Ask HN: How do you handle peer-to-peer discovery on iOS without a server?
5 by redgridtactical | 5 comments on Hacker News.
I'm building an app that syncs between phones over Bluetooth when there's no cell service. Android has Nearby Connections API which handles discovery and transport nicely. iOS has Multipeer Connectivity but it's flaky and Apple hasn't updated it in years. CoreBluetooth works but discovery is slow and you're limited to advertising 28 bytes. Has anyone found a reliable cross-platform approach to BLE device discovery that doesn't require a central server or pre-shared identifiers?

New ask Hacker News story: EVM-UI – visual tool to interact with EVM-based smart contracts

EVM-UI – visual tool to interact with EVM-based smart contracts 21 by magnusgraviti | 8 comments on Hacker News. Hey HN! We've built https://evm-ui.com, a free tool that allows you to interact with smart contracts visually. It started as an internal project while building Web3 apps for clients — we needed something more flexible and lightweight than Remix or Etherscan's UI. Unlike Etherscan or Polygonscan, you don't need to verify and open-source your smart contract to get a working UI. Paste the ABI (or load it from a template) and proceed. With EVM-UI, you can - Import contracts by address + ABI, or paste ABIs directly - Read/write functions with auto-generated UI (supports all Solidity types, including arrays) - Execute actions with smart inputs (dropdowns, min/max helpers, etc.) - Switch between EVM chains, testnets, or local RPCs within one workspace - Use developer tools (Keccak256, ABI encoder/decoder, address utils) - Share environments with your team and your cl...

New ask Hacker News story: Ask HN: Should I quit my startup journey for now?

Ask HN: Should I quit my startup journey for now? 2 by lkuebler | 4 comments on Hacker News. One year ago I started as an intern at a start-up. Things evolved and we are now a team of two-founders and one developer (me). We are running out of money and so my bosses chose to not pay themselves and myself a salary. What can I do to get reimbursed for my work at the startup? Currently there's not much work for me but if the other two guys manage to close the ongoing funding round in approx. 3 months they want to hire me full-time. Can I demand equity from them in advance to assure my piece of the cake once the money has arrived? The answer they gave me to this was they would give me the shares once the round is closed. But this is only good for them, not for me. Right? I am very new to start-up things and really don't know how to act. Feel free to share your experiences with getting shares as one of the first employees in a start-up.
