The vision is clear, the mission is privacy.

Privacy is for all, including your agents

[Privacy Cash @theprivacycash]

We’re pausing Privacy Cash deposits temporarily.

When we started Privacy Cash, our goal was to make privacy tools for everyday people, not to enable crime. In light of the recent Binance hack, we want to make sure bad actors can’t use our product.

During the pause, we’ll continue strengthening our wallet screening system.

Withdrawals will remain available.

Stay tuned for updates on when the service will resume.

Thanks for understanding. Privacy is for everyone, but not for criminals.

This is becoming the norm.

I just let my AI agent plan date night.

The winners of the @TOKEN2049 Origins Hackathon are in, and...

The overall winner came out of the Cardano track.

Teams built agents that pay, get paid, and prove their work, on rails like x402 and Masumi.

Here are the winners. 🧵

Second place in the Cardano track: zx402. 🥈

zx402 is building a private funding rail for AI agents on Cardano: a shared stablecoin pool with zero-knowledge proofs, so agents can pay without revealing who funds them.

Looking forward to get more feedbacks here!

zkAPI cuts the link between a deposit and an AI session on Ethereum. zBase cuts the link between an agent wallet and an x402 seller on Base. The seller still gets a normal payment, and withdrawals have to clear an Association Set Provider, so the pool is not a blind mixer.

An agent can fund a zkAPI reservation from the pool without the model ever seeing the wallet. No joint integration yet. That is the piece we are building.

Base mainnet, open pilot: payments settle, but the set is still filling toward 30 depositors, so it is unlinkable, not crowd-anonymous yet.

[Ethereum Foundation @ethereumfndn]

Today the EF and OA announce zkAPI—a new means for private AI

Picture this: deposit ether into a vault, sign a zk proof, get a fixed amount of private inference. Advances like these help us move past middlemen's requirements that we link our data and identities.

1) The number of agents will keep growing
2) The number of agents that need to transact then keeps growing
3) Crypto and stablecoins will be their go-to payment rail

Yep.

Revolut handed over passports, KYC selfies, and Bitcoin histories after a fake government email.

That’s the problem with custodial apps: they keep the file that links you to your money.

zBase doesn’t.

No passport. No selfie. No identity file to leak.

You deposit once. Payments leave from a fresh wallet. The seller gets paid. The chain doesn’t name you.

[International Cyber Digest @IntCyberDigest]

‼️ BREAKING: Revolut handed over customers’ passport copies, verification selfies and full transaction histories to a malicious actor.

The actor sent lawful government information-demand emails using a genuine government domain that passed domain authentication.

Revolut later concluded they were not authentic.

Affected customers were notified on Friday. What may have been disclosed ranges from name, date of birth and home address to account statements, withdrawal records and complete Bitcoin transaction history.

The company says it has alerted the agency to the unauthorised mailbox on its domain, blocked the address and begun notifying regulators.

It has not named the agency, explained how someone obtained a mailbox there, or given a number of affected customers.

ZachXBT, who circulated the notices, believes the incident was limited in size and aimed at high-net-worth users.

[zBase @zbase__]

Added a Base privacy-pool subgraph on The Graph, verified against on-chain roots, plus a fail-closed pool-state MCP/CLI check before privacy payments.

Integrated World AgentKit for AgentBook identity, per-human free calls, persistent bounded replay protection, feature flags, and 15 tests.

Hardened mainnet safety with a production-safe registry guard and Base RPC-compatible 2,000-block log scans.

Here's what we built at ETHOnline 2026 hosted by @ethglobal:

🥷 zBase – zBase enables private x402 agentic payments onchain, using ZK Privacy Pools and sanctions screening.

Updated two things: helping agents make honest privacy decisions and making paid API trials harder to farm.
