Using the Lightning Anchor Fee Bumping Service: A Frontend Walkthrough

Welcome to Part 6 of my Lightning Anchor Fee Outputs Series In the previous articles, we built the entire backend for a Lightning powered CPFP fee bumping service. From Bitcoin RPC integration, to LND invoice creation, to broadcasting the child transaction. In this final part, I will walk you through the frontend and show you exactly how to use the service end to end. What the Service Does When a Bitcoin transaction gets stuck in the mempool due to low fees, you can use Child-Pays-For-Parent (CPFP) to accelerate/unstuck it. Our service uses the anchor output as the input for a child transaction that pays a higher fee. You pay for this service via a Lightning invoice, and the service broadcasts the fee-bumping transaction on your behalf. Prerequisites Before using the frontend, make sure the following are running: Docker containers: bitcoin-regtest, lnd-alice, postgres-db, redis-cache Backend server on port 3000 (npm run dev in /backend) Frontend on port 5173 (npm run dev in /frontend)
