Class: WebSocketProvider

A JSON-RPC provider that communicates over WebSocket instead of HTTP.

Supports all the same methods as JsonRpcProvider (getBalance, getBlock, etc.) plus real-time subscriptions via eth_subscribe / eth_unsubscribe.

example

const provider = new WebSocketProvider('wss://eth-mainnet.g.alchemy.com/v2/YOUR_KEY');

// Standard JSON-RPC methods work the same as JsonRpcProvider
const block = await provider.getBlock('latest');

// Real-time subscriptions
const subId = await provider.subscribe('newHeads');
provider.on('block', (blockHeader) => {
  console.log('New block:', blockHeader.number);
});

// Clean up
await provider.unsubscribe(subId);
provider.destroy();

Parameters

Name	Type	Description
`transactionHash`	`string`	the hash of the transaction to get information about

Returns

Promise<TransactionReceipt>

information about the specified transaction that has already been mined

Inherited from

BaseProvider.getTransactionReceipt

Defined in

providers/BaseProvider.ts:243

off

▸ off(event, callback?): WebSocketProvider

Remove an event listener. If no callback is provided, removes all listeners for that event.

Parameters

Name	Type	Description
`event`	`string`	The event name or subscription ID
`callback?`	`Function`	The specific callback to remove, or omit to remove all

Returns

WebSocketProvider

Defined in

providers/WebSocketProvider.ts:330

on

▸ on(event, callback): WebSocketProvider

Event names correspond to subscription types:

'block' → newHeads subscription notifications
'pending' → newPendingTransactions subscription notifications
'logs' → logs subscription notifications
Any subscription ID → direct subscription callbacks

Parameters

Name	Type	Description
`event`	`string`	The event name or subscription ID
`callback`	`Function`	The function to call when the event fires

Returns

WebSocketProvider

Defined in

providers/WebSocketProvider.ts:316

resolveName

▸ resolveName(name): Promise<null | string>

Resolves an ENS name to an Ethereum address.

Performs the full ENS resolution process:

Computes the namehash of the ENS name
Queries the ENS Registry for the resolver contract
Queries the resolver for the address

Identical to ethers.provider.resolveName in ethers.js

example

await provider.resolveName('vitalik.eth');
// '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'

example

await provider.resolveName('thisshouldnotexist12345.eth');
// null

Parameters

Name	Type	Description
`name`	`string`	the ENS name to resolve (e.g. 'vitalik.eth')

Returns

Promise<null | string>

the Ethereum address the name resolves to, or null if not found

Inherited from

BaseProvider.resolveName

Defined in

providers/BaseProvider.ts:629

▸ subscribe(type, params?): Promise<string>

Subscribe to real-time Ethereum events via eth_subscribe.

example

const subId = await provider.subscribe('newHeads');

example

const subId = await provider.subscribe('logs', {
  address: '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2',
  topics: ['0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef'],
});

Parameters

Name	Type	Description
`type`	`SubscriptionType`	The subscription type: `'newHeads'`, `'logs'`, or `'newPendingTransactions'`
`params?`	`object`	Optional parameters (e.g. filter object for `'logs'`)

Returns

Promise<string>

The subscription ID returned by the node

Defined in

providers/WebSocketProvider.ts:254

unsubscribe

▸ unsubscribe(subscriptionId): Promise<boolean>

Unsubscribe from a previously created subscription.

Parameters

Name	Type	Description
`subscriptionId`	`string`	The subscription ID to cancel (returned by subscribe)

Returns

Promise<boolean>

true if successfully unsubscribed, false otherwise
