Perimeter Protection is a last-resort security system in the event of a physical attack on you or your loved ones. A silent guardian, always on, ready to discreetly mobilize specialized intervention forces in case of attack.
/ How it works
You prepare dedicated wallets
You tell us which addresses you'll only use in case of extreme emergency.
Continuous monitoring, 24/7
Always onYour wallets are watched continuously.
A transaction is detected on one of your wallets
The moment one of your wallets shows outgoing activity, the protocol is triggered.
We contact you to clear up doubt
We call you and run through a script to verify whether you are safe.
We connect you to the intervention unit
Your identity and your live GPS are forwarded to a specialized tactical unit.
Your keys are protected. You aren't.
- Detects outflows under duress
- Scripted call to verify the threat
- Pre-briefed specialized unit coordination
- Protects the whole household at once
- Protects your keys from remote theft
- Does nothing if you're forced to sign
- Doesn't protect your family
- Alerts a monitoring station
- Not designed for the crypto scenario
- No link to your wallets
- Compensates after a loss
- Doesn't prevent the attack
- Reactive, not operational
We don't know who you are.That's the point.
Your identity is encrypted; the key to decrypt it lives in a vault on a separate machine in a different country, and releases only on a real event from you.
Encrypted at rest.
Sealed before storage. Keys held in a separate vault.
We can't see you.
24/7 watch on opaque IDs. Identity untouched.
Customer-triggered.
Only your alert unlocks personal information.
If we're compromised — no exploitable data.
One plan. Multiple people.
- 24/7 monitoring of pre-declared wallets
- Discreet panic button on your phone
- Verification call following a protocol
- Household geolocation if the risk is confirmed
- Specialized intervention coordination in France

Yes. The enterprise plan extends Perimeter to your most exposed team members, with a single contract in the company's name, centralized billing and a dedicated point of contact. Each beneficiary is onboarded individually.
The company holds the contract; your employees and their loved ones are the beneficiaries, protected 24/7, at the office as at home. The monitored wallets are dedicated low-balance wallets, distinct from the employee's actual holdings: the company funds protection without accessing its team members' real assets.
The enterprise plan activates from 3 beneficiaries. Custom pricing based on the number of people and the needs. Contact us for a quote, an operator will reach out.
Our architecture separates blockchain addresses from personal identity across physically distinct systems. If one is compromised, no exploitable data is exposed.
