Sigbash is now live on mainnet and fee to use.
You may recall that arbedout released a signet version in February (#1430263).
Sigbash is a cryptographic co-signing service for Bitcoin that enables policy-based spending controls that keep transaction and policy details private.
You define spending policies (approval workflows, vendor whitelists, rate limits, etc.), and we cryptographically verify policy satisfaction while remaining blind to transaction amounts, recipients, or policy details. Institutional-grade policy enforcement meets self-custody privacy.
The website has an interesting ai tool that creates a wallet policy for you based on your needs.
Here is arbedout's announcement on X:
It looks like they removed the concrete use cases from the earlier version. I hope they add them back because otherwise the viewer is left to imagine the potential and it's not obvious.
