During the mint boom, collections revealed traits after minting, creating a brief window where fast rarity computation allowed buyers to sweep underpriced rare items before the market repriced. TraitSniper existed for that window and was among the fastest at it.
The mechanics
It monitors reveal transactions, computes rarity as metadata becomes available, and alerts on listings priced below rarity-implied value. Alerts can route to Discord or the app, and the speed advantage over manual checking is measured in seconds — which was the entire game.
Why it matters less now
Hyped reveals are rare, many collections now reveal at mint, and the pool of traders competing for that edge has shrunk with the market. The tool still works; the opportunity it exploits appears infrequently.
Cost
A free tier with delayed data, and paid plans for real-time access — which is the only tier that matters for its core use case, since delayed rarity data has no edge.
Who should use it
Traders who still participate in hyped mints and need reveal-speed data. For anything else, a free rarity lookup is sufficient.
