VeChain is preparing for one of the most significant technical upgrades in the history of the VeChainThor blockchain after confirming that its Interstellar network upgrade is expected to take place on September 16, 2026.
The upgrade, implemented through VIP-255, packages 11 Ethereum Improvement Proposals into a single protocol update. According to VeChain, Interstellar is expected to activate at block height 25,902,540, with the projected activation time set for 11:15:10 UTC on September 16, although the exact timing may vary depending on block production.
The development follows the successful stakeholder vote on the proposal and marks the third major stage of VeChain’s broader Renaissance roadmap. While the upgrade contains several deeply technical changes, its broader objective is straightforward: bring VeChainThor closer to Ethereum’s EVM standards, improve interoperability, and make the network easier for developers, enterprises, and applications to use.
For $VET holders, the importance of Interstellar may ultimately depend less on the individual EIPs and more on what they enable. The upgrade is designed to reduce friction for Ethereum-compatible applications, introduce new cryptographic capabilities, improve transaction efficiency, and prepare VeChainThor for a wider range of DeFi, enterprise, AI and cross-chain use cases.
Interstellar Brings VeChainThor Closer to Ethereum
One of the central themes behind VIP-255 is EVM compatibility.
Ethereum remains the dominant smart contract ecosystem, meaning many blockchain developers, tools and applications are built around Ethereum standards. Networks that closely follow EVM developments can make it easier for developers to move applications between ecosystems without having to redesign major parts of their code.
VeChain says Interstellar closes part of the technical gap between VeChainThor and newer Ethereum upgrades, incorporating improvements associated with Ethereum’s Cancun, Prague and Osaka development paths.
The update introduces EIP-1153, which adds transient storage. This gives smart contracts temporary storage that can be used during execution without permanently writing the data to the blockchain. The result could be lower costs for certain complex smart contract operations.
EIP-5656, known as MCOPY, introduces a more efficient method for copying data in smart contract memory. Although this may sound like a minor technical improvement, such optimizations can reduce computational costs for applications that handle large amounts of data.

Another important change is EIP-6780, which modifies how the SELFDESTRUCT operation works. The update aligns VeChainThor more closely with Ethereum’s evolving approach to contract lifecycle management, potentially making smart contracts easier to audit and analyze using existing Ethereum-focused tools.
The Interstellar package also includes EIP-7939, which introduces a new instruction for counting leading zeros. This is particularly relevant for mathematical operations and could improve efficiency in areas such as fixed-point calculations, compression and zero-knowledge technology.
Taken together, these changes are intended to make VeChainThor a more familiar environment for developers already building within the Ethereum ecosystem.
Passkeys, Cryptography and Enterprise Applications Could Be Major Winners
Some of the most important features of Interstellar extend beyond simple EVM compatibility.
EIP-7951 introduces support for the secp256r1, or P-256, cryptographic curve. This technology is already widely used across modern smartphones, laptops, hardware security systems and passkey infrastructure.
Its addition could help VeChain move closer to a future where blockchain users do not necessarily need to manage traditional seed phrases in order to interact with applications.
Instead, users could potentially authorize blockchain activity using familiar authentication systems such as fingerprints, facial recognition and device-based security credentials.
This could be particularly significant for VeChain’s enterprise ambitions.
Businesses are unlikely to onboard large numbers of employees or customers into blockchain applications if every user must understand private keys and seed phrases. The ability to integrate authentication methods already used in corporate and consumer environments could lower that barrier.
Another major component is EIP-2537, which adds support for the BLS12-381 cryptographic curve.
This technology is relevant to signature aggregation and zero-knowledge proofs, two areas with growing importance across blockchain infrastructure. Zero-knowledge technology allows information to be verified without necessarily revealing the underlying data.
For VeChain, this could have practical applications in supply chain management, sustainability reporting and enterprise data verification.
A company could potentially prove that it meets a particular standard without placing commercially sensitive information directly on a public blockchain. That concept fits closely with VeChain’s existing focus on enterprise and real-world applications.
The upgrade also includes changes to modular exponentiation through EIPs 7823 and 7883, improving the pricing and limits of computationally expensive operations.
These improvements may not attract the same attention as new consumer-facing features, but they are important for network stability and future scalability.
Interstellar Prepares VeChain for Higher Capacity
VIP-255 also introduces changes designed to make VeChainThor more predictable and resilient as activity increases.
EIP-7825 introduces a cap on the amount of gas that can be consumed by a single transaction. This prevents individual transactions from consuming an excessive share of network resources.
That is particularly relevant for VeChainThor because the network supports multi-clause transactions, allowing multiple actions to be bundled together.
The upgrade also implements EIP-7934, which establishes an 8 MiB block size limit.
Limiting block size can help prevent excessive blockchain growth and reduce the hardware requirements for running nodes. Maintaining manageable node requirements is important for decentralization because networks become more difficult to validate if participation requires increasingly expensive infrastructure.
Meanwhile, EIP-2935 improves access to historical block information using a standard interface familiar to Ethereum developers. This could make it easier for proof systems and light-client designs built for Ethereum to work with VeChainThor.
Together, these changes are designed to improve the foundation on which future scaling efforts can be built.
The significance of Interstellar, therefore, is not simply that VeChain is adding 11 new technical features. The broader objective is to create a blockchain that can support a growing range of applications without forcing developers and users to adapt to an entirely separate technological environment.
What the Interstellar Upgrade Could Mean for $VET
The upcoming upgrade does not automatically guarantee a price increase for $VET.
Network upgrades and token prices are influenced by different factors, including broader cryptocurrency market conditions, liquidity, investor sentiment, adoption and actual network usage.
However, major protocol upgrades can strengthen the long-term investment case for a blockchain if they result in increased developer activity and real-world demand.
For VeChain, the key question following Interstellar will be whether improved EVM compatibility translates into more applications being deployed on VeChainThor.
The introduction of passkey-compatible authentication could also make the network more accessible to mainstream users, while zero-knowledge capabilities may strengthen VeChain’s position in enterprise and sustainability-focused blockchain applications.

Lower-cost smart contract operations and improved developer compatibility could further support new DeFi applications.
VeChain has spent years positioning itself differently from many blockchain networks by focusing heavily on enterprise adoption, supply chains and sustainability. Interstellar could expand that strategy rather than replace it.
By becoming more compatible with the broader Ethereum ecosystem, VeChain may be able to connect its existing business and sustainability infrastructure with a much larger pool of blockchain developers and applications.
That could ultimately prove more important than any individual EIP included in VIP-255.
VeChain’s Next Major Test Begins After September 16
The Interstellar upgrade represents another major step in VeChain’s Renaissance roadmap.
Following stakeholder approval, the focus now shifts from governance to implementation. If the activation proceeds as expected, September 16 could mark the beginning of a new technical phase for VeChainThor.
The upgrade brings 11 Ethereum improvement proposals into the network, covering smart contract efficiency, cryptography, authentication, transaction limits, block size and developer compatibility.
For users, some of these improvements may eventually become visible through cheaper transactions, easier wallet experiences and new applications. For developers, the changes could reduce friction when bringing Ethereum-compatible tools and smart contracts to VeChainThor.
For enterprises, features such as passkey support and advanced cryptographic verification could open new possibilities for blockchain systems that require both transparency and privacy.
The market will still judge the upgrade by its results.
Interstellar can improve VeChain’s technical foundation, but adoption will determine whether those capabilities translate into greater network activity and long-term demand for the ecosystem.
For now, September 16 is the date VeChain users, developers and $VET investors will be watching as the network prepares to enter the next stage of its Renaissance.
