Stop Using Tickers as Asset IDs. USDT on Bitcoin Just Made It Worse

·8 views

This month, Utexo, a Tether-backed company, plans to launch USDT natively on Bitcoin using the RGB protocol, with Lightning support to follow. Once it does, "USDT on Bitcoin" will refer to at least four different things: Omni (the 2014 original), Liquid, Lightning via Taproot Assets, and RGB. If your system identifies assets by ticker, or even by ticker + chain, that's a data model problem waiting to happen. Most codebases start like this: type Asset = "BTC" | "ETH" | "USDT" | "USDC"; Then multi-chain support arrives: type Asset = { symbol: string; chain: string }; // { symbol: "USDT", chain:

React native -> native

Hey everyone! 👋 I’m exploring an idea around React Native → Native development — basically helping RN developers understand what happens under the hood and get more comfortable with iOS/Android native concepts. I’ve made a very early version of the website: React native -> native If you get a minute, please check it out and fill the small feedback form on the website. Your honest feedback will genuinely help me decide whether to keep going with this. ❤️

Study Mate

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend I built StudyNotes – Student Learning Hub, a lightweight, responsive, and distraction-free study portal designed for my college friend and roommate, Alex. Alex is an undergraduate student preparing for rigorous semester examinations. Like many learners, they were constantly overwhelmed by multi-hundred-page lecture slides, fragmented group chat notes, and bloated educational platforms filled with pop-up ads, trackers, and mandatory login walls. StudyNotes solves this problem by serving as an instant, zero-friction

I’m building VaydeNet, an embedded communication framework — testers wanted

Switching radios often means rewriting communication code. I’m building VaydeNet to make that easier: a shared communication layer that keeps application logic separate from the underlying transport. The long-term goal is to support technologies such as ESP-NOW, LoRa, Bluetooth, Wi-Fi, and Ethernet through a consistent interface. The current prototype focuses on ESP32 and ESP-NOW. Its portable C++ engine validates packets, decodes incoming messages, delivers them to application code, and handles outgoing broadcast messages.
