Program Overview

Tempus is a future yield tokenization and fixed rate protocol.

Most forms of yield farming return a variable rate of yield. This means that depositors can be subject to unpredictable fluctuations in their returns. Currently, there is no easy capital-efficient way to obtain a fixed yield or otherwise speculate on the receivable rewards.

This is where Tempus steps in. Tempus has three different use cases, each of which offers a unique value proposition:

  • Fix your future yield using any supported Yield Bearing Token (such as stETH, cDai).
  • Speculate on the rate of future yield of any supported Yield Bearing Token.
  • Provide liquidity to earn additional swap fees (on top of yield earned through yield farming protocols) by depositing any supported Yield Bearing Token.

For more information about Tempus, please visit https://tempus.finance/.

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

  • Thefts and freezing of principal of any amount
  • Thefts and freezing of unclaimed yield of any amount
  • Theft of governance funds
  • Governance activity disruption
  • Leak of user data
  • Deletion of user data
  • Redirected funds by address modification
  • Website goes down

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 web/app bug reports must come with a PoC in order to be considered for a reward. All Critical/High smart contract bug reports must come with a PoC in order to be considered for a reward.

Critical vulnerabilities are further capped at 10% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team. This applies to both Smart Contract and Web/App rewards. However, there is a minimum of USD 50 000 for Critical smart contract bug reports and USD 10 000 for Critical Web/App bug reports.

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