Vitalik has published two pieces in the past two months that together make the case for why AI agents need cryptographic privacy at the payment layer. Nobody else has laid it out this clearly. The first, co-authored with Davide Crapis (the EF’s AI lead) on ethresear.ch in February, proposes a protocol called ZK API Usage…

At 02:47 AM, an autonomous operations agent named Nova quietly renews a domain. No alerts are triggered. No procurement tickets are created. No one from the finance team is awake. Yet a critical part of the company’s digital infrastructure has just been secured for another year. At scale, even the smallest operational payments become strategic signals. Nova…

Curvy is a privacy infrastructure for EVM-compatible blockchains, and one of the workloads it was built for is autonomous agent payments – the kind of always-on, programmatic spending that AI agents, scheduled bots, and machine-to-machine services do without a human at the keyboard. This post explains why agents need privacy in a way that human…

Curvy is a privacy infrastructure for EVM-compatible blockchains. The Curvy SDK is the developer surface for that protocol: it generates stealth meta-addresses, derives per-payment destinations, scans announcements, and signs from the resulting addresses, across every chain Curvy supports. If you are integrating private payments into a wallet, payroll tool, merchant flow, agent platform, or treasury…

There is a recurring question in on-chain private payments: which is better, stealth addresses or shielded pools? It is the wrong question. The two designs protect different parts of a transaction, and most serious privacy programs end up using both. Curvy is the stealth-address option in that pairing. Curvy is a privacy infrastructure for all…

Curvy Protocol is a privacy infrastructure for EVM-compatible blockchains. The shorter answer to “why does this exist” is that every previous approach to on-chain privacy treated it as a feature you opt into, when it actually needs to be a property of the system. This post is the long version. The problem the team kept…
