The mode the current client is running in fork mode will fetch and cache all state from the block forked from the provided URL normal mode will not fetch any state and will only run the EVM in memory

Example

let client = createMemoryClient()
console.log(client.mode) // 'normal'
client = createMemoryClient({ forkUrl: 'https://mainnet.infura.io/v3/your-api-key' })
console.log(client.mode) // 'fork'
