Evolution of Non‑Fungible Tokens (NFTs)

This Dev.to article traces the history and development of non‑fungible tokens (NFTs), describing four stages: the Colored Coins precursor (2012–2013); the 2014 Quantum artwork by Kevin McCoy and Anil Dash often cited as the first NFT; the 2015–2017 expansion driven by Ethereum, smart contracts, projects like CryptoPunks and CryptoKitties, and the ERC‑721 standard (2017); and mainstream adoption from 2018 onward with marketplaces such as OpenSea. The piece lists current NFT use cases (art, music royalties, gaming assets, virtual real estate, identity, IP protection) and notes challenges like market volatility and environmental concerns. The author also mentions a hackathon project, Afyachain, applying NFTs to decentralized patient data.

Noscroll launches AI bot to do your doomscrolling

Noscroll, a new consumer startup, launched an AI-powered agent that reads social feeds, news sites and other online sources and sends users curated news digests via text. Built by Nadav Hollander (previously CTO at OpenSea) with an open-source developer known as @z0age, the service lets users connect their X account and other sources, specify topics to follow or ignore, and receive summaries at configurable cadences. Noscroll uses off-the-shelf AI models running on the company’s proprietary infrastructure, pulls from X, news sites, Reddit, Hacker News, Substack and research papers, and supports conversational follow-ups. The bot debuted publicly in late April 2026, offers a free sample digest and a $9.99/month subscription, and reportedly has attracted user adoption and inbound investor interest.

Integrating MoonPay API for Fiat On‑Ramp/Off‑Ramp

This developer guide explains end-to-end integration of MoonPay’s fiat-to-crypto and crypto-to-fiat gateway. It describes two integration paths (MoonPay-hosted Ramps widget/SDK for fastest launch or direct REST API for full control), account setup (sandbox vs production), creating HMAC-SHA256-signed widget URLs, verifying HMAC-signed webhooks, core endpoints (currencies, quotes, transactions, webhooks), NFT payment support, and off-ramp flows requiring a refundWalletAddress. The article documents pricing (card fees 3.5%–4.5% with a $3.99 minimum; bank transfers ~1%–1.9%; network fees passed through), rate limits (~100 requests/min per API key), common error codes, and testing recommendations using Apidog. It emphasizes trusting signed webhooks for transaction state and using sandbox for full end-to-end testing before production.
