CLI Script for Automated Solana Transfers via Coinbase API & Excel Input

CLI Script for Automated Solana Transfers via Coinbase API & Excel Input Job Description Overview We are looking for an experienced backend developer to create a lightweight, command-line interface (CLI) script that automates cryptocurrency withdrawals using the Coinbase API. The script will run locally on Windows/Mac via CMD/Terminal. It must be designed to dynamically pull all authentication data and transaction instructions directly from a local spreadsheet or Excel file ( .xlsx or .csv ). Key Requirements & Constraints • Excel / Spreadsheet Integration: The script must natively parse a local spreadsheet file to securely extract: ◦ My Coinbase API credentials (API Key and Secret). ◦ The three designated target wallet addresses and their specific transfer amounts. • Network Constraint: All transactions must occur strictly over the Solana network. The script must be explicitly configured to handle native SOL or Solana-based asset withdrawals via the Coinbase Advanced Trade API. • CLI Automation: A lightweight execution script (Python or Node.js) that can be triggered seamlessly via the command line (CMD). • Error Handling & Reporting: The script must provide real-time console feedback during execution, log successful transaction signatures, and include strict error-checking to prevent partial or duplicate asset distributions. Project Scope & Deliverables This is a fixed-price, one-off project. The job will be considered 100% complete when: • The script successfully parses the API keys and destination data directly from the provided Excel/ spreadsheet format. The script confirms the automated transfers natively over the Solana network into all three designated wallet addresses. • Clean, well-documented source code is delivered alongside a brief setup guide and a spreadsheet template detailing exactly how the columns must be structured. • The developer successfully makes the automated transactions using a provided sample Coinbase api to provided wallet adresses. Otherwise the contract is nullified. • the code provides full report as to initial balance, transaction outcome, final balance and full error report if there is. Required Skills • Proven experience working with the Coinbase API / Coinbase Developer Platform. • Proficiency in Python (using libraries like pandas or openpyxl ) or Node.js (using libraries like exceljs ). • Solid understanding of the Solana network environment and transfer routing protocols. • Commitment to security best practices regarding local credential encryption and handling. Budget & Timeline • Budget: $100 (Fixed-price) • Timeline: Project to be completed within 3–5 days of official hiring.
