Monex Trade Assistant

I built MonEx Trade Assistant so people can buy Nad.fun tokens on Monad from X. What I built: A live web (https://trade.monexmonad.xyz) + X bot (@monexmonad). Users log in with X, link a wallet once, fund a trading balance, then tweet: @monexmonad buy <amount> mon <token_address> The bot executes the buy from a custodial trading wallet and replies with spent/received. The app also supports in-app buy/sell, portfolio, and add funds / cash out. Problem: Buying a token mid-timeline usually means leaving X, finding the CA, connecting a wallet, switching networks, and swapping across multiple tabs. By the time you’re done, the moment is gone, the token reached a million cap. What I learned: X OAuth + custodial trading wallets on Monad need careful UX (setup once, then tweet). Success replies must avoid crypto-address restrictions on new X apps. App sells need approve + receipt confirmation so a reverted tx is never shown as success. After setup, users disconnect their browser wallet — the desk still has to show the linked balance and make reconnect obvious. Stack: Cloudflare Worker + Durable Objects, Next.js desk on Cloudflare, Monad mainnet, Nad.fun routers, X OAuth/API.
