Hey everyone, maker here. I started this because I wanted a Litecoin multisig vault for my own savings and every option I found was either a desktop app that hadn't been updated in years, or required me to juggle xpub files between cosigners by hand. Nothing felt like something I'd trust a family member to actually use. LiteSig does the coordination part for you: cosigners just open a link, add their key in their own browser, and the vault assembles itself. I never see a private key, not even for a second, the server only stores encrypted blobs. You can try the whole multisig flow free on testnet before putting a single real coin behind it. Just open sourced the crypto core too (key derivation, address generation, PSBT signing) so anyone who knows this stuff can check my work instead of trusting me blindly. Happy to answer anything, especially if you've tried setting up multisig before and it put you off. That friction is exactly what I'm trying to fix.
