According to The Block, Aztec Labs has relaunched zk.money, a self-custody privacy wallet whose service was terminated in 2023, after three years. The new version runs on Aztec's Ethereum Layer 2 network and features user balances, transfer amounts, and counterparty information not being disclosed on the public ledger. The original zk.money was launched in 2021 and processed over $100 million in transactions from more than 75,000 wallets, but its operation was suspended due to scalability issues.
