### Ethereum Provider | [**EIP-1193**](https://eips.ethereum.org/EIPS/eip-1193)

The Ethereum Provider acts as a bridge for Web3 libraries designed for EVM chains, such as [EthersJS](https://eips.ethereum.org/EIPS/eip-1193) and [Web3JS](https://docs.web3js.org/guides/web3_providers_guide/#injected-provider). For example, integrating Tweed with a dApp built using EthersJS is straightforward and requires only three lines of code.\
implements the `chainChanged` functionality to support the EVMs that are supported by the tweed infrastructure.
