DEX

Q: How does Lumino DEX work?

A: We created a series of exhaustive blog posts about Lumino DEX. The trading concepts and technical details can be found on Gitbook & Medium articles.

Q: What is the two-step transaction process?

A: The two-step transaction process separates order matching and execution. This increases transaction speeds and reduces price slippage.

Q: How does the EUTXO model help?

A: The EUTXO model enables advanced smart contract functionality which allows for complex trading strategies.

Q: What is the Dynamic Reverse Mechanism?

A: The Dynamic Reverse Mechanism calculates swap amounts in real-time to avoid overcharging users based on price changes between order and execution.

Q: How does the Dynamic Reverse Mechanism ensure fairness?

A: By recalculating swap amounts at execution, users only pay for the exact tokens received based on latest rates. This prevents overcharging.

Q: Is the smart contract secure? Is there a security audit?

A: Yes - our Smart Contract has been audited by Certik.

Q: I would like to try out the concept without using real ADA. Is there a testnet version?

A: Yes - we are running a developing version of the DEX that is publicly accessible and running on testnet at https://test.d11l7dwmjox0cp.amplifyapp.com/ . Make sure to configure your wallet to operate on Preprod when trying out.

Q: How to trade on Lumino DEX?

A: To start trading on Lumino DEX,

Firstly, you need to have installed a Cardano native wallet.

Secondly,purchase ADA. There has to be some ADA in your Cardano wallet for trading and transaction fee, the amount of ADA is above 4ada + gas fee, due to the UTOX.

Q: What happens to my ADA / tokens when I place a trade?

A: Being a decentralized exchange, Lumino does not hold any assets. Instead, these are stored on the blockchain and protected by a validator script. The assets may only be unlocked if certain conditions are met. These are: a) the trade succeeds, and you get the ordered value, or b) the order is cancelled by you.

Q: What fees are being paid to use the service?

A: There is a 2ADA deposit fee, which is the minimum amount of ADA in any transaction on the Cardano network and will be returned when your orders are processed or cancelled. An additional 2 ADA to pay for the service of MatchMakers to process transactions. So eventually, you need to pay 2ada+gas fee. But your token amount in your wallet should be higher than 4ada plus gas fee to make sure the trading is successfully completed.

Q: Can Lumino access my wallet?

A: No. When you place an order, this is done entirely in your browser and has to be signed by your wallet. We do not receive any data. Note: never share your private keys with anyone!

Q: Are there any risks involved in trading ADA/tokens?

A: As always, investing comes with certain risks. When you buy an asset, its value may increase or decrease over time, which may result in gains or losses. As a rule, never invest more than you are willing to lose.

Q: I have successfully placed an order, but I have not received any tokens, nor does it appear under "My Orders". What should I do?

A: If your order was successful and did not result in any error message, you will soon be able to see it in your transaction history. However, it can take up to a couple of hours until you receive your funds or see your order under "My Orders".

Q:Why did my transaction fail?

A:

1. Insufficient account balance:

Every transaction on Cardano requires a 2 ADA deposit fee and an additional 2 ADA to pay for the services of MatchMakers. If your balance in your wallet is less than 4 ADA plus the gas fee, it will cause the transaction to fail.

2.On-chain transaction failed:

If your previous transaction is still pending and has not been packaged into a block, it might cause the new transaction to fail. In this case, kindly wait a few minutes before starting a new transaction."
