AEREDIUM launches AERSeal to end single-key control of smart contracts

AEREDIUM has launched AERSeal, a security product for smart contracts. It exists to stop a single compromised private key from handing an attacker control of a contract.

Smart contracts often rely on one private key to authorise sensitive operations. Those include minting assets, upgrading the contract, or changing administrative settings. If someone steals that key, they may be able to take control. If the key goes missing, the organisation could permanently lose access to those functions.

AERSeal replaces this single point of failure with a threshold signing system. It runs on AERKey, AEREDIUM’s key infrastructure.

Rather than storing a complete private key in one location, the system divides control across multiple key shares. Each share sits in a separate hardware-attested enclave. The system never reconstructs the full key. Instead, the shares collectively produce signatures using the CGGMP24 threshold signing protocol.
