Hi, and welcome to MetaMask.
Today we’re happy to share our gift to the
The MetaMask browser extension turns Google
Chrome into an Ethereum browser, letting websites
retrieve data from the blockchain, and letting
users securely manage identities and sign
When you start up MetaMask, you are given
a seed phrase that can be used to restore
all the accounts you ever create within MetaMask.
You can switch the current account with the
switch account button in the top right, and
you can add more accounts at the bottom of
the account list.
Your account vault is encrypted and locally
stored within your browser, meaning no account
information ever touches our servers. However,
with your secret phrase, you can easily restore
your vault with the same accounts.
At first glance, Metamask enables you to send
ether like a normal wallet application, but
Metamask’s true strength lies in enabling
your browser to visit Ethereum enabled websites.
Here’s a simple Ethereum distributed app,
or Ðapp, called Tokens, that lets you easily
deploy your own currency.
When you visit a Dapp like Tokens with MetaMask
installed, that website has access to the
Ethereum blockchain via the standard Web3
the blockchain, it asks web3 to send the transaction,
prompting MetaMask to ask for user confirmation.
After you submit a transaction, wait for the
next block for the change to be reflected
on the website…and there it is!
Now I have my own MetaMaskCoins! I can check
my balance or, if I want to send some to another
account, I can click the copy link on it.
I check its balance, see it has none, then
send it some meta-coins!
This has been nice, but it’s all been on
the Morden test net. But with Metamask, I
can always switch what network I’m working
on, say the main network, and I’m ready
issue a token with the full security of the
main Ethereum blockchain.
MetaMask connects to these blockchains with
no synchronization time because we host blockchain
nodes by default. You can always point MetaMask
at your own Ethereum RPC Server, and fully
control your connection to the blockchain.
And that’s how MetaMask lets ordinary websites
talk to a trusted Ethereum provider, all while
letting the user store and manage their own
private keys. We hope this will make it easier
than ever for people to get started creating
and using a new wave of blockchain-enabled
