(Total Marks: 100) Practical Ethereum Tasks [20%]
This assignment will also partly act as a check to see if you have completed the various tasks in
each of the lectures on the Sepolia Ethereum testnet.
It will also act as an unofficial “participation” mark. If you attended lectures and followed the
exercises, then many of these tasks will be easy – you will have already completed a lot of this
assignment.
Make sure that you perform ALL tasks using ONE Ethereum address that’s been
registered at finscrypto.xyz/faucet.
(25 Marks) Part A – Sepolia Testnet Chain

(5 marks) Task A6
Investigate and discover the unique identifier IDs (number between 0-9999) for the following
Milady Maker & Pudgy Penguin NFTs:
(5 marks) Task A7
There exists a Uniswap V2 liquidity pool consisting of 800,000,000 “King of Tariffs” (KOT) tokens
in conjunction with 4,000 ETH. Assume that the KOT token contract has 18 decimal places.
Assuming the pool charges 0% trading fees, if you were to exchange 40 ETH, how much
quantity of KOT tokens would you receive? Give your answer to the nearest 2 decimal places.
(5 marks) Task A8
● The Gulf of America Dollar token ($GALD) has a total supply of 50,000,000.
● There exists a Uniswap V2 liquidity pair, GALD/ETH, that consists of 500 ETH and
40,000,000 $GALD.
● The market capitalization of $GALD (denominated in USD) is calculated by multiplying
the total supply by the going exchange rate within the pool. So, $625,000 to begin with.
● An aggressive buyer comes along and starts exchanging ETH for $GALD.
Assume there are no swap fees, the price of 1 ETH remains at $1,000 USD indefinitely, and that
there are no other buyers/sellers.
What is the minimum quantity of ETH that the buyer would need to swap to $GALD via the
liquidity pool in order to push the market capitalisation to $1 billion USD? Give your answer to
the nearest 2 decimal places.
(35 Marks) Part B – Sepolia Testnet Chain (Extended)
Make sure that you perform ALL tasks using ONE Ethereum address that’s been
registered at finscrypto.xyz/faucet. Read Task B8 before beginning this section.
(5 marks) Task B1
● Create your own token on the Sepolia testnet blockchain, giving it an interesting name
and ticker. The supply of the token should be the first 4 digits of your zID. We will deduct
marks for boring names.
● Now “verify the contract” on Etherscan. Explain what this means.
(2.5 marks) Task B2
Send exactly 25% of the total supply to my Ethereum address
(0x7c29eed8ed02194c3aba4f1e8abb87e680000000).
(5 marks) Task B3
Create a new Uniswap V3 liquidity pool with the following pair, containing a minimum of 100
AUD:
● $AUD
● $YOUR TOKEN
Make a post on the Moodle course forum that advertises that your token is live and available to
trade via Uniswap to your fellow students. Your post should contain:
- Your Token smart contract address
- V3 Uniswap pool smart contract address
- Initial price ratio of the pool
Example of a good submission:
“

LIVE for trading ™ at [0xxxxxxxx(V3 UniSwap pool/NFT smart contract

(40 Marks) Part C – Base Chain
Make sure that you perform ALL tasks in this section using the SAME Ethereum address
that’s been registered at finscrypto.xyz/faucet. Note: It is possible to have the same address
across different blockchains, provided they are compatible with the Ethereum Virtual Machine.
(5 marks) Task C1
Swap some of your ETH for USDC on Aerodrome: (https://aerodrome.finance)
Note: do not swap all of your ETH, leave some in your wallet (over half, or 0.00025) to pay for
gas in the subsequent activities.
(5 marks) Task C2
Supply USDC to Aave on the Base market instance via (app.aave.com) and then borrow some
EURC. You should end up with at least these positions:
● Lend/Supply some USDC
● Borrow some EURC
(5 marks) Task C3
Engineer a debt position on AAVE in which your USDC exposure is greater than the total
amount of USDC you originally obtained in the swap performed in Task C1. Please ensure your
health factor is not low enough that you will get liquidated in the next few weeks.
(5 marks) Task C4
Calculate your running P&L in USD for your debt position. Consider your Supply rate, offset
against your borrow rate (and any additional incentives). Provide workings. Additionally, identify
a better opportunity (or the next best), ignoring any hedging or risk considerations.

Bridge at least 0.00014 of Ether (not the supply ETH) to the Optimism chain (5 marks).
Use the Stargate Bridge [https://stargate.finance/bridge] (you may need to select a fast transfer)
Another alternative is Relay [https://relay.link/bridge] (Minimum 0.00005ETH)
(10 marks) Task C6
Using Optimism, find a way to convert your Optimism ETH to Sepolia ETH (Hint: There is a
bridge available for this purpose). Provide the transaction hash on the originating chain (this
should be on the Optimism network). Calculate the actual USD price of Sepolia ETH at the time
of your trade and explain in a maximum of 3 sentences why there is a market for Sepolia ETH.
(10 marks)
(5 marks) Task C7
Provide your private key if you think it’s a good idea.
