Classes

abstractEip1193Provider

Eip1193Provider<API>:

This is an abstract class, which extends Web3BaseProvider class. This class is used to implement a provider that adheres to the EIP-1193 standard for Ethereum providers.

Type parameters

constructor

[symbol]

  • get [symbol](): boolean

  • Returns boolean

asEIP1193Provider

  • Modify the return type of the request method to be fully compatible with EIP-1193

    [deprecated] In the future major releases (&gt;= v5) all providers are supposed to be fully compatible with EIP-1193. So this method will not be needed and would not be available in the future.

    @example
    const provider = new Web3HttpProvider('http://localhost:8545');
    const fullyCompatibleProvider = provider.asEIP1193Provider();
    const result = await fullyCompatibleProvider.request({ method: 'eth_getBalance' });
    console.log(result); // '0x0234c8a3397aab58' or something like that

    Returns Eip1193Compatible<API>

    A new instance of the provider with the request method fully compatible with EIP-1193

abstractSocketProvider

SocketProvider<MessageEvent, CloseEvent, ErrorEvent, API>:

This is an abstract class, which extends Web3BaseProvider class. This class is used to implement a provider that adheres to the EIP-1193 standard for Ethereum providers.

Type parameters

constructor

  • new SocketProvider<MessageEvent, CloseEvent, ErrorEvent, API>(socketPath: string, socketOptions?: unknown, reconnectOptions?: Partial<ReconnectOptions>): SocketProvider<MessageEvent, CloseEvent, ErrorEvent, API>

    • optionalreconnectOptions: Partial<ReconnectOptions>

      The options for the socket reconnection ReconnectOptions

    Returns SocketProvider<MessageEvent, CloseEvent, ErrorEvent, API>

SocketConnection

  • get SocketConnection(): unknown

  • Returns unknown

[symbol]

  • get [symbol](): boolean

  • Returns boolean

asEIP1193Provider
