We’re excited to announce that Aptos Confidential Transactions (ACTs) are now live on devnet!
What Are ACTs?
Confidential Transactions allow you to encrypt on-chain balances and transfer amounts, making them invisible to validators and the public, while still ensuring auditability.
Confidential token balances & transfer amounts- Selective disclosure for authorized auditors
- No visibility to validators or other participants
- No hidden identities — sender & recipient remain public
Perfect for regulated finance and enterprise-grade use-cases needing privacy and compliance.
How It Works
ACTs use:
- Homomorphic Encryption to perform balance updates without decrypting values.
- Zero-Knowledge Proofs (ZKPs) to prove correctness of transactions (e.g., no overspending) without revealing amounts.
Example:
When Alice sends tokens to Bob:
- She encrypts the amount under her key, Bob’s key, and optionally an auditor’s key.
- She generates a ZKP proving the value is valid and she has enough balance.
- Validators verify the proof, update balances — without seeing the actual amounts.
- Bob decrypts and sees the amount.
