Type parameters

Type parameterValue
A extends any[]any[]
IBaseContract

​
Constructors

​
new ContractFactory()

new ContractFactory<A, I>(
   abi, 
   bytecode, 
   runner?, 
IPFSHash?): ContractFactory<A, I>
Create a new ContractFactory with abi and bytecode, optionally connected to runner. The bytecode may be the bytecode property within the standard Solidity JSON output.

​
Parameters

ParameterTypeDefault value
abiInterface | InterfaceAbiundefined
bytecodeBytesLike | { "object": string; }undefined
runner?null | ContractRunnerundefined
IPFSHash?null | stringnull

​
Returns

ContractFactory<A, I>

​
Properties

PropertyModifierTypeDescription
bytecodereadonlystringThe Contract deployment bytecode. Often called the initcode.
interfacereadonlyInterfaceThe Contract Interface.
runnerreadonlynull | ContractRunnerThe ContractRunner to deploy the Contract as.

​
Methods

​
connect()

connect(runner): ContractFactory<A, I>
Return a new ContractFactory with the same ABI and bytecode, but connected to runner.

​
Parameters

ParameterTypeDescription
runnernull | ContractRunnerThe runner to connect to.

​
Returns

ContractFactory<A, I> A new ContractFactory.

​
deploy()

deploy(...args): Promise<BaseContract & {
  "deploymentTransaction": ContractTransactionResponse;
} & Omit<I, keyof BaseContract>>
Resolves to the Contract deployed by passing args into the constructor. This will resovle to the Contract before it has been deployed to the network, so the baseContract.waitForDeployment should be used before sending any transactions to it.

​
Parameters

ParameterTypeDescription
…argsContractMethodArgs<A>The arguments to the constructor.

​
Returns

Promise<BaseContract & { "deploymentTransaction": ContractTransactionResponse; } & Omit<I, keyof BaseContract>> A promise resolving to the Contract.

​
getDeployTransaction()

getDeployTransaction(...args): Promise<ContractDeployTransaction>
Resolves to the transaction to deploy the contract, passing args into the constructor.

​
Parameters

ParameterTypeDescription
…argsContractMethodArgs<A>The arguments to the constructor.

​
Returns

Promise<ContractDeployTransaction> A promise resolving to the deployment transaction.
