I just launched a small tool that helps users perform Bitcoin RBF (Replace-By-Fee) transactions. The biggest difference is that it is fully online: no local scripts, no desktop clients, just a web page end-to-end.
You can try it here: https://btc-tools.xyz
I built this because I searched for a long time and mostly found local scripts or client apps. For people who just want to speed up a stuck transaction, that barrier felt too high, so I decided to build one.
What it does
- Take a transaction and build an RBF replacement plan
- Show the full PSBT so you can verify the transaction content
- Sign and broadcast via a browser wallet
Supported wallets
Signing relies on browser extension wallets. Currently supported:
- OKX Wallet
- UniSat
- Bitget Wallet
- Leather
- Xverse
- Magic Eden
Security and verification
The site is not open-source yet, but it displays the full PSBT, and wallets also show transaction details before signing. You can verify inputs, outputs, and fees before approving.
What is next
Right now it only supports RBF. I plan to add more features later, including support for Inscription and Runes.
Feedback welcome
- Please try it and share feedback (flow, UI, prompts, error handling, etc.)
- Let me know what you want to see next
Thanks for checking it out. Link again: https://btc-tools.xyz
