Origin Dollar (OUSD)

Created by cryptocurrency and fintech veterans, the Origin Dollar is brought to you by the team at Origin Protocol that includes serial entrepreneurs, early cryptocurrency investors, early employees at YouTube, engineering managers at Google/Dropbox, and one of the Paypal co-founders, Yu Pan.

Origin Dollar (OUSD) is a new, fully backed stablecoin that was initially launched in September 2020 on the Ethereum network. Its design is superior to existing stablecoins because OUSD captures competitive yields while being passively held in wallets.

This bug bounty program is focused on their smart contracts and app and is focused on preventing:

• Loss of funds
• Loss of more than 10% of yield
• Freezing of funds that cannot be undone by admin actions
• Ability for an unauthorized user to use admin actions
• Governance process failures
• Redirected funds by address modification
• Shell access on server
• Injection of text
• Ability to have other users run arbitrary code on the site

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.

All Smart Contract and Web/app bug reports must come with a PoC in order to be considered for a reward.

The known issues listed below are considered out of scope:

• All issues found in their past audits here: https://docs.ousd.com/security-and-risks/audits

• OUSD does not guarantee which stablecoins will make up the backing stablecoins nor the value of those backing stable coins. Attacks which only change the mix of stablecoins, but do not reduce the total number of stablecoins held are excluded.

• Reductions in the number of backing stablecoins due to governance or strategist actions that move coins into or out of strategies, where the reduction comes from the normal fees of the underlying strategy or the price difference of stablecoins being moved in or out are excluded.

Critical vulnerabilities are further capped at 10% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team. However, there is a minimum of USD 50 000 for Critical bug reports on smart contracts.

Payouts are handled by the Origin Protocol team directly and are denominated in USD. However, payouts are done in OUSD.

In addition, the current implementation contracts of all the listed proxy contracts are in scope.

All smart contracts of Origin Dollar can be found at https://github.com/OriginProtocol/origin-dollar/tree/master/contracts/contracts. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Impacts in Scope

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

• Attacks requiring access to leaked keys/credentials
• Attacks requiring access to privileged addresses (governance, strategist)

Smart Contracts and Blockchain

• Incorrect data supplied by third party oracles
  • Not to exclude oracle manipulation/flash loan attacks
• Basic economic governance attacks (e.g. 51% attack)
• Lack of liquidity
• Best practice critiques
• Sybil attacks

Websites and Apps

• Theoretical vulnerabilities without any proof or demonstration
• Content spoofing / Text injection issues
• Self-XSS
• Captcha bypass using OCR
• CSRF with no security impact (logout CSRF, change language, etc.)
• Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
• Server-side information disclosure such as IPs, server names, and most stack traces
• Vulnerabilities used to enumerate or confirm the existence of users or tenants
• Vulnerabilities requiring unlikely user actions
• URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
• 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 this bug bounty program:

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

• Attempting phishing or other social engineering attacks against our employees and/or customers
• Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
• Any denial of service attacks
• Automated testing of services that generates significant amounts of traffic
• Public disclosure of an unpatched vulnerability in an embargoed bounty
