We are excited to bring you many new Defender features this month that add powerful functionality to your security operations – all fully included in your Defender account. We built Defender to provide you with a comprehensive platform to automate your smart contract operations, and with these updates you will be able to ship products faster than ever before with built-in security.
You can now start using automated emergency response with Defender Sentinels, a new feature that allows you to monitor and respond to smart contract functions and events. Most importantly, Sentinels acts as the connection point between all Defender features, allowing you to create automated tasks with Autotask based on abnormal activity, or get notifications about activity directly in Slack or Discord.
In addition to adding Sentinels, we’ve dramatically increased the functionality of existing features. For example, you can now pause smart contracts directly from Defender Admin and connect to both Admin and Autotasks directly via API to automatically create upgrade change proposals.
This is just the beginning of what we have planned for Defender, and we are looking forward to unveiling many new features in the coming months to help you streamline your Ethereum operations. To dive deeper into Sentinels, you can join our workshop today (Thursday, March 11th 12pm PT/3pm ET): Service Monitoring and Emergency Response with Defender
