Providers

<DAppProvider>​

Provides basic services for a DApp. It combines the following components: <ConfigProvider>, <EthersProvider>, <BlockNumberProvider>, <ChainStateProvider> and <ReadOnlyProviderActivator>

Properties:

  • config: Partial<Config>: configuration of the DApp, see Config.

Example:

  import { Mainnet, DAppProvider } from '@usedapp/core'

  const config = {
    readOnlyChainId: Mainnet.chainId,
    readOnlyUrls: {
      [Mainnet.chainId]: `https://mainnet.infura.io/v3/${INFURA_ID}`,
    },
  }

  return (
    <DAppProvider config={config}>
      <App />
    </DAppProvider>
  )

<ConfigProvider>​

Stores configurations and makes them available via useConfig hook.

<EthersProvider>​

Requires: ConfigProvider

<BlockNumberProvider>​

<LocalMulticallProvider>​

Ensures that a multicall contract address is available when developing on a local chain. A multicall contract will be deployed when a multicall address on a local chainId is not defined in the Config.

While the contract is being deployed, a temporary "Deploying multicall..." message will be rendered instead of the user's child components.

<ChainStateProvider>​

<ReadOnlyProviderActivator>​
