How ?

Get some ETH Goerli faucet

https://goerlifaucet.com/

Bridge ETH Goerli to BASE Goerli

Generate your Smart Contract with Solidity using OpenZeppelin

1. Change to ERC721 2. Write your Token Name 3. Write the Symbol 4. Put your Base URI (optional) 5. Make it Mintable 6. Copy all code in the black space

Create new file

Create with any name, but it should use .sol extension file. (.sol mean it Solidity file)

Paste your code from step 4.6

Click “Compile <yourfilename.sol>” and wait till success

1. Deploy your Contract

2. Change to “Injected Provider - Metamask” and make sure your Metamask Wallet Connected with Base Goerli Chain RPC

3. Deploy !

Make sure your Base ETH already bridged in your wallet (for paying gas fees). and click “Send Transaction”, then approve it on your wallet

After Success deployed, Copy your Smart Contract (on the left bottom)

Go to Quest Base, Connect your wallet and click continue

Mint your Commemorative NFT

Hola, your NFT have been minted!

StarkDefi is a hub for Defi solutions to be deployed on StarkNet's L2. It will allow for interoperability, scalability, and security via ZK-Rollup without jeopardizing the trustless nature of the Ethereum blockchain. The StarkDefi hub is the gateway to an exciting future for Defi on StarkNet.

Our Offerings

With a wide range of offerings, StarkDefi will be releasing strategically a fully customizable Token Launcher/Mint, to enable easy token creation on the Cairo Language with the click of a button. An AMM and Multisender will then be released to allow for ease of token exchange, transfer and liquidity adding. After our core releases, our staking pool, farm, liquidity locker and launchpad would be released progressively to encompass everything defi on StarkNet.

Why StarkNet?

StarkNet is revolutionary. It basically takes Ethereum and makes it cheaper, creating a wide range of possibilities. It is fast, secure, very scalable and has proven to be limitless, unlike the Ethereum Virtual Machine (EVM). Want to learn more about StarkNet? You can check this out: Starkware

How to testnet ?

• First go to https://testnet.starkdefi.com/#/swap

• Connect your Starknet Wallet. ( Braavos / Argent ) Your wallet must be on the testnet network.

• You will need Goerli ETH for the StarkDefi Testnet. https://faucet.goerli.starknet.io/ If you can't get Goerli ETH, you can bridge https://goerli.starkgate.starknet.io/.

• Select the AMM icon

• Select the pair of tokens that you want to swap

• Enter the amount you want to swap or use the “ % ” icons

• Press the Confirm Swap. Approve the transaction in the pop-up window from your Starknet wallet.

• Your transaction is done!

You can check your transactions from StarkScan. Press the View on Explorer!

Feel free to give feedback on their Discord

     A Blockchain is a collection of records or an electronic database, like a spreadsheet. Blockchains are best known for their crucial role in cryptocurrency systems such as Bitcoin and digital assets such as NFTs, for maintaining a secure and decentralized record of transactions stored in “blocks”, which are distributed across multiple computers. Once each block reaches its storage limit it is “chained” to a block filled previously, and a new block comes into use     

Blockchain Risks?

Lack of Privacy: Although Blockchain technology can ofter a certain degree of privacy. It is not completely private, as transaction data is visible on the network . This means that anyone can view the data, which could lead to privacy concerns.

Regulatory Uncertainty: Blockchain technology is still relatively new and is not yet regulated in many countries. This means that there is a lot of uncertainty about how it should be regulated, which could lead to issues with compliance and legal issues.

Cost: Blockchain technology can be expensive to implement, as it requires substantial resources to maintain and secure the network. This Can be especially true for business that are just getting started in the technology.

Blockchain Benefits?

Security: Blockchain technology is considered to be one of the most secure technologies available. Transactions are validated and encrypted through the use of digital signatures and cryptographic techniques, making it virtually impossible for hackers to gain access to the data.

Transparency: The distributed ledger technology used in Blockchain provides an unprecedented level of transparency. Every transaction is stored on a public ledger, which can be viewed by anyone with access to the blockchain.

How can a business benefit from using Blockchain?

     Blockchain technology offers great business benefits, such as cost savings, through increased speed, efficiency, and automation. It significantly reduces overhead and transaction cost by minimizing or eliminating the need for third parties to verify transactions. Blockchains play a remarkable role in reducing paperwork and human errors

How can I benefit from technology as a creator?

• You own your work and the proof of ownership is stored on the Blockchain and shared with the public.

• You can create and distribute your work without relying on large platforms to promote it, which often charge hefty commissions

• You can Interact with your audience directly, which makes the connection more personal and special.

Through HAVAH's interchain NFT transmission protocol (INTP),

users can bring their NFTs scattered across multiple chains into the HAVAH ecosystem for easier management and utilization.

Let’s take a look at the diagram above. Users who purchase NFTs on their own chains can bring their NFTs onto the HAVAH ecosystem by using the interchain bridge.

By bringing their NFTs onto HAVAH, users get the following benefits.

1. Show off their NFTs from various chains in one place, and browse other users’ NFT collections.

2. Use newly minted NFTs in DApps (as game items, etc).

3. Get a stake in the running of HAVAH by contributing to the ecosystem.

These are the main reasons why we think a user would be motivated to bring their NFTs onto the HAVAH ecosystem, and furthermore, we are preparing a lot of original DApps for you to experience on the platform (which we’ll announce later on).

We still have some major tasks to complete ahead of us, such as…

1. Set up the mainnet blockchain network.

2. Finetune the interchain NFT transmission protocol to bridge NFTs from other chains.

3. Launch a variety of original DApps for users and developers.

All in all, we still have some work cut out for us to create the playground for NFTs that we envisioned.

1. Incentivized Testnet

• Create Havah Wallet (download extension here)

• Go to testnet page

1. Connect with your HAVAH Wallet

2. Submit your e-mail + register an account

3. Claim NFT

   - Mint

   - Bridge

4. Done!

2. Subscribe

3. List your brigded NFT before on Opensea

3rd Hidden Mission :“List Your HAVAH Friends NFT on Opensea”

Tutorials :  Use HAVAH Mitter to bridge HAVAH Friends NFT to the Ethereum chain. Connect your Metamask to Opensea Testnet. (https://testnets.opensea.io/)  Press the [SELL] button on your Opensea profile and list your NFT.

HAVAH Mitter : https://mitter.vega.havah.io/bridge/nft

Note : Only the HAVAH Friends NFT listed from the Ethereum chain will be considered for this mission. If you moved your NFT to a chain other than Ethereum, you can bridge the NFT to the Ethereum chain by selecting the chain you originally sent the NFT to as Source Chain and Ethereum as the Destination Chain.
