What makes it different
Single identical payment gate that works across ten different web stacks without requiring accounts or API keys
100% of payments go directly to site owners' wallets with no custody or intermediaries
Runs by one person with nineteen live paid services and no outside capital
All services self-serve and automated by design with on-chain settlement
Bounded blast radius: compromised agents can only spend remaining epoch allowance on whitelisted targets
Passkey root stays on user's device; cloud holds only scoped, expiring session keys
Fully self-hostable open protocol with Apache-2.0 licensing
Approval workflows follow real organizational structure, not smart contract code
No token or cryptocurrency knowledge required to use the cloud platform
