Methods

publicasEIP1193Provider

• asEIP1193Provider(): Eip1193Compatible<API>

• 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
