Binance is the number one cryptocurrency exchange, operating in many places throughout the world. Specializing in crypto-to-crypto transactions, we provide access to hundreds of digital currency pairs. As a leading exchange platform, we prioritize security, liquidity, and speed, while maintaining some of the lowest fees in the industry. We strive to give our users the best experience possible, also providing access to some of the latest blockchain/DLT technologies available, with new cryptocurrencies being listed frequently.
Binance stands for “Binary Finance”, integrating digital technology with finance. Just as the name suggests, we are digital currency enthusiasts, with more than 20 years of combined finance, security, and development experience at top exchange platforms and companies including the Tokyo Stock Exchange, Morgan Stanley, Accenture, and other Top 100 companies from all over the world.
At Binance, the security of our users is our number one priority. As such, we strive to provide the most secure platform possible. We will evaluate reported security issues based on the security impact to our users and the Binance ecosystem.
This bounty brief describes the rules of the Binance bug bounty program, as well as the eligibility of vulnerabilities and the rewards.
This program adheres to the Bugcrowd Vulnerability Rating Taxonomy for the prioritization/rating of findings.
Rewards will be paid out in BNB (Binance Coin).
Once your submission is accepted, please provide either of the following to receive your reward.
- email address registered on Binance
- your BNB wallet address
We suggest researchers create a separate private Binance account, or a BNB wallet.
*Prices will change with the cryptocurrency markets and the dollar amount listed below could change.
Please note that only vulnerabilities with a working proof of concept that shows how it can be exploited will be considered eligible for monetary rewards.
*Binance is eager to work with the community to make sure that every researcher's finding is rewarded fairly - based on the vulnerability's impact on business and overall severity. To this end, it is possible that extraordinarily severe issues or those with extreme impact may be rewarded up to $100,000.
Binance may award an additional reward bonus for exceptional reports. This will be done at Binance's discretion .

Actions to avoid:
- Testing on accounts other than those that you own
- Automated testing using tools such as scanners
- Excessive request attempts
- Destruction of data
Ineligible issues (Will be closed as out of scope):

- Internally known issues, duplicate issues, or issues which have already been made public
- Vulnerabilities only exploitable on out-of-date browsers or platforms
- Vulnerabilities related to auto-fill web forms
- Use of known vulnerable libraries without actual proof of concept

- Issues related to unsafe SSL/TLS cipher suites or protocol version
- Content spoofing
- Cache-control related issues
- Exposure of internal IP address or domains
- Missing security headers that do not lead to direct exploitation
