Soapbox Signer 0.4.1
This release introduces Bitcoin transaction signing, persistent activity logs, and a number of reliability fixes since 0.2.3.
New: Bitcoin / Taproot transaction signing
- Sign Bitcoin PSBTs directly from web apps via window.nostr.signPsbt, including BIP-375 silent payments.
- Before signing, the approval popup shows a Transaction Details panel — recipients, amounts, total sent, and the network fee — so you can see exactly what you're authorizing. The raw transaction is also available under "Info for nerds."
- If a transaction can't be decoded, you get an explicit blind-signing warning instead of a misleadingly "safe"-looking prompt.
- Every Bitcoin transaction requires its own approval. Unlike other permissions, transaction signing can never be granted standing access to a site — there's no way for a site to sign repeatedly without prompting you each time.
New: Activity logs
- Structured, persistent logging across the extension to help with troubleshooting.
- A new panel in the options page lets you choose a log level, view the entry count, export logs as JSONL, and clear them.
Fixes & improvements
- The welcome / onboarding screen now opens reliably on a fresh install.
- Only a single welcome window opens when no identity is configured, instead of stacking up duplicates.
- Resolved a Firefox warning about an unexpected property in the extension manifest.
- Improved compatibility of the Nostr provider when injected into pages.Source code released under MIT License

- You can now configure your profile relays by installing the native connector.
