Rule Engine

Author payment policy in code — test it before it touches a transaction

Write routing, risk and 3DS rules in a readable rule DSL. Trial them in shadow mode against live traffic, verify each release with a simulation run, and trace every decision.

Readable DSL

Express policy as an all/any/not condition tree — every leaf is a field, an operator and a value, with 11 operators, versioned and reviewable like code.

Shadow mode

Run new rules against live traffic without affecting decisions, then compare outcomes before going live.

Publish gate

Every release is versioned and recorded with who published it and when; you can run a simulation and read its result before it goes live.

Decision trace

Every outcome is explainable: see exactly which rules fired and why, for any transaction.

Three execution models

First match, all match or weighted scoring — and instant rollback to any prior version.
