Desig is a blockchain-agnostic multisig solution. It employs multi-party computation (MPC) technology and remove the need of smartcontract solution. Desig divides the master key into shares and gives each signer a share to keep. When someone proposes a transaction, each signer will use their key shares to approve or reject. If Desig collects enough approvals, the key shares will be combined into a valid master key. This way, even if one signer’s key share is compromised, the attacker won't be able to recreate the whole master key.
