After reading Patrick Anderson's 'Cypherpunk Ethics' we asked ourselves: How do we address the moral hazard of "pricing users out of privacy"?
The dual offering is our attempt at solving this dilemma: free webapp for end users, paid SDK for businesses

MPC ECDSA constructions are remarkably complex and error prone. We investigated them for Sigbash and ultimately decided on MuSig2/Schnorr for simplicity and peace of mind. x.com/arik_g/status/20559616…

This is why bitgo uses MultiSig, not MPC on Bitcoin. On chain multisig is inherently safer than MPC on Bitcoin. Only use TSS or MPC on chains that didn't implement multisig on chain.
