AEREDIUM has launched AERSeal, its first end-to-end product built with AERKey, to reduce reliance on a single private key for privileged smart-contract functions such as upgrades, token minting and other administrative actions. The product uses CGGMP24 threshold ECDSA signing, with key shares stored separately in hardware-attested enclaves and combined to produce signatures without reconstructing a conventional private key. Organizations can require an M-of-N group approval process using passkeys before an action proceeds. AERSeal works with existing contracts on Ethereum Virtual Machine and EVM-compatible networks, but customers must transfer relevant ownership, minting or upgrade authorities to the threshold-controlled address before activation. The system verifies those transfers onchain and allows customers to independently verify key assignment through address derivation and a freshly signed challenge, including offline. Onboarding includes KYC or KYB checks, contract registration, cryptographic verification, privilege transfer and policy configuration. The launch comes amid broader industry concern about single-key risks, including a roughly $700,000 loss from a Polymarket operations wallet in May that the platform attributed to a private-key compromise. AERSeal is part of AEREDIUM’s AER360 product family and is provided by Aeredium Network LLC. The company disclosed no named customers, production usage figures or pricing.
