Ethereum researchers are using artificial intelligence to investigate whether the upcoming Glamsterdam upgrade could affect existing smart contracts unexpectedly. Their work has identified potential risks across 13 contracts, contributing to the decision to postpone a planned test on the Hoodi test network.
The delay does not necessarily mean Glamsterdam has failed or that Ethereum is under immediate threat. It reflects the careful testing process required for changes that could influence applications holding valuable user assets. Here is what the postponement means and what Ethereum users should watch next.
What is the Ethereum Glamsterdam upgrade?
Glamsterdam is a proposed Ethereum network upgrade designed to improve performance, scalability, and network efficiency. Upgrades of this kind can modify how transactions are processed, how the network stores data, or how validators coordinate their work.
Think of Ethereum as a large apartment building with interconnected electrical, plumbing, and security systems. A small software update may appear harmless from the outside, but it can trigger unexpected behavior in equipment installed years ago. Smart contracts are similar: they were built for specific network rules and may react differently when those rules change.
Why was the Glamsterdam test postponed?
The planned test on Hoodi was delayed after researchers detected potential problems affecting 13 existing contracts. Hoodi is Ethereumβs dedicated test network, where developers and validators can test proposed upgrades without putting real funds at risk.
Postponing a test is a normal safety measure. It gives researchers more time to reproduce the issue, compare the affected code with the proposed network rules, and determine whether changes are needed before the upgrade reaches the main Ethereum network.
Importantly, the published findings do not establish that all 13 contracts are unsafe or permanently broken. They identify areas where the upgrade may produce unexpected consequences. Each finding must be analyzed to distinguish a genuine incompatibility from behavior that developers already anticipate.
How AI is helping researchers identify contract risks
The research team is now using AI agents to examine interactions between the proposed upgrade and contracts already deployed on Ethereum. AI agents are automated software systems that can perform defined tasks, such as scanning code, generating test scenarios, and comparing expected and observed behavior.
This approach could help researchers examine more contract combinations than manual review alone. It can also highlight unusual code paths that human testers may overlook. However, AI should be treated as an investigative assistant rather than an automatic verdict.
An AI system may produce false positives, miss subtle problems, or misunderstand the intended behavior of a protocol. Its findings therefore need to be verified by experienced developers and security researchers. The technology expands the testing toolkit, but it does not replace expert judgment.
Why smart contract compatibility matters
Smart contracts are programs that automatically manage assets and transactions when specific conditions are met. Once deployed, some contracts are effectively immutable, meaning their code cannot simply be edited. If a network upgrade changes the environment in which they operate, even a small difference can matter.
Potential consequences include failed transactions, altered gas costs, disrupted liquidation mechanisms, or changes in how functions behave under congestion. These issues can affect decentralized finance, decentralized autonomous organizations, token systems, bridges, and other applications.
For DeFi users, compatibility testing is particularly important because protocols often coordinate with wallets, stablecoins, lending markets, and oracle services. A problem at the network level can create ripple effects across several connected applications, much like a traffic closure affecting multiple roads.
What does this mean for ETH holders?
The postponement is primarily a development and security issue, not a direct signal to buy or sell ETH. The network upgrade is intended to improve Ethereum over time, but delays may push back expected performance or ecosystem benefits. They may also increase development and testing costs.
Users should monitor official Ethereum developer discussions, client releases, and the revised Hoodi test schedule. Those are the most reliable sources for confirmed information. Social media claims about specific failures should be treated cautiously until developers publish reproducible results.
What Ethereum developers will likely do next
The next phase is expected to involve deeper testing of the 13 affected contracts and possible modification of the upgrade itself. Developers may also update the client software, publish detailed analysis of the findings, and announce a new Hoodi activation window.
Researchers will need to verify whether the problematic behavior originates in the upgrade, in outdated contract assumptions, or in a dependency outside Ethereumβs core system. The final solution could involve adjusting the network proposal, changing contract integrations, or documenting that certain applications require updates.
How users can protect themselves during the delay
No immediate action is required from ordinary Ethereum users based solely on the reported findings. Still, security-conscious participants can take practical precautions when interacting with DeFi protocols.
Users should review official announcements, avoid signing unfamiliar transactions, and confirm that applications have announced compatibility with the final upgrade. Using a reputable hardware wallet can help protect private keys from malware and phishing attempts. Ethereum users who prefer a regulated exchange may also compare platforms such as Kraken or Bitvavo, depending on their location and custody needs.
Keeping important credentials in a hardware wallet, such as a device available through Ledger, can add an extra layer of protection. A hardware wallet stores private keys offline and requires physical confirmation for supported transactions.
Could AI become standard for Ethereum upgrades?
This initiative may become part of a broader move toward more systematic upgrade testing. Modern networks contain thousands of contracts with complicated dependencies, making manual analysis increasingly difficult. AI-assisted simulation could allow researchers to explore more scenarios and identify unusual interactions earlier.
Its value will ultimately depend on transparency, accuracy, and responsible deployment. Researchers should explain which tools generated each finding, how false positives were handled, and whether independent developers can reproduce the results.
Conclusion
Ethereumβs decision to delay the Glamsterdam test on Hoodi follows the identification of potential risks across 13 smart contracts, with AI researchers assisting the investigation. The move demonstrates that upgrades can affect old code in unexpected ways and that extensive testing remains essential. Users should await verified developer updates, monitor contract compatibility, and continue following basic wallet-security practices. For now, the delay is a precaution intended to resolve unresolved risks before a mainnet upgradeβnot proof that Ethereumβs broader roadmap has been abandoned.
