注意：POE给出的解释是： console是新fork一个链出来，所以console中的内容不会被保存，退出就没有了。

想要持久话的话，使用scripts   task(?)

进入： npx hardhat console

转账：

> let accounts = await ethers.getSigners()
undefined
> let sender = accounts[6]
undefined
> let tx = await sender.sendTransaction({ to: '0x948B3c65b89DF0B4894ABE91E6D02FE579834F8F', value: "5000000000000000000" })
> let result = tx.wait()   // 这一步特别重要

> await ethers.provider.getBalance('0x948B3c65b89DF0B4894ABE91E6D02FE579834F8F')
