Starknet Launches Shinobi Upgrade for Native Privacy, STRK Price Rises

Starknet’s Shinobi upgrade brings native privacy to its mainnet. STRK price rose nearly 7% as STRK20 and strkBTC integrations near launch.

Starknet has activated its Shinobi upgrade on mainnet. 

The release, formally known as Starknet v0.14.2, introduces native privacy infrastructure to the network. It marks a significant shift in how the Layer 2 blockchain handles transaction verification. 

According to the official announcement, the upgrade transforms Starknet from a high-performance rollup into a privacy-preserving engine. STRK, the network’s native token, responded with a notable price increase following the news.

What the Starknet Shinobi Upgrade Actually Does

The technical core of the Shinobi upgrade is in-protocol proof verification, defined under SNIP-36. 

Before this update, verifying a STARK proof inside a smart contract was not practical. STARK proofs contain tens of thousands of field elements. That made them far larger than the maximum transaction size the network permitted.

Developers previously had no choice but to split proofs across multiple transactions. That approach was slow, complicated, and costly. The Shinobi upgrade removes that barrier entirely.

Starknet’s v0.14.2 release allows transactions to reference off-chain execution proofs directly. New proof and proof_facts fields in the Invoke V3 transaction structure make this possible. The network’s consensus layer now handles verification natively. 

In practice, users can prove a transaction is valid without revealing their full balance or transaction history to the public network.

The upgrade also includes economic adjustments under SNIP-37. Storage costs increase while base L2 gas prices drop. This rebalancing aims to ensure that applications with heavy state usage pay proportionally more, while average users benefit from lower fees.

STRK20 and strkBTC: Privacy Assets Coming to Starknet

The Shinobi upgrade sets the foundation for two major projects. STRK20 is a new framework that allows any ERC-20 token on Starknet to operate with private balances. 

From day one, users will be able to swap, stake, and transfer ERC-20 tokens while keeping their financial activity shielded. More DeFi integrations are expected to follow.

strkBTC targets Bitcoin holders directly. The upgrade enables private Bitcoin interactions within the Starknet ecosystem. Users will be able to access DeFi applications without exposing their full Bitcoin wallet history on a public ledger. 

According to the announcement, Bitcoin holders will have access to hard money that is both private and productive through Starknet’s BTCFi offerings.

Both projects carry a compliance note. A third-party audit firm will hold a viewing key. That firm may share individual user transactions and transaction history in response to valid legal or regulatory requests.

Beyond privacy, the upgrade lays groundwork for zkThreads, described as a key primitive on Starknet’s path toward infinite scaling. 

Technical updates to StarkGate token contracts under SNIP-13 also align ERC-20 events with industry standards. These changes prepare the network for its upcoming decentralized validation phase.

STRK Price Jumps as Market Reacts to Privacy News

The STRK token reacted positively after the Shinobi upgrade went live. 

According to CoinGecko data, STRK was trading at $0.03731 at the time of reporting. That reflects a 6.97% gain over the prior 24 hours. The token also posted an 11.88% increase over the past seven days.

Trading volume rose sharply alongside the price. 

The 24-hour volume reached $24,768,604, up 76.70% from the previous day. That spike signals a clear rise in market activity tied to the upgrade announcement.

Over the past week, STRK traded between $0.03215 and $0.03774. The daily range at the time of reporting sat between $0.03486 and $0.0376. 

The token’s upward move coincides with growing anticipation around STRK20 and strkBTC, both of which the team says will launch in the coming weeks.

Starknet positions the Shinobi upgrade as a turning point. The network now carries the infrastructure needed to support private transactions at the protocol level.
