About us

Keep your catalog, cart, and order system. Hand off the final step to a PYMSTR-hosted payment page and we do the rest: create wallets in-flow, apply your split policy, settle on-chain with atomic bundles, and include gas in the same currency the customer pays. You stay in control; we enforce your rules and deliver exact settlement, no more, no less.
