Functions

MIN_STAKE_DURATION

function MIN_STAKE_DURATION() external returns (uint256 duration);

MAX_STAKE_DURATION

function MAX_STAKE_DURATION() external returns (uint256 duration);

YEAR_BASE

function YEAR_BASE() external returns (uint256);

baseToken

This function retrieves the address of the ERC20 token used as the base token for staking and rewards.

function baseToken() external returns (IERC20);

Returns

startTimestamp

This function retrieves the starting timestamp. This may be used for reward calculations or other time-based logic.

function startTimestamp() external returns (uint256 timestamp);

getLockup

This function retrieves the details of a specific lockup for a given staker and lockup index.

function getLockup(address staker, uint256 index) external view returns (Lockup memory lockup);

Parameters

Returns

lockupCount

This function retrieves the total number of lockups associated with a specific staker.

function lockupCount(address staker) external view returns (uint256 count);

Parameters

Returns

previewVotes

This function simulates a lockup scenario, providing details about the resulting lockup structure for a specified amount and duration.

function previewVotes(uint128 amount, uint256 duration) external view returns (Lockup memory lockup);

Parameters

Returns

approveExtender

This function grants approval for a designated extender contract to manage a specific lockup on behalf of the staker.

function approveExtender(address extender, uint256 lockupId) external;

Parameters

revokeExtender

This function revokes approval previously granted to an extender contract for managing a specific lockup.

function revokeExtender(address extender, uint256 lockupId) external;

Parameters

isApprovedExtender

This function checks whether a specific account has been approved by a staker to manage a particular lockup through an extender contract.

function isApprovedExtender(address account, address extender, uint256 lockupId) external view returns (bool);

Parameters

Returns

extendForSender

This function extends the lockup period for the caller (msg.sender) for a specified lockup ID, adding a new duration and amount.

function extendForSender(uint256 lockupId, uint256 duration, uint128 amount)
    external
    returns (Lockup memory newLockup);

Parameters

Returns

extendForAccount

This function extends the lockup period for a specified account, adding a new duration and amount. The caller (msg.sender) must be authorized to manage the lockup through an extender contract.

function extendForAccount(address account, uint256 lockupId, uint256 duration, uint128 amount)
    external
    returns (Lockup memory newLockup);

Parameters

Returns

merge

This function merges multiple lockups associated with the caller (msg.sender) into a single new lockup.

function merge(uint256[] memory lockupIds) external returns (Lockup memory newLockup);

Parameters

Returns

unstake

This function unstakes the specified lockup ID for the caller (msg.sender), returning the details of the unstaked lockup.

function unstake(uint256 lockupId, address to) external returns (Lockup memory lockup);

Parameters

Returns

unstakeToSender

This function is a simplified version of unstake that automatically sends the unstaked tokens to the caller (msg.sender).

function unstakeToSender(uint256 lockupId) external returns (Lockup memory lockup);

Parameters

Returns

stakeToSender

This function stakes a specified amount of tokens for the caller (msg.sender) for a defined duration.

function stakeToSender(uint128 amount, uint256 duration) external returns (Lockup memory lockup);

Parameters

Returns

stake

This function stakes a specified amount of tokens for a defined duration, allowing the caller (msg.sender) to specify an optional recipient for the staked tokens.

function stake(uint128 amount, uint256 duration, address to) external returns (Lockup memory);

Parameters

Returns

incentiveTotals

This function retrieves the total incentive information for a specific ERC-20 token.

function incentiveTotals(IERC20 token) external view returns (TokenIncentiveTotals memory);

Parameters

Returns

incentiveBatchCount

This function retrieves the total number of created incentive batches.

function incentiveBatchCount() external view returns (uint256);

Returns

claimInformation

This function retrieves claim information for a specific account and incentive batch index.

function claimInformation(address account, uint256 batchIndex) external view returns (ClaimInformation memory info);

Parameters

Returns

claimFromIncentiveBatchAndExtend

This function allows claiming rewards from a specific incentive batch while simultaneously extending a lockup with the claimed tokens.

function claimFromIncentiveBatchAndExtend(uint256 batchIndex, uint256 lockupId)
    external
    returns (Lockup memory lockup, uint128 claimAmount);

Parameters

Returns

claimFromIncentiveBatch

This function allows claiming rewards from a specific incentive batch, without extending any lockups.

function claimFromIncentiveBatch(uint256 batchIndex) external returns (Lockup memory lockup, uint128 claimAmount);

Parameters

Returns

createIncentiveBatch

This function creates a new incentive batch for a specified amount of incentive tokens, timepoint, stake duration, and associated ERC-20 token. An incentive batch is a reward of incentives put up by the caller at a certain timepoint. The incentive batch is claimable by ve holders after the timepoint has passed. The ve holders will receive their incentive pro rata of their vote balance (pastbalanceOf) at that timepoint. The incentivizer can specify that users have to stake the resulting incentive for a given stakeDuration number of seconds. stakeDuration can either be zero, meaning that no staking is required on redemption, or can be a number between MIN_STAKE_DURATION() and MAX_STAKE_DURATION().

function createIncentiveBatch(uint128 amount, uint48 timepoint, uint128 stakeDuration, IERC20 incentiveToken)
    external
    returns (uint256 index);

Parameters

Returns

Stake

event Stake(address indexed user, uint256 lockupId, Lockup);
