Atomic swap exchange client core library

Atomex Client Core library

Atomex is a hybrid exchange based on atomic swap technology and multicurrency HD wallet. This repository contains crossplatform .NET standard Atomex.Client.Core library.

atomex.client.core's Issues

Add xtzToToken / tokenToXtz / tokenToToken methods for light swaps of one chain (or move it into a separate contract)

Collectibles page

Отличие от обычных токенов в том что нужен предпросмотр картинки + на странице токена картинка крупным планом. Balance и amount при отправке это всегда целые числа.

Implement ability for subscription on token transfers

Remove Zeros

Add a refundToAddress method that makes a refund to a different address. The method can only be called by the one who called the initiate (to return the coins directly through the refund)

Add SegWit support

Test Issue #1

Test

Tezos balance is not updated immediately after sending a transaction

Optimize updating balances for all currencies

For some currencies such as USDT, updating balances is slow when there are a large number of transactions. It is necessary to remove unnecessary calls to the database and make the most of the information obtained earlier for optimization. In BTC replace the calculation of the balance for transits with requests to API.

Add User Survey to the website

Migrate from BetterCallDev to Tzkt API

BitcoinBasedSwap does not send a notification about sending a Payment transaction

Use WebSocket.Client library for Bitfinex WebSocket API client

EstimateSwapParamsAsync method when calculating MaxAmount does not take into account that Payment and Redeem can be executed from the same address (for example, XTZ -> TZBTC, ETH -> USDT). Need to deduct Redeem Fee

Fix MarketDataOrderBook synchronization

Wallet is not reporting received and balance.

Add the ability to withdraw coins hanging for a long time (for example, a month) from the contract to the address of the contract creator

Change preview url generation for Tezos contracts and tokens

Create client for TzKT Events

I as developer want to be able to subscribe to TzKT Events so I can implement reactions on this events in different Atomex Clients like Avalonia Desktop client.

Migrate to new TzKT api

Refund can be sended only after median time past for 11 last blocks (BIP-113)

What if I wanted to explore many addresses for other currencies like Tezos and Ethereum.

• My use case is that I have generated many addresses programatically using and I have a mnemonic.

• I use the addresses to receive payments. One address per payment.

• Using your wallet I can see it explores more paths for bitcion so I'm able to see all the addresses that have actually received paymen.t

• But for other currencies like Tezos and Ethereum, I am not able to see for all since it only explores the first two paths for them.

• Is there any settings I can use to modify the number of paths explored

• Or maybe if not could you point me to a part of the code where I can make such changes and use just for my use case.

Thanks.

Insecure secret generation based on current time

https://www.thegeeksearch.com/leap-seconds-in-linux/

Linux handles leap seconds by replaying seconds, not smearing them. Because of that, this has a chance to generate existing secrets on such events.

It also generally can't be guaranteed that clocks are atomically advanced. While C# may offer that guarantee, I do know Rust has specific code in its time handler to ensure only fresh values are returned.

Finally, if more than 1000 swaps are made per second, this will also fail.

Solution to all of the above is a global variable which keeps track of the last used time, compared any freshly grabbed time values to it, and if they're older, uses the latest one plus 1 ms. That said, this will break if you reboot, as you'll lose context on how you're operating with future time values. Saving this value to disk and loading it at the start would work. In order to minimize future drift, you can also differentiate each millisecond with an i value, referring to how many requests were handled for that millisecond. That said, you'll need to save the latest millisecond and the i.

It should not be feasible to exploit either of these due to how there's no nearby leap second and because the initiator generates the secret, meaning any flood (legit or illegitimate) against your servers of swap requests would only put the requester at risk. You would have to run malicious code to take advantage of this under your current setup. That said, this does potentially break the atomic promise of swaps by using known secrets, so it should be fixed.
