The SSVNetwork contract is the main contract for operations and management.

declareOperatorFee(operatorId, operatorFee)Description: Initiates the first step of the operator fee update cycle - declaration of a new fee. After specified time window operator will be able to change to the new fee with executeOperatorFee().
Events:
OperatorFeeDeclared(address indexed owner, uint64 indexed operatorId, uint256 blockNumber, uint256 fee)
executeOperatorFee()Description: Activates operator’s fee change specified in previously called declareOperatorFee(). This function needs to be called within a certain time window following declareOperatorFee().

cancelDeclaredOperatorFee(operatorId)Description: Cancels operator’s fee change requested in previously called declareOperatorFee().

reduceOperatorFee(operatorId, fee)Description: Reduce the operator fee, does not abide by the restrictions of fee increase
Events:
OperatorFeeExecuted(address indexed owner, uint64 indexed operatorId, uint256 blockNumber, uint256 fee)
setFeeRecipientAddress(feeRecipientAddress)Description: sets a fee recipient address to receive tips from user transactions (part block proposal rewards). This address will be set for all the account’s validators (all clusters).
Events:
FeeRecipientAddressUpdated(address indexed owner, address recipientAddress)
registerValidator(publicKey, operatorIds, shares, amount, cluster)Description: Registers new validator to a cluster of provided operators (ids + shares), fails if number of operatorIds is greater than 13..
Events:
ValidatorAdded(address indexed owner, uint64[] operatorIds, bytes publicKey, bytes shares, Cluster cluster)
bulkRegisterValidator(publicKey, operatorIds, shares, amount, cluster)Description: Registers all the new validators provided as argument to a cluster of provided operators (ids + shares), fails if number of operatorIds is greater than 13..
Events:
ValidatorAdded(address indexed owner, uint64[] operatorIds, bytes publicKey, bytes shares, Cluster cluster)
The function emits as many ValidatorAdded events, as is the length of the provided publicKeys array.
Please note: the number of validators that can be registered with thebulkRegisterValidator function is limited by the total transaction size. This depends both on the number of total public keys, as well as the number of operators in the chosen cluster, as follows:
80 validator keyshares for a cluster of 4 operators
40 validator keyshares for a cluster of 7 operators
30 validator keyshares for a cluster of 10 operators
20 validator keyshares for a cluster of 13 operators
removeValidator(publicKey, operatorIds, cluster)Description: Removes validator from the SSV network.
Events:
ValidatorRemoved(address indexed owner, uint64[] operatorIds, bytes publicKey, Cluster cluster)
bulkRemoveValidator(publicKey, operatorIds, cluster)Description: Removes all the validators provided as argument from the SSV network.
Events:
ValidatorRemoved(address indexed owner, uint64[] operatorIds, bytes publicKey, Cluster cluster)
The function emits as many ValidatorRemoved events, as is the length of the provided publicKeys array.
Please note: the number of validators that can be de-registered with thebulkRemoveValidator function is limited by the total transaction size to a maximum of 500 validator keys at a time.
exitValidator(publicKey, operatorIds)Description: Prompts SSV nodes to sign a voluntary exit of the validator.
Events:
ValidatorExited(address indexed owner, uint64[] operatorIds, bytes publicKey)
bulkExitValidator(publicKey, operatorIds)Description: Prompts SSV nodes to sign a voluntary exit for all the validators provided as argument.
Events:
ValidatorExited(address indexed owner, uint64[] operatorIds, bytes publicKey)
The function emits as many ValidatorExited events, as is the length of the provided publicKeys array.
Please note: the number of validators that can be requested to exit from the beacon chain with thebulkExitValidator function is limited by the total transaction size to a maximum of 500 validator keys at a time.
deposit(owner, operatorIds, amount, cluster)Description: Deposits SSV token into a cluster, will fail if not enough tokens are approved.
Events:
ClusterDeposited(address indexed owner, uint64[] operatorIds, uint256 value, Cluster cluster)
withdraw(operatorIds, amount, cluster)Description: Withdraws a specified amount of SSV tokens from cluster of msg.sender, will fail if msg.sender tries to withdraw more than the cluster’s liquidation collateral. To withdraw the entire cluster balance and stop its operation use liquidate().
Events:
ClusterWithdrawn(address indexed owner, uint64[] operatorIds, uint256 value, Cluster cluster)
reactivate(operatorIds, amount, cluster)Description: Reactivates a liquidated cluster, will fail if insufficient SSV tokens to cover the cluster’s liquidation collateral have been deposited.
Events:
ClusterReactivated(address indexed owner, uint64[] operatorIds, Cluster cluster)
Write methods for liquidators
liquidate(owner, operatorIds, cluster)Description: Liquidates a cluster sends their balances to the msg.sender (the Liquidator), will fail if the cluster is not liquidatable (see isLiquidatable()).
Events:
ClusterLiquidated(address indexed owner, uint64[] operatorIds, Cluster cluster)
updateNetworkFee(networkFee)Description: Updates network fee.

Events:
OperatorMaximumFeeUpdated(uint64 maxFee)
updateMinimumLiquidationCollateral(amount)Description: Sets the minimum collateral (in $SSV) each cluster must keep in his balance.
Events:
MinimumLiquidationCollateralUpdated(uint256 value)
updateOperatorFeeIncreaseLimit(newOperatorMaxFeeIncrease)Description: Sets the max amount by which operators can increase fees in each fee update cycle. This does not limit max operator fee, only the rate (%) by which it can be increased within each fee update cycle.
Events:
OperatorFeeIncreaseLimitUpdated(uint64 value)
