Vitalik warns ETH smart wallets face risk

TLDR

Vitalik Buterin is warning that Ethereum smart wallets have a structural relay weakness that can let intermediaries block or stall user transactions until a protocol upgrade fixes it.

1. Many smart contract wallets and privacy tools rely on centralized relays to get transactions onchain, creating censorship and reliability risks.
2. Ethereum developers are planning FOCIL plus EIP?7701/EIP?8141 in the Hegota upgrade to rebuild the mempool and remove this relay dependence.
3. For users, the main near?term risk is stuck or censored transactions, while the longer term is a move to more private, censorship?resistant smart wallets.

Confidence: high because this is based on Vitaliks recent technical roadmap and multiple news summaries.

Deep Dive

1. Relay Dependence Risk

Vitalik Buterin highlights that many Ethereum smart contract wallets (account abstraction style wallets) and privacy protocols currently depend on third?party relay services just to get transactions included onchain. If a relay/bundler goes offline or refuses a transaction, the user often has no direct fallback route to the public mempool, which undermines Ethereums censorship?resistance guarantees as described in his comments on relay dependence.

This is especially sensitive for privacy tools, which already attract more scrutiny; if a few large relays all decide not to forward a certain type of transaction, those users can effectively be blocked from using the chain in practice.

2. Planned Ethereum Fixes

To address this, Buterin points to two Ethereum Improvement Proposals plus a new mechanism, all targeted at a major Hegota upgrade around late 2026: FOCIL, EIP?7701, and EIP?8141.

FOCIL (Fork?choice Enforced Inclusion List) would assign includer responsibilities to validators so valid transactions must be included within one to two blocks, making censorship structurally difficult and reducing reliance on trusted relays. EIP?7701 brings native account abstraction so all wallets can behave like smart contracts, while EIP?8141 adds features like gas sponsorship and quantum?resistant signatures at the protocol level, letting smart wallets submit directly to a rebuilt public mempool without intermediaries.

3. User Impact And What To Watch

In the near term, the practical risk is that a smart wallet relying on a specific relay could see transactions delayed or censored, especially for privacy?related flows, even though base?layer Ethereum remains live.

Over the medium term, watch for concrete milestones: implementation and testing of FOCIL, progress on EIP?7701/EIP?8141, and wallet support for sending through a public mempool once those land. These changes also tie into a broader privacy roadmap (AA, keyed nonces, Kohaku toolkits) aimed at giving Ethereum more money?like privacy properties while maintaining decentralization.

Conclusion

Vitaliks warning is not about an immediate catastrophic bug but about a structural reliance on relays that weakens smart wallets censorship resistance today. Ethereums roadmap aims to shift transaction inclusion and wallet programmability into the base protocol so that, over time, smart wallets become both more private and less dependent on any single intermediary.
