Taurus, the Swiss digital asset infrastructure company whose clients include Deutsche Bank, has deployed the first private stablecoin smart contract on the Aztec layer 2. What is it?
The first confidential stablecoin is launched by Taurus
Taurus is a Swiss company founded in 2018 that specializes in digital infrastructure for professionals, including Deutsche Bank. This infrastructure covers cryptocurrencies, NFTs, digital currencies, and tokenized assets (RWA). Today, the firm announced the rollout of the first private stablecoin smart contract.
This offering is aimed at providing users with almost complete privacy in their transactions, while allowing certain authorized entities, including issuers, regulators, and law enforcement agencies, to access them if necessary.
To work as real digital cash, a stablecoin must hide your transactions and account balance from friends & foes while complying with the law. That doesn’t exist today. But we’ve just built the first building block: a private stablecoin program on @aztecFNDhttps://t.co/rSkW3hiGyZ pic.twitter.com/979QjK4Mnq

Taurus specifies that this smart contract has been deployed on Aztec’s testnet, a privacy-focused layer 2 solution for Ethereum, and is based on zero-knowledge proofs (ZKP). But why a privacy-focused stablecoin? For salary payments, daily payments, or transfers, according to Arnaud Schenk, executive director of the Aztec Network board of directors:
The global surveillance imposed by public blockchains is a barrier to the real adoption of stablecoins. For practical use cases such as payroll, intra-group transfers, or everyday payments, it is essential that transactions are not visible to everyone on an immutable ledger. Aztec’s Layer 2 solution is the only one that offers rigorous privacy to users, with controls defined by issuers directly at the token level.
In short, all transactions based on this smart contract will be encrypted, except for authorized parties, i.e., regulators and issuers. It is therefore not 100% confidential. However, this addresses “the recurring concerns of banks, central banks and regulators on this issue,” says JP Aumasson, Chief Security Officer at Taurus.
The smart contract will incorporate centralized burn and minting features, the ability to pause or resume transfers, an event log, and a blacklisting mechanism to comply with anti-money laundering rules and sanctions obligations.
