The guard · read-only · twelve chains
See the transaction
before it drains you.
Shingan watches approvals, allowances and outflows and shows you the risk in your dashboard before funds are lost. It never holds a key and can never move your money.
No signup. No keys. A public address, read-only. See a live example.
Free for one wallet. Pro adds more wallets and history. Paid in crypto, no auto-renewal.
Why is this one risky?
Tap Revoke. Your wallet signs approve(spender, 0); the allowance goes to zero.
Demo alert. In the dashboard, every alert carries the reason and the revoke link.
What the guard catches.
The ways self-custody wallets get drained, watched continuously. Not when you remember to check.
Unlimited approvals
A dapp asks for an infinite allowance to an unknown contract. Shingan flags it the moment it lands.
Drainer contracts
Known-bad spenders and phishing contracts, scored against threat intelligence before you sign again.
Large outflows
Native and token transfers leaving the wallet, sized against the balance, delivered as they happen.
Honeypot tokens
Tokens you can buy but not sell, or with hidden mint and ownership traps.
Brand-new spenders
Contracts deployed days ago, before they have any reputation at all.
Dormant allowances
Old approvals you forgot about, still able to move your tokens.
Four steps. One of them is yours.
The guard is deliberately boring: read the chain, score the risk, alert you, hand you the revoke. You sign.
Connect a wallet
Add the wallet in your dashboard. Address only. One wallet free.
Shingan watches
Approvals and transfers are ingested across twelve chains and scored.
You get warned
A dangerous approval or a large outflow appears in your guard and, if you turn it on, arrives by email.
You revoke
Open the link and sign it yourself. Shingan never touches your keys.
When it goes wrong, you get a plan.
No product can undo a transaction. The difference is knowing in the first minute, and knowing what to do next.
Clear it before it is used.
Open the alert, read the spender and the flags, tap Revoke, sign in your wallet. Confirm the allowance is zero. The Why button shows the exact flags.
Stop signing. Move what is left.
Revoke every high-risk approval, move remaining funds to a wallet you control, and do not sign another transaction from the exposed wallet. Shingan cannot reverse the transfer.
Read before you sign.
If a signature asks for an approval, not a login, stop. Check the spender and the token. Use the free transaction tool to see what it actually does.
The score is not a black box.
The wallet health score is a heuristic from the approvals Shingan tracks. The formula is public, and the scan shows the deductions.
Start at 100. Each active approval −2. Unlimited −4 more. Spender risk 80+ −13. Risk 50–79 −6. Risk 20–49 −2. Dormant over 180 days −1. Floor at 0.
A ≥ 90B ≥ 75C ≥ 55D ≥ 35F below
It does not measure off-chain risk, a brand-new approval that has not been ingested, or a chain outside the twelve. It is guidance, not a guarantee.
What moves a spender score
- Honeypot or cannot-sell token: the largest weights.
- Malicious or phishing address, blacklist doubt, stealing attack.
- Hidden owner, mintable, pausable, take-back ownership.
- Closed source or proxy contracts.
The score combines token security and address security, cached and refreshed. The Why button on every alert shows the flags behind it.
Twelve chains, one guard.
Ethereum, Base, Polygon, Arbitrum, Optimism, BNB Chain, Linea, Scroll, zkSync Era, Avalanche, Gnosis and Celo.
Pricing, without a card.
Paid in crypto. No auto-renewal: cancel by not renewing. One wallet is free, forever.
Free while the web guard is in beta. One wallet, in-app alerts and email. More wallets and priority alerts will be a paid add-on inside the dashboard. No bot, no auto-renewal.
The guard lives in the same email account as the path. Add the wallet you get paid into; alerts appear in the dashboard and by email. No keys, no custody, no Telegram.
The honest answers.
Do you hold my keys or funds?
No. Shingan is non-custodial and read-only. It never asks for a seed phrase or private key, and it cannot sign or move anything. You sign every revoke.
Is it free?
Yes. One wallet with full twelve-chain monitoring. Paid plans add more wallets and higher assistant limits.
How much does it cost?
The guard is free while the web version is in beta: one wallet, in-app and email alerts. The path is free to see; projects use credits, topped up in the dashboard.
What happens if a drain happens?
You get the alert, the flags and the revoke link. Shingan cannot reverse a transfer. It helps you stop the next one and move what is left.
What data do you store?
Your email and the public wallet addresses you add. No KYC, no tracking cookies. See the Privacy Policy.
Do I need a crypto wallet?
Only for the guard. The path works with a bank, PayPal, Wise or crypto; the guard watches EVM wallets when you use one.
