USDC-native recurring payments for Arc Network.
Secure, upgrade-safe billing infrastructure for stable, predictable subscription flows.
Web3 wasn't built for subscriptions.
- No native recurring stablecoin flows
- dApps implement fragile, ad-hoc billing logic
- No standard for renewals, timestamps, or grace periods
- Secure and upgrade-safe subscription engines don't exist
SubArc fixes this at the protocol level.
- Automated USDC subscription logic
- Upgrade-safe UUPS architecture
- Built-in grace periods and renewal engine
- Clean developer experience with SDK + API + webhooks
