| # Bringing Python for Defichain to the next level!🚀🐍 | ||
|
|
||
| Hey to all #Defighters, | ||
|
|
||
| it’s now been 1 year since I started this project and I wanted to give you an update on the current development. | ||
|
|
||
| I first want wo talk about the really exiting stuff!💣 | ||
|
|
||
| ## 1. Integration of Raw Transactions | ||
|
|
||
| I am currently working on the ability to create, sign and broadcast transactions using just python. | ||
|
|
||
| ### What is a raw transaction? | ||
|
|
||
| A raw transaction is a hexadecimal data string and always looks something like this. | ||
|
|
||
| ``` | ||
| 040000000001018605b44cda16f8828a406f4e4377c75b9508930b7cd343729dab1f56fbe19d1d0100000000ffffffff020000000000000000506a | ||
| 4c4d446654787316001404c7767d2009c6dabe47d27a77406141c289376a0000e1f5050000000016001404c7767d2009c6dabe47d27a77406141c2 | ||
| 89376a016300000000000000ffe0f5050000000000fced052a0100000016001404c7767d2009c6dabe47d27a77406141c289376a00024830450221 | ||
| 00b11e61ff38835e09e5f4b4e5417808b99e1ddd3ccf792a60f929db22d3a93a2802203a3a69be756a4451e9461b1d795a13f0c837e104cc708101 | ||
| 7c3dfd844529c21c012103a5c791ba2a9c2668fc10b095e742b971d7acd50ffa77d6b40b9974937cb6064e00000000 | ||
| ``` | ||
|
|
||
| This hexadecimal data string represents a [poolswap transaction](https://defiscan.live/transactions/1fcbdcd1b18753fb24dcaeb259fffeb84123e29e04db688b37522fbe8ce49365?network=TestNet) | ||
| on the blockchain. | ||
|
|
||
| Creating these transactions requires a high level of understanding and can be very complex. | ||
|
|
||
| ### What does the new implementation do? | ||
|
|
||
| The new transaction implementation in the DefichainPython library try’s to enable the user to create these raw | ||
| transaction in a very intuitive and easy way. The goal is that the user can create these transactions like they would | ||
| interact with a full node. | ||
|
|
||
| As an example the creation of a poolswap transaction: | ||
|
|
||
| ``` | ||
| tx = txbuilder.pool.poolswap(addressFrom, tokenFrom, amountFrom, addressTo, tokenTo, maxPrice) | ||
| ``` | ||
|
|
||
| The **tx** variable now contains the fully signed poolswap transaction that can be submitted directly to the blockchain. | ||
| Everything is handled automatically in the background. | ||
|
|
||
| To create a transactions some information from the blockchain is required. The needed information can be retrieved from | ||
| the Ocean API. There is also the possibility to retrieve this information directly from a defichain node or to | ||
| insert this information manually if you want to stay fully offline while creating a transaction. | ||
|
|
||
| ### What does it make so special? | ||
|
|
||
| In the past creation of raw transactions could only be achieved by using the Jellyfish SDK from BirthdayResearch, witch | ||
| is based on Typescript. So anyone who wanted to use python to execute transactions always had to rely on a running node. | ||
| That is now no longer the case! | ||
|
|
||
| Furthermore, I try to make this implementation as user-friendly as possible. So anyone who has worked with a defichain | ||
| node in the past will have no problems getting to know this new way of creating and broadcasting transactions. | ||
|
|
||
| This gives you for example the possibility to automate your lightwallet very easily and without large server costs. | ||
|
|
||
| ### Do you want to test it? | ||
|
|
||
| I have written a [“Basic usage of transactions”](https://docs.defichain-python.de/build/html/additional/basicUsageOfRawTransactions.html#) | ||
| Guide. You can follow this Guide to successfully create and broadcast your first transaction with python. | ||
|
|
||
| But please be careful using it, it’s an MVP and has not been tested extensively. There could still be significant errors | ||
| inside the code that could lead to a total loss of funds. | ||
|
|
||
| I would really appreciate if you could leave some feedback in the comments or per [Twitter](https://twitter.com/Intr0c) | ||
| DM🙂 | ||
| - Did everything work? | ||
| - Is there anything that needs to be improved? | ||
| - How was the User Experience? | ||
|
|
||
| ### Current status of the project | ||
|
|
||
| The current development is an MVP and is still limited in its functionality. All methods will be added, properly | ||
| documented and tested in the next months. | ||
|
|
||
| **What is already implemented?** | ||
|
|
||
| - All needed methods to create and sign native UTXO transactions (for advanced users) | ||
| - This is the base for creating transaction | ||
| - Creating transactions for P2SH and P2WPKH addresses | ||
| - Deserialize almost every raw transaction | ||
| - the corresponding defi transaction must also be implemented | ||
| - UTXO Transactions | ||
| - sendAll (Send all UTXO on an address to specified address) | ||
| - send (Send a specified amount of UTXO to a specified address) | ||
| - Defi Transactions | ||
| - UtxosToAccount | ||
| - AccountToAccount | ||
| - Poolswap | ||
|
|
||
| The current development of transactions can be viewed | ||
| [here](https://github.com/eric-volz/DefichainPython/tree/main/defichain/transactions)! | ||
|
|
||
| **What is planed?** | ||
|
|
||
| 1. Implement all essential defi transactions | ||
| - AccountToUtxos | ||
| - PoolAddLiquidity | ||
| - PoolRemoveLiquidity | ||
| - CompositeSwap | ||
| - DepositToVault | ||
| - WithdrawFromVault | ||
| - ... | ||
| 2. Wallet and Account Encryption | ||
| 3. Logging | ||
| 4. Test and document every essential method | ||
| 5. Adding support for transactions with P2PKH address | ||
| 6. Implement, test and document all remaining defi | ||
| 7. Some special custom transactions?! | ||
|
|
||
| ## 2. Update on my second CFP | ||
|
|
||
| As of the time I submitted my second CFP almost everything I promised was already implemented and ready to use. | ||
|
|
||
| There was just one thing I promised to implement on a later stage. I talked about implementing the API provided by | ||
| the **Defichain Lense** project. This project promised to deliver desperately needed historical data for a tax report | ||
| and also an API to access this historical data. | ||
|
|
||
| As of now this project seems to be not implemented. So accordingly nothing has been built into the library either. | ||
|
|
||
| **Thus, my second CFP has not yet been fulfilled!** | ||
|
|
||
| ### What I will do: | ||
|
|
||
| I will wait until either Defichain Lense launches its service or a different API witch is worth implementing comes | ||
| along. | ||
|
|
||
| If you already have some suggestions which API I should integrate, feel free to comment or write me a DM. | ||
|
|
||
| ## Conclusion | ||
|
|
||
| I hope you got a good overview about the current development. If anything is not clear or if you have some questions, | ||
| don’t hesitate to ask!😉 I am happy about any feedback!🙂 | ||
