Smart Contract Bug Fix & Optimization (BNB & USDT Refunds + Node Stability)
Budget: $30 – $250 SGD
#### **Description:**
We need an experienced **Blockchain Developer** to review and optimize our smart contract on the Binance Smart Chain (BSC). Your primary task is to ensure transactions do not fail due to gas fee issues, implement an automatic retry mechanism, and refund users in case of repeated failures.

#### **Deliverables:**
1. **Bug Fixing & Gas Optimization:**
- Optimize gas fees to **prevent failed transactions**.
- Ensure cost-efficient execution.
2. **Failed Transaction Handling:**
- **Retry the transaction** automatically if it fails.
- If the transaction fails again, **process refunds** for:
- **BNB:** $2.00 equivalent.
- **USDT:** 0.4% of loan fees.
3. **Node Connection Stability:**
- Implement **continuous connection** using a **stable node provider** (Alchemy is unreliable).
- Recommended providers:
- **Ankr** – Affordable and scalable.
- **GetBlock** – Full/archive nodes with unlimited requests.
- **QuickNode** – Low latency with WebSocket support.
4. **Integration & Testing:**
- Ensure the changes are properly implemented and tested in a live environment.
- Provide a **detailed report** on the optimizations, fixes, and refund logic execution.

#### **Skills Required:**
✅ Solidity
✅ Binance Smart Chain (BSC)
✅ Web3.js / Ethers.js
✅ Gas Optimization
✅ Smart Contract Auditing
✅ Node Infrastructure Management
#### **How to Apply:**
- Share **relevant past projects** with similar functionality.
- Provide a **brief plan** on how you’ll address the issues.
- Mention which **node provider** you suggest and why.
