Entertainment Contracts
This type of contract has a unique characteristic where the balance gradually increases with an increase in the number of participants. However, after a specific duration, there is a sudden outflow of Ether, leading to a substantial reduction in the balance, which stabilizes at a particular amount, or may even drop to zero, occurring at regular intervals. The reason for this is that there will be a winner in the game, and the contract will send the balance to the winner as the prize money, so the outflow value of the contract will be much greater than the inflow value, while for most of the time, the addition of participants will cause the inflow value to be greater than the outflow value. However, this phenomenon is not common in other types of contracts.
Social Contracts
This type of contract exhibits the following two characteristics: (i) any user can only send transactions, but not receive them. (ii) the Ether inflow value for any user is 0. In social contracts, users primarily perform actions such as registering accounts, submitting information, or voting in a polling contract. Therefore, these contracts only require incoming transactions and do not involve outgoing transactions. When users register or submit information, they do not transfer Ether; instead, they only pay a gas fee to ensure contract execution, resulting in the contract balance always being zero.
Gambling Contracts
The focus of this study is on gambling contracts characterized by brief trading durations, including lotteries, slot machines, coin tosses, and dice rolls. However, gambling contracts with longer time horizons, such as soccer, horse racing, and boxing, are excluded from consideration. All of these gambling activities share a common characteristic: players either lose all their wagers or win a predetermined percentage of the prize money in a single wager. For instance, if a player wagers A Ether on a dice roll and emerges victorious, they receive a bonus amounting to x times their initial stake (assuming no additional fees). This bonus can be calculated as Y = Ax - Ay% after accounting for the commission rate of y%. To differentiate gambling contracts from insurance contracts, the transaction duration feature becomes crucial. This feature is determined by calculating the difference between the timestamp when the user receives the outcome of the gamble (regardless of winning or losing the prize) and the timestamp when the user places the bet on the contract. Since gambling contracts typically have shorter transaction durations, any contracts with a duration of less than or equal to 1 day are categorized as gambling contracts, whereas contracts with durations exceeding 1 day are classified as insurance contracts.
Insurance Contracts
Both insurance contracts and gambling contracts share similarities in how users deposit and withdraw funds. Specifically, there are two possible scenarios when the user deposits funds into the contract: (i) when the insurance is not in effect or when the gambling does not result in a win and no payout is given, or (ii) when the insurance is active or when the gambling results in a win and a payout is issued. Nonetheless, there exists a significant difference between these two categories of contracts regarding the duration of the trade. Even the fastest insurance contracts require at least one day for the participant to receive the premium, while short-term gambling contracts typically yield results and payout winnings immediately after the user places a bet. As a result, insurance contracts must meet both essential criteria: (i) the inflow and outflow of Ether for users must be proportional, or alternatively, only inflow without outflow is allowed; (ii) the transaction duration (calculated as the difference between when the user receives the insurance payout and when the user sends the insurance money to the contract) should exceed one day.
Finance Contracts
Using a securities trading contract as an illustration, the decentralized nature of a smart contract enables it to function as an intermediary for securities transactions. Once the user selects the contract, they can promptly execute the designated transaction. After accepting the trade declaration, the trading contract matches and executes trades based on the order fulfillment rules. Trades that meet the fulfillment conditions proceed, while those that do not await fulfillment. Orders that exceed the commission time limit will be unsuccessful. This particular contract solely facilitates incoming transactions and does not support outgoing transactions. Upon matching the order's fulfillment rules, the transaction is deemed successful, and the contract transfers the user's funds to the respective buyer, thereby concluding the transaction. Consequently, any Ether entering the contract must exit the contract within the same day. This contract must satisfy both essential characteristics: (i) users can only submit incoming transactions, not outgoing ones; and (ii) the contract experiences equal inflows and outflows of Ether within a designated day.

Case Study: Preventing Reentrancy in Financial Lending
Description: GaGAT successfully identified a critical reentrancy flaw in a financial lending contract, enabling precise remediation and preventing potential asset siphoning.
Problem: A financial lending contract's core transfer function was vulnerable to reentrancy. Attackers could repeatedly trigger fund transfers via recursive calls before balance deduction, siphoning assets.
GaGAT's Role: GaGAT's in-depth graph analysis and global feature integration precisely highlighted the reentrancy pattern, including the invocation of recipient's fallback function prior to balance deduction.
Solution & Impact: By reordering the balance deduction to occur before the external call, the vulnerability was eliminated. Subsequent GaGAT re-evaluation confirmed 'no reentrancy vulnerability' classification, ensuring contract integrity and user asset security.
