Program Overview

Port Finance aims to provide a whole suite of money market products. They aim to provide variable rate lending, fixed rate lending and also interest rate swap products. Their backers include Jump Capital, Alameda Research, Defi Alliance, a41 and founders of other Solana projects such as Mercurial, Solanium and Raydium.

They are the first variable rate lending product that is live on Solana. Currently, Port Finance supports 13 different assets from the Solana, Ethereum, Terra and Bitcoin networks.

In December 2021, they launched their first fixed rate lending product Sundial and they believe that the fixed rate lending protocol will unleash the true potential of the Solana blockchain by providing an effective interest rate discovery mechanism using Serum.

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

  • Loss of any user funds
  • Insolvency of the platform

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 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. However, there is a minimum of USD 50 000 for Critical bug reports.

Known issues highlighted in their previous audits linked below are considered out-of-scope:

Payouts are handled by the Port Finance team directly and are denominated in USD. However, payouts are done in USDC, PORT or a combination of both, at the discretion of the team.
