SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps users understand and compute Comet V3's kinked interest rate model, including how supply and borrow rates react to utilization changes.

Core Features & Use Cases

  • Explain the kinked rate formula for supply and borrow, including base, slopeLow, slopeHigh, and kink thresholds.
  • Compute utilization and translate it into current interest rates and accrual implications.
  • Use Case: evaluate rate scenarios for a given asset in a new deployment or during protocol upgrade planning.

Quick Start

Explain the supply rate at 85% utilization.

Frequently Asked Questions about Comet Interest Rates

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How does the kinked interest rate model work in Comet V3?▼

The kinked interest rate model uses base, slopeLow, slopeHigh, and kink thresholds to calculate supply and borrow rates that react dynamically to utilization changes for single-asset bases.

How do I calculate utilization-driven supply and borrow rates for Comet?▼

Compute utilization by dividing borrowed assets by total supply, then apply the kinked rate formula to derive current supply and borrow rates and accrual implications.

What is the supply rate at 85% utilization in a kinked rate model?▼

At 85% utilization, the supply rate is calculated by applying the configured base rate and slopeLow parameters up to the kink threshold to determine the yield accrual.

Can I evaluate rate scenarios for a new Comet deployment using Solidity-like pseudocode?▼

Yes, you can compute on-demand rate logic using Solidity-like pseudocode to evaluate utilization-driven rate changes for single-asset bases during protocol upgrade planning.

Why do borrow rates spike when utilization crosses the kink threshold?▼

Borrow rates spike because the model switches from slopeLow to slopeHigh once utilization exceeds the kink threshold, sharply increasing rate accrual to incentivize liquidity repayment.

How do index-based calculations affect rate accrual in Comet V3?▼

Index-based calculations track rate accrual over time by applying the computed supply or borrow rate to the principal, continuously updating the base for interest generation.
