This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.</p> <p>All web/app bug reports and Critical/High/Medium smart contract bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required. In addition, all Critical/High/Medium bug reports must come with a suggestion for a fix in order to be considered for a reward.</p> <p>The following known issues are considered to be out of scope of this bounty program:</p> <ul> <li>All issues highlighted previously in the following audit report: <ul> <li>Peckshield Audit for DeFi SDK (August, 2020): <a href="https://drive.google.com/file/d/158GG-J681xAc4d8pMibpP_SFJikX4HPM/view?usp=sharing&utm_source=immunefi" node="[object Object]" target="_blank" rel="noopener noreferrer">https://drive.google.com/file/d/158GG-J681xAc4d8pMibpP_SFJikX4HPM/view?usp=sharing</a></li> <li>Audit: <a href="https://github.com/zeriontech/defi-sdk/blob/interactive/audits/Zerion%20DeFi%20SDK%20Trail%20of%20Bits%20Audit%20Report.pdf?utm_source=immunefi" node="[object Object]" target="_blank" rel="noopener noreferrer">https://github.com/zeriontech/defi-sdk/blob/interactive/audits/Zerion%20DeFi%20SDK%20Trail%20of%20Bits%20Audit%20Report.pdf</a></li> </ul> </li> <li>External apps having integrations with Zerion</li> </ul> <p>Rewards for critical smart contract 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 reward of <strong>USD 10 000</strong> for Critical bug reports.</p> <p>Critical website and application bug reports will be rewarded with the full <strong>USD 15 000</strong> only if the impact leads to a direct loss in funds or a manipulation of the votes or the voting result, as well as the modification of its display leading to a misrepresentation of the result or vote. All other impacts that would be classified as Critical would be rewarded no more than <strong>USD 10 000</strong>.</p> <p>Zerion requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed is email address, full name, and country of residence.</p> <p>Payouts are handled by the <strong>Zerion</strong> team directly and are denominated in USD. However, payouts are done in <strong>USDC or DAI</strong>.</p></div></div></div><div class="text-center"><a class="inline-block rounded-full border border-[#D2D4D8] bg-[#E1E3E6] px-[24px] py-[8px] align-middle text-[16px] leading-[25px] text-black transition-colors hover:bg-white" href="/bug-bounty/zerion/scope/#impacts"><svg stroke="currentColor" fill="currentColor" stroke-width="0" viewBox="0 0 512 512" class="inline-block" height="1em" width="1em" xmlns="http://www.w3.org/2000/svg"><path fill="none" stroke-linecap="round" stroke-linejoin="round" stroke-width="32" d="M255.66 112c-77.94 0-157.89 45.11-220.83 135.33a16 16 0 0 0-.27 17.77C82.92 340.8 161.8 400 255.66 400c92.84 0 173.34-59.38 221.79-135.25a16.14 16.14 0 0 0 0-17.47C428.89 172.28 347.8 112 255.66 112z"></path><circle cx="256" cy="256" r="80" fill="none" stroke-miterlimit="10" stroke-width="32"></circle></svg> <span>View impacts in scope</span></a></div></section><section class="mb-[60px]"><div class="-mt-[75px] mb-[16px] flex flex-col pt-[75px] md:flex-row md:items-center md:justify-between"><h3 class="mb-[16px] text-[22px] leading-[33px] md:mb-0"><span class="flex items-center space-x-2"><svg stroke="currentColor" fill="none" stroke-width="2" viewBox="0 0 24 24" aria-hidden="true" height="28" width="28" xmlns="http://www.w3.org/2000/svg"><path stroke-linecap="round" stroke-linejoin="round" d="M9 12h6m-6 4h6m2 5H7a2 2 0 01-2-2V5a2 2 0 012-2h5.586a1 1 0 01.707.293l5.414 5.414a1 1 0 01.293.707V19a2 2 0 01-2 2z"></path></svg><span>Program Overview</span></span></h3></div><div class="relative overflow-hidden rounded-[5px] bg-[#191919] border border-[#374151] border-none"><div class="px-8 py-5"><div class="Markdown_markdown__63pVN prose"><p>At Zerion, we are on a mission to empower more people around the world with efficient, transparent, and censorship-resistant financial services.</p> <p>We do this by building applications, tools, and infrastructure enabling any smartphone holder, anywhere in the world, to build and manage their decentralized finance (DeFi) portfolios. The company was founded in 2016 by a technical team of crypto-native builders who sought to change the way centralized financial services work, primarily driven by experiencing the lack of financial opportunity within their countries.