Upgrade review must include inherited storage and the proxy's exact implementation. Source: [PrimeLeaderboardStorage.sol](https://github.com/VenusProtocol/venus-protocol/blob/v10.3.0/contracts/Tokens/Prime/PrimeLeaderboardStorage.sol). {% endhint %} ## Solidity API ```solidity // Individual deposit record for LIFO tracking (declared in IPrimeLeaderboard) struct Deposit { uint128 amount; // Amount deposited uint64 timestamp; // Deposit timestamp uint64 _reserved; // Reserved for future use } ``` #### BASE\_MULTIPLIER Base multiplier (1.0x) scaled by 1e18 ```solidity uint256 BASE_MULTIPLIER ``` *** #### MAX\_DEPOSITS\_PER\_USER Maximum deposits per user (DoS protection). Constant, set to 30. ```solidity uint256 MAX_DEPOSITS_PER_USER ``` *** #### EXP\_SCALE Scaling factor for calculations (1e18) ```solidity uint256 EXP_SCALE ``` *** #### \_depositStacks User's deposit stack (LIFO order, index 0 = oldest). Holds the `Deposit` records described above. ```solidity mapping(address => IPrimeLeaderboard.Deposit[]) _depositStacks ``` *** #### totalStaked User's total staked XVS ```solidity mapping(address => uint256) totalStaked ``` *** #### \_multiplierDurations Multiplier tier duration thresholds, in seconds. Default `[30 days, 60 days, 90 days]`. ```solidity uint256[] _multiplierDurations ``` *** #### \_multiplierValues Multiplier values corresponding to each tier (scaled by 1e18). Default `[1.3e18, 1.6e18, 2.0e18]`. ```solidity uint256[] _multiplierValues ``` *** #### primeV2 Address of the PrimeV2 contract ```solidity address primeV2 ``` *** #### stakersInitialized Whether staker initialization is complete (prevents further initialization calls) ```solidity bool stakersInitialized ``` *** #### \_\_gap Reserved storage for future upgrades. ```solidity uint256[45] __gap ``` *** --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs-v4.venus.io/technical-reference/reference-core-pool/prime/prime-leaderboard-storage.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
