Ethereum co-founder Vitalik Buterin has suggested using “transaction simulations” and other similar features to improve the user experience and security of Ethereum wallets and smart contracts.

Vitalik Buterin floats simulated transactions to enhance crypto security

Ethereum co-founder Vitalik Buterin just dropped a game-changing idea: transaction simulations built directly into Ethereum. Think of it like a preview mode for your crypto moves — you specify what you want to do, see exactly how it'll play out on-chain, then hit 'OK' or 'Cancel.' No more blind signings, no more nasty surprises.
In a Sunday X post, Buterin argued that security and UX aren't separate battles — they're both about user intent. Making sure protocols actually do what users think they're doing. His vision? Systems that double-check your actions before execution, with features like spending limits and multisig approvals that only fire when intent, outcome, and risk limits all align.
The goal? Make low-risk actions frictionless and dangerous moves harder. But here's the catch: Buterin admits defining 'user intent' is brutally complex. There's no perfect security solution because 'the user's intent' is a messy, multi-layered thing even users themselves don't fully grasp.

[It's not] because machines are 'flawed', or even because humans designing the machines are 'flawed', but because 'the user's intent' is fundamentally an extremely complex object that the user themselves does not have easy access to.

Buterin's fix: Good solutions make users specify their intention in multiple, overlapping ways. The system only acts when these specs align. Think of it as redundancy for human decision-making.

The blockchain trilemma strikes again

Security is one-third of Buterin's famous blockchain trilemma — alongside decentralization and scalability. While Ethereum's been grinding on scalability (hello, layer 2s) and decentralization, security's getting its moment now. This simulation pitch could be the next evolution in making crypto less terrifying for normies.
Bottom line: Buterin's pushing for crypto interfaces that don't just execute blindly but actually understand what you're trying to do. It's about building guardrails that feel invisible until you need them. The future of crypto UX might just be a 'simulate transaction' button that saves your assets from your own mistakes.
