Three chains. One inbox. Coverage begins after your watch is saved.

01 / THE SIGNAL

The chain never
looks away.

What SENTR saw in the last hour. Real public events, reduced to the event type and chain.

PUBLIC OBSERVATIONSCONNECTING

Checking the observation feed…

A sample of scanned blocks, not all chain activity. Events are not necessarily threats.

02 / THE WATCH

From chain activity
to a clear next step.

Quiet until there is something to review. Every alert carries the context you need.

Paste. Pick. Watch.

Add any public wallet address and choose your chains. Connecting a wallet is optional.

The chain moves.

SENTR reads new blocks for approvals, outgoing funds and lookalike dust transfers.

You get the context.

An alert explains the change, links the transaction and gives you a next step.

03 / WHY WATCH

The keys were safe.
The money moved.

On 24 September 2026, Bitget reported unauthorised transfers from hot and warm wallets. CoinDesk reported about $352 million; Halborn later estimated $387.5 million. The reported attack spoofed unsigned transaction data in backend infrastructure. Private keys were reportedly not stolen.

SENTR CAN SEE

Supported on-chain outflows and approvals, after inclusion.

SENTR CANNOT SEE

Unsigned backend instructions, intent or transactions on unsupported chains.

Awareness is a layer. It is not a lock.

04 / THE TOKEN

NO CONTRACT ADDRESS YET

$SENTR

The token has not launched. There is no published contract address, price or allocation. Watching a wallet does not require a token purchase.

Your wallet has a history.
Give it a lookout.

Start with an address. Stay in control.
