@aeredium is the privacy-preserving chain of record for institutional digital-asset settlement. EVM-compatible Layer 1 producing 22 blocks per second at 250,000 transactions per second end-to-end, signed entirely by hardware-attested enclaves. Zero human validators. @aeredium does not replace public chains. It sits between them. The user's USDC enters AEREDIUM from Ethereum through a custody pool, lives encrypted on AEREDIUM during the period of activity, and exits to whatever destination chain the user selects. From outside, what is visible is the boundary — deposit and withdrawal events at the custody pool address. Inside, what occurs is encrypted, executed in the approximately 250,000 transactions per second under ongoing optimisation, and finalised on-chain, with selective disclosure to authorised parties through the AERKey Policy Engine. Public chains are the inbound and outbound rails. AEREDIUM is the encrypted settlement layer between them. The institutional thesis does not require any public chain to fail or change.
