Hi @everyone - thanks for sticking around!

I know it's been a while since the last project update (sorry!). Unfortunately, I've come to realize that the ecosystem is a little bit too young for most projects, including yakuSwap. That being said, Chia's potential is huge and the community is awesome. I'm working on a new, probably more useful project: [GreenWeb.js](https://github.com/Yakuhito/GreenWeb.js).

The goal of GreenWeb.js is to be Chia's equivalent of web3.js - developers will be able to include a javascript file on their site and then get data from the Chia blockchain. The project is still young and, at the time of writing this message, still has an SSL-related issue that prevents it from working. However, I'm confident that I'll find a way around it (probably with the help of someone else) and that we'll see web apps using GreenWeb.js in the future.

In other news, the #gm channel is now open. Please only use it to say 'gm' - any other thing will get you kicked!

If you have any questions, don't hesitate to use #general.

Atomic cross-chain swaps for Chia and its forks.

This repository only holds the source of the UI client. The server application can be found in the yakuSwap-server repository and the Ethereum contract can be found in the yakuSwap-eth repository.

Releases

YouTube Demo Trade (older version)

It's faster: There's no need to search for an escrow! A yakuSwap trade has 100 blocks (31.25 minutes) to succeed. If anything goes wrong, you'll get your money back in 150 blocks (~47 minutes) from the original transaction.

It's cheaper: The total swap fee doesn't exceed 0.75% of the transacted amount.

It's safer: It's always safer to trust nobody rather than somebody. With yakuSwap, you don't need to trust anyone - escrows, intermediaries, exchanges or trade partners - since your money is handled by smart contracts.

You're going to need a fully synced node for each currency involved in a swap. If you want to trade Ethereum, make sure you have enought ETH in your MetaMask wallet to pay for the transaction (100000 gas is enough). Download the latest version of yakuSwap from the releases page of this project on the same computer the nodes are running on and extract the zip file. Start the application and then navigate to http://localhost:4143.

After conecting with a trade partner via the Discord bot, copy the given string to your clipboard. Open yakuSwap, navigate to the 'Trades' tab, and click on the 'Add new trade' button. Click on 'Import' to load the trade from your clipboard. After clicking 'save', click on the trade to start it (the newest trade is usually at the bottom of the list).

You can now follow the intructions on screen. You and your partner will make one transaction each for fork trades. After seeing 'Done! Check your wallet :)' or 'Done' and using the wallet to confirm that you have successfully received your coins (you might have to wait a minute for the transaction to be included in a block), you can safely delete the trade.

Please note that the server creates a new log file for each trade. If anything unexpected happens with one of your trades, its log file will be useful in restoring your coins. However, the log also contains sensitive data, so please only share it with trusted people.

It's a way of exchanging two cryptocurrencies without a trusted third party.

I'm Mihai, but I usually go by the username yakuhito. Here's my Twitter profile and here's my LinkedIn page.

Solidity is trickier than it first seemed. The current contract needs to undergo further testing and modifications before it can be deployed on mainnet. Thank you for your patience!

I have a few theories, but I cannot give a definitive answer. All binaries were built using GitHub Actions from the public source code, which you can find in my repositories - if you don't want to trust me, just read the code and compile the binaries yourself.

If the total time required to make a trade is higher than 30-40 minutes, I highly recommend cancelling it by closing the client and the server, waiting one hour and then opening the trade - that doesn't mean your partner had malicious intentions, though. Please keep in mind that your coins will get unlocked one hour after they were initially locked.

If your trade gets cancelled for any reason, your coins will be locked for a certain period of time. For most currencies, that period is 192 blocks from the moment the contract was issued (about 1 hour). This long period was chosen in order to prevent a certain kind of attack against the swap.

You can PM/DM me about it, but my response time tends to be very high. I strongly recommend using the app's Import/Export functionality to distribute your currency - that way, users can add your coin with a few clicks!

You don't have to - you can always modify the source of the exchange contract and remove the fee. However, the 0.7% fee motivates me to continue supporting this project (which was developed in my free time), so I'd really appreciate if you don't.

No problem! Just join the official Discord server and ask them :)

Thank you to everyone using this software and special thank you to everyone paying the fee!
