Interact with any third parties (which includes modifying or accessing data from such third party) if such third party has not consented to such action;

Exploit any of the Vulnerabilities you discover in any way for any reason, including exploitation of any data uncovered by way of such Vulnerability;

Engage in social engineering (including “phishing”) of Nervos staff or contractors;

Make a good faith effort to avoid privacy violations and disruptions to others, including but not limited to unauthorized access to or destruction of data, theft, and interruption or degradation of our services. Nervos reserves the right, in its sole discretion, to exclude certain categories of bugs or vulnerabilities from any reward in the Nervos Bounty Program.

Submission Process If you discover a vulnerability, please provide a report of the Vulnerability to Nervos at bounty@nervos.org and include your name, email address, company name (if applicable), a description of the bug, including your estimation of the potential impact to Nervos, and a description of the steps you took to identify the vulnerability. Properly submitted and documented in accordance with the submission process above and the Nervos Bounty Program Guide;

The first such Submission for the given Vulnerability. Submissions will be reviewed by our security team. We aim to provide a response within a few days after receiving a Submission, but responses may be delayed based on the availability of the security reviewer and whether there are other more severe Vulnerabilities that our security team is currently addressing. If Nervos, in its sole discretion, determines that your Submission meets the criteria described above and that the Submission is the first for the given Vulnerability, Nervos will remit to you a reward, which depends on a number of factors, including but not limited to the type and severity of the Vulnerability, and as set forth in further detail in the Nervos Bounty Program Guide.

Rewards To be eligible to receive a reward, you must provide Nervos with accurate, complete and up-to-date information about you, including your name, email address, and any other information that Nervos reasonably requests, to allow Nervos to send a reward to you. If you are located within the United States, you may not be eligible to receive tokens as rewards. If you are not eligible to receive tokens as rewards, any and all rewards you receive will be paid in USD, USDT, ETH or BTC only. If you are located outside the United States, you have the option to receive rewards in CKB Tokens. Before you receive a reward, you must sign and return to Nervos any additional agreements or forms as may be required and provided by Nervos, including without limitation, the Notice of Future Token Interest Award if your reward will be paid in CKB tokens. Nervos makes no guarantee of a token’s value in any currencies. You are responsible for paying all taxes related to the rewards payments, if any.

By submitting a Submission, you hereby irrevocably assign to Nervos and agree to irrevocably assign to Nervos all of your right, title, and interest in and to the Submission, including without limitation all worldwide patent rights, copyright rights, trade secret rights, and other proprietary or intellectual property rights therein.
