

This release continues a steady cadence of upgrades. Earlier, v0.14.0 introduced decentralized sequencing and cut block times from roughly 30 seconds to about 6 seconds. Since then, StarkWare has layered in fee, latency, and privacy work with each point release.

Dynamic Gas Fees Tied to STRK Price

The dynamic base fee comes from SNIP-35. Previously, the sequencer set a mostly static minimum fee in STRK terms. As a result, real costs swung whenever the STRK price moved.

Now an algorithm adjusts the minimum base fee automatically. It reads the STRK price and congestion signals, then targets stable costs in real-world value. In other words, users should pay a steadier amount in dollar terms even when STRK is volatile.

STRK traded around $0.03 at launch. So predictable pricing matters more when a token sits at low nominal values.

Builders benefit too. Predictable fees make it easier to price transactions inside apps, so wallets and dApps can set clearer expectations for users.

Faster 1.5-Second Blocks

The faster blocks come from SNIP-40. Block times fall from about two seconds to 1.5 seconds, a 25% cut. For users, that means quicker confirmations and lower latency in apps.

The change also retunes block capacity. Target L2 gas per block drops 30%, from 1.5 billion to 1.04 billion, while the maximum block size stays the same. To balance that, StarkWare raised the gas costs for storage reads and writes.

Privacy Proving and a Quantum-Resistant Hash

The third pillar strengthens the prover and verifier. SNIP-36 adds Keccak support in the verifier for virtual OS blocks and client-side proving. In turn, that enables virtual private transactions signed with Ethereum-style signatures.

The Keccak builtin matters for compatibility. Because Ethereum relies on Keccak, the addition lets Starknet verify EVM-style signatures inside its proofs. As a result, developers can build privacy flows that feel familiar to Ethereum users.

Still, this is enabling infrastructure, not a live privacy feature for everyday users. The upgrade lays groundwork for shielded flows rather than switching them on today.

The release also changes the SNOS program and config hashes from Pedersen to BLAKE. StarkWare describes the switch as a quantum-resistance hardening step. According to the team, BLAKE better positions the network for post-quantum security.

These moves fit what StarkWare calls its Privacy Arc. That roadmap positions Starknet as a ZK execution layer with privacy and quantum-secure ambitions.

Breaking Changes Developers Should Watch

The upgrade also ships breaking changes. It deprecates RPC 0.8, changes the SNOS hash, and shifts gas costs. Because of that, some builders will need to migrate tooling and update their integrations.

Starknet Foundation governance approved v0.14.3 before the rollout. So the changes arrived through the network’s on-chain process rather than a unilateral push.

Muted Market Reaction and Governance Pushback

Meanwhile, the market barely moved on the news. STRK traded near $0.03 on July 8, down roughly 2% to 5% intraday, with no clear upgrade rally. Its market cap sat around $200 million, according to CoinGecko and CoinMarketCap data.

Trading volume stayed thin as well. STRK saw roughly $13 million to $18 million in 24-hour volume, according to market trackers. So the reaction looked muted rather than bearish.

Total value locked on Starknet held near $172 million, according to DefiLlama. So the upgrade looked routine to traders, even as it reshaped the network’s fee and latency profile.

Not everyone is fully sold on the fee design. Analysts at L2BEAT flagged a governance concern about SNIP-35, warning that fee revenue flows to sequencers and could drift without stronger constraints. Some developers also noted migration friction.

What Comes Next for Starknet

Starknet v0.14.3 sets the stage for the network’s next phase. Faster blocks and steadier fees improve the day-to-day experience, while the prover upgrades point toward private, quantum-resistant flows.

Still, the bigger questions remain open. StarkWare has not committed to a firm timeline for production private transactions, and the long-term effect on adoption is unproven. For now, builders can test the new gas costs, then watch how the dynamic fee performs in real conditions.
