1/ AIRDROP HUNT 🪂

𝗦𝗛𝗔𝗥𝗗𝗘𝗨𝗠 ( 𝗲𝗮𝘀𝘁𝗲𝗿 𝗲𝗴𝗴 🥚)

#Shardeum has recently deployed its Betanet Sphinx

On this occasion we're just going to see how to deploy smart contracts on this Layer
Very few people will do, so that will maybe make difference for an #airdrop

2/ For those who don't know Shardeum yet (come out of your cave 😅) it's an EVM based L1 that uses dynamic state sharding to achieve linearly scalability

For more information :
docs.shardeum.org/Introduction/W…

🪂 Know that 5% of the supply is intended for #airdrops to the community 😏

3/ So let's roll up our sleeves, let's go !

🔸This tutorial takes place on the Sphinx testnet, start by adding this network to your metamask 👇
docs.shardeum.org/network/endpoi…

🔸And claim some testnet $SHM 👇

4/ 𝗘𝗥𝗖𝟮𝟬

To start we gonna deploy an ERC20 Smart Contract 👇

1️⃣ Go to docs.openzeppelin.com/contracts/4.x/…

> select ERC20
> choose a name and symbol for your token
> set an amount in 'premint'
(ex. 1 000 000 000)

When it's done, click on 'Open in Remix' ✅

5/ 2️⃣ On Remix, click 'Compile Contract' button

After compiling:

> go to Deploy & Run Transactions
> ENVIRONMENT > Injected Provider #Metamask ( you should see your own adress if you have done everything right )
> Press DEPLOY ✅

Your smart contract is deployed 🎉

6/ 3️⃣ Now scroll down, under 'Deployed Contracts' :

> click on your contract to open the window

> select 'Transfer', write your own address and amount you want to transfer ( number of tokens doesn't matter, if you 1000 tokens, type 1 and 21 zero like on screenshot below)

7/
> click on 'transact' and
> confirm transaction on your wallet ✅

Congratulations on finishing the ERC20 part 🎉

You can verify that all transactions were successful by pasting your metamask address into the explorer 👇
explorer-sphinx.shardeum.org

8/ 𝗘𝗥𝗖𝟳𝟮𝟭 ( 𝗡𝗙𝗧)

Now second part, we gonna deploy an ERC721 ( NFT) Smart Contract 👇

1️⃣ Return to docs.openzeppelin.com/contracts/4.x/…

> select ERC721
> choose a name and symbol for your token
> now click on 'mintable'

When it's done, Open in Remix ✅

9/ 2️⃣ On Remix, repeat same actions as before to Compile and Deploy your Smart Contract ✅

3️⃣ Now under 'Deployed Contracts' :

> click on your contract to open the window
> select 'Safe mint'
> like before write your own wallet address and the number of NFT to mint (ex.10)

10/ > click on 'transact' and
> confirm transaction on wallet ✅

Congratulations, you have created your ERC721 contract on Shardeum and have just interacted with it 🎉

You can verify to the explorer

11/ Smart Contract part is over 🔥

Don't be fooled, it's very easy to do and only takes a few minutes ⏱️
