Aztec has launched the alpha version of its v5 execution layer, enabling private smart contracts on Ethereum through zero-knowledge proofs that verify transactions without exposing sensitive data. The architecture moves private computation to user devices while supporting hybrid public-private state, targeting decentralized finance and enterprise applications.

This Wire brief sits within Fusion42's coverage of Crypto & Web3. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

The Wire takeaway

If you're building confidential finance or compliance tools on Ethereum, you just got a free privacy layer that doesn't require users to exit the public ecosystem. Client-side execution plus selective disclosure means you can now sell privacy as a feature, not a workaround.
