A set of lightweight tools to operate and maintain a Cardano Stake Pool. Currently includes a leaderlog script based on BlockFrost (no need for working cardano-cli/cardano-node setup and less CPU/mem utilization) and a monitoring script to log relevant metrics directly into a text file in human-readable form (less complex and more resource-efficient than Grafana).
Oracle submitting information using Cardano Metadata
This is a Typescript/Javascript version of the cardano-addresses API. It includes a web demo.
A quickstart and boilerplate code to connect dApps with Web wallets using the latest cardano-serialization-lib. It includes examples with how to lock ADA and Tokens (NFTs) at a plutus script address and then how to redeem them from the plutus script address ... All from the front end. The project is bootstrapped with a Create React App, so is quick to get started for those familiar with this front end framework
