Hello, I can complete this project using Solana Web3.js. I am waiting for your message to discuss the details.
Hello everyone!
Who can implement tracking of incoming transactions to a Multi Sig Solana wallet
I will describe the task:
We need to create a check for the user's wallet on the front end
1 the user sends us 1 solana to our multi sig wallet
2 Then, he pastes this same wallet (from which he sent us solana) on the front end and clicks the check wallet button
3 we check if investments have been received from this user's wallet to our Multi Sig Wallet. If yes, we return him a response.
Thank you! Your investment of 1 solana has been successfully received!
Who can implement this in the near future? Who knows how to work with solana?

Hello, Dmitry
I can create similar software on node.js as an independent API with dockerization.
Feel free to write, I would be happy to chat.
Budget: 400 USD Deadline: 7 days
I will implement tracking of incoming transactions to a Multi Sig wallet on Solana and verification on the frontend. Mechanics:
Integration with Solana RPC / WebSocket for transaction tracking
Storing expected transactions (1 SOL)
Checking the user's public address — whether a transaction was made to your wallet
Returning status: received / not received
Integration with Metaplex / Solana Web3.js or Anchor is possible
The solution will be secure, without delays, and taking into account the features of Multi Sig wallets.
I can create a demo and adapt it to your frontend.

What needs to be done: conduct an independent expert consultation on the implementation of multisig wallets to protect the company's treasury funds, which operates with high-volume payment processing in USDT across three networks - TRON (TRC20), BNB Smart Chain (BEP20), and Ethereum (ERC20). Requirements: (1) review available market solutions and recommend the optimal one for our profile - a single custodial platform for all three networks or a combination of separate tools for EVM and TRON; (2) propose a signature architecture (e.g., 2-of-3), key distribution among roles, thresholds for quick/large payments; (3) provide recommendations for key storage (hardware wallets, HSM) and procedures in case of key loss or compromise. For whom: the team administering the company's treasury with a high volume of crypto transactions. Success criterion: a ready recommended architecture with a clear implementation plan. Requirements: practical experience in implementing multisig, specifically with TRON (not just EVM), experience with specific solutions (Safe/Gnosis, Fireblocks, BitGo, Cobo, or native TRON multisig), preferably with cases of previous implementations.
Development of a Telegram Mini App (Bot + WebApp) for selling digital goods and in-game currencies (Python / aiogram) Project description: A Telegram bot with a full WebApp interface is required for the automated sale of digital goods (Telegram Stars, Telegram Premium, in-game currencies/donations for PUBG Mobile, Steam, etc.). The project is called Aspect App. The main focus is on speed, smooth UI/UX in a Web3/minimalist style, and complete automation of product delivery after payment. Technology stack: Backend: Python 3.10+, aiogram 3.x (FastAPI for Webhook/API is welcome). Database: PostgreSQL / Redis (for sessions and caching). Frontend (WebApp): React.js / Vue.js / Next.js (at the developer's discretion, speed and smoothness of animations are important). Integrations: Telegram WebApp API. Main functionality (MVP): 1. Client side (Telegram Mini App): Main screen: Product categories (Telegram Assets, In-game Donations). Banner grid for promotions. Product catalog: Product cards with volume selection (e.g., 50, 100, 500 Telegram Stars or UC). Fields for entering player data (Player ID for PUBG). Cart and Checkout: Quick purchase in 2 clicks. Payment module: Integration of payment methods (CryptoBot API / TON Connect / other fiat gateways by agreement). Personal account: Order history, status tracking, referral system (balance within the app). 2. Admin panel (built into WebApp or separate bot): Catalog management (adding/removing products, changing prices). Order monitoring and sales statistics. User database mailing system. 3. Automation logic (A plus): Readiness of the architecture for integration with supplier APIs (API for auto-purchasing Stars/UC). At the MVP stage, some products may be issued with codes from the database. What is required from the contractor: 1. Development of the database and backend architecture in Python. 2. Layout and integration of WebApp (design mockup to be discussed, clean Web3 style, Glassmorphism is important). 3. Setting up secure transactions and payment webhooks. 4. Deployment on the server (Docker, Ubuntu, SSL setup). Candidate requirements: Experience in commercial development of Telegram WebApps for at least 1 year. Portfolio with launched and working Mini Apps (please provide links in your response). Clean, documented code. Working conditions: Work only through the Secure Deal (Safe / Escrow) of the platform. Payment is staged (the project is divided into Sprint 1: Backend + DB, Sprint 2: Frontend WebApp, Sprint 3: Payment integration and testing). Budget: To be discussed with the successful candidate (please indicate your price range and timelines in your response)
