INDEPENDENT BITCOIN SECURITY

KNOW WHEN YOUR BITCOIN MOVES.

Your keys stay yours. Your Bitcoin shouldn't move without you knowing. UTXO.red is building watch-only UTXO monitoring, spend alerts, and a clear record of what happened.

BITCOIN-NATIVE OBSERVABILITY

MULTI-NODE DESIGN

KEYLESS MONITORING

OPEN EVIDENCE STANDARD

01 / UTXO WATCH

Eyes on the mempool.
Hands off your keys.

A security layer for your Bitcoin holdings—not another wallet. Watch specific outputs, observe spend attempts, and build a reliable history of activity.

01 — PRECISE MONITORING

Watch exact UTXOs.

Track individual Bitcoin transaction outputs by txid and output index. No wallet seed, xpub, or signing access needed.

02 — BROADER VISIBILITY

Independent node views.

Designed to compare observations from Bitcoin Core and alternative relay policies, including Libre Relay.

03 — ACTIONABLE SIGNALS

Know what happened.

Planned email alerts, confirmation tracking, conflicting spend observations, and an event timeline you can audit.

02 / HOW IT WORKS

Three steps. Zero keys.

Bitcoin is public. Monitoring it doesn't require control of the coins—and it shouldn't.

STEP 01 / REGISTER

Add your outpoints.

Enter a transaction ID and output index. You can watch a UTXO whether or not you own it; watching is not proof of ownership.

STEP 02 / OBSERVE

We watch for spends.

Our planned node network inspects mempool transactions and blocks for inputs that spend your watched outputs.

STEP 03 / RESPOND

You get the signal.

Review the transaction and its confirmation status. Alerts report observations, never assume a spend is theft.

Your keys.
Your control.

UTXO Watch is designed to observe—not spend. No custody, no seed phrases, and no private-key access. Your watchlist is private account data, not a public directory of your holdings.

No signing authorityMonitoring never needs your Bitcoin spending keys.
Watchlists are not publicMonitored outpoints are kept separate from public evidence commitments.
Designed for portabilityEvidence exports and future integrations shouldn't depend on a single provider.
03 / THE ROADMAP

Protect now.
Prepare for later.

One practical security service, one open public-good protocol, and one carefully gated research track.

THE UTXO EVIDENCE PROTOCOL

Open evidence. Private infrastructure.

Anyone should be able to create and verify historical control evidence without relying on UTXO.red. The UEP protocol and verifier are intended to be open; the UTXO.red monitoring service is independent and commercially operated.

04 / QUESTIONS

Straight
answers.

Bitcoin security is too important for vague promises. Here's what the service can—and cannot—do.

Do you need my private keys or seed phrase?

No. Watch-only monitoring needs only the UTXO outpoint: the transaction ID and output index. Never submit a seed phrase or private key to a monitoring service.

Can I monitor UTXOs I don't own?

Yes. Bitcoin transactions are public. Watching an outpoint does not require ownership and is not evidence that you control the Bitcoin.

Can UTXO.red prevent my Bitcoin from being stolen?

UTXO Watch is an observation and alerting product, not a theft-prevention guarantee. Spending may be seen only when a block confirms, including when transactions are sent privately to miners. Emergency transaction response is a separate research track.

Will my watchlist follow new wallet outputs automatically?

Not with a static list of UTXOs. As outputs are spent or new ones are received, the watchlist must be updated. Privacy-preserving wallet integrations are a potential future feature.

Does UEP establish legal ownership or make Bitcoin quantum-safe?

No. It aims to preserve independently verifiable historical evidence of key control. It cannot establish legal title, prevent quantum attacks, or compel the Bitcoin network to restore coins.

A NEW SECURITY LAYER FOR BITCOIN

Security starts with visibility.

We're building the watch-only infrastructure Bitcoin holders should be able to rely on—without surrendering custody or compromising their keys.
