I have published a project called migrate-wallet. I did this years ago when I wanted to migrate my wallets, but never published it. Now asked GLM to fixed a few things and finish it, so here it is. You can run it offline and it generates 1 transaction per UTXO. if you want to try it. It requires: - UTXO list from Sparrow; - Seed words + optional passphrase; - XPUB of new wallet; Check the readme for instructions and more settings.

Ventoy is a such a nice, simple software for creating a bootable USB stick with multiple ISOs. Just copy the files to the USB stick and it's done.

Fulcrum 2.0 has been released! I synced a new DB from scratch, here's my experience: It took about 2.5 days to sync the new Fulcrum on a laptop (Ryzen 7 5700U, db_mem 8000 GiB). The v2 DB is a little larger than v1: 176 GiB against 166 GiB. To test performance, I repeteadly queried a large BTC address (1HckjUpRGcrrRAtFaaCAUaGjsPx9oYmLaZ) for balance and history and got these results: v1 get_balance: [335, 416] range, avg 378 ms; v2 get_balance: [348, 355] range, avg 352 ms; v1 get_history: [32676, 33723] range, avg 33214 ms; v2 get_history: [23208, 23947] range, avg 23508 ms; Hopefully someone will come up with better benchmarks, it was a real PITA to measure time due to netcat/socat keeping the connection alive. Now, the best part: I left a script running all day, killing -9 Fulcrum and restarting it for a total of 95 kills. The DB was not corrupted. image Check the release notes for instructions on how to upgrade from v1:
