Whitepaper
How SenseiFi keeps wallets safer before you sign
This paper explains the problem we solve, how SenseiGuard and the Guard dashboard work together, and where the product goes next.
Abstract
SenseiFi is a Web3 security platform that helps users protect wallets before value is lost. It combines a dashboard with a browser extension that reviews wallet connections and transactions in real time, scores risk, and records activity so users can act with clearer information.
The problem
Crypto users lose funds through phishing sites, malicious contracts, unlimited approvals, and signing requests they cannot interpret. Most wallets ask users to approve first and understand later. By then, the damage is often done.
Existing tools are fragmented: scanners without continuous protection, dashboards without interception before you sign, and alerts without a clear path from warning to action.
The SenseiFi approach
SenseiFi’s thesis: the differentiator is how accurately you decode and interpret transactions before signing, not the presentation layer alone.
SenseiGuard
Browser extension
- Intercepts connect and sign requests on dApps
- Scores risk before the wallet prompt finishes
- Warns or blocks high risk actions
- Saves approved sites as connected dApps
SenseiFi Guard
Security dashboard
- Wallet health, live activity, and timeline
- Connected wallets and connected dApps
- Threat intelligence and contract scanning
- Protection settings and emergency controls
How protection works
From linking a wallet to recording a connected dApp, SenseiFi keeps the human decision in the loop while removing blind spots around what a request can do.

Record
Activity & connected dApps
- User links a wallet on SenseiFi with a one time sign in message. No transfer.
- The SenseiGuard extension adopts that session.
- On a dApp, connect or sign requests are intercepted.
- SenseiFi’s backend evaluates site and transaction risk.
- The user sees allow, warn, or block before irreversible action.
- Approved connections can appear as connected dApps for later review.
Architecture
Analysis runs on the SenseiFi backend so risk logic stays consistent and updatable without shipping a new extension for every detector change.

Who it is for, and which chains
- Wallet holders get a risk result before the wallet prompt on connect and sign.
- On-chain users get selector checks for unlimited approvals and similar patterns, plus an API score on EVM transactions.
- DeFi users get domain checks, a cached threat feed, and a connection check before a site is saved.
- Spenders are named because the privacy policy describes SenseiCard. Card issuing is not specified in this system, and pre-sign protection is not claimed for card spend.
- Web3 teams get a dashboard of connected wallets, dApps, alerts, and scans. SenseiFi does not custody a treasury.
Wallet linking today registers Ethereum, BNB Smart Chain, Polygon, Base, and Base Sepolia. The extension also hooks Solana, Cosmos, and Bitcoin providers, with local heuristics only. Any other chain is a plan, not current support. Mobile apps are covered by the privacy policy and are outside this architecture.
Attacks covered, and attacks that are not
In scope: phishing and lookalike domains, contracts and domains on the threat feed, unlimited approvals, setApprovalForAll, transferFrom, eth_sign and typed-data signatures including permit-style v4 payloads, and wallet connections on the hooked providers.
Out of scope in this build: front-running and sandwich attacks, a leaked seed or a compromised wallet, address poisoning of past recipients, bridge and governance attacks that look like ordinary calls, and simulation of Solana, Cosmos, or Bitcoin transactions.
Governance and legal
Founders, a leadership roster, a legal entity, and a jurisdiction are not published. Advisors are not published, so none are described as having control. The site is senseifi.io. Support is support@senseifi.io. The privacy policy lists privacy@senseifi.com for data requests. Both addresses are in print today.
Risk policy lives in extension settings and in the API score. Users can turn protection off, proceed past a warning, disconnect, or request deletion of personal data. There is no published external board. SenseiCard’s issuer, processor, and license are unpublished.
SenseiFi is not financial, legal, or investment advice. Roadmap dates are current plans, subject to change. The in-product terms limit liability for indirect and consequential loss, which includes a missed drain and a blocked legitimate transaction. SenseiFi never holds keys and never moves funds.
Business model
Default prices in the client are Basic $15 per month, Pro $30, Pro+ $60, and Premium $200, with annual totals of $150, $300, $600, and $2,000. A free tier is listed with one wallet and lower quotas. The API can replace the displayed prices. Subscriptions are the funding model. A split between engineering cost and detection-data cost is not published.
No SenseiFi token exists in this product, and this version does not plan one. No supply or utility is specified.
Roadmap
Quarters below are intentions as of 11 October 2026. They can change.
- Q4 2026: keep this paper aligned with the extension and the privacy policy, including model training and encryption scope.
- Q1 2027: API scores for non-EVM signing, and published p50/p95 latency for the analyze call.
- Q2 2027: name the SenseiCard issuer and license, or mark the card unreleased and narrow the privacy policy.
- Q3 2027: an independent review with firm, date, and scope, plus a disclosure address.
- Q4 2027: a labeled test set and published false-positive and false-negative rates.
Public figures
The homepage currently shows $278B, <1s, and 300+ signals. None of those strings has a methodology or an as-of date, so this paper does not treat them as measured results. The current source does not contain $409B, 442+, $-409B, or <-1s. The counter animates upward from zero and does not introduce a minus sign.
Trust and privacy
Users sign a message to authenticate. SenseiFi does not hold keys or move funds. SenseiGuard sits in front of the wallet prompt. It does not replace the wallet.
Transaction context and telemetry can be used to train detection models, as the privacy policy states. That processing is separate from key handling. Dashboard data is scoped to the signed-in user. Insights stay advisory.
What success looks like
Fewer signatures the user did not understand. A visible list of connected dApps. A documented result when the API is down or wrong. Published accuracy, once it is measured.
Conclusion
SenseiFi exists to put security intelligence in front of the signature, and a durable record behind it. Review before you sign through SenseiGuard, and visibility after you connect through the Guard dashboard, form the product’s core loop.

