A 2023 meme ERC20 named after the Sminem image, generated from a token factory template with a 1 percent fee on buys and transfers and ownership since renounced.

Historical Significance
This is what a meme token looked like once the form had been fully industrialised. The 2021 vaults nearby each required a curator, an artwork, a platform and a decision about what ownership of an image means. Two years later the same cultural impulse produced a contract assembled from a web form in a few minutes, where the only bespoke choices are the name, the supply and the tax rate.
Renouncing ownership is the detail that cuts both ways. It removes the deployer's ability to raise the tax or blacklist a holder, which is the usual reason a buyer worries about a contract like this. It also freezes a 1 percent toll to one fixed address for as long as the token is traded, with nobody left who could ever turn it off.

Description
Unlike the fractional vaults it sits beside, this is a plain token with no artwork behind it. The source carries the banner of the factory that produced it, 20lab.app, and the contract is that factory's standard output: OpenZeppelin ERC20 plus ERC20Burnable, Ownable and a TokenRecover helper, compiled with solc 0.8.7 and the optimizer at 200 runs.
The interesting part is the fee machinery, because it is configured and then frozen. Fees are held per operation and read 1 percent on transfers, 1 percent on buys and nothing on sells, all of it routed to a single recipient the source names in the code rather than describing generically. Collected tokens accumulate until the balance passes a threshold of fifty billion, at which point the contract swaps them for ether through the Uniswap V2 router it was wired to at deployment. The maximum wallet limit is set equal to the total supply, which switches it off.
Ownership has been renounced: owner() returns the zero address. Every setter on the contract, the fee rates, the recipient, the blacklist, the exclusions, the swap threshold, is owner only, so the configuration above is now permanent. Total supply is one hundred trillion tokens.
