Payroll nobody
else can read.

Salaries live on-chain as ciphertexts. Your employer runs payroll without seeing what anyone else earns. Employees decrypt only their own pay — locally, with a wallet signature.

On-chain state
Alice salary
0x8f2a…c4d3euint64 ciphertext
Bob salary
0x1c9e…7a12euint64 ciphertext
Carol salary
0xf03b…2e98euint64 ciphertext
Alice decrypts hers
0x8f2a…c4d3→$8,400

Bob and Carol still see only ciphertexts.

How it works
01Employer

Generate one-time codes for each hire. Share off-chain — Slack, email, anything.
03Employee
Claim & register
Enter the code in the app. Your wallet address gets linked to your record.
04Both
