publicServiceStaking

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

The publicServiceStaking function allows smart contracts (services) to stake on behalf of users when public staking is enabled. This function includes additional verification to ensure the service address contains contract code.

Parameters

Parameter	Type	Description
user	address	Address of the user who owns the stake
service	address	Address of the smart contract performing the staking
isStaking	bool	true = Stake, false = Unstake
amountOfStaking	uint256	Amount of staking tokens to stake/unstake
nonce	uint256	Unique nonce for this staking operation
signature	bytes	Signature proving authorization for service staking
priorityFee_EVVM	uint256	EVVM priority fee (only for staking)
nonce_EVVM	uint256	EVVM nonce (only for staking)
priorityFlag_EVVM	bool	EVVM priority flag (only for staking)
signature_EVVM	bytes	EVVM signature (only for staking)

note

• If you want to know more about the signature structure for public service staking, refer to the Public Service Staking Signature Structure.
• The EVVM payment signature (signature_EVVM) follows the Single Payment Signature Structure.

Workflow

1. Public Staking Status: Verifies allowPublicStaking.flag is enabled
2. Service Verification: Confirms the service address contains contract code using extcodesize
3. Signature Verification: For staking operations, validates the service staking signature
4. Service Matching: For unstaking operations, ensures service equals user address
5. Nonce Validation: Confirms the contract nonce is valid and unused
6. Process Execution: Calls the internal stakingServiceProcess function
7. Nonce Update: Increments the contract nonce for the user
