Ramp Contracts are designed to secure API transactions with precise, enforceable rules. Step-Up Authentication adds a dynamic control layer: when a request triggers a sensitive clause—like high-value transfers or admin-level changes—the system forces the caller to verify again before the contract proceeds. It’s not static security. It’s conditional, adaptive, and always on guard.
At the core is the interplay between contract conditions and authentication logic. Each contract defines thresholds: transaction amount, operation type, risk score, or origin IP. A match against these thresholds switches the session state from confirmed to pending verification. Ramp makes this state change seamless but unskippable.
Step-Up Authentication relies on trusted identity providers, token validation, and strong cryptographic checks. Multistep flows can be configured to use passkeys, hardware keys, or secure one-time codes. All of it runs inside the contract’s decision loop, so authentication is not an external patch—it’s part of the execution path.
