dat hele **** crypto kan me gestolen worden, maak altijd verkeerde keuzes, maar NFT's daarentegen, vandaag weer een NFTje tegen 2000% winst verkocht, en dan staan er nog wat NFT packs op 700% die ik afgelopen donderdag heb gekocht, en nog 100+ andere op minstens 300%.

wat een heerlijke hype, de NFT's gingen omhoog trouwens tijdens de btc drop

( is eigenlijk ook gewoon crypto maar op een andere manier )

Ja, of Eiffel. Maar precies: het is een hobbyprojectje en geen levenswerk, dus het moet wel een beetje leuk blijven.

De punks zijn leuk maar daar is het te laat voor.
sws die ETH fees

In a simplified picture, generalized frontrunners scan the mempool and try replacing addresses in pending transactions with their own address (or just sending the same calldata from their address). They check if these modified transactions will make them money, and broadcast them only if they will.

For your use case, you should be able to avoid these attacks by, e.g. making whatever function you are calling on your custom contract only callable from your address. For public-facing applications it's much more complicated.

If you are interacting with public DEXs (as you mention you are) you may still suffer from attacks however. There are definitely more targetted frontrunners for Uniswap, but I don't know if they're sophisticated enough to decode internal calls or if they just look for simple transactions to the Uniswap router.

If you're looking for the overall most sophisticated group of developers on Ethereum, it's people running generalized frontrunners.

I've played around near them for years (since CryptoKitties first came out) and they're always ahead of the game compared to everyone around them. You need to have top knowledge of Ethereum: every detail of how your transaction will be picked up, tracing transactions in-depth, how to be the most gas efficient as possible to be able to spend a higher gas price than others and still profit.

Why? Because that "industry" is by far the most competitive when it comes to skills required to succeed. If you're not the absolute cream of the crop, you'll end up losing money by spending gas and getting beat out by other frontrunners. Normal developers, auditors, blahblah, don't have anywhere near the level of cutthroat competition that exists in frontrunning.
