What is the main goal of the ERC-4337 standard, which implements Account Abstraction (AA)?
- To allow wallets to function as smart contracts, increasing their functionality and security without needing to change the main Ethereum protocol
- To completely replace EOA accounts with a new account type on the Ethereum network
- To lower transaction fees by 90% through a new data compression system
- To introduce a new token for gas fees that will replace ETH
Correct

- EIP-4337
- ERC-4337
- ERC-4338
- EIP-4338

Question 3 of 10

3. Question
What does the ERC-4337 standard enable?
- Configuration of a wallet using a seed phrase
- Storage and transfer of assets for EOA wallets only
- Combines the functions of third-party accounts (EOAs) and smart contract accounts, allowing wallets to be managed by smart contract accounts
- Integration with other ERC standards, such as ERC-20 and ERC-721
Correct

Incorrect
Question 4 of 10

4. Question
What are smart contract audits?
- A process of verifying the code exclusively for its performance
- A thorough analysis of the source code to find security vulnerabilities, logical errors, and inefficient fragments
- An automated scan of the contract to look for typos
- A formality required to publish a contract, with no impact on security
Correct

Incorrect
Question 5 of 10

5. Question
How does an AirGapped wallet work?
- By connecting to the Internet via an Ethernet cable
- By connecting to a Wi-Fi network
- By isolating the device from an untrusted network, removing all network interfaces
- By using only Bluetooth data transmission
Correct

Incorrect
Question 6 of 10

6. Question
What is Proto-Danksharding (EIP-4844)?
- It is a comprehensive audit system for smart contracts
- It is the first step toward full sharding in Ethereum, introducing a new type of transaction with additional data fragments
- It is a new standard for encrypting data on the Ethereum network
- It is a tool to counter DDoS attacks on the Ethereum network
Correct

Incorrect
Question 7 of 10

7. Question
How does decentralized storage work?
- Data is stored only on one central server
- Data is stored only on a computer cloud
- Files are stored on multiple computers, and access to them is secured by encryption and splitting the data into fragments
- Files are stored in the cloud, but can only be accessed by one company
Correct

Incorrect
Question 8 of 10

8. Question
What should you do if an error occurs and cryptocurrencies are sent to the wrong address or network?
- Panic and take no action
- Remain calm and analyze the situation
- Ignore the problem because the cryptocurrency cannot be recovered
- Change the password for the cryptocurrency wallet
Correct

Incorrect
Question 9 of 10

9. Question
How does Threshold Signature Scheme technology work?
- It relies on one person to sign documents
- It involves dispersing the generation of keys and signatures among multiple users
- Uses only public keys to verify the signature
- Has no application in banking or finance
Correct

Incorrect
Question 10 of 10

10. Question
What is the main advantage of threshold signatures (Threshold Signature Scheme)?
- They require large amounts of data, which makes them slower than standard transactions
- They provide increased security by dispersing private keys
- Are less efficient than other key management systems
- They do not allow easy addition of new members to the signing group
Correct

Incorrect
