Custom Testnet Explorer Integration

I have a private blockchain testnet running on a custom chain and I need a full-featured block explorer wired up to it. The goal is simple: once the job is done I want to open a URL and be able to trace every transaction, browse each block, and inspect any smart-contract activity in real time—exactly the way Etherscan does it for Ethereum.

All frontend assets and styling are already sitting in my Git repository, so you can clone the repo and focus on the back-end integration plus any API work needed to make the data flow. If you prefer to replace or tweak parts of the UI you’re welcome, as long as the final look remains consistent with what’s in Git.

What has to work
• Live transaction feed with searchable details (hash, sender, receiver, gas, etc.)
• Block list and individual block pages showing full metadata and decoded logs
• Smart-contract panel displaying source, ABI, and latest state changes
• Automatic sync to the testnet so data stays current without manual refreshes

I’ll give you RPC endpoints, chain specs, and an SSH login to a fresh VPS where the explorer should be deployed. Clean, readable code, clear documentation, and a one-command build or Docker file will be the acceptance criteria.
