Program Overview

At CelsiusX, one of our goals is to bridge DeFi and CeFi infrastructure. Although DeFi, which is a major technological leap in financial infrastructure, enables services such as lending, borrowing, trading, and payments to be accessible to anyone in the world with an internet connection, it still faces many challenges when it comes to adoption, particularly because many innovative solutions fail to bootstrap sufficient liquidity.

As a DeFi-CeFi hybrid institution, CelsiusX is building liquidity bridges which will give users the ability to move assets between blockchains and provide cross-chain liquidity. For more information about CelsiusX, please visit https://celsiusx.io/. This bug bounty program is focused on smart contracts and preventing:

  • Thefts and freezing of wrapped tokens of any amount
  • Malfunction of any part of the smart contract system

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System and the CelciusX bug bounty reward classification (see Impacts in Scope). 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 bug reports require a PoC demonstrating how the vulnerability can be exploited and a suggestion for a fix to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required. This may be a smart contract itself or a transaction.

Critical smart contract vulnerabilities are capped at 5% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. There is no minimum reward for Critical vulnerabilities.

The following vulnerabilities are not eligible for a reward:

CelsiusX requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. Bounty Hunters will need an active (KYC'ed) account with Celsius Network and a proof of address. Security and Compliance review will be done before reward payouts. Rewards will be placed on the bug bounty hunter’s account with Celsius Network. The bug bounty hunter will open an account with Celsius network and successfully complete the KYC process. The collection of this information will be done by the Celsius Network team.

Payouts are handled by the CelsiusX team directly and are denominated in USD. However, payouts are done in USDC. Payouts will be remitted linearly over a period of up to 6 months.

Assets in scope

All CelsiusX smart contracts can be found at https://github.com/CelsiusXDeFi. 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.

Smart Contracts/Blockchain

  • Wrapped

    • Taking actions or changing privileges by unauthorized users:
    • Upgrading the implementation contract (Critical)
    • Upgrading the Oracle Address (Critical)
    • Minting (Critical)
    • Burning (Critical)
    • Pausing (High)
    • Revoking (High)
    • Whitelisting (High)
    • Blacklisting (High)
    • Unauthorized transfer of Wrapped token (Critical)
    • Minting more tokens than reported by the Oracle on any given block (not including flash loan) (Critical)
      • Unauthorized withdrawal of Ether or token held by a contract (Medium)
  • CollateralManager

    • Taking actions or changing privileges by unauthorized users:
      • Upgrading the implementation contract (Critical)
      • Modifying the data used to report reserved quantity (Critical)
  • AddressManager

    • Taking actions or changing privileges by unauthorized users:
      • Upgrading the implementation contract (Critical)
      • Modifying the data used to report addresses for reading reserve values (Critical)

In case of discrepancy between Immunefi Vulnerability Severity Classification System and CelsiusX’s classification above, CelsiusX classification will be followed.

Out of Scope & Rules

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
  • Centralization risks

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
