See the transaction before it drains you.
Shingan watches your EVM wallets — approvals, allowances and outflows — across six chains and warns you on Telegram before funds are lost. It never holds your keys and can never move your money.
No keys, no custody
Shingan only ever reads public chain data. It never asks for a seed phrase or private key and cannot sign a transaction.
Warnings where you are
Alerts arrive in Telegram the moment a risky approval or a large outflow is detected — not on a dashboard you forget to open.
Revoke in one tap
When an allowance is dangerous, Shingan gives you a link to sign approve(spender, 0) from your own wallet.
How it works
Four steps, one of them yours.
Connect a wallet
Send /connect 0x… to the bot. Address only — read-only. Add one wallet on the free plan, up to 999 on self-host.
Shingan watches
It ingests approvals and transfers across all six chains and scores risky spenders against threat intelligence.
You get warned
Unlimited approvals to unknown contracts, dangerous allowances and large outflows trigger an immediate alert.
You revoke
Open the deep link, sign the revoke yourself. Shingan never touches your keys at any point.
Six chains, one guard
Ethereum, Base, Polygon, Arbitrum, Optimism and BNB Chain.
Approval & allowance scan
ERC-20 approve and NFT ApprovalForAll events, with unlimited-allowance detection.
Outflow alerts
Native and token transfers out of your watched wallets, delivered as they happen.
Risk scoring
Spender and token reputation via threat intelligence, cached and applied to severity.
Natural-language assistant
Ask /ask about your approvals and alerts in plain English.
FAQ
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 yourself.
Is it free?
Yes — the free plan covers one wallet with full six-chain monitoring. Paid plans add more wallets and higher assistant limits.
How do I pay?
In crypto, directly to a Shingan address. The bot issues an invoice with the exact amount; payment is detected on-chain and your plan activates automatically.
Which chains are supported?
Ethereum, Base, Polygon, Arbitrum, Optimism and BNB Chain.
How does revocation work?
Shingan builds the approve(spender, 0) call and gives you a link. Your wallet signs it; Shingan never sees your keys.
Do you give financial advice?
No. Shingan is a security tool, not an adviser. It never recommends trades or investments.
What data do you store?
Your Telegram ID and the public wallet addresses you connect. No KYC, no email required, no tracking cookies. See the Privacy Policy.
