Perpetuals

Perpetual Contracts

Overview

Perpetual contracts (Perpetual Futures) are a type of cryptocurrency derivative that allows traders to speculate on the future price of an underlying asset without actually owning it. The key difference from traditional futures contracts is that perpetual contracts have no fixed expiration date and can be held indefinitely.

Core Characteristics

No Expiration Date - Traditional futures contracts have a specific settlement date - Perpetual contracts can be held permanently with no forced liquidation time - Traders can decide when to close their positions based on market conditions

Funding Rate Mechanism - To ensure the contract price stays anchored to the spot price, a periodic funding fee payment system is used - When the perpetual contract price is above the spot price, long position holders pay short position holders - When the perpetual contract price is below the spot price, short position holders pay long position holders - Funding rates are typically settled every 8 hours

Leveraged Trading - Supports high leverage, typically ranging from 10x to 125x - Allows traders to control larger positions with smaller capital - Amplifies potential profits while also amplifying risks - Requires maintaining a certain margin ratio, otherwise forced liquidation occurs

How It Works

Margin System - Initial margin: The minimum capital required to open a position - Maintenance margin: The minimum capital level required to maintain a position - Liquidation is triggered when the account balance falls below the maintenance margin

Mark Price - Uses the mark price rather than the last traded price to calculate unrealized profit and loss - Prevents market manipulation and malicious liquidation - Typically based on index prices from multiple spot exchanges

Auto-Deleveraging (ADL) - A risk control mechanism for when counterparty liquidity is insufficient - Ranked by profit rate and leverage ratio, prioritizing the reduction of high-profit, high-leverage positions - Ensures overall system risk remains manageable

DeFi Perpetual Contracts

Decentralized Advantages - Non-custodial trading; users maintain full control of their assets - No KYC required, protecting user privacy - Transparent on-chain settlement - Censorship-resistant, globally accessible

Risk Warning

Liquidation Risk - Leverage amplifies the impact of price fluctuations - Extreme market volatility can lead to rapid liquidation - It is recommended to use reasonable leverage levels and stop-loss strategies

Funding Rate Costs - Long-term positions require paying accumulated funding rates - In a one-sided market, funding rates may remain persistently negative - The impact of funding costs on returns needs to be calculated

Liquidity Risk - Insufficient market depth may cause excessive slippage - Positions may not be closed in time during extreme market conditions - Decentralized platforms generally have lower liquidity than centralized exchanges

Smart Contract Risk - DeFi platforms carry the risk of smart contract vulnerabilities - Security audit status of platforms should be carefully evaluated - It is advisable to diversify funds and not concentrate all assets on a single platform

Development History

  • 2016: BitMEX launched the first perpetual contract, innovatively combining traditional financial CFDs with crypto market characteristics
  • 2020: During DeFi Summer, platforms like dYdX began offering decentralized perpetual contract trading
  • 2021-2025: Multi-chain ecosystem development, with numerous perpetual contract protocols emerging on high-performance chains like Solana and Arbitrum
