StaFi: rDEX

rDEX V1 is an AMM DEX developed by StaFi that seeks to solve the liquidity problems associated with rTokens, the staking derivatives issued by StaFi. It will provide decentralized transaction services for all rTokens based on the StaFi Chain. Being an important part of the StaFi rToken ecosystem, rDEX V1 now is deployed on the StaFi chain, which is Substrate-based.

Rewards

StaFi: rDEX provides rewards in FIS on StaFi chain, denominated in USD.

Rewards by Threat Level

Smart Contract
Critical
USD $25,000
High
USD $5,000

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. 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 suggestion for a fix to be considered for a reward.

All known issues highlighted in the following audit report are considered out-of-scope:

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

Program Overview

rDEX V1 is an AMM DEX developed by StaFi that seeks to solve the liquidity problems associated with rTokens, the staking derivatives issued by StaFi. It will provide decentralized transaction services for all rTokens based on the StaFi Chain. Being an important part of the StaFi rToken ecosystem, rDEX V1 now is deployed on the StaFi chain, which is Substrate-based. Native rTokens minted by users can directly be traded through the rDEX for better liquidity.

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

  • The potential bugs or exploits in the slippage-based fee model and CLP liquidity pool model
  • The potential bugs or exploits in the liquidity mining contracts
  • Loss of user funds staked (principal) by freezing or theft
  • Theft of unclaimed yield
  • Freezing of unclaimed yield
  • Temporary freezing of funds for at least 2 days
  • Smart contract gas drainage
  • Block stuffing without fund transfers blocked

KYC not required

No KYC information is required for payout processing.

Proof of Concept

Proof of concept is always required for all severities.

Prohibited Activities

Default prohibited activities
  • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
  • 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 that are executed against project assets
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
  • Any other actions prohibited by the Immunefi Rules

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity. Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
