TLCV1

Alluvial Finance Inc.

TLC (v1)

The TLC token has a max supply of 1,000,000,000 and 18 decimal places.Upon deployment, all minted tokens are send to account provided at construction, in charge of creating the vesting schedulesThe contract is based on ERC20Votes by OpenZeppelin. Users need to delegate their voting power to someone or themselves to be able to vote.The contract contains vesting logics allowing vested users to still be able to delegate their voting power while their tokens are held in an escrow

createVestingSchedule

function createVestingSchedule(uint64 _start, uint32 _cliffDuration, uint32 _duration, uint32 _periodDuration, uint32 _lockDuration, bool _revocable, uint256 _amount, address _beneficiary, address _delegatee, bool _ignoreGlobalUnlockSchedule) external nonpayable returns (uint256)

Creates a new vesting scheduleThere may delay between the time a user should start vesting tokens and the time the vesting schedule is actually created on the contract.Typically a user joins the Liquid Collective but some weeks pass before the user gets all legal agreements in place and signed for thetoken grant emission to happen. In this case, the vesting schedule created for the token grant would start on the join date which is in the past.

As vesting schedules can be created in the past, this means that you should be careful when creating a vesting schedule and what duration parametersyou use as this contract would allow creating a vesting schedule in the past and even a vesting schedule that has already ended.

Parameters

Name	Type	Description
_start	uint64	start time of the vesting
_cliffDuration	uint32	duration to vesting cliff (in seconds)
_duration	uint32	total vesting schedule duration after which all tokens are vested (in seconds)
_periodDuration	uint32	duration of a period after which new tokens unlock (in seconds)
_lockDuration	uint32	duration during which tokens are locked (in seconds)
_revocable	bool	whether the vesting schedule is revocable or not
_amount	uint256	amount of token attributed by the vesting schedule
_beneficiary	address	address of the beneficiary of the tokens
_delegatee	address	address to delegate escrow voting power to
_ignoreGlobalUnlockSchedule	bool	whether the vesting schedule should ignore the global lock

Returns

Name	Type	Description
_0	uint256	index of the created vesting schedule

decimals

function decimals() external view returns (uint8)

Returns the number of decimals used to get its user representation. For example, if decimals equals 2, a balance of 505 tokens should be displayed to a user as 5.05 (505 / 10 ** 2). Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei. This is the default value returned by this function, unless it's overridden. NOTE: This information is only used for display purposes: it in no way affects any of the arithmetic of the contract, including {IERC20-balanceOf} and {IERC20-transfer}.

Returns

Name	Type	Description
