How can scammers benefit from cheap fees on L2 networks?

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.
To avoid falling for such traps, check the Security tab in our detailed token view.
First, all associated wallets are funded. They are funded by (0x317ECA62872f16F2f8Cc05ba21107851A331042D), who we will call SEWAGE_PLANT.
The funding round consists of:
TxLink; Jul-16-2024 08:50:35 PM +UTC: Funding (0xD667F8e87311D9faC7911DEa36f628B3ac7d3FAA) - GRIMDRAIN, amount 5 ETH
TxLink; Jul-16-2024 08:50:43 PM +UTC: Funding (0xf56a2fEB6AE061C02388A0Ad0c71ce1a3d42f41e) - TRASHMAN_01, amount 0.49 ETH
TxLink; Jul-16-2024 08:50:51 PM +UTC: Funding (0x980fA57ec336BE9CEE896B318Be4F3f023304817) - TRASHMAN_02, amount 0.49 ETH
TxLink; Jul-16-2024 08:50:59 PM +UTC: Funding (0xA546116Af1d960BB75A38AE74c3FC5adB3d49b9b) - TRASHMAN_03, amount 0.49 ETH
TxLink; Jul-16-2024 08:51:05 PM +UTC: Funding (0x29ACE42B7F37dc7Eb5e7Fb2cCc386046B2B91e95) - TRASHMAN_04, amount 0.49 ETH
TxLink; Jul-16-2024 08:51:09 PM +UTC: Funding (0xaD45A78D95e2eD7a1f93471FE77e23383614bC4F) - TRASHMAN_05, amount 0.49 ETH
TxLink; Jul-16-2024 08:51:13 PM +UTC: Funding (0x637069845c3D4Bf84f8d6BBa772FE41A37931880) - TRASHMAN_06, amount 0.49 ETH
TxLink; Jul-16-2024 08:51:21 PM +UTC: Funding (0x348c559fd0712DC7EAB72C9793E61FEDc86150A5) - TRASHMAN_07, amount 0.49 ETH
TxLink; Jul-16-2024 08:51:29 PM +UTC: Funding (0x558d012b327f649C6Dffec2cd663e255A009888e) - TRASHMAN_08, amount 0.49 ETH
TxLink; Jul-16-2024 08:51:41 PM +UTC: Funding (0xA4c87e94780cF7b2B84d8823F0d20582c9aA564d) - TRASHMAN_09, amount 0.49 ETH
TxLink; Jul-16-2024 08:51:49 PM +UTC: Funding (0x4307EFD40FD32819966C18d2c4b39d288de4e579) - TRASHMAN_10, amount 0.49 ETH
With wallets funded, the token and pool creation is done. The main CEO here is GRIMDRAIN:
TxLink; Jul-16-2024 08:51:59 PM +UTC: Plops down another token, in this case KOBE (0xB26c57c1875522360734A618A858F7AB59BE228f)
TxLink; Jul-16-2024 08:52:33 PM +UTC: Creates the sewage pool (0x08CE86385cA47ccFBbEF1BB9e3993016015E17ea) with this token and adds liquidity to it.
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
A simple rug-pull is executed after a victim buys in and money is taken out.
TxLink; Jul-16-2024 08:56:47 PM +UTC: Victim buys the token
TxLink; Jul-16-2024 08:57:17 PM +UTC: GRIMDRAIN executes a rug-pull
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) is called (TxLink) that buys a very small amount of this token. Since there is almost no liquidity, the price is shot up.
This contract buys many scam tokens in the same transactions, pumping their prices so they look better retrospectively.
After the scam is finished, all the TRASHMEN and GRIMDRAIN send the remaining funds back to SEWAGE_PLANT, and the scam is immediately repeated.
Let's finish things up by comparing the transaction fees a single scam costs him and the fees such a scam would cost on Ethereum.

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.
