Introduction to MetaMask

We have a thoroughly tested and working smart contract, but until now, we’ve been deploying our contract to Remix’s virtual machine and using the provided virtual Ethereum accounts—a local test network that simulates as much of a real Ethereum network as possible. But still, we have a couple of issues. One, all transactions on the Remix virtual machine are instantaneous, whereas on a real network, we can face delays and slow-speed transactions. A second issue is that this environment is only available to us, and other Ethereum users and accounts can’t access it.
