Application Project Summary: For example, the "project detector" module scans for new Ethereum projects that are no more than 2 days old and have a liquidity of less than $50. It displays the corresponding projects. (I've already developed 90% of this application, and I will share it with you.) You will need to add the wallet addresses for the "add" and "remove" liquidity transactions to these displayed projects, along with the following transaction. These two wallet addresses should then be saved to the database using the following naming convention: DATE - Token Name In the viewer module, users can enter a token address and see all its transactions, similar to how Dextools displays them (e.g., ...

XRPL DEX EXCHANGE Script - working on XRPL network with XRP I need to build a DEX Exchange based on the concept of XMagnetic or Sologenic, based on the XRPL network in which XRP is my earning benefit. Main features: 1) Listing tokens on xrpl paying a fee in XRP i will decide, or buying the DEX utility token (i will create the token on XRPL and it will be the 1st listed on my dex). 2) Launchpad to let ppl to create tokens based on xrpl with their own AMM liquidity pool 3) Farming area to lock a token to let holders earning benefits in other coins paying a fee buying the dex utility token. 4) AMM area to put funds to work by providing liquidity to a determinate asset. 5) Trade area 6) Swap area and more in the future.

Solana copytrader and frontrun bot Key Points to Verify Detection Before Transaction Completion: The bot must detect the order of the followed wallet before it is completed. If the notification arrives after the transaction is executed, the copy trade should not start. The goal is to capture the order in advance, automatically verify the configured parameters, and only if met, initiate a synchronized purchase. Important Note: If capturing the order before execution is not possible, the bot development will not proceed. Bot Development Methodology Once the ability to detect the order in advance is verified, the bot development should focus on clean code to maximize execution speed. The code structure should be as streamlined and optimized as possible, minimizing latency to execute the ...
