Lab · A real on-chain tool

Mobick GuardSee the flow. Judge no one.

Honest P2P sellers have had their bank accounts frozen because a voice-phishing victim’s money was paid into them. As the ecosystem widens into WBMB and Uniswap, we need tools to protect each other — without becoming a regulator’s eyes or harming the privacy of people who mine their coins.

Show, don’t judgeNo risk scores, no “criminal address” labels. Only where coins came from, where they went, and the shape of it.
Every shape comes with normal reasonsFan-outs, fan-ins and peel chains happen every day at pools and exchanges, so the common normal reasons always sit beside them.
Privacy is not a red flagGood habits like fresh addresses or tidying change are not counted as patterns. Neither are coins mined without KYC.

Flow tracer

Enter a Mobick txid or address, or a WBMB 0x address or tx hash. The past grows to the left, what happened next to the right. Tap a node for its details, a shape for a red-pen mark on the drawing. Zoom with the buttons or Ctrl+wheel; drag to pan.

Where a coin came from, and where it went

Left: the transactions this coin came through. Right: where it moved afterwards. This browser asks blockchain.mobick.info directly.

For WBMB (0x addresses), only transfers since 9 October 2026 are shown. Earlier history is not indexed yet.

Where it came from

Once drawn, this splits the coin’s value by where it came from.

Shapes in the flow

A shape is not a verdict — the same shapes are common in normal activity. Tap one to mark it on the drawing.

One address or transaction ID per line — for example the counterparty of a trade that got your account frozen. Add a note after a comma. Flows that touch the list are marked red. It is your private note, not shared, and a connection alone does not mean it is the same person.

P2P seller protection

Scam money enters through the bank, not the chain. The surest protection is thirty seconds before accepting a payment, and the evidence you keep yourself for every trade.

First: do you need P2P at all?

The coins may move safely on-chain, but when money arrives from a stranger’s account, nobody checks where it came from. Laundered money has reached P2P venues before, and many sellers had their accounts frozen at once. Buying with your own money on an exchange and swapping via Uniswap and MobickOne, or trading on LBank, is safer.

Name tag. A name tag travels with your coins. The sender and the recipient. In Korea today, for one million won or more.
19 Feb 2027. Every amount, from February nineteenth, twenty twenty-seven. Personal wallets and overseas exchanges go by risk, usually only when you send to yourself.
Predict. Your turn to predict. Is it fine to receive in a family member's name? Answer: no. The recipient is always you. No. The recipient is always you. Using someone else's name can count as moving other people's money, and accounts can be frozen.
Splitting. Don't split transfers either. Splitting under the threshold is a classic red flag.

If you still sell P2P, run this check before you accept a payment.

30-second check before you accept a payment

If any applies, stop before sending coins. Nothing here is saved anywhere.

The depositor’s name differs from the person you are talking to
The most common scam shape: the fraudster tells a victim to pay into your account. The fraudster gets the coins; your account gets frozen.
They want to pay in several parts or from several names
This can be several victims’ money pooled into one trade.
After paying they say “wrong amount, refund to another account”
The refund itself can feed the scam. Do not send to the account they name; ask your bank first.
They rush to buy a large amount, even above the price, without haggling
Flagged in the FSS consumer alert 2026-5. It is someone else’s money to them.
A brand-new account, or they want to move the chat off the platform
Moving off-platform also removes the records you would need to prove a fair trade.
They give several receiving addresses, or one that forwards immediately
This can be an attempt to scatter the coins fast. Check the address in the flow tracer first.
They ask you to delete or hide your listing
Flagged in the FSS consumer alert.

If none applies: confirm the depositor name and amount in your bank app, keep the evidence listed in ③ on your own device, then send.

If your account is frozen: there is a set path

Under Korea’s Telecom Financial Fraud Act (renamed from 1 Oct 2026; crypto exchanges are now covered too). This is not legal advice — for large sums, talk to a lawyer.

FreezeArt. 4
On a victim’s or investigator’s request the bank freezes the account at once and notifies you. At first the whole account is frozen.
Public noticeArt. 5 · 2 months
The FSS posts a notice and tells you. The clock starts on this date.
ObjectionArt. 7 · within 2 months of notice
File the objection form, ID copy, and objective evidence that the money was fair payment (Art. 7(1)2) with the account’s bank. You can also ask to release everything except the victim’s amount (7(1)3, since Aug 2024). It fails if you knew, or should obviously have known.
ReleaseArt. 8
If accepted, the freeze ends — though it may stay for up to 2 months after the victim is notified unless your evidence is strong. Since May 2026 the FSS reportedly aims to review objections within 5 business days.
If you missed itArt. 9 · 13
Two months after the notice the claim lapses and goes to the victim. If you had a valid reason for missing the deadline, you can claim from the FSS.

When the freeze ends, the linked non-face-to-face banking restriction (Art. 13-2) is lifted too. False claimants owe the account holder damages (Art. 11-2). Source: Korea Law Information Center, current text checked 2026-10-09. law.go.kr ↗

What to keep yourself, every trade

In an objection, nothing helps more than proof that you sent these coins, at that price, to that person. This site takes and stores nothing; keep the items below on your own phone or computer.

You can check where a txid went with the flow tracer above; it only looks things up and stores nothing.

FAQ

Can this tell me who the scammer is?: No. An address does not reveal its owner, and the same shapes appear in normal activity. The tool helps you look at a counterparty’s address before trading, and keep evidence that your trade was fair if trouble comes. The real harm happens on the bank side, so the strongest protection is the pre-payment check.
What is the mined-origin badge?: It appears when, walking back, at least half the value came from new-chain mining rewards (a coinbase, or a pool address that receives coinbases). Mined coins have the clearest origin there is. The printed record can be recomputed by anyone; it is not a tax judgement or advice.
How are the source shares computed?: It walks back through inputs, splitting each transaction’s share by input value. Coinbases from block #2 and mining-pool addresses count as mining rewards; the block #1 coinbase and the migration payout address (1GtiJ…) as the New Bedford migration; the 16 published wallets as public goods. It stops at very busy addresses or after about 120 lookups and says so.
Since when is WBMB (BSC) history available?: Public BSC nodes only serve about the last hour of logs, so this site collects WBMB transfers every minute and can draw flows only from when collection began (October 2026). Older transfers can be viewed one by one by entering a tx hash. The current range shows in the tracer’s “Where it came from” panel.
Can I share my watchlist?: For now it lives only in your browser. A public list can do irreversible harm to anyone wrongly on it, so there isn’t one. You can copy the text and hand it to someone you trust.
