The bug bounty program covers its website and is focused on the prevention of:

  • Theft of user deposits
  • Governance activity disruption
  • Website goes down
  • Leak of user data

Rewards by threat level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit. 

Website and Apps

CriticalUSD 5 000 - USD 20 000
High USD 1 000 - USD 3 000
MediumUSD 200 - USD 1 000
LowUSD 50 - USD 200

Bug reports must come with the following in order to be considered for a reward:

Proof of Concept (PoC) - All bug reports

Suggestions for a fix - Critical, High, and Medium reports only 

Under this bug bounty program, anything involving KYC data theft or leakage is considered as Critical. Additionally, anything involving user or company asset loss is also considered as Critical.

The USD 20 000 reward for critical vulnerabilities is only applicable if KYC data is stolen in an unencrypted format. All other critical vulnerabilities are capped at USD 5 000.

The final reward amount is determined by the AscendEX team by the exploitability of the vulnerability as well as its potential economic impact. 

Payouts are handled by the AscendEX team directly and are denominated in USD. All payouts are done in USDT.

  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Attacks requiring privileged access from within the organization
  • Feature requests
  • Best practices

The following activities are prohibited by bug bounty program:

  • Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
