Developer shares latency lessons from 11,717 trades on Polymarket's on-chain betting platform

·2 views

A developer building an automated trading bot for Polymarket, a blockchain-based prediction market, documented execution latency insights after completing over 11,700 trades. Unlike centralized exchanges where microsecond speed is decisive, Polymarket's on-chain architecture on Polygon means client-side optimizations have limited impact since on-chain confirmation alone takes one to three seconds. The bot's execution pipeline spans four stages: signal generation (50–200ms), order signing (10–50ms), CLOB API submission (100–400ms), and on-chain confirmation (1–3 seconds). Key optimizations included running the bot on a US East VPS to reduce API round trips, maintaining persistent HTTP connections to avoid TCP handshake overhead, and pre-building order templates to cut signing time. The developer concluded that the core challenge on Polymarket is not raw speed but structuring execution so that unavoidable on-chain delays do not undermine otherwise viable trades.

Three Free Ways to Read Substack Newsletters on Your Kindle

Kindle's e-ink display offers a better reading experience than email inboxes, but Substack lacks a built-in 'send to Kindle' feature. The simplest workaround uses Amazon's personal Kindle email address, where forwarding a newsletter from an approved sender delivers it to the device within minutes. A second option involves saving individual Substack posts as PDFs via the browser's print function and emailing or uploading them to the Kindle, though PDFs do not reflow with font size changes. A third approach, suited to readers following multiple newsletters, uses an aggregator service that collects and ranks incoming issues weekly before sending a single curated document to the Kindle. Each method is free, with trade-offs around manual effort, formatting quality, and the number of subscriptions being managed.

Developer Ships First Public Project After Abandoning Four Prototypes in Four Months

Basit Jumani, an indie developer, spent four months building four different project prototypes, none of which he released to users. He attributed the repeated abandonment to perfectionism rather than flaws in the ideas themselves. He has now launched a simple web tool that allows users to upload photos, apply color grading presets, and download the results. The app was built using free tiers of ChatGPT and Lovable and is hosted on Lovable's free domain due to budget constraints. Jumani is publicly seeking user feedback to improve the product and continue his development journey.

UnityNets Launches Passion Bridge to Connect People Across Borders via AI

Passion Bridge is a new feature built into the UnityNets platform that uses Google's Gemini AI to find shared emotional or cultural threads between users from different countries. When a user submits a personal passion, a Supabase Edge Function forwards it alongside entries from other countries to the Gemini API, which identifies genuine underlying connections rather than simple keyword matches. The AI then generates a short 'unity message' explaining the link in an inspiring tone, which is displayed as a card in a community feed filterable by country. Successful matches contribute to UnityNets' existing Trust Score system, incentivising users to participate in building cross-border connections. The project was submitted to the Best Use of Google AI prize category, with the Gemini API serving as the core engine of the feature.
