EMA Price (Oracle)

The exponential moving average price published by Pyth alongside the spot price for each feed. EMA price smooths out short-term price spikes and is more resistant to manipulation than the instantaneous price. Lending protocols often use EMA prices for liquidation calculations to prevent unnecessary liquidations from brief price wicks. The EMA window is typically configured for several minutes of price history.

Grafo conceitual

Veja o termo como parte de uma rede, não como uma definição sem saída.

Esses ramos mostram quais conceitos esse termo toca diretamente e o que existe uma camada além deles.

Ramo

Pyth Network

A high-frequency oracle network publishing price feeds for crypto, equities, commodities, and FX. Pyth aggregates data from 90+ first-party publishers (market makers, exchanges) and updates prices every 400ms on Solana. Each price feed includes a price, confidence interval, and exponential moving average. Pyth uses a pull model with Hermes for cross-chain delivery.

Ramo

Feed de Preços

An on-chain account maintained by an oracle (Pyth or Switchboard) containing the current price, confidence interval, and timestamp for an asset pair (e.g., SOL/USD). DeFi programs read price feeds to calculate collateral values, trigger liquidations, and determine swap rates. Feed staleness must be checked to prevent using outdated prices.

Ramo

TWAP (Time-Weighted Average Price)

Time-Weighted Average Price—an average price calculated over a specific time period, weighting each price equally by time. TWAP oracles reduce manipulation risk vs. spot prices. Some DEXs (e.g., Jupiter) offer TWAP execution that splits large orders over time. Pyth provides EMA (exponential moving average) prices as a similar anti-manipulation measure.

DeFi

Emission Schedule

The planned rate at which new tokens are minted and distributed over time, typically defined in a project's tokenomics documentation. Emission schedules cover staking rewards, ecosystem incentives, and team/investor unlocks. SOL's emission schedule started at 8% annual inflation, decreasing 15% per year toward a long-term rate of 1.5%. High emissions relative to demand create sell pressure.

DeFiindex-price

Index Price

The reference spot price sourced from oracle feeds (Pyth, Switchboard) used as the benchmark in derivatives trading. Index price represents the aggregate market price across major exchanges and is used to calculate funding rates and as a component of mark price. Accurate index prices are critical for fair liquidation and funding rate calculations in perps protocols.

DeFimark-price

Mark Price

The fair value price used by perpetual contract platforms to calculate unrealized PnL and trigger liquidations. Mark price is typically derived from a combination of the oracle index price and the order book or AMM mid-price, weighted to resist manipulation. Using mark price instead of last traded price prevents liquidation hunting through short-lived price spikes on thin markets.

DeFioracle-staleness

Oracle Staleness

The condition where an oracle price feed has not been updated within an acceptable time window, making the price data potentially unreliable. Stale prices can lead to incorrect liquidations, mispriced trades, or exploitable arbitrage. Solana DeFi protocols must check the timestamp of oracle updates and reject or pause operations when prices exceed a staleness threshold (e.g., 30 seconds for Pyth feeds).

DeFi

AMM (Formador 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.
