EVEDEX Trading Glossary

Key trading terms and definitions you’ll need to navigate EVEDEX with confidence. Simple, clear, and easy to reference anytime.

Updated over a month ago

This glossary explains the core concepts, trading mechanics, platform technologies, and features you’ll encounter while using EVEDEX. Whether you’re new to crypto or just learning the structure of decentralized trading, this reference will help you better understand how the platform works.

1. Core Concepts

Cryptocurrency

Digital assets secured by cryptography and recorded on public blockchains. Examples include BTC (Bitcoin), ETH (Ethereum), and USDT (a stablecoin pegged to the US dollar).

Blockchain

A decentralized ledger system that stores transaction records across a network. It ensures transparency, auditability, and data immutability.

Wallet

A tool that allows users to store and manage cryptocurrencies. EVEDEX supports non-custodial wallets (like MetaMask or Rabby) where the user retains full control of their private keys.

Private Key / Public Key

  • Private Key: A cryptographic key used to access and control funds. Must be kept secure.

  • Public Key: A wallet address that others can use to send funds to you.

Account Abstraction (AA)

Technology that simplifies wallet interaction by allowing programmable permissions and better UX without compromising security. Supported by EVEDEX to improve onboarding and trading flow.

Social Recovery

A recovery mechanism that allows users to regain access to their wallet using trusted third parties or devices—helpful in case of lost keys.

2. Order Types

Market Order

Executes immediately at the best available price. Prioritizes speed over price precision.

Limit Order

Executes only when the market hits a predefined price. Useful for setting controlled entries or exits.

Stop Order

Triggers an order when the market reaches a certain price. Often used for stop-loss or take-profit logic.

Stop-Limit Order

Combines a stop and a limit. When the stop price is reached, a limit order is placed instead of executing immediately.

3. Trading Mechanics

Leverage

A multiplier that allows you to open positions larger than your actual balance. EVEDEX supports leverage up to 100x on certain pairs.

Liquidation

Occurs when your margin is no longer sufficient to cover potential losses. The position is closed automatically to prevent further loss.

Slippage

The difference between the expected and executed price. More likely in volatile or low-liquidity markets.

Spread

The gap between the highest bid and the lowest ask. A narrower spread indicates higher liquidity.

Vaults

Smart contract-based liquidity pools used to fund trades on EVEDEX. Traders indirectly interact with vaults when opening or closing positions.

Matching Engine

The core system that matches buy and sell orders. EVEDEX uses DXmatch Technology for high-speed order execution while preserving decentralization.

4. Platform Architecture & Security

Non-Custodial

EVEDEX does not hold user funds. All assets remain in the trader’s wallet or in smart contracts they control.

Smart Contracts

Self-executing code that automates trades, positions, fees, and settlement processes on-chain.

Session-Based Trading

Allows temporary access and transaction approvals in a trading session, reducing the need for repeated wallet confirmations.

Permissionless Output Proposals (PoPs)

A safety feature allowing users to initiate L2-to-L1 withdrawals independently in case of sequencer downtime or failure.

5. Market Behavior

Liquidity

The ease with which assets can be bought or sold without affecting the market price. Higher liquidity = smoother execution.

Bid / Ask Price

  • Bid: The highest price someone is willing to pay for an asset.

  • Ask: The lowest price a seller is willing to accept.

Volatility

The rate and magnitude of price movement. Higher volatility increases potential opportunity and risk.

Support / Resistance

  • Support: A price level where buying pressure tends to prevent further decline.

  • Resistance: A level where selling pressure tends to halt upward movement.

Bull Market / Bear Market

  • Bull Market: Rising prices and strong market sentiment.

  • Bear Market: Declining prices and pessimism about future movement.

6. Ecosystem Technology (L2 and L3)

Layer 2 (L2)

Built on Ethereum to improve speed and reduce costs. EVEDEX operates on L2 networks for lower fees and faster execution.

Layer 3 (L3)

Custom networks built on L2 (like Arbitrum Orbit) that enable further scaling and feature flexibility. EVEDEX uses L3 to power advanced trading functionality.

Arbitrum Orbit / Nitro Stack

Infrastructure stack used to deploy EVEDEX’s high-performance Layer 3 chain, providing full EVM compatibility and improved throughput.

Optimistic Rollup

A type of L2 scaling solution used by EVEDEX. Assumes transactions are valid unless challenged, enabling lower-cost, high-speed operations.

Sequencer

A node or group of nodes responsible for ordering transactions in an L2 network. Plays a key role in EVEDEX’s trade processing.

AnyTrust Model

Security framework used on Arbitrum Nova, ensuring data integrity as long as one DAC member is honest. Relevant for scalability and data availability.

Data Availability Committee (DAC)

A group of entities ensuring transaction data remains accessible and verifiable in certain L2 setups.

7. Fees and Rewards

Maker / Taker Fee

  • Maker: Applies when your order adds liquidity (e.g., a limit order).

  • Taker: Applies when your order removes liquidity (e.g., a market order).

Gas Fees

Network fees required to execute on-chain actions. These vary by blockchain (Ethereum, Arbitrum, BNB Chain, etc.).

Gas fees: Ethereum is now cheaper than Polygon

Protocol Fees

Fees charged per trade on EVEDEX, collected via smart contracts and allocated to the protocol treasury.

Rewards Program

A system that grants points or perks for participating in platform activities, such as trading, referring users, or completing missions.

Reward Points

Internal scoring metric used to measure engagement. These may influence loyalty tiers or access to platform benefits.

8. Advanced Features

Perpetual Futures

Derivatives that allow traders to open leveraged positions without expiry. Positions can be held indefinitely as long as margin requirements are met.

Copy Trading

A feature that enables users to automatically mirror trades from experienced traders. Useful for newer users or passive strategies.

EVM / EVM+

  • EVM: Ethereum’s virtual machine for running smart contracts.

EVM+: An enhanced version offering more programming flexibility for advanced on-chain functions.
