Interest Rate Model

The algorithm a lending protocol uses to determine borrow and supply interest rates based on pool utilization. Most Solana lending protocols use a kinked (piecewise linear) model with a gentle slope below optimal utilization and a steep slope above it, creating urgency to repay when liquidity becomes scarce. Parameters include base rate, optimal utilization point, and slope values for each segment.

Estas ramas muestran qué conceptos toca este término directamente y qué existe una capa más allá de ellos.

Rama

Utilization Rate

The percentage of total deposited assets currently borrowed in a lending protocol, calculated as total borrows divided by total deposits. Utilization rate is the primary input to interest rate models: higher utilization drives up borrow rates to incentivize repayment and attract new deposits. Most Solana lending protocols (Kamino, MarginFi) target an optimal utilization of 70-90%, with rates spiking sharply above this threshold.

Rama

Borrow APY

The annualized interest rate paid by borrowers in a lending protocol, expressed as annual percentage yield with compounding. Borrow APY is determined algorithmically by the interest rate model based on the pool's utilization rate. On Solana lending protocols like Kamino and MarginFi, borrow APY typically ranges from 2-15% for major assets but can spike above 100% during high utilization periods.

Rama

Supply APY

The annualized interest rate earned by depositors (lenders) in a lending protocol. Supply APY equals the borrow APY multiplied by the utilization rate, minus any protocol fees. For example, if borrow APY is 10% and utilization is 80% with a 10% protocol cut, supply APY is approximately 7.2%. Depositors earn yield passively as borrowers pay interest on their loans.

Rama

Préstamo

A DeFi protocol that enables users to deposit tokens to earn yield and borrow tokens against collateral. Key Solana lending protocols include Solend, MarginFi, Kamino, and Save (formerly Solend v2). Lending rates float based on utilization (borrowed/deposited). Deposits receive interest-bearing receipt tokens representing their share.

DeFicoupon-rate

Coupon Rate

Annual interest rate paid by a bond issuer as percentage of face value. A 5% coupon on $1,000 bond pays $50/year. In tokenized bonds, coupon payments are automated as on-chain distributions. T-bills are zero-coupon (purchased at discount, redeemed at par).

DeFifunding-rate

Funding Rate

A periodic payment exchanged between holders of long and short perpetual contract positions to keep the perp price anchored to the spot price. When the perp trades above spot (positive funding), longs pay shorts; when below spot (negative funding), shorts pay longs. Funding is typically settled every hour on Solana perps platforms like Drift and Jupiter Perps. High funding rates create arbitrage opportunities.

DeFiopen-interest

Open Interest

The total value or number of outstanding derivative contracts (perpetuals, options) that have not been settled or closed. Open interest increases when new positions are opened and decreases when positions are closed. High open interest indicates active market participation and can signal strong conviction. Perps platforms use open interest caps to manage protocol risk exposure.

DeFi

AMM (Creador de Mercado Automatizado)

A protocol that enables token swaps using algorithmic pricing against pooled liquidity instead of matching individual buyers and sellers. AMMs use mathematical formulas (typically constant product x*y=k) to determine prices based on the ratio of tokens in a liquidity pool. On Solana, major AMMs include Raydium, Orca, and Meteora.

DeFi

CLMM (Concentrated Liquidity Market Maker)

An AMM design where liquidity providers concentrate their capital within specific price ranges instead of across the full 0-to-infinity range. CLMMs dramatically improve capital efficiency—LPs earn more fees per dollar deposited within their active range. If the price moves outside the range, the position becomes inactive. Orca Whirlpools and Raydium CLMM are leading implementations on Solana.

DeFi

Pool de Liquidez

A smart-contract-held reserve of two or more tokens that enables trading via an AMM. Users deposit token pairs in specified ratios to become liquidity providers and earn trading fees. Pools are identified by their token pair and fee tier. Pool depth (total value locked) determines price impact for trades.

DeFi

LP Token

A token issued to liquidity providers representing their proportional share of a pool's reserves and accrued fees. LP tokens can be burned to withdraw the underlying assets. The value of LP tokens changes as the pool's token ratios shift and fees accumulate. LP tokens are often stakeable in yield farming programs for additional rewards.
