How Does a Multisig Setup Compare to a Single EOA (Externally Owned Account) for Security?
A multisig setup is vastly superior for securing critical functions like contract upgrades. A single EOA is a single point of failure; if the private key is lost or compromised, the contract is at risk.
A multisig requires multiple keys, dramatically increasing the difficulty for an attacker to gain control and providing a buffer against key loss.
Glossar
EOA
Function ⎊ Externally Owned Accounts, or EOAs, represent user-controlled identities within the Ethereum ecosystem, distinguished by possessing a private key enabling transaction initiation and digital signature capabilities.
Multisig Setup
Architecture ⎊ A multisig setup, within cryptocurrency, options trading, and financial derivatives, fundamentally represents a cryptographic protocol requiring multiple private keys to authorize a transaction.
Hardware Wallet Integration
Connection ⎊ Hardware Wallet Integration describes the secure interface protocol that allows software applications or smart contracts to interact with private keys stored within a physically isolated hardware security module for transaction signing.
