Using the CGGMP24 protocol, control is split across multiple hardware-attested enclaves, and organisations set an M-of-N approval policy (e.g., 3-of-5 signatories using passkeys) before any privileged action like minting or upgrading a contract can proceed. The product supports EVM-compatible chains, lets customers independently verify the assigned threshold key, and does not fix vulnerabilities in the underlying contract code itself. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is AERSeal and how does it prevent a single stolen private key from controlling a smart contract? AERSeal is a security product from AEREDIUM that replaces single-key control of smart contract admin functions with a threshold signing system. It splits key control across multiple hardware-attested enclaves using the CGGMP24 protocol, never reconstructing the full key, and requires an M-of-N approval policy (such as 3-of-5 signatories using passkeys) before privileged actions like minting or upgrading are authorized. _Teams hardening smart contract admin access can track threshold-signing approaches like this via daily.dev._ ### Does AERSeal require redeploying an existing smart contract to add threshold-based admin control? No, the existing smart contract does not need to move or redeploy. AERSeal identifies the contract's privileged functions, transfers control over them to a threshold key, and verifies onchain that the transfer is complete, supporting Ethereum Virtual Machine and other EVM-compatible networks. _Developers evaluating no-redeploy security upgrades for EVM contracts can follow updates like this on daily.dev._ ### Can AERSeal fix vulnerabilities in a smart contract's own code? No, AERSeal does not remove vulnerabilities from a smart contract's underlying code. Its scope is narrower: it reduces the security and operational risks that arise when privileged contract functions depend on a single private key, rather than auditing or patching the contract logic itself. _Anyone weighing key-management tools against code audits for contract security can follow the space on daily.dev._ ## Similar posts on daily.dev -
