BTCPay Server has supported multisig wallets for a while, but version 2.1.0 brings a complete redesign of the user experience and introduces powerful new features aimed at improving security, collaboration, and flexibility.
Collaborative custody: Create wallets that require multiple signatures to authorize a transaction.
Self-hosted multisig coordination: Keep control of your company’s public keys and signing flow without relying on a third-party.
Hardware wallet support: Works seamlessly with the BTCPay Vault and is compatible with majority hardware signing devices.
Notification system: Stay informed with email alerts when transactions are created, pending, (requiring sufficient amount of signatures), and broadcasted.
Integration with plugins: Works with Vendor Pay and future features, enabling multisig-based payouts. Integrates with Xpub Extractor, allowing all multisig participants to easily get appropriate format
Whether you're managing company funds, implementing shared custody, or simply want more control, the new multisig experience is built to scale with your needs.
