Aptos has launched Confidential APT on its mainnet, allowing users to encrypt token balances and transfer amounts without concealing transacting wallet addresses. The opt-in feature, integrated into Petra Wallet, uses zero-knowledge proofs (proofs without revealing data) and homomorphic encryption (computing on encrypted data) to validate transfers without exposing amounts. Only native APT is eligible initially, although the standard can support other tokens after governance approval. The rollout follows Proposal #188, approved around April 24-25, 2026, and about 15,000 APT had entered confidential pools by mid-August 2026. Aptos is positioning the system for payroll, corporate treasury and business-to-business payments, while retaining address-level transparency for compliance and fund tracing.
