The write-up
Inspiration
UTXO bloat is a hot topic recently. "Spammers" aren't going away anytime soon, so it's hard to prevent further bloating... but why not incentivize shrinking? Enter Sweepstack, a service allowing people to consolidate their old UTXOs into a single Taproot output with a sponsor paying the miner fees.
As we all know, P2TR outputs are magically more secure than any other type of output, making this a perfect fit for the bitcoin++ hackathon.
What it does
Allows a user to connect a browser wallet, select various UTXOs, then sign a PSBT consolidating those outputs into a single P2TR output with a sponsor paying the fees for them.
- Navigate to a website
- Click 'connect wallet'
- Select UTXOs
- Sign a PSBT
- Transaction fees paid by sponsor
