Instead of polling nodes or maintaining a custom event indexer, you register a contract address or upload an ABI file, choose the events you care about, and Chainrel pushes matching events to a webhook URL you control. Predefined ERC-20, ERC-721 and ERC-1155 event templates speed up common token and NFT use cases. Supported networks include Ethereum, Polygon, Binance Smart Chain and Avalanche C-Chain, with Optimism and Linea marked as coming soon, and both mainnets and popular testnets are listed. The platform advertises processing of around 150,000 events per minute. Security-minded developers can set a block-confirmation threshold so notifications only fire once a transaction is considered safely settled, and factory-contract support lets you listen to events emitted by every child contract. Pricing uses a freemium model: a free Starter tier includes 500 notifications per month, one webhook and limited event/contract listening, while the Growth plan (around $19.90 per month billed annually) raises this to 100,000 notifications, 10 webhooks and more team seats. Overage notifications are billed per unit, and a custom plan is available. The company is based in Istanbul, Turkey. **Pricing & Plans:** Freemium. A free Starter tier gives 500 notifications/month and 1 webhook. Growth is roughly $19.90/month (billed annually, +VAT) for 100,000 notifications and 10 webhooks, with per-notification overage pricing and a custom enterprise option. - **Real-time blockchain webhooks:** Deliver smart contract events straight to your backend URL as JSON, so you avoid building and hosting your own indexer. - **Multi-chain EVM support:** Listen to events on Ethereum, Polygon, Binance Smart Chain and Avalanche C-Chain, with mainnet and testnet endpoints. - **ABI and contract import:** Subscribe using a verified contract address or ABI file, or pick from built-in ERC-20, ERC-721 and ERC-1155 event templates. - **Block confirmation safety:** Choose how many confirmations must pass before a notification is sent, protecting your workflow from blockchain reorganizations. - **Slack and Discord delivery:** Route alerts to chat channels in addition to webhooks, keeping product and ops teams informed without extra tooling. **Strengths:** Sends events to webhook, Slack or Discord without custom indexer code; Adjustable block-confirmation threshold guards against chain reorganizations; Factory contract support covers dynamically created child contracts; Free tier is enough to prototype, with simple usage-based overage pricing **Limitations:** Optimism and Linea were still marked 'coming soon' rather than live; Notification channels are limited to webhook, Slack and Discord, with Telegram and Zapier pending; Exceeding the notification quota pauses delivery until the next cycle or extra credits are bought [Profile (Markdown)](https://openaitools.app/tool/chainrel.md) ## Knowt Knowt is a study platform built around flashcards and AI study tools, and it markets itself as the leading free Quizlet alternative.

The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go.
