The Phantom browser extension and mobile in-app browser are both designed to interact with web applications. EVM web apps can interact with Phantom via the provider that is injected at window.phantom.ethereum. This provider conforms to the EIP-1193 standard and is also injected at window.ethereum to support legacy integrations. Phantom also supports EIP-6963 for ease of integration.
