publicStaking

Function Type: external
Function Signature: publicStaking(address,bool,uint256,uint256,bytes,uint256,uint256,bool,bytes)
Function Selector: 0x21cc1749

The publicStaking function enables universal access to MATE token staking when the allowPublicStaking.flag is enabled, regardless of presale participation status or account type.

info

For all EVVM testnets allowPublicStaking.flag is enabled by default.

Parameters

Parameter	Type	Description
user	address	User address
isStaking	bool	true = Stake, false = Unstake
amountOfStaking	uint256	Amount of staking tokens to stake/unstake
nonce	uint256	Staking contract nonce for replay protection
signature	bytes	Staking contract signature for replay protection
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. Feature Status Verification: Confirms allowPublicStaking.flag is enabled
2. Signature Verification: Validates the authenticity of the user signature
3. Nonce Validation: Confirms the contract nonce is valid and unused
4. Process Execution: Calls the internal stakingBaseProcess function with:
   • User address and IsAService=false in AccountMetadata
   • Specified amount of staking tokens
   • Standard EVVM payment processing
   • Historical record updates and reward distribution
5. Nonce Update: Marks the staking nonce as used to prevent replay attacks

Unstaking Process
