ICON

ICON is an open-source layer 1 delegated proof-of-stake (DPoS) blockchain and smart contract platform focused on connecting unique blockchains and their respective communities. ICON’s Blockchain Transmission Protocol (BTP) is a trustless and chain-agnostic interoperability solution that supports generic smart contract calls between connected blockchains. ICON offers a unique high-performance smart contract execution environment powered by the Java Virtual Machine (JVM) that is ideal for developing minimal-latency cross-chain dApps. The ICON blockchain is governed by validators elected through the network’s ICX staking and delegation mechanism.

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.3 This is a simplified 4-level scale, with separate scales for websites/apps, smart contracts, and blockchains/Distributed Ledger Technologies (DLTs), focusing on the impact of the vulnerability reported.

All High and Critical Blockchain/DLT and Smart Contract bug reports require a Proof of Concept (PoC) to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.

ICON requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. If the entity is an individual, the information needed are Name, Address, Nationality, Birthday, copy of ID card, copy of residence certificate, criminal records and personal relations with politicians. If the entity is a company, business start date, address, country the business base on, copy of business certificate. And some information about people who have over 20% of the company's share. The collection of this information will be done by the ICON project team.

To determine the final reward amount, the likelihood to have a meaningful impact on availability, integrity, and/or loss of funds is considered. The final decision on the payout amount will be determined by the ICON team at its discretion.

Payouts are handled by the ICON team directly and are denominated in USD. However, payouts are done in ICX. If you disagree with the KYC requirement or you are denied by the KYC process, payouts cannot be done.

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
• Python smart contract deployment scenarios
• Http request issues such as rate limiting, throttling, timeouts, or anything else that can be resolved on the server

Scopes Temporarily Paused

When we receive a valid bug report, we update this section to allow our internal engineers time to investigate bugs in the same modules and scope. These scopes are paused for 4 weeks and then removed from the list.

Prohibited Activities

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
