Counterparty RiskThe risk that one party to a financial transaction defaults or fails to meet its contractual obligations, causing a financial loss to the other.
Manual AuditA review of contract code, design, and deployment by experts to identify security risks and assess overall security.
Traditional NFTA token usually minted on a smart-contract blockchain to represent a digital item and potentially link to off-chain metadata.

Short PositionA contract position taken when a trader expects the underlying asset's price to fall.

Rollover CostCosts that may arise when switching to a new contract after a futures contract expires; over the long term, they may erode the returns of products employing futures strategies.
Bollinger Band SqueezeA condition in which the upper and lower bands contract tightly, indicating currently low volatility and potentially foreshadowing increased volatility, but not the direction of price movement.
Formal VerificationA method that represents contract logic and expected behavior as mathematical statements and uses automated tools to check whether they match.

Perpetual contractA derivative contract with no expiration date that can be held continuously, using a funding rate mechanism to help 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; it is one of the main factors used to calculate the funding rate.
Gas FeeThe transaction fee required to execute an EVM transaction; its amount may vary depending on contract complexity and network activity.
