It identifies the best way to contact an organization's security team so that hackers can report vulnerabilities directly to the organizations that can resolve them.\n\nThis document is a work in progress. We're happy to accept feedback, questions, or ideas for improvements. [File an issue](https://github.com/trailofbits/blockchain-security-contacts/issues/new) or [join us on Slack](https://slack.empirehacking.nyc/) to talk further.\n\n## Recommendations\n\n* Refer to [disclose.io](https://disclose.io/) for vulnerability disclosure program best practices\n* Don't make researchers [agree to terms](https://twitter.com/matthew_d_green/status/1025365194330066945) to report security issues to you\n* Create a security@ email address that delivers directly to your engineering team\n\n## Blockchains\n\n| Name | Contact | More info |\n| --- | --- | ---- |\n| Aptos |
