Program Overview

ICHI is a self-sustaining, community governed platform that enables any other cryptocurrency community to create and govern their own in-house, non-custodial oneToken (a stablecoin valued at $1).

ICHI is the governance token of the ichi.org community and platform. It is hard capped at 5M tokens. Each ICHI is a vote on allowed oracles, collateral, investment strategies, etc in exchange for protocol governance rewards.

oneTokens are the governance tokens of specific oneToken systems. Each oneToken is a vote on treasury allocations, specific stablecoins parameters (like minting and redeeming fees), and on adoption programs.

More information about Ichi can be found on their website, https://www.ichi.org/.

This bug bounty program is focused around its smart contracts and is mostly concerned with the prevention of the loss of user funds.

Rewards by Threat Level

Rewards for Smart Contract vulnerabilities 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.

Payouts are handled by the ICHI team directly and are denominated in USD. However, payouts are done in USDC for rewards up to USD 10 000. For payouts greater, the reward is paid in xICHI. Critical payouts are done over a 6-month period distributed every month with the utilization of a Sablier contract

Assets in scope

Vulnerabilities affecting the four listed smart contracts are prioritized over the other smart contracts found on the GitHub link. Testnet smart contracts and other assets that are not smart contracts are not included in this bug bounty program.

Prioritized Vulnerabilities

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

  • Re-entrancy
  • Logic errors
    • including user authentication errors
  • Solidity/EVM details not considered
    • including integer over-/under-flow
    • including unhandled exceptions
  • Trusting trust/dependency vulnerabilities
    • 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
    • Signature malleability
    • Susceptibility to replay attacks
    • Weak randomness
    • Weak encryption
  • Susceptibility to block timestamp manipulation
  • Missing access controls / unprotected internal or debugging interfaces

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)
  • 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

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
