We currently operate a production wallet monitoring dashboard that tracks Ethereum wallets (balances + transactions).
We are looking for an experienced blockchain/backend developer to extend this system to support multiple chains, including:
Bitcoin/TRON/BNB Chain (Optionally others like Polygon, Solana, etc.)
The goal is a single dashboard capable of monitoring multiple wallet types across different chains with reliable, real-time or near-real-time updates.
Scope of Work
Analyze existing ETH wallet monitoring logic Design a multi-chain abstraction layer Implement wallet monitoring for: Balance changes Incoming / outgoing transactions Integrate with reliable RPCs / APIs per chain Normalize data into a common format for the dashboard Ensure scalability (many wallets, frequent polling or streaming)
Technical Expectations
Strong experience with blockchain RPCs & APIs Understanding of: UTXO vs account-based chains Rate limits & batching Webhooks vs polling Experience with at least 2 non-ETH chains
Nice to Have
Prior work on wallet trackers, explorers, or analytics tools Experience with: Blockchair / BlockCypher / TronGrid / Alchemy / QuickNode Knowledge of indexing or event-driven architectures
Deliverables
Multi-chain wallet monitoring logic Chain-agnostic data model Integration guide & setup instructions Test cases or sample monitored wallets
To Apply
Please include: Chains you have worked with APIs / RPC providers you have used A brief explanation of how you would monitor BTC vs ETH wallets
