# Omnipair uses adaptive target utilization range not fixed kink curve for interest rate control

Omnipair's interest rate controller uses a configurable target utilization range (currently 30%-50%, previously 50%-85%) rather than a fixed utilization-interest curve with a kink point. The system increases borrow rates as soon as utilization hits the upper bound of the target range, creating dynamic adjustment rather than the static kink-curve model used by protocols like Aave.

This design choice reflects operational constraints from shallow liquidity and dynamic LTV, which make it "hard to go beyond ~55% utilization" in practice. The founder explicitly frames this as addressing "capital fragmentation between lending and spot" — positioning Omnipair as unified infrastructure rather than separate lending markets.

## Mechanism

The rate controller is mechanistically distinct from Aave-style fixed kink curves in that:
- It targets a utilization *range* (30-50%) rather than a single kink point
- Rates increase at the lower bound (50%) rather than at a discrete threshold
- The range is configurable per market, not protocol-wide
- Previous markets used 50-85% range, indicating the parameter is actively tuned against observed behavior

## Evidence

"All @omnipair interest rate controllers are configurable. We don't use a fixed utilization-interest curve, but rather a target utilization range. The current markets use a 50%-85% range, and given shallow liquidity plus dynamic LTV, it's hard to go beyond ~55% utilization. We've upgraded the default config to a 30%-50% target range. This increases borrow rates as soon as utilization hits 50%." — @rakka_sol, 2026-02-21

## Operational Context

Shallow liquidity + dynamic LTV creating a ~55% utilization ceiling is real friction evidence from early-stage deployment. This constraint drove the parameter change from 50-85% to 30-50%, indicating the mechanism is being tuned against live market behavior rather than theoretical optimization. The upgrade suggests the protocol is responding to observed capital utilization patterns.

## Strategic Intent

The founder's explicit framing—"Omnipair should be the primary place for capital, no more fragmentation between lending and spot"—indicates this rate controller design is part of a unified infrastructure thesis, not just a technical optimization.
