dForce

dForce advocates for building an integrated and interoperable open finance protocol matrix covering lending (global liquidity pool, yield markets), assets (stablecoin, synthetic asset, etc), and trading (liquidity aggregator, AMM).

Features:

• Permission-less and open – everyone with internet access can participate.
• Non-custodial – minimal trust cost, users always have ownership over their crypoassets.
• Open-sourced – anyone can integrate with dForce and build your own product on top of our protocols.
• Decentralized – dForce (DF) token empowers the governance voting process.

dForce is backed by a number of world-class investors including CMBI (China Merchant Bank International), Multicoin Capital, and Huobi Capital. It is the world’s first open finance project powered by a leading commercial bank.

Further resources regarding the dForce can be found on their website, https://dforce.network/.

The bug bounty program is focused around its smart contracts and infrastructure and is mostly concerned with issues stated in the Impacts in Scope section.

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 bug reports must come with a PoC in order to be considered for a reward, bug reports without a PoC will be rejected.

Critical vulnerabilities for smart contracts are further defined by the following conditions. All need to be met in order to get the classification of critical.

• Allow attacker(s) to take away collateral tokens for at least 10% in dollar value of collateral tokens from the system.
• Are applied to a real situation and triggered through an attack vector rather than theory or hypothesis.
• Occur in operation mode or emergency shutdown mode, excluding those occurring during or shortly after the deployment when the system is yet to become fully activated.

Please note this Bug Bounty Program does not cover vulnerabilities pertaining to 1) protocols built by third-party developers (i.e., smart contract wallet); 2) ownership of an admin key.

The reward of critical smart contract vulnerabilities is capped at 10% of economic damage, primarily taking into account the funds at risk. The dForce team may, at their discretion, decide to increase the reward based on PR and branding aspects.

Payouts are handled by the dForce team directly and are denominated in USD. However, payouts are done in DF.

In addition to the smart contracts in this table, the following information has been provided for reference. However, only the smart contracts in the table will be considered as in-scope:

• dForce Lending & Synthetic Assets: https://github.com/dforce-network/LendingContractsV2
• Farming: https://github.com/dforce-network/StakingV2

We are especially interested in receiving and rewarding vulnerabilities of the following types:

  • including composability vulnerabilities
• Oracle failure/manipulation
• Novel governance attacks
• Economic/financial attacks
  • including flash loan attacks
• Congestion and scalability
  • including running out of gas
  • including block stuffing
  • including susceptibility to frontrunning
• Consensus failures
• Cryptography problems

• Misleading Unicode text (e.g. using right to left override characters)

The following vulnerabilities are excluded from the rewards for this bug bounty program:

• Attacks that the reporter has already exploited themselves, leading to damage
• 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
• Any testing with pricing oracles or third party smart contracts
• 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
