Program Overview

BarnBridge is a risk tokenization protocol. It aims to reduce the risks associated with DeFi, such as interest rate fluctuations and asset price volatility. By letting users select a risk profile, BarnBridge can redistribute risk via tokenized, liquid tranches. BarnBridge does this with its SMART Yield, SMART Exposure, and upcoming SMART Alpha products, all of which address a specific DeFi risk category.

The continued development of the dApps is governed by the community through the BarnBridge DAO.

For more information about BarnBridge, please visit https://barnbridge.com/.

The bug bounty program covers its smart contracts and is focused on preventing the following impacts:

  • Thefts and freezing of SMART Yield capital
  • Thefts and freezing of SMART Exposure capital
  • Thefts and freezing of SMART Alpha (to be launched in September 2021) capital
  • Thefts and freezing of future applications’ capital
  • Theft and freezing of DAO treasury funds
  • Theft and freezing of Governance Staking vault (e.g. “Barn” smart contract)

Rewards by Threat Level

Rewards 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.

All smart contract vulnerabilities are required to have a PoC for the consideration of a reward.

Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into account the funds at risk. Other considerations such as PR and branding concerns may also be considered by the team at its discretion.

Payouts up to USD 250 000 are handled by the BarnBridge team directly and are denominated in USD. Payouts under USD 1 000 are paid in a stablecoin at the discretion of the team. For larger payouts up to USD 250 000, the reward is split in a 80:20 BOND:stablecoin mix, where the team also decides on the stablecoin to be used.
