Subly
Subly is a privacy-first PayFi protocol that converts DeFi yield into automatic subscription payments. Users deposit USDC once, and earned yield covers recurring costs without exposing payment details. Powered by Arcium's Cerberus multi-party computation (MPC), Subly shields transaction data while enabling seamless payouts to merchants via PayPal, eliminating the need for users to manage individual payment obligations.
