A month ago I had ideas for and but no dev team So I just started vibe coding Prayer times, petrol prices, ringgit tracker, flood alerts, cuti planner, a live PENGU dashboard with labeled whale wallets All shipped solo with AI Last week I thought of a cuti planner feature at 2am. By 7am it was live with support for all 16 states and calendar export. That used to take a sprint cycle minimum I spent years managing product teams and writing PRDs. Now I write prompts and ship before breakfast Vibe coding will not replace real engineering for complex infra. But for a solo founder who wants to validate fast and ship tools people actually use? Nothing else comes close right now 🚀

“Graduation Radar” What it does, live and free (no API keys, no wallet connection, zero risk to your funds): •Streams every new token via PumpPortal’s free WebSocket and tracks trades in real time •Scores each token 0–100: curve progress, buy pressure (3 min), unique wallets, age (filters bundled fake pumps), net SOL velocity, minus a penalty if the dev wallet sells •Alerts with sound + optional push notifications when a token crosses your threshold in the graduation runway, plus a separate alert when tokens actually graduate •Built-in paper trading — one-tap hypothetical buys, live P&L, win rate, and average return that persist between sessions How to use it: open the page, let it run 5–10 minutes to populate, hit “Test alert” to check sound, and paper trade the signals for a week or two. If the stats panel shows a real edge after ~100 signals (needs roughly +15% average to clear fees and slippage), then consider tiny real position

🎁 看直播,玩预测,赢周边 🎁 长鑫还在大 A 路演,HL 那边“股价”已经炒翻天! 是全球价格发现,还是没有股票的链上赌场? 你认可链上 Pre-IPO 给未上市公司提前定价吗? 近期,长鑫科技推进科创板 IPO,A 股发行价最终确定为 8.66 元。就在长鑫进行路演和申购期间, 已经通过 Hyperliquid 的 HIP-3 框架上线了 xyz:CXMT Pre-IPO 永续合约。 这个合约以 5 美元作为初始参考价,一度冲到 8.64 美元。看起来只是把 8.66 元换成了 8.64 美元,实际折算下来,链上价格已经接近 A 股发行价的 7 倍。 但需要注意,Hyperliquid 上交易的并不是长鑫股票。 持有 xyz:CXMT,没有 IPO 配售权、分红权或投票权,也不能在长鑫上市后兑换成真实 A 股。交易者只是在使用 USDC 和最高 5 倍杠杆,对“一股长鑫上市后值多少钱”进行做多或做空。 Hyperliquid 上的长鑫合约,是让全球资金提前参与中国硬科技定价? 还是在没有股票、没有交割的情况下,制造一场高杠杆价格游戏? SpaceX 没拿到股票,长鑫干脆不交股票。 这是链上 Pre-IPO 的产品进化? 还是“金融平权”叙事的一次退化? 本期 非小号K博士侃币 深度开聊: 《长鑫还在大 A 路演,HL 那边“股价”已经炒翻天!是价格发现还是链上赌场?你认可链上 Pre-IPO 给未上市公司提前定价吗?》 ⏰ 时间:2026年7月20日(周一)21:30 (UTC+8) 🎥 直播入口: 📡 同步直播平台:非小号 | X | 币安广场 | 火币Live | 热币Live | Gate Live | YouTube | TikTok | Telegram | pumpkin | sidekick | Debox 请锁定以上任一 TalkingWeb3/非小号 官方频道,或关注 TG 获取全部直播链接! 本期主持人: 👨🏫Ken博士 @ken_fxh - 非小号掌门人 👨🏫十三亿.Luffy @xiayi_web3 - luffy社区 👨🏫林野 @yu56413 常驻嘉宾: 👑 非小号 @fxh_crypto 👑 方宏进 @fang_herbert 👑 Dr
