I was just watching a transaction in the mempool, and I honestly almost laughed in anger. When the network is congested, setting your gas a bit lower is basically handing your fate to someone else—miners just drop your transaction into the pending pool and it won’t budge for half the time. Mine was worse once: I set the nonce order wrong, and it got stuck in the queue—then all following transactions had to line up and wait for it to be processed. That feeling is like a big truck breaking down on the highway in front of you, and you can only stare blankly behind it.

Put simply, the mempool is like a little black room: your transaction gets squeezed in with a bunch of contract interactions and arbitrage bots. Sometimes you’ve clearly set a sufficient priority fee, but someone else’s more cunning MEV strategy can still snipe you. Anyway, I learned the hard way later—either use the quick-channel API, or keep a close eye on the block’s pending status and adjust manually.

Lately there’s been a lot of controversy over NFT royalties. I’ve seen plenty of creators, to protect their revenue, starting to implement on-chain “anti-snipe” designs—like dynamically adjusting royalty parameters to influence how mempool flow moves in the secondary market. Pfft, basically this road is dancing on the tip of a knife, but someone has to be the first to test it.