Effective Date: April 18, 2026
Last Updated: April 18, 2026
1. Introduction
SenseiFi ("SenseiFi," "we," "our," or "us") is committed to safeguarding the privacy, confidentiality, and integrity of user data. This Privacy Policy explains how we collect, use, disclose, and protect information in connection with our decentralized finance security platform, including our mobile applications, browser extensions, web dashboard, and related services (collectively, the "Services").
SenseiFi operates at the intersection of blockchain technology, artificial intelligence, and digital payments, offering tools such as wallet security monitoring, transaction analysis, threat detection, and crypto-based payment solutions. Given the nature of decentralized systems, we are deliberate in minimizing data collection while maintaining high standards of security and usability.
By accessing or using SenseiFi, you acknowledge that you have read and understood this Privacy Policy.
2. Information We Collect
We adopt a data-minimization approach. The categories of information we may collect include:
2.1 Information You Provide
- Account details (e.g., email address, username)
- Subscription and billing information
- Customer support communications
2.2 Wallet and Blockchain Data
- Public wallet addresses
- Transaction metadata (e.g., contract interactions, token approvals)
- On-chain activity necessary for risk analysis and security alerts
Important: SenseiFi does not collect or store private keys, seed phrases, or wallet credentials.
2.3 Automatically Collected Information
- Device and browser information
- IP address and approximate geolocation
- Usage analytics (features accessed, session duration)
- Log data (errors, system diagnostics)
2.4 AI and Security Analysis Data
To provide intelligent insights and protection:
- Smart contract interaction patterns
- Token behavior and risk signals
- Phishing URLs and suspicious domain interactions
- Transaction simulation inputs and outputs
2.5 Payment and Card Data (SenseiCard™)
Where applicable:
- Card issuance data (processed via third-party providers)
- Transaction records and spending analytics
- Fiat conversion metadata
Note: Sensitive payment data is handled by regulated third-party payment processors and is not stored directly by SenseiFi.
2.6 SenseiFi - Web3 Wallet Security & Airdrop Intelligence (SenseiGuard) browser extension
If you install our Chrome extension ("SenseiFi - Web3 Wallet Security & Airdrop Intelligence" / SenseiGuard), the following applies in addition to the categories above. We keep this list aligned with what the extension actually stores and sends.
Local storage on your device (via Chrome storage.local): user protection settings (thresholds, toggles), a list of recent security alerts, a cache of threat-intelligence data fetched from our servers, your wallet session / connected public address after you connect, a short queue of security-relevant events pending upload, and per-tab domain risk snapshots used to show warnings. We do not store private keys, seed phrases, or wallet secrets in the extension.
Network requests to our API (HTTPS): the extension may call our backend to (a) analyze a pending transaction or signing request, (b) check dApp/site context when connecting, (c) register your connected wallet address and chain when you choose to connect, (d) download a periodic threat feed (e.g. malicious contract/domain lists), and (e) send queued telemetry events (for example transaction evaluation outcomes, domain-risk detections, and sync heartbeats). Payloads are limited to what is needed for security analysis and service operation.
Site access: broad access to websites you visit (http(s)://*/*) is optional and requested when you enable site protection or connect a wallet from the extension, so we can inject our protection script and interact with the page's wallet provider on dApps. If you do not grant this access, in-page protection and wallet connect on normal tabs will not work until you allow it. Access to our API host is separate and used for the requests described above.
Notifications: the extension may show system notifications when we block or warn on a high-risk transaction or flag a suspicious domain, so you notice even if the tab is in the background.
