Types
Primary types used in the ZKsync Era
The following section describes key types used in the ZKsync Era. These types facilitate various blockchain operations, such as specifying block ranges, performing withdrawals, and executing transfers.
BlockRange
Represents a range of blocks with the starting and ending block numbers.
type BlockRange struct {
Beginning *big.Int `json:"beginning"` // Starting block number of the range.
End *big.Int `json:"end"` // Ending block number of the range.
}
TransferCallMsg
Contains parameters for transfer call. It can be transformed into ethereum.CallMsg by encoding
the transfer parameters with ToCallMsg method.
type TransferCallMsg struct {
To common.Address // The address of the recipient.
Amount *big.Int // The amount of the token to transfer.
Token common.Address // The address of the token. ETH by default.
From common.Address // The address of the sender.
Gas uint64 // If 0, the call executes with near-infinite gas.
GasPrice *big.Int // Wei <-> gas exchange ratio.
GasFeeCap *big.Int // EIP-1559 fee cap per gas.
GasTipCap *big.Int // EIP-1559 tip per gas.
AccessList types.AccessList // EIP-2930 access list.
}
func (m *TransferCallMsg) ToCallMsg() (*ethereum.CallMsg, error)
WithdrawalCallMsg
Contains parameters for withdrawal call. It can be transformed into an ethereum.CallMsg by
encoding the withdrawal parameters withToCallMsg method.
type WithdrawalCallMsg struct {
To common.Address // The address of the recipient on L1.
Amount *big.Int // The amount of the token to transfer.
Token common.Address // The address of the token. ETH by default.
BridgeAddress *common.Address // The address of the bridge contract to be used.
From common.Address // The address of the sender.
Gas uint64 // If 0, the call executes with near-infinite gas.
GasPrice *big.Int // Wei <-> gas exchange ratio.
GasFeeCap *big.Int // EIP-1559 fee cap per gas.
GasTipCap *big.Int // EIP-1559 tip per gas.
AccessList types.AccessList // EIP-2930 access list.
}
func (m *WithdrawalCallMsg) ToCallMsg(defaultL2Bridge *common.Address) (*ethereum.CallMsg, error)
