To calculate the voting power the user, the function will synchronize its lock position with `VotingEscrow` contract. ## Controller Ballot #### `ControllerBallot.cast(uint256[] weights)` Cast a distribution of the user’s current voting power across all valid Tranchess funds, liquidity pools. and other eligible reward receivers. `weights` is an array of numbers that should sum up to 1e18, representing 100%. To calculate the voting power the user, the function will synchronize its lock position with `VotingEscrow` contract. ## VotingEscrow This contract handles the main logic for creation, redemption and balance calculation of the vote-lock CHESS token `veCHESS`. `vecCHESS` is the governance token in Tranchess ecosystem. Users should lock up their CHESS token for a specified period of time in exchange for `veCHESS`. The balance of `veCHESS` diminishes linearly with respect to time for all users alike. ### Depositing/withdrawing veCHESS #### `VotingEscrow.createLock(uint256 amount, uint256 unlockTime)` Create a vote-lock position of `amount` CHESS expired at `unlockTime`. Note that the `unlockTime` must be at the end of a future week but cannot exceed the maximal allowed lock time `maxTimeAllowed`. #### `VotingEscrow.increaseAmount(address account, uint256 amount)` Increase the number of CHESS of an existing vote-lock position. Note that you cannot call `increaseAmount` upon an expired position; you will have to `withdraw` the previous position and use `createLock` to create a new position. #### `VotingEscrow.increaseUnlockTime(uint256 unlockTime)` Extend the expiration date of an existing vote-lock position. Note that you cannot call `increaseAmount` upon an expired position; you will have to `withdraw` the previous position and use `createLock` to create a new position. #### `VotingEscrow.withdraw()` Withdraw CHESS locked in expired positions. ### veCHESS Crosschain #### `VotingEscrow.veChessCrossChain(uint256 amount, uint256 toChainID)` Transfer `veCHESS` to the `VotingEscrow` on another chain specified by `toChainID` using Multichain’s AnyCall infrastructure. User should pay cross-chain fee in native currency (e.g. ETH on Ethereum) when calling this function. Exact fee amount can be queried from the AnyCall proxy contract, i.e. `IAnyCallV6Proxy(thisContract.anyCallProxy()).calcSrcFees(thisContract, toChainID, 96)`. --- # 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.tranchess.com/tech-support/protocol-overview/governance-and-crosschain.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
