OpenZeppelin Defender provides a security operations (SecOps) platform for Ethereum with built-in best practices. Development teams implement Defender to ship faster and minimize security risks.
Signing up to Defender is free! Just head over to defender.openzeppelin.com, hit Sign In, and choose to create a new account. After verifying your email address, you will be redirected to your own Defender account on the free plan. See below for how to invite more users to your team!
Automate your Ethereum operations to deliver high-quality products faster with lower risk to users. Learn more about each component by clicking on its card.
All Defender components, where applicable, provide support for the Ethereum Mainnet, as well as the Rinkeby, Ropsten, Kovan, and Goerli test networks, plus the xDai sidechain. Support for Sokol is coming soon. Note that some networks may be unavailable depending on your plan.
If there is any other network or layer-2 solution you would like to use from Defender, please reach out to us!
The Defender free plan is restricted for testnet access only. In addition, you may only create up to five Relayers and Autotasks, import up to five Contracts into Admin, and have up to five Users in your team. The total number of transactions sent from Relayers cannot exceed 30 per hour, and the same limit applies for Autotask runs.
If you want access to Mainnet or xDai, or to increase any of the quota limits from the free plan, please apply via this form and we’ll reach out to you.
Access to all resources in Defender is shared across all users in your team. This means that every Relayer or Autotask you have created will also be accessible by any of your team members — there is no concept of user-based ownership.
You can review your team members under the Collaborators section, accessible from the top-right user menu. You can also invite new users to your team from there. A user can only belong to a single team in Defender (for now).
|If you want to add a user to your team, make sure to invite them from the Collaborators section. If they sign up directly to the application, they will be added to a new team of their own instead. If this happens, contact us at firstname.lastname@example.org and we’ll help.|
We strongly suggest that you enable 2FA to improve your Defender account security. As a second authentication factor, Defender relies on the Time-based One-Time Password standard (TOTP). To enable 2FA on Defender, you need a TOTP compliant application, such as Authy or Google Authenticator. You can enable 2FA under the Account settings section, accessible from the top-right user menu. Defender will guide you through the necessary steps.
As a Defender user, your feedback is important! We are committed to making Defender a product that will help you in the secure management of your project, and we cannot do that without your input. Feel free to reach out with questions, feature requests, or issues, either via the Community Forum, Telegram, or at email@example.com.
