Course Prerequisites

This course is targeted at intermediate Solidity developers. Of course, if this is not you, you can still take this course but you may not fully follow as there is some assumed knowledge including:

• What a blockchain is
• What a zero-knowledge proof is
• Merkle Trees
• Understand hash functions and how they can be used for commitments
• What a nullifier is
• How state works on Ethereum
• EVM smart contract development preferred

If you would prefer, you can watch the following courses (for free) on Cyfrin Updraft to get up to speed beforehand:

• Blockchain Basics
• Solidity
• Foundry Beginner
• Foundry Advanced

Deployment Steps

1. Get an RPC endpoint

export NODE_URL=https://rpc.testnet.aztec-labs.com

2. Create but don't deploy a CLI wallet

aztec-wallet create-account -a main --register-only --node-url $NODE_URL

Note the output

3. Get some fee juice on testnet from GregoJuice bridge

4. Deploy your account

aztec-wallet deploy-account accounts:main --payment method=fee_juice --node-url $NODE_URL

5. Deploy the contract e.g., token contract

aztec-wallet deploy --node-url $NODE_URL --from accounts:main --payment method=fee_juice --alias token private_token@Token --args accounts:main Token TOK 18

6. Interact with the contract

aztec-wallet send mint_to_public --node-url $NODE_URL --from accounts:main --payment method=fee_juice --contract-address token --args accounts:main 100

7. Simulate to read state

aztec-wallet simulate balance_of_public --node-url $NODE_URL --from accounts:main --contract-address token --args accounts:main

Section 0

This section is just a welcome to the course

• Meet the instructor
• What you will learn
• What are the prerequisites

Section 1

What is Aztec and how does it work?

• Account abstraction refresher video
• 45 min course on zero-knowledge proofs
• What is alpha

Section 2

Build a private counter smart contract. Code

• Modular arithmetic
• Finite fields refresher video
• Grego Juice Bridge to get fee juice on Testnet

Section 3

Thank you

I just wanted to say a massive thank you to the following people:

• The entire Aztec team for making this possible (namely Nico, Grego, Jan, Maddiaa, Niall and Alejo for answering millions of questions)
• Jess for her help with editing (she is awesome)
• Patrick Collins for supporting me in creating long form content (the structure is inspired by courses from Cyfrin Updraft)
• Josh: devrel at Aztec for his fab AI resources and docs
• The Wonderland team for their learning resources and codebase I modified :)
