Today’s Big Story

Private by Default: Unpacking Aleo’s USAD Stablecoin

Last week, the Aleo Network Foundation and Paxos announced USAD, a U.S. dollar–backed stablecoin built on the Aleo L1.

Yes — this yet another entrant in the crowded new-stablecoin PR announcement bubble, but its designs point toward a critical missing piece of the puzzle towards the enterprise adoption of tokenized rails: privacy.

On networks like Aleo, transactions are private by default, meaning information including sender, receiver, and amount are encrypted. Additionally, they can be programmed to carry proof of compliance.

Transparency: Feature or a Bug?

Transparency has often been touted by crypto enthusiasts as one core features over legacy railings. However, the open ledgers that enable trustless real-time transactions, are also exploited in less desirable ways:

MEV bots extract value by reordering trades in the mempool.
Whale trackers can replicate institutional order flow.
Analytics providers undo the pseudonymity of wallets and commercialize address-level data (that would be regulated as PII in most jurisdictions).

For institutions and enterprises making their way into crypto, this transparency breaks two pillars of financial infrastructure: execution confidentiality and data-protection compliance. For instance, a payments firm subject to GDPR, PSD3, or CCPA cannot process payroll or customer flows on fully public rails.

Not Unique to Crypto

Every time technology has made financial data too visible, discretion has been re-engineered:

1867 – Ticker tape: “Real-time tape created information asymmetries; over time, exchanges introduced consolidated tapes and quote-publication controls to curb front-running
1977 – Telex: Telex messages were replaced by SWIFT’s authenticated, standardized network in 1977; widespread message encryption followed in the late 1980s–1990s
1992 – Black Wednesday: real-time FX terminals exposed the Bank of England’s defense of sterling, accelerating speculative attacks; central banks responded by anonymizing and delaying disclosures of interventions.

Privacy ≠ Opacity

Contrary to popular belief, regulators don’t object to privacy; they object to opacity and asymmetric information. For instance GENIUS and MiCA mandate redeemability and AML; neither requires publishing every transfer’s plaintext on a public ledger.

Zero-knowledge proofs

This is where zero-knowledge proofs provide a path forward, as they provide way to show the validity of a claim, without disclosing the underlying information that supports them. What they enable is controlled transparency; data remains encrypted, yet regulators or verifiers can confirm compliance.

In practice, this opens the possibility for auditors to satisfy AML, KYC, and jurisdictional checks, while keeping others information private, and while all of this remains hidden to other market participants. For example:

KYC membership: proving a wallet’s inclusion in a regulator-approved registry.
Sanctions non-membership: proving a public-key hash is not on OFAC’s list.
Range proofs: demonstrating cumulative transaction value ≤ $10,000 per month for AML monitoring.
Reserve attestations: aggregating off-chain auditor signatures to confirm assets ≥ tokens outstanding.

This is a structural advance over today’s “view-everything or view-nothing” model used in centralized compliance systems. They move supervision from post-hoc audits to real-time verification.

How Crypto Is Tackling It

OGs: Monero (2014) made all transactions private, while Zcash (2016) pioneered a viewing-key model that enabled for selective disclosure.

Aztec Network (relaunching 2025) takes this further by combining selective privacy with the programability of smart contracts. This enables use cases like private DeFi execution and mitigating MEV. Aleo, codes privacy and zk-proof checks into its consensus layer (e.g. The network can enforce “sender ∈ whitelist” or “transaction ≤ limit” before execution), a reason heavily regulated firms are Worldpay, Revolut, and Google Cloud have launched pilots.

Together these efforts form an emerging privacy-compliance stack, where execution, verification, and auditability are modular but interoperable.

What to Watch

Regulatory signals: the FATF and European Banking Authority are reviewing “ZK-attested transactions” under the Travel Rule. Early recognition would de-risk institutional adoption.

Standardization: initiatives like ZKProof.org and W3C VC for ZKPs aim to unify proof formats across Aleo, Aztec, and Polygon ID by 2026.

Interoperability: projects such as Succinct Labs and Hyperlane are developing proof-bridges that could allow privacy-preserving assets to interact with public DeFi liquidity pools without leaking trade data.

Top News in the Past 24 Hours

Plasma Struggles to Reclaim Post-TGE Momentum After a highly successful launch, the XPL token has fallen almost 50% from its opening week high. Some contributing factors to the selloff could include liquidity incentive emissions, and ICO whales selling large quantities of tokens. Why it matters: Plasma’s token launch was highly anticipated, but its pre-ICO deposit vault process was not without controversy.
Lighter Points Hit $100 on OTC Markets Traders are flocking to tokenless perp DEX Lighter in pursuit of “the next Hyperliquid airdrop,” the exchange’s activity-based points have hit an all-time high on OTC markets. Why it matters: The recent rise of fellow perp DEX Aster has sparked a mania in the sector, and now Lighter and Hyperliquid are neck and neck in terms of trading volumes.
ZORA Surges 40% on Robinhood Listing Creator-focused Ethereum Layer 2 network Zora was listed today on brokerage app Robinhood, sending the ZORA token flying. Why it matters: ZORA is the latest addition to Robinhood’s crypto lineup, which is expected to continue to grow after the company's series of announcements in June.
