Arcveil

Arcveil is developing privacy-focused controls that let AI agents spend funds under an encrypted mandate rather than giving them access to a user’s private keys. Built for Arc, Circle’s EVM-compatible Layer 1, the system is designed to let agents propose actions in relative terms, such as reducing an asset position by a percentage, without seeing balances or portfolio totals. Mandates can define permitted assets, spending limits, active hours, expiry dates, and conditions that stop activity.

Arcveil’s planned transaction pipeline combines a user-device signature with a policy co-signer’s approval, so actions are checked against the mandate before settlement. Each completed action generates a receipt intended to show that policy requirements were met without exposing sensitive details. The company also offers a browser-based receipt verifier, with a documented receipt format and checks that run locally; some verification reads use Arc mainnet. Arcveil distinguishes shipped features from those still in development: the receipt format and verifier are available, while key mandate and transaction components remain planned.
