Introducing
@0xMiden Guardian:
A Non-Custodial Compliance Layer for Private Accounts on
@0xMiden — built for institutions that need privacy AND policy enforcement.
Today, blockchains force a tradeoff. Public chains like
@ethereum expose everything — balances, counterparties, transaction history. That's a liability for any institution trying to operate onchain.
But fully private chains aren't the answer either — once money goes in, there's no way to validate compliance. No AML, no policy, no audit trail.
Miden is different. Private accounts on Miden store state entirely offchain — not encrypted onchain, literally offchain. Only a cryptographic commitment lives on the chain. This is what makes Miden parallelizable and performant, but it also means private state management feature is a must.
That's where Guardian comes in.
TLDR:
- Guardian is a non-custodial off-chain coordination layer for private accounts
- It backs up, syncs, and co-signs transactions — without ever taking custody
- Multi-key threshold design — guardian holds one key, can never move your funds alone
- Operators configure their own compliance module — AML screening, spending limits, geo-based policy controls
- Users can rotate guardians anytime using their own keys
- Built with
@OpenZeppelin, fully open source and ready for you to backup your private state on Miden!
