Threshold Network

Threshold is the first ever on-chain merge between two existing networks and communities, Keep and NuCypher. The Threshold Network provides a suite of threshold cryptography products that power user sovereignty on the public blockchain. Threshold cryptography distributes sensitive operations across multiple independent entities, like nodes in a network. A successful operation requires a threshold or a minimum number of entities to cooperate. This simple idea increases security and availability and reduces reliance on trusted parties.Threshold is governed by a DAO whose parts hold separate responsibilities that are embedded in the governance structure. The Threshold DAO has two primary bodies: the Tokenholder DAO (based on the Governor Bravo governance model) and the Elected Council. The goal of this two-pronged structure is to enhance representation while ensuring accountability. Each governance body holds the other accountable, similar to the system of checks and balances found in most constitutional governments.

For Whitehats: It is highly recommended that you review the details of this program in full. Although many Bug Bounty programs have standard terms and conditions, each also has their own unique details that are critical to your success.

Prior to submitting a report please review the Immunefi Bug Report Template and Best Practices.

Please review how rewards are distributed based on the Immunefi Vulnerability Severity Classification System V2.3 This is a simplified 4-level scale system with separate scales for Smart Contracts and Websites/Apps.

Rewards for critical smart contract bug reports will be further capped at 10% of direct funds at risk if the bug discovered is exploited. However, there is a minimum reward of USD 10 000 and a max program cap of USD 500 000

Rewards for high smart contract bug reports will be further capped at 100% of direct funds at risk if the bug discovered is exploited. However, there is a minimum reward of USD 5 000 and a max cap of USD 50 000

Rewards for medium smart contract vulnerabilities with direct monetary impact are further capped at 100% of the funds at risk. However, there is a minimum reward of USD 1 000 and a max cap of USD 5 000

Rewards for critical web/app bug reports will be further capped at 10% of direct funds at risk if the bug discovered is exploited. However, there is a minimum reward of USD 5 000.

Rewards for high web/app bug reports will be further capped at 100% of direct funds at risk if the bug discovered is exploited. However, there is a minimum reward of USD 1 000.

Payouts and Payout Requirements

Payouts are handled by the Threshold DAO team directly and are denominated in USD. However, payouts are made in T. (https://www.coingecko.com/en/coins/threshold-network-token#markets).

The calculation of the net amount rewarded is based on the average price between high and low for the day of the report submission as published on CoinMarketCap.com Historical Data (https://coinmarketcap.com/currencies/threshold/historical-data/) for the T token. No adjustments are made based on liquidity availability. For avoidance of doubt, if the reward amount is USD 5 000 and the average price at the time of the bug report submission is USD 1.75 per token, then the reward will be 2857.142857 units of that token.

Threshold Network commits to honoring payouts according to the terms set out in this program at the time of report submission, and to treat this program as the agreement and source of truth concerning bug reports and responsible disclosures.

For the purposes of determining report validity, this is a Primacy of Rules program.

Learn more about report validity best practices here: Best Practice - Primacy of Impact vs Primacy of Rules.

Threshold Network would like to notify whitehats that payouts concerning high and critical reports may exceed the SLA established by Immunefi. These larger payouts could be delayed by a few hours or days, depending on the amount, to allow our governance process to fund the required payment, which can take up to 14 days. Threshold Network will inform the whitehat whenever this is the case, within the SLA timeframe, to manage expectations and provide clarity.

KYC Requirements:

Threshold Network does not have a Know Your Customer (KYC) requirement for bug bounty payouts.

Responsible Publication

Threshold adheres to category 2. This Policy determines what information whitehats are allowed to make public from their submitted bug reports. For more information about the category selected, please refer to our Responsible Publication page.

Audit Discoveries and Known Issues:

Bug reports covering previously-discovered bugs are not eligible for any reward through the bug bounty program. If a bug report covers a known issue, it may be rejected together with proof of the issue being known before escalation of the bug report via Immunefi.

Previous audits and known issues can be found at:

• https://leastauthority.com/blog/audits/audit-of-keep-network-tbtc-bridge-v2/
• https://www.certik.com/projects/threshold-network
• https://chainsecurity.com/security-audit/threshold-network/
• https://github.com/threshold-network/token-dashboard/issues
• https://github.com/threshold-network/solidity-contracts/issues
• https://github.com/keep-network/tbtc-v2/issues (refers to known issues related to tBTC v2 contracts)

Impacts only apply to assets in active use by the project like contracts on mainnet or web/app assets used in production. Any impact that applies to assets not in active use, like test or mock files, are out-of-scope of the bug bounty program unless explicitly mentioned as in-scope.

All reports must be submitted in English.

Smart Contracts

• Smart Contracts - PoC, Smart Contract bug reports are to include a runnable Proof of Concept (PoC) in order to prove impact.
• For more information on PoCs please visit: Proof of Concept (PoC) Guidelines and Rules
• All smart contracts of Threshold Network can be found at:
  • https://github.com/threshold-network
  • https://github.com/nucypher
  • https://github.com/keep-network

Web/App

• Web/App - Bug reports are to include a runnable Proof of Concept (PoC) in order to prove impact.
• All web/app bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. All PoC content must adhere to the PoC guidelines and rules of Immunefi. In the event that a PoC requires an attack on a web/app asset provided, they must still adhere to the rules provided, otherwise eligibility for a reward may be revoked.
• For more information on PoCs please visit: Proof of Concept (PoC) Guidelines and Rules
• All codes of Threshold Network can be found at: https://github.com/threshold-network/token-dashboard

Whitehats are highly encouraged to review any potential subdomains and what specific port(s) are in scope. Even though the domain may be the same, different ports may point to different assets.

Impacts to other assets

For the purposes of determining report validity, this is a Primacy of Rules program. However, hackers are encouraged to submit issues outside of the outlined Impacts and Assets in Scope.

If whitehats can demonstrate a critical impact on code in production for an asset not in scope, Threshold Network encourages you to submit your bug report and it will be assessed on a case-by-case basis.

Impacts in Scope

Impacts are based on the Immunefi Vulnerability Severity Classification System V2.3.

At Immunefi, we classify bugs on a simplified 4-level scale:

The following impacts and attack vectors are excluded from rewards by default for all Immunefi bug bounty programs:

• 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), except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
• Vulnerabilities requiring unlikely user actions

Smart Contracts and Blockchain/DLT

• Basic economic governance attacks (e.g. 51% attack)
