Open Web3 Stack is a common-good collection of libraries to accelerate application development on Substrate. It aims to provide application building blocks that are common for most specialist chains.
Open Web3 Stack contains the following repos
Open Runtime Module Library (ORML) where we implemented all the commonly used pallets, modules
Open-web3.js - frontend SDK for using extended Substrate logic from ORML
Guardian - a worker for monitoring and executing certain tasks
Rococo-community: a hosted environment for testing parachains and cross-chain communication
ORML

Guardian
With Guardian, with mere configuration, you can set up a number of automatic tasks for monitoring and executing commands for a chain of concern. A task can be monitoring margin positions with conditions (if collateral ratio < 110%) then trigger actions (e.g. post warning message to database service, or execute a script to add position).
Here're the examples and relevant documentation.
Open-web3.js
Open-web3 is a bunch of frontend packages that allow to interact with orml, indexer and oracles. Find out more here.
Community Rococo Testnet
We launched the community Rococo parachain testnet with shared infrastructure. It allows everyone to test cross-chain token transfers, running collators, validators, etc with lower overhead.
