I need a seasoned blockchain developer who can jump in right now and finish a full integration with the ZEC blockchain within the next 24 hours. The target is a running web application that also relies on its own backend/database, so you will be wiring both layers to the blockchain and handing back a working, fully tested build. Scope • Connect my existing web front-end to ZEC so transactions post and confirm in real time. • Sync the app’s current database records with on-chain data, keeping both sides consistent. • Provide a quick walk-through (video or call) and concise deployment notes so I can reproduce the setup. Fixed budget is ₹10,000 and the clock starts the moment you accept. Please respond only if you have proven ZEC (or similar UTXO-based) experience...

I need a Flash-style TRC20 token built on the Tron blockchain that is both burnable and protected by multi-signature access. My priority is to have the contract coded, fully tested, and ready for deployment as quickly as possible without compromising security or adherence to the official TRC20 standard. Please write the contract in Solidity, comment it clearly, and supply a brief README so I can redeploy or verify it myself later. A small, self-contained test script (TronBox, Hardhat, or a comparable framework) that proves the burn function and the multi-sig requirement are working will speed up my review. Deliverables: • Auditable Solidity source code implementing TRC20 with burnable capability and multi-sig control • Compiled bytecode, ABI, and deployment steps • A s...
