FAQs

USDCx on Aleo is one of the first private, programmable, dollar-denominated stablecoins on the Aleo network. It is fully backed 1:1 by USDC held in Circle xReserve, a secure infrastructure provided by Circle. Unlike traditional stablecoins on public blockchains where every transaction is visible to the world, USDCx on Aleo leverages zero-knowledge (ZK) cryptography. This allows businesses and individuals to transact with the speed and global reach of a digital dollar, while keeping sensitive financial data—such as payroll amounts, vendor payments, and personal spending—confidential.

  • Native USDC is issued directly by Circle (or its regulated affiliates) on supported blockchains and is backed by cash and cash-equivalent assets. On most chains, its transaction history is publicly visible.
  • USDCx on Aleo is minted on Aleo via Circle xReserve. It is backed 1:1 by native USDC deposited in the xReserve contract. Crucially, USDCx on Aleo benefits from Aleo’s privacy-preserving architecture, meaning transaction details (sender, receiver, amount) are encrypted by default and not visible to the public.

Circle xReserve is the infrastructure that enables blockchain teams to deploy a USDC-backed stablecoin, such as USDCx on Aleo. It is a set of smart contracts and APIs that enables secure interoperability between USDC and USDCx across supported blockchains. Here is how it works: 1. Secure Backing: For every unit of USDCx on Aleo minted, an equivalent amount of USDC is locked in a Circle-managed smart contract on Ethereum. This ensures USDCx is always fully backed. 2. Minimized Trust: xReserve uses cryptographic attestations to verify deposits and withdrawals, reducing the need for vulnerable third-party bridges. 3. Interoperability: It allows for seamless 1:1 transfers between USDCx on Aleo and the broader USDC ecosystem.

USDCx on Aleo benefits from a dual-layer security model: 1. Reserve Backing: USDC backing assets are held in xReserve smart contracts deployed by Circle, with minting and redemption verified through attestations. 2. Network Security: The transaction layer is secured by Aleo’s decentralized, zero-knowledge proof consensus mechanism, which mathematically verifies transactions without revealing the underlying data.

The combination of a transparent reserve (USDC) and a private ledger (Aleo) accelerates transformative use cases that were previously impossible on public blockchains: - Confidential Payroll: Pay a global workforce instantly in digital dollars without revealing salaries to the entire company or public. - Private B2B Payments: Settle vendor invoices and supply chain payments on-chain without exposing sensitive commercial relationships or pricing data to competitors. - Atomic Settlement: Execute complex financial operations (like trading or lending) 24/7 with instant settlement, ensuring data is revealed only to the counterparty and necessary auditors.

You can acquire USDCx on Aleo by bridging your existing USDC from supported networks (like Ethereum) to Aleo via the xReserve infrastructure. This can typically be done through authorized partners or directly within supported Aleo wallets, such as the Shield Wallet.
