‘Vibe-coding 2030 roadmap within weeks’ – Buterin’s new Ethereum vision

For years, the main criticism of Ethereum was not its vision, but its slow progress. The often-mentioned 2030 roadmap felt far away.

But that changed on the 28th of February, when co founder Vitalik Buterin suggested that Ethereum’s timeline could now move at AI speed.

He highlighted a breakthrough in “agentic coding,” where AI agents helped build a working Ethereum client prototype aligned with long-term roadmap goals in just 14 days.

The project reportedly generated approximately 700,000 lines of code, covering 65 roadmap items. 

Expressing his excitement on the matter, Buterin added, 

Challenges in this roadmap

However, this rapid speed raises serious concerns. Even though the prototype synced with Ethereum’s mainnet, AI-generated code challenges the traditional review process.

Ethereum’s security has always depended on careful human auditing, and if AI can compress years of work into weeks, safety and verification must keep pace.

Despite generating around 700,000 lines of code, Buterin made it clear that AI is not ready to replace human developers.

 He added, 

What’s the solution?

That being said, the bigger story for Ethereum [ETH] is the speed of change.

Just six months ago, the idea that AI agents could independently build a client syncing with the mainnet felt unrealistic. Now, it is possible.

To address the risks, Buterin argues that AI should not be used only to move faster. Instead, developers should split the gains, using half the time saved for speed and the other half to strengthen security.

He also admits that 100% perfect security is likely impossible, as it would require a flawless connection between human intent and machine code, something that does not yet exist. However, he believes,

If this approach works, it could significantly accelerate Ethereum’s long-term roadmap. 

Ethereum account abstraction set to launch

Ethereum’s long-discussed account abstraction is finally set to arrive with the Hegota fork in 2026.

The upgrade, enabled by EIP-8141, will introduce “smart accounts” that simplify transactions by using frames for validation and execution.

Explaining this feature, Buterin applauded,

EIP-8141 will allow features like multi-signatures, quantum-resistant wallets, and flexible key management.

Users will also be able to pay gas fees in tokens besides ETH through paymaster contracts, reducing reliance on intermediaries.

The change enhances privacy protocols by removing public broadcasters and supports batch operations and transaction sponsorship.

ETH’s mixed market dynamics

Interestingly, this vision of Buterin came at a time when ETH was trading near $1,984, seeing a modest 6.11% gain in the past 24 hours.

Additionally, data from Santiment showed a clear gap wherein market sentiment remained cautious and uncertain, but Development Activity has jumped to its highest level in months.

In simple terms, traders are hesitant, but developers are working harder than ever. 

Acknowledging AI’s potential, even Circle’s CEO had noted that if AI agents are going to function in the real economy, the world will need much stronger digital dollar infrastructure. At the same time, Buterin is also reframing the AI-crypto narrative.

He has criticized the push toward AGI if it is driven purely by power. Instead, he views Ethereum as shared economic infrastructure where AI programs can make payments, post deposits as proof of trust, and operate without relying on a central authority.

Final Summary

• Buterin makes it clear that human expertise remains essential to secure core infrastructure.
• While traders remain cautious, builders are accelerating behind the scenes.
