About

Watches your open Clanker snipe positions and auto-sells the moment your take-profit or stop-loss threshold hits. Pricing comes from a live 0x DEX quote, so it works even for new tokens that haven't shown up on CoinGecko yet. Your profits land in whatever token and chain you pick

Use it with the Clanker Launch Sniper template - snipe with that one, exit with this one

Quick Setup:

Import your wallet or use your B3OS Treasury Wallet
Pick the Slack channel for sell notifications
Set your take-profit eg 3 means sell when the position is worth 3× what you paid (200% gain)
Set your stop-loss eg 0.5 means sell when the position drops to half its buy price (50% loss)
Choose the chain and token you want your sell profits in (default: USDC on Base)
Test and publish
