BaseDeployer - ZKsync Docs

The BaseDeployer facilitates the deployment of smart contracts and smart accounts on the ZKsync Era network. It provides methods to deploy contracts using both the CREATE and CREATE2 methods, ensuring flexibility and security in contract deployment.

`Init`

Creates an instance of BaseDeployer based on provided AdapterL2.

func NewBaseDeployer(adapter *AdapterL2) *BaseDeployer

`Deploy`

Deploys smart contract using CREATE2 method.

Inputs

Parameter	Type	Description
`auth`	`*TransactOpts` (optional)	Transaction options.
`tx`	`Create2Transaction`	CREATE2 transaction parameters.

Deploy(auth *TransactOpts, tx Create2Transaction) (common.Hash, error)

Example

bytecode, err := os.ReadFile("Storage.zbin")
if err != nil {
 log.Panic(err)
}

//Deploy smart contract
hash, err := wallet.Deploy(nil, accounts.Create2Transaction{Bytecode: bytecode})
if err != nil {
 panic(err)
}
fmt.Println("Transaction: ", hash)

`DeployAccount`

Deploys smart account using CREATE2 method.

Inputs

Parameter	Type	Description
`auth`	`*TransactOpts` (optional)	Transaction options.
`tx`	`Create2Transaction`	CREATE2 transaction parameters.

DeployAccount(auth *TransactOpts, tx Create2Transaction) (common.Hash, error)

Example

# Crown token on testnet
TokenAddress := common.HexToAddress("0x927488F48ffbc32112F1fF721759649A89721F8F")

_, paymasterAbi, bytecode, err := utils.ReadStandardJson("Paymaster.json")
if err != nil {
 log.Panic(err)
}

// Encode paymaster constructor
constructor, err := paymasterAbi.Pack("", common.HexToAddress(TokenAddress))
if err != nil {
 log.Panic(err)
}

// Deploy paymaster contract
hash, err := wallet.DeployAccount(nil, accounts.Create2Transaction{Bytecode: bytecode, Calldata: constructor})
if err != nil {
 log.Panic(err)
}
if err != nil {
 log.Panic(err)
}
fmt.Println("Transaction: ", hash)

`DeployAccountWithCreate`

Deploys smart account using CREATE method.

Inputs

Parameter	Type	Description
`auth`	`*TransactOpts` (optional)	Transaction options.
`tx`	`CreateTransaction`	CREATE transaction parameters.

DeployAccountWithCreate(auth *TransactOpts, tx CreateTransaction) (common.Hash, error)

Example

# Crown token on testnet
TokenAddress := common.HexToAddress("0x927488F48ffbc32112F1fF721759649A89721F8F")

_, paymasterAbi, bytecode, err := utils.ReadStandardJson("Paymaster.json")
if err != nil {
 log.Panic(err)
}

constructor, err := paymasterAbi.Pack("", common.HexToAddress(TokenAddress))
if err != nil {
 log.Panic(err)
}

// Deploy paymaster contract
hash, err := wallet.DeployAccountWithCreate(nil, accounts.CreateTransaction{
 Bytecode: bytecode,
 Calldata: constructor,
})
if err != nil {
 log.Panic(err)
}
fmt.Println("Transaction: ", hash)

`DeployWithCreate`

Deploys smart contract using CREATE method.

Inputs

Parameter	Type	Description
`auth`	`*TransactOpts` (optional)	Transaction options.
`tx`	`CreateTransaction`	CREATE transaction parameters.

DeployWithCreate(auth *TransactOpts, tx CreateTransaction) (common.Hash, error)

Example

bytecode, err := os.ReadFile("Storage.zbin")
if err != nil {
 log.Panic(err)
}

//Deploy smart contract
hash, err := wallet.DeployWithCreate(nil, accounts.CreateTransaction{Bytecode: bytecode})
if err != nil {
 panic(err)
}
fmt.Println("Transaction: ", hash)

Signer

Handles transaction signing for ZKsync

Wallet

Unified interface for managing accounts
