TLC Interface (v1)

TLC token interface

Methods

allowance

function allowance(address owner, address spender) external view returns (uint256)

Returns the remaining number of tokens that spender will be allowed to spend on behalf of owner through {transferFrom}. This is zero by default. This value changes when {approve} or {transferFrom} are called.

Parameters

Name	Type	Description
owner	address	undefined
spender	address	undefined

Returns

Name	Type	Description
_0	uint256	undefined

approve

function approve(address spender, uint256 amount) external nonpayable returns (bool)

Sets amount as the allowance of spender over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 Emits an {Approval} event.

Parameters

Name	Type	Description
spender	address	undefined
amount	uint256	undefined

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
