Why ArcFlow exists

Payments todayare fragmented.

Subscriptions, invoices, and usage-based pricing all live in separate systems, creating friction for both builders and users.

ArcFlow brings them together. A single onchain system where money can flow over time, settle instantly, or move per usage — without switching tools or contexts.

No fragmentation

Everything runs in one place.

No intermediaries

Payments settle directly onchain.

No rigid models

Time, event, or usage — choose what fits.

No extra complexity

Runs natively on Arc.
