Getting started with Solana

Hello !

I've recently Started Learning WEB3 from MetaCrafters.io

Join Me and millions of other aspiring web3 developers in your learning journey.

This repo contains everything that I've learnt so far (including assignments and challenges.)

Alright Let's get Started.

Fork this repo and clone it in your local system.

    git clone <repo-link>

    cd <cloned-repo-directory>

install all the dependencies

    npm install 

All done! run node index.js in your terminal .

   node index .js

This will create a new key-pair for your very first web3 Account/Wallet.

And additionally it will Airdrop 2-SOL in your wallet.

Note: This is just test SOL, only good enough for testing.

Also, If you run node index.js again it'll create a new key value pair corresponding to a new account/Wallet.

See this example highlighted public-key in the below img,

You'll find a similar newly generated public key in your terminal output. Copy this public key.

Challenge-1

Run the following command to check wallet balance and Air-drop additional SOL into your existing wallet/Account.

    node challenge1.js <previously-copied-public-key>

Here we've Air-dropped 1 SOL into the existing wallet as can be seen in the output.

Note: 1 Lamport = 0.000000001 SOL

You Should get an output as shown below...

Challenge-2

Remember we generated a key-pair using index.js, Let's call it Sender's key-pair or wallet/account.

scroll back to the output and copy the secret key.

You should find the secret key in an array format as shown -

copy this secret key array and paste it in challenge2.js line - 13 under the variable name Demo_secretKey

Now run,

node reciever.js

The above command will create another key-pair for a new Wallet/account where we can send SOL from senders's Account and hence, complete a transaction. Let's call this newly created account Reciever's Wallet/account.

Copy the public key and paste it in the challenge2.js file line - 42 under the varaible name reciever_publickey.

That's about it!

You're Done..

Run the Following command -

node challenge2.js

and you've successfully completed a transaction between sender and reciever's account. You should get an output like -

Using the transaction Signature we find in the output, we can check the transaction detials here.
