Key Highlights
- Vitalik Buterin described open financial systems as fundamental to the long-term purpose of Ethereum.

Ethereum co-founder Vitalik Buterin said decentralized finance (DeFi) remains a central pillar of Ethereum Foundation priorities, describing open financial systems as fundamental to the long-term purpose of Ethereum.
In an X post on Tuesday, Buterin argued that financial access plays a key role in individual autonomy and that Ethereum’s development should continue to support permissionless financial tools alongside other applications.
He noted that decentralized finance is not the only use case for Ethereum, but remains one of its most significant contributions.
Emphasis on open and permissionless systems
Buterin outlined a specific direction for decentralized finance development rather than broad support for all on-chain financial products. According to him, priority should be given to systems that are:
- Permissionless
- Open-source
- Security-focused
- Resistant to centralized control
- Designed to function without reliance on a founding team
He suggested that protocols should continue operating even if their original developers disappear or become compromised, describing this resilience as an important benchmark.
Expanding beyond early DeFi models
Buterin pointed to early innovation in decentralized finance as a model for future work, highlighting new financial designs such as automated market makers. He encouraged developers to focus on underlying financial needs, such as risk management and hedging, rather than incremental improvements to existing products.
He said decentralized finance has already demonstrated the ability to offer savings and risk-management tools without intermediaries, but further development is needed.
Areas for improvement
The Ethereum Foundation identified several areas for improvement across the decentralized finance ecosystem. The organization highlighted both established and emerging approaches to improving safety, including:
- Smart contract audits and technical standards
- Wallet-based safeguards
- Formal verification tools
- AI-assisted security analysis
Privacy was identified as another major focus, including:
- Confidential payments
- Privacy-preserving lending systems
- Reduced exposure to liquidation-related strategies
Selective support from the Ethereum Foundation
Buterin said the Ethereum Foundation does not plan to support decentralized finance projects indiscriminately. Instead, it intends to work with developers aligned with its goals of minimizing intermediaries and increasing user control over assets.
He said Ethereum’s open structure allows any project to launch, but the foundation will prioritize efforts that strengthen permissionless financial infrastructure.
