Privacy-preserving stablecoins are coming to Aleo Mainnet: USDCx and USAD

Aleo is approaching a major milestone in the evolution of privacy-first blockchain infrastructure. With the upcoming launch of USDCx by Circle and USAD by Paxos on Aleo Mainnet, the network will welcome the first privacy-preserving stablecoins designed for real-world financial use cases.

This article explores the impact of the introduction of USDCx and USAD on the Aleo ecosystem and the broader Web3 landscape. We outline what makes Aleo uniquely suited for private stablecoins, explain how these new assets differ from traditional stablecoins, and highlight why their launch represents an important step toward practical, privacy-enabled finance. 

What is Aleo

Aleo is a Layer 1 blockchain designed to enable private applications by default. Built on zero-knowledge cryptography, Aleo enables developers to create decentralized applications where user data, transaction details, and application logic can remain confidential while still verifiable on-chain.

At the core of Aleo’s architecture is the use of zero-knowledge proofs, which enable computations to be validated without revealing the underlying inputs. This approach addresses one of the long-standing limitations of public blockchains, where transparency, while valuable, can expose sensitive financial and behavioural data.

By combining privacy-preserving execution with a scalable Layer-1 design, Aleo provides a foundation for applications that require confidentiality without sacrificing decentralization or security. As Aleo Mainnet matures, the network is increasingly well-positioned to support complex financial primitives, including stablecoins that offer built-in privacy guarantees.

Why privacy matters for stablecoins

Stablecoins play a central role in today’s Web3 economy, serving as a bridge between digital assets and real-world value. However, most widely used stablecoins operate on fully transparent blockchains, where transaction histories, balances, and counterparties are publicly visible by default.

While transparency is a core feature of public blockchains, it can become a limitation for many financial use cases. Individuals, businesses, and institutions may require confidentiality around payments, treasury operations, payroll, or on-chain financial strategies. In these contexts, fully public transaction data can introduce unnecessary exposure and operational risk.

Privacy-preserving stablecoins aim to address this gap. By leveraging zero-knowledge proofs, they enable hiding sensitive transaction details while maintaining verifiability and trust at the protocol level. This approach enables stablecoins to support a broader range of applications, from private payments to more advanced financial workflows, without compromising the underlying principles of blockchain-based systems.

USDCx by Circle: a privacy-preserving extension of USDC

USDCx is a privacy-preserving stablecoin issued by Circle on Aleo, designed to bring the familiar USDC standard into a confidential execution environment. Built specifically for Aleo’s zero-knowledge architecture, USDCx enables private transfers and interactions while maintaining the reliability and backing associated with USDC.

Unlike traditional USDC transactions on public blockchains, USDCx allows transaction details such as amounts and counterparties to remain confidential. At the same time, the asset is designed to preserve key properties required for trust and interoperability, including verifiability and adherence to established stablecoin standards.

Circle’s participation in Aleo’s ecosystem marks an important signal for the network. As one of the most established stablecoin issuers in the industry, Circle’s involvement demonstrates growing confidence in privacy-focused infrastructure and highlights the demand for stablecoins that can support real-world financial use cases without exposing sensitive data on-chain.

What the launch of USDCx and USAD means for the Aleo ecosystem

The launch of USDCx and USAD marks an important milestone for Aleo as a privacy-first blockchain. Stablecoins are a core building block for on-chain finance, and their availability in a privacy-preserving form significantly expands the types of applications that can be developed on the network, from private payments to more advanced financial workflows.

The involvement of established issuers such as Circle Reserve and Paxos Labs also reinforces Aleo’s position as a mature platform for building real-world financial infrastructure. Their participation signals growing confidence in Aleo’s technology and highlights the network’s readiness to support privacy-enabled assets at scale.

Everstake’s role in the Aleo ecosystem

Everstake has been supporting Aleo since its early stages as a genesis validator, contributing to the network’s stability, security, and long-term development. As Aleo transitions into a more mature phase with the introduction of privacy-preserving stablecoins, reliable validator infrastructure is critical to maintaining network performance and resilience.

“Everstake has supported Aleo since genesis, across both Testnet and Mainnet, driven by a shared focus on privacy-first blockchain infrastructure. Aleo demonstrates how zero-knowledge technology can enable private transactions at scale. For us, this partnership reflects a shared commitment to building secure, responsible, and future-ready blockchain systems. We look forward to supporting Aleo as its ecosystem grows.” — Bohdan Opryshko, Co-Founder and COO at Everstake

By participating in Aleo as a validator, Everstake supports the broader ecosystem growth and the deployment of production-ready applications on the network. This role aligns with Everstake’s focus on providing secure, enterprise-grade staking infrastructure across multiple blockchain networks, including emerging privacy-first platforms such as Aleo.

Last Words

The launch of USDCx and USAD on Aleo Mainnet is more than the addition of two new assets. It reflects a broader shift toward financial systems that respect privacy while remaining transparent where it matters. By enabling stablecoins to operate in a confidential environment, Aleo is laying the groundwork for real-world applications that require both trust and discretion.

As the ecosystem continues to grow, developments like these signal that privacy-first infrastructure is moving from experimentation to practical use. Supported by established issuers and reliable network participants, Aleo is shaping an environment where privacy becomes a natural part of on-chain finance rather than a trade-off.
