Complyr is an onchain payments system with a built-in private audit layer.
Each payment carries encrypted audit data such as expense category and jurisdiction, stored alongside the transaction onchain. This removes the need for offchain audit ledgers and manual reconciliation.
Using Zama’s Fully Homomorphic Encryption (FHE), auditors can run checks directly on encrypted records without decrypting the underlying data. The system evaluates audit conditions on ciphertext and returns a result, allowing auditors to identify flagged transactions without accessing the full dataset.
Only flagged records can be decrypted for investigation. All other audit data remains private.
This demo walks through:
Creating payments with encrypted audit records
Viewing encrypted records onchain
Granting auditor access
Running audit checks on encrypted data using FHE
Revealing only flagged records while preserving privacy
Built for the Zama FHE Hackathon.
