THE TOOLS BEHIND YOUR NEXT MOVE
What powers SENTR
Built with Pimlico
Pimlico bundles and sponsors one EIP-7702 user operation for panic, fix-from-alert and Safe send. Your wallet keeps the same address. A compatible wallet must support atomic calls and a paymaster service on Robinhood Chain 4663. SENTR verifies EntryPoint v0.8 and the sponsored receipt. You review delegation in your wallet; that delegation remains until you change it.
Pimlico does not detect threats, clear warnings or recover lost funds. Sponsorship needs a configured key, credit, an operator-approved wallet and policy approval. A public gas quote does not confirm sponsorship. Review keeps a gas reserve; the wallet must sign temporary access for an active watch before requesting sponsorship. With no key configured, the review says “Pimlico offline, key pending” and clearly labels the existing self-paid path. SENTR sponsorship is enabled only for 4663; Ethereum and Base keep their self-paid tools.

Built with XMTP
A persistent SENTR sender delivers newly scanned alerts to the XMTP inbox you select. Enter or connect your inbox address on Watch, then sign a consent message. An existing inbox on the sender's XMTP network is required. The watch itself needs no signature. Disable delivery or delete the watch to cancel queued alerts.
XMTP is independent of the watched chain. SENTR alerts can describe Robinhood Chain, Ethereum or Base. XMTP does not watch those chains, decide risk or execute a fix. Delivery can be delayed or retried; an alert ID lets you recognize a repeated delivery. An inbox receipt does not prove a phone notification appeared. Deleting a watch does not recall a message already sent.
The sender preserves its encrypted database on private disk outside the website. If it is unreachable, Watch says “XMTP offline, sender not configured”. Development-network delivery is tested separately from a production sender. The public watch service still needs a public host; the API is VM-only today.
Start in three steps.
Paste a complete 0x wallet address on Home or Watch. Select Robinhood Chain, Ethereum, Base, or any combination. Press Start watching. No wallet signature is requested.
Saving a watch reads the current chain head and records a starting block. Later activity enters your inbox after confirmation. Watch saved means registration succeeded; Current means the scanner has reached its confirmed target. A delayed status means there is a gap.
Read an alert, not a verdict.
Open the transaction link and compare it with what you expected. Transfers you made intentionally also appear. An unknown spender is simply one this watch has not seen before. Do not infer safety from an empty inbox.
If an approval is unexpected, choose Review / revoke. SENTR shows the contract, spender and chain before asking your connected wallet to send a revoke transaction. You pay network gas. Revoking cannot bring back funds that already left.
Keep the tab closed. Stay informed.
Choose Enable notifications in your watch. Your browser asks permission and creates a Web Push subscription. This needs HTTPS in production and a supported browser. On iOS, add the site to your Home Screen first. If permission is denied, the inbox still works. Push-service acceptance is not proof that a notification appeared on your screen.
One click to leave.
Press Unwatch + delete in the dashboard. The watch, saved push subscription, derived history and alerts are deleted from the active store. The local access token is removed too. If you clear browser storage first, you lose access to that watch, so unwatch before clearing it. Browser notifications already delivered stay under your browser’s control.
About $SENTR.
$SENTR has no contract address yet on the Pons / Robinhood Chain path. No contract address, supply, price, allocation or economic rights are published. Monitoring is independent of holding a token. The site only shows a live contract after its address and SENTR symbol have been checked on chain. Do not treat a token as insurance.
From an alert to a decision.
Open Protect to revoke found approvals, move selected ERC-20 tokens and native coin, create a fresh stealth destination, or use a small burner. Safe send checks outgoing history and your address book. Each plan shows full addresses, amounts, calldata and fees before your wallet signs.
Keep the latest encrypted vault backup and its passphrase. Private escape has no public recovery announcement. Import the backup and scan saved destinations to recover. Burning removes the local burner key, not downloaded backups or the remaining gas reserve.
