presaleStaking

Function Type: external
Function Signature: presaleStaking(address,bool,uint256,bytes,uint256,uint256,bool,bytes)
Function Selector: 0x6257deec

The presaleStaking function enables presale participants to stake or unstake their MATE tokens under specific restrictions. This function ensures exclusive access for qualifying presale users while enforcing operational limits.

Restrictions

• Limited to one operation per transaction
• Maximum allocation of 2 staking tokens per user
• Requires active allowPresaleStaking flag
• Not available when allowPublicStaking flag is active (presale users must use publicStaking instead)

Parameters

Parameter	Type	Description
user	address	Presale participant's wallet address
isStaking	bool	true = Stake, false = Unstake
nonce	uint256	Staking contract nonce for replay protection
signature	bytes	User authorization signature
priorityFee_EVVM	uint256	EVVM priority fee
nonce_EVVM	uint256	EVVM payment operation nonce
priorityFlag_EVVM	bool	EVVM execution mode (true = async, false = sync)
signature_EVVM	bytes	EVVM payment authorization

note

• If you want to know more about the signature structure, refer to the Standard Staking/Unstaking Signature Structure.
• The EVVM payment signature (signature_EVVM) follows the Single Payment Signature Structure.

Workflow

The function supports two execution paths:

• Fisher-Mediated: A designated fisher captures the transaction from the fishing spot and submits it to the contract
• Direct User Submission: The user directly submits the transaction to the contract

Staking Process

1. Signature Verification: Validates the authenticity of the user signature
2. Nonce Validation: Confirms the contract nonce is valid and unused
3. Presale Eligibility Check: Verifies presale participation status and token limit compliance
4. Presale Staking Status: Verifies allowPresaleStaking.flag is enabled
5. Process Execution: Calls the internal stakingUserProcess function to handle:
   • Historical record updates
   • Unstaking cooldown management
   • Re-staking restrictions
   • EVVM payment processing
   • Reward distribution
6. Nonce Update: Increments the contract nonce for the user to prevent replay attacks
