MY CONTRIBUTION
Scope and ownership
I built five UUPS-upgradeable contracts around Zama fhEVM, including an encrypted USDC wrapper, private payroll, six-state escrow, threshold balance proofs, and stealth recipients. The implementation makes ciphertext access control, async public decryption, and selective disclosure explicit product concerns.
TECHNICAL EVIDENCE
What the work includes
- Encrypted balances, allowances, transfers, and total supply
- Private payroll, escrow, balance proofs, and stealth recipients
- Permanent and transient ciphertext access-control flows
- Twenty-eight contract tests across five deployed contracts
