Ready to take on the development, but before starting, it is necessary to clarify a few technical points in order to properly assess the scope of work and select the optimal stack.
Create a web application for semi-automatic spread arbitrage between futures on different cryptocurrency exchanges.
The application does NOT search for coins and does NOT scan the market, but only works with those coins that the trader selects manually.
The main task is to provide the user with a trading card, where they can see the price difference between two exchanges in real-time and can open/close positions.

Good day. I already have a ready personal project that corresponds to your idea. However, it does not allow opening and closing positions. Such logic requires the user to provide their API token from the exchange, and very few people would trust that.

Hello!
My name is Alexandra, I specialize in developing real-time web applications, integrations with cryptocurrency exchanges, and creating trading panels for trading and arbitrage.
I am ready to create an application for semi-automatic spread arbitrage between futures in the format you described:
What I will implement:
a trading card that displays the spread between two selected exchanges in real-time;
manual selection of coins by the trader (without market scanning);
display of Bid/Ask prices, funding, percentage differences, calculated profits;
opening/closing positions via exchange APIs (Binance, Bybit, OKX, KuCoin — if needed);
handling API errors, throttling, caching;
secure authorization and key management;
stable operation of WebSocket connections for live data;
My experience:
creating trader panels, signal systems, and bots;
working with futures APIs (Binance Futures, Bybit USDT/Inverse, OKX Swap);
charts, candles, tables, indicators in real-time;
developing tools for arbitrage and spread trading.
I am ready to discuss architecture, technologies, and details in a private chat.
I can start working immediately after clarifying the requirements.
We're building a regulated real estate tokenization platform that converts institutional-grade properties into ERC-3643 security tokens with built-in ONCHAINID compliance. Our platform enables fractional ownership, secondary trading, and DeFi integration—making premium real estate investment accessible to everyone. I am looking for a talented blockchain $ smart contract developer. Tech Stack: - Blockchain: Solidity (ERC-3643 with ONCHAINID) on Arbitrum One, Hardhat - Backend: Node.js/TypeScript, Express, PostgreSQL, Redis - Frontend: React/TypeScript, ethers.js/wagmi, Tailwind - Infrastructure: AWS, Docker, GitHub Actions Blockchain Developer Responsibilities: - Design and deploy ERC-3643 smart contracts with compliance logic - Implement ONCHAINID identity and KYC whitelist integration - Coordinate external security audits and optimize gas usage - Build DeFi lending integrations (staking, yield, collateralization)
We need to connect a payment system to a high-risk site. The main requirements are the acceptance of fiat funds and the withdrawal of funds in cryptocurrency. Preferably no KYC. Only those who have had similar experience. Price is negotiable.
Tech Stack - React: Responsive and dynamic front-end development - Node.js: Robust backend operations - Web3: Multi-chain cryptocurrency integration - Solidity: Smart contract development Project Objective Develop a comprehensive multi-chain staking platform for a popular gaming ecosystem, enabling seamless cryptocurrency interactions, NFT marketplace integration, and enhanced user experience across multiple EVM-compatible blockchain networks.

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.
