Zarf
Confidential token distributions & payroll, sent to an email.
The first ZK project on Stellar Soroban, and the first email-first ZK payroll. Send tokens to an email address instead of a wallet: zero-knowledge email-ownership proofs mean no wallet setup for recipients and no leaked addresses, amounts, or transaction graph. Vesting and compliance live in the circuit.
01 · Challenge
Token distributions leak everything: recipient addresses, amounts, the whole transaction graph. And a recipient needs a wallet before they can even be paid.
02 · Decision
Send to an email instead. A zero-knowledge proof of email ownership claims the funds, and vesting and compliance rules live inside the circuit (Noir on Soroban).
03 · Outcome
Recipients need no wallet setup and observers learn nothing. Won a Stellar Community Fund award; live at zarf.to.
