Use MPC to sign transactions without ever constructing a private key

Sign transactions without generating, using or re-assembling a private key

MPC provides the accessibility of Hot Wallet with the security of Cold Storage

Eliminate the trade-off between:

  • ● Cold Storage which is secure but slow
  • ● Hot Wallets which are fast but vulnerable
