Shell Protocol
Submit a BugProgram Overview
The objective of the Shell Protocol is to create an internet monetary system using stablecoins as building blocks. The first release is a liquidity pool optimized for stablecoin-to-stablecoin trades. It has weights, deep liquidity, protections against a broken peg and dynamic fees.
The bug bounty program is focused around its smart contracts and the prevention of loss of user funds.
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 and app bug reports must come with a PoC. Bug reports that do not include a PoC are rejected with instructions to provide PoC.
Payouts are handled by the Shell Protocol team directly and are denominated in USD. Payouts are done in USDC.
There is an additional TOKEN bonus once token is live for smart contract vulnerabilities over $50,000.
