TradFiUsed to refer to a category of perpetual contracts that track the prices of traditional financial assets such as equities, commodities, and foreign exchange.
TradFi perpetual contractsTracking stocks,ETF commodities or indices, and other traditional financial assets, but without conferring ownership of the underlying assets, are perpetual contracts.
U-Margined ContractsU-margined contracts are a contract type supported by this derivatives skill. Related interfaces can be used to query market data, trade, and manage positions.

child chainsA smaller chain built on top of the main chain that can run customized smart contracts and process specific tasks according to predefined rules.
smart contract security auditA security audit targeting specific risks in deployed smart contract code.

Manual auditThe process in which experts review contract code, design, and deployment to identify security risks and assess the overall security status.
Ethereum Virtual Machine (EVM)The computational core of the Ethereum ecosystem, it is a Turing-complete programmable machine responsible for decoding bytecode and executing smart contracts.
Traditional NFTTokens typically minted on smart contract-enabled blockchains to represent digital items and potentially link to off-chain metadata.
Going LongA trader establishes a corresponding directional position in a contract in anticipation of the underlying asset’s price rising.
Short SellingA trader establishes a corresponding-direction contract position in anticipation of the underlying asset’s price falling.
Cross margin modeA mode that considers the assets and multiple positions in a derivatives account together when calculating margin and liquidation risk.
Atomic swapA technology that uses smart contracts to directly exchange two cryptocurrencies without relying on centralized intermediaries such as exchanges.
Decentralized exchange platform (DEX）A platform that operates using blockchain smart contracts and generally allows users to trade directly from their own wallets.
Decentralized application (DApp)An application that runs on blockchain and smart contracts, which can be used to build user-facing AI agent services.

Hedge liquidationEstablishing an equal-sized contract in the opposite direction to offset the existing futures position.
Rollover costThe cost that may arise when replacing an expiring futures contract with a new contract, which may erode the returns of products using futures strategies over the long term.
Formal verificationA verification method that expresses contract logic and expected behavior as mathematical statements and uses automated tools to check whether they are consistent.
AuthorizationPermission allowing another entity or contract to perform specified operations; the scope and authorized party must be reviewed.
Data LayerAn architectural layer responsible for organizing and storing blockchain state, transaction details, and smart contract data.
Smart contractA program that executes according to network rules and may contain vulnerabilities, upgrade privileges, and external dependencies.
Smart Contract LayerThe architectural layer responsible for smart contract automation, verification, and execution.
Smart contract parallelizationExecuting multiple smart contracts simultaneously to improve the performance, scalability, and responsiveness of decentralized applications.
Smart contract walletA cryptocurrency wallet that uses programmable smart contracts to set transaction rules, execute operations automatically, and configure security measures.
Smart contract issueSecurity issues arising from errors, hacking attacks, or other vulnerabilities in smart contracts, which may result in users losing funds.
Futures ETFthat does not directly hold the underlying asset, but uses futures contracts to gain exposure to the relevant asset ETF。
Futures ContractA standardized derivatives contract under which both parties agree to buy or sell a specified quantity of an asset at a predetermined price on a specified future date.
Leverage ETF Perpetual contractA derivative contract with no expiration date that tracks leveraged ETF prices and does not represent ownership of actual ETF units.
Model checkingA method for verifying whether a contract satisfies the expected specifications by examining the states and behavior of a formal model.
Bitcoin futures ETFInvest in Bitcoin futures contracts to gain indirect exposure to future Bitcoin price movements through the futures market.
Perpetual ContractA derivative contract with no expiration date, designed for continuous holding, whose funding rate mechanism helps keep its price close to that of the underlying asset.
Premium IndexAn indicator reflecting the difference between a contract price and the spot price of the corresponding asset; one of the main factors in calculating the funding rate.
Gas feesExecute EVM The transaction fee required for the transaction, the amount of which may vary depending on contract complexity and network activity.
