|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a web page, `connectToMetaMask.html` that :
|
||
|
|
|
||
|
|
- Loads an ethereum JavaScript Library. It should be the only JavaScript library.
|
||
|
|
- Contains a `Connect` button that triggers metamask to ask the user to connect an account.
|
||
|
|
- Once connected, the page displays :
|
||
|
|
- the address of the account
|
||
|
|
- the balance of this account
|
||
|
|
- Contains a button `Refresh balance` that refreshes the balance.

**Note on vocabulary** :
|
||
|
|
|
||
|
|
A **wallet** is an object or a software that contains private keys and allows the user to sign them.
|
||
|
|
An **account** is, on Ethereum, a particular address with an associated private key.
|
||
|
|
|
||
|
|
Most **wallets**, like MetaMask, can manage several **accounts**, often stemming from the same cryptographic **seed**. However, please be aware that some software use interchangeably accounts and wallets.
