A payment gateway secured by stake, not trust.

Most payment gateways ask you to trust a company: a compliance team, a chargeback process, a reputation score nobody outside the company can verify. That trust is opaque by construction — you can't audit a private ledger.

Ootle Pay is a third-party payment gateway, built as three smart contracts on Tari Ootle, that replaces that opaque trust with a bond: merchants post a public, slashable stake instead of passing KYC. Every order and every subscription renewal is a plain event on a public chain, so a merchant's order history and revenue are auditable by anyone — not just asserted by a platform.

What actually lands on-chain

Not a mockup — the real event emitted by transaction 7be93988…69f8a3f2 on the esme testnet, next to what a typical processor keeps locked in a private database.

How it works

A merchant stakes to register

Public and slashable — merchant_registry ties a tier (Basic / Standard / Premium) to how much a merchant has staked, so accountability doesn't depend on anyone trusting the platform, or the platform trusting the merchant.

A customer buys a product

storefront checks the merchant is registered, takes the payment into a per-product revenue vault, and emits an OrderPlaced event — so the merchant's order count and revenue for that product are a chain query away, not a number they self-report.

Or subscribes to a plan

subscription tracks each subscriber by their own account, advancing billing periods that the merchant drives (there's no on-chain wall-clock), and pays plan revenue into a vault only that plan's merchant can claim.
