presaleStaking

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

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

• Fixed amount of 1 staking token per operation
• 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)

info

For all EVVM testnets allowPublicStaking.flag is enabled by default, all users should use the publicStaking function for staking and unstaking operations.

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 Claims Processing: Calls presaleClaims() to verify presale participation and enforce 2-token limit
4. Presale Staking Status: Verifies allowPresaleStaking.flag is enabled
5. Process Execution: Calls the internal stakingBaseProcess function with:
   • User address and IsAService=false in AccountMetadata
   • Fixed amount of 1 staking token
   • Standard EVVM payment processing
   • Historical record updates and reward distribution
6. Nonce Update: Marks the staking nonce as used to prevent replay attacks

Unstaking Process

1. Signature Verification: Validates the authenticity of the user signature
2. Nonce Validation: Confirms the contract nonce is valid and unused
3. Presale Claims Processing: Calls presaleClaims() to verify presale participation and validate unstaking eligibility
4. Presale Staking Status: Verifies allowPresaleStaking.flag is enabled
5. Process Execution: Calls the internal stakingBaseProcess function with:
   • User address and IsAService=false in AccountMetadata
   • Fixed amount of 1 staking token
   • Standard EVVM payment processing
   • Historical record updates and reward distribution
6. Nonce Update: Marks the staking nonce as used to prevent replay attacks
