# Token Sewage Spill on Base

Today, we will look at another peculiar case on Base: a flood of scam tokens deployed by the same deployer, who spits a new one out every few minutes. One such example is the [KOBE Token](https://blokiments.com/detailedView/base?pairAddress=0x08ce86385ca47ccfbbef1bb9e3993016015e17ea).

To avoid falling for such traps, check the **Security tab** in our detailed token view.

## How the scam works

### Funding Round

First, all associated wallets are funded. They are funded by ([0x317ECA62872f16F2f8Cc05ba21107851A331042D](https://basescan.org/address/0x317eca62872f16f2f8cc05ba21107851a331042d)), who we will call SEWAGE\_PLANT.

The funding round consists of:

### Setup

With wallets funded, the token and pool creation is done. The main CEO here is GRIMDRAIN:

### Token’s Life

Now come the TRASHMEN. They make a trade or two to pump some life into this token, hoping to entice victims to buy in. [Transactions Link](https://basescan.org/address/0x08CE86385cA47ccFBbEF1BB9e3993016015E17ea#tokentxns)<br>

### Drainage

A simple rug-pull is executed after a victim buys in and money is taken out.

### Cleanup

After the rug-pull is done, the token is dead and abandoned.

After some days (in KOBE’s case it was around 20 days later) another smart contract ([0x932ef0cFF81cBe6A71FC0A93Dd04aDCA4f18a7fB](https://basescan.org/address/0x932ef0cff81cbe6a71fc0a93dd04adca4f18a7fb)) is called ([TxLink](https://basescan.org/tx/0xa8c50289a4d27fe578c942868765b4530c1d4b1b2f93afc33cb11f020546fad8)) that buys a very small amount of this token. Since there is almost no liquidity, the price is shot up.&#x20;

This contract buys many scam tokens in the same transactions, pumping their prices so they look better retrospectively.&#x20;

After the scam is finished, all the TRASHMEN and GRIMDRAIN send the remaining funds back to SEWAGE\_PLANT, and the scam is immediately repeated.

**Cleanup - Total: $0.007799 :**

* 11 transfers back to sewage plant, where 1 transfer costs:
  * 0.000000205861007807 ETH, or
  * $0.000709, estimated cost on the day of tx

<mark style="color:red;">**TOTAL COST: $0.17 (on Base)**</mark>

### Ethereum costs

<mark style="color:red;">**TOTAL COST: $181.9 (on Ethereum)**</mark>

### Sumup

With costs for running a scam being 1000x cheaper on Base than on Ethereum, it is no surprise that automated scammers have moved to L2s, flooding them with shitcoins.
