Function Type: internal

The presaleClaims function manages presale staking limits and permissions by enforcing the 2 staking token limit for presale users and tracking their staking amounts. This function is called by presaleStaking to validate and update presale user constraints.

Parameters

Parameter	Type	Description
_isStaking	bool	true = Stake (increments count), false = Unstake (decrements count)
_user	address	Address of the presale user

Workflow

The function handles two operation types with different validation flows:

• Staking Operations: Validates limits and increments staking counter
• Unstaking Operations: Validates existing stakes and decrements counter

Staking Process

1. Public Staking Status Check: Verifies allowPublicStaking.flag is disabled, reverts with PresaleStakingDisabled() if public staking is active (presale staking is only valid when public staking is not active)
2. Presale Participant Verification: Confirms the user is registered as a presale participant using userPresaleStaker[_user].isAllow, reverts with UserIsNotPresaleStaker() if not authorized
3. Limit Check: Ensures userPresaleStaker[_user].stakingAmount < 2, reverts with UserPresaleStakerLimitExceeded() if limit reached
4. Counter Increment: Increments userPresaleStaker[_user].stakingAmount++

Unstaking Process

1. Public Staking Status Check: Verifies allowPublicStaking.flag is disabled, reverts with PresaleStakingDisabled() if public staking is active (presale staking is only valid when public staking is not active)
2. Presale Participant Verification: Confirms the user is registered as a presale participant using userPresaleStaker[_user].isAllow, reverts with UserIsNotPresaleStaker() if not authorized
3. Balance Check: Ensures userPresaleStaker[_user].stakingAmount > 0, reverts with UserPresaleStakerLimitExceeded() if no stakes to unstake
4. Counter Decrement: Decrements userPresaleStaker[_user].stakingAmount--
