Contract

The class designed to interact with smart contracts on the Ethereum blockchain.

Type parameters

Name	Type
`Abi`	extends `ContractAbi`

Hierarchy

Web3Context<EthExecutionAPI, typeof contractSubscriptions>

↳ Contract

Implements

Web3EventEmitter<ContractEventEmitterInterface<Abi>>

Constructors

constructor

• new Contract<Abi>(jsonInterface, context?, returnFormat?): Contract<Abi>

Creates a new contract instance with all its methods and events defined in its ABI provided.

new web3.eth.Contract(jsonInterface[, address][, options])

Type parameters

Name	Type
`Abi`	extends readonly `AbiFragment`[]

Parameters

Name	Type	Description
`jsonInterface`	`Abi`	The JSON interface for the contract to instantiate.
`context?`	`Web3Context`<`unknown`, `any`> \| `Partial`<`Web3ContextInitOptions`<`EthExecutionAPI`, { `logs`: typeof `LogsSubscription` ; `newBlockHeaders`: typeof `NewHeadsSubscription` ; `newHeads`: typeof `NewHeadsSubscription` }>>	The context of the contract used for customizing the behavior of the contract.
`returnFormat?`	`DataFormat`	-

Returns

Contract<Abi>

The contract instance with all its methods and events.

Example
var myContract = new web3.eth.Contract([...], '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe', {
  from: '0x1234567890123456789012345678901234567891', // default from address
  gasPrice: '20000000000' // default gas price in wei, 20 gwei in this case
});

To use the type safe interface for these contracts you have to include the ABI definitions in your Typescript project and then declare these as const.

Example
const myContractAbi = [....] as const; // ABI definitions
const myContract = new web3.eth.Contract(myContractAbi, '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe');

methods

• get methods(): ContractMethodsInterface<Abi>

Creates a transaction object for that method, which then can be called, send, estimated, createAccessList , or ABI encoded.

The methods of this smart contract are available through:

The name: myContract.methods.myMethod(123) The name with parameters: myContract.methods['myMethod(uint256)'](123) The signature myContract.methods['0x58cf5f10'](123)

This allows calling functions with same name but different parameters from the JavaScript contract object.

> The method signature does not provide a type safe interface, so we recommend to use method name instead.

// calling a method
const result = await myContract.methods.myMethod(123).call({from: '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe'});

// or sending and using a promise
const receipt = await myContract.methods.myMethod(123).send({from: '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe'});

// or sending and using the events
const sendObject = myContract.methods.myMethod(123).send({from: '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe'});
sendObject.on('transactionHash', function(hash){
  ...
});
sendObject.on('receipt', function(receipt){
  ...
});
sendObject.on('confirmation', function(confirmationNumber, receipt){
  ...
});
sendObject.on('error', function(error, receipt) {
  ...
