Aptos Rolls Out "Confidential APT" on Mainnet, Adding Opt-In Privacy for Transaction Amounts

Aptos has launched Confidential APT on its mainnet, introducing an opt-in privacy feature that encrypts token balances and transaction amounts while keeping wallet addresses visible onchain. The Layer 1 blockchain, which markets itself on high throughput and low transaction fees, is positioning the upgrade as a way to add financial confidentiality in a public, auditable environment. On most public networks, block explorers allow anyone to view a wallet's balance and the exact value of each transfer. Confidential APT changes this partially: it hides the "how much" but not the "who." Both sender and receiver addresses remain identifiable, a design choice Aptos says supports accountability and regulatory alignment. To ensure transactions remain verifiable despite encrypted amounts, Aptos relies on zero-knowledge proofs, a cryptographic technique that can prove a transfer is valid without revealing the underlying figures. The proofs are intended to prevent double spending and the creation of tokens outside the rules. Aptos emphasized that Confidential APT is optional. Users can continue transacting transparently as before, while those enabling confidentiality can also use selective disclosure to share balances or transaction details with approved parties such as auditors or business partners. The company is targeting compliance-sensitive institutional use cases including payroll, treasury operations, and B2B or intercompany settlement, where exposing payment flows or salary figures could create operational or competitive risk. Aptos announced the mainnet rollout on August 4, 2026, stating that addresses remain visible, amounts stay encrypted, and zero-knowledge proofs validate each confidential transaction.