</p> <p>Zerion has grown to become one of the most popular DeFi interfaces in the world. Since inception, Zerion has processed over $1.4 billion in transaction volume and serves more than 200K monthly active users from over 217 countries.</p> <p>Zerion gives customers access to more than 50,000 digital assets, 60 protocols & all NFTs on the Ethereum blockchain through their app, which streamlines the UI of DeFi. Users can access tokens and invest through the app similar to exchanges like Coinbase or Gemini, but do so using their own personal wallets like MetaMask, meaning user funds and private keys aren’t controlled by or accessible to Zerion.</p> <p>For more information about Zerion, please visit <a href="https://zerion.io/?utm_source=immunefi" node="[object Object]" target="_blank" rel="noopener noreferrer">https://zerion.io/</a>.</p> <p>This bug bounty program is focused on their smart contracts, website and app and is focused on preventing:</p> <ul> <li>Loss of user funds</li> <li>Leak of user data</li> <li>Deletion of user data</li> </ul></div></div></div></section><section class="mb-[60px]"><div class="-mt-[75px] mb-[16px] flex flex-col pt-[75px] md:flex-row md:items-center md:justify-between"><h3 class="mb-[16px] text-[22px] leading-[33px] md:mb-0"><span class="flex items-center space-x-2"><svg stroke="currentColor" fill="currentColor" stroke-width="0" viewBox="0 0 24 24" height="28" width="28" xmlns="http://www.w3.org/2000/svg"><path d="M12 2.5a5.5 5.5 0 0 1 3.096 10.047 9.005 9.005 0 0 1 5.9 8.181.75.75 0 1 1-1.499.044 7.5 7.5 0 0 0-14.993 0 .75.75 0 0 1-1.5-.045 9.005 9.005 0 0 1 5.9-8.18A5.5 5.5 0 0 1 12 2.5ZM8 8a4 4 0 1 0 8 0 4 4 0 0 0-8 0Z"></path></svg><span>KYC required</span></span></h3></div><div class="relative overflow-hidden rounded-[5px] bg-[#191919] border border-[#374151]"><div class="px-8 py-5"><p>The submission of KYC information is a requirement for payout processing.</p></div></div></section><div class="grid"><section class="flex flex-col mb-[60px]"><div class="-mt-[75px] mb-[16px] flex flex-col pt-[75px] md:flex-row md:items-center md:justify-between"><h3 class="mb-[16px] text-[22px] leading-[33px] md:mb-0"><span class="flex items-center space-x-2"><svg stroke="currentColor" fill="currentColor" stroke-width="0" viewBox="0 0 512 512" height="24" width="24" xmlns="http://www.w3.org/2000/svg"><path d="M256 48a208 208 0 1 1 0 416 208 208 0 1 1 0-416zm0 464A256 256 0 1 0 256 0a256 256 0 1 0 0 512zM369 209c9.4-9.4 9.4-24.6 0-33.9s-24.6-9.4-33.9 0l-111 111-47-47c-9.4-9.4-24.6-9.4-33.9 0s-9.4 24.6 0 33.9l64 64c9.4 9.4 24.6 9.4 33.9 0L369 209z"></path></svg><span>Proof of Concept</span></span></h3></div><div class="group flex w-full flex-1 items-center justify-between gap-2 rounded-[5px] rounded-br-[5px] border border-[#374151] bg-[#1B1B1B] py-5 pl-8 pr-4 transition hover:cursor-pointer hover:border-[#67CCCD] hover:bg-[#000000]"><div class="max-w-[80%]"><p class="text-[18px] leading-[31px]">Proof of concept is always required for all severities.</p></div><svg stroke="currentColor" fill="currentColor" stroke-width="0" viewBox="0 0 20 20" aria-hidden="true" class="transition-color shrink-0 text-[#898E99] duration-200 group-hover:text-[#67CCCD]" height="18" width="18" xmlns="http://www.w3.org/2000/svg"><path fill-rule="evenodd" d="M18 10a8 8 0 1 1-16 0 8 8 0 0 1 16 0ZM8.94 6.94a.75.75 0 1 1-1.061-1.061 3 3 0 1 1 2.871 5.026v.345a.75.75 0 0 1-1.5 0v-.5c0-.72.57-1.172 1.081-1.287A1.5 1.5 0 1 0 8.94 6.94ZM10 15a1 1 0 1 0 0-2 1 1 0 0 0 0 2Z" clip-rule="evenodd"></path></svg></div></section></div><section class="mb-[60px]"><div class="-mt-[75px] mb-[16px] flex flex-col pt-[75px] md:flex-row md:items-center md:justify-between"><h3 class="mb-[16px] text-[22px] leading-[33px] md:mb-0"><span class="flex items-center space-x-2"><svg stroke="currentColor" fill="currentColor" stroke-width="0" viewBox="0 0 512 512" height="1em" width="1em" xmlns="http://www.w3.org/2000/svg"><path d="M256 8C119.034 8 8 119.033 8 256s111.034 248 248 248 248-111.034 248-248S392.967 8 256 8zm130.108 117.892c65.448 65.448 70 165.481 20.677 235.637L150.47 105.216c70.204-49.356 170.226-44.735 235.638 20.676zM125.892 386.108c-65.448-65.448-70-165.481-20.677-235.637L361.53 406.784c-70.203 49.356-170.226 44.736-235.638-20.676z"></path></svg><span>Prohibited Activities</span></span></h3></div><div class="relative overflow-hidden rounded-[5px] bg-[#191919] border border-[#374151]"><div class="flex"><div class="rounded-br-[5px] bg-[#374151] px-[10px] py-[2px] text-sm font-medium bg-[#374151]">Default prohibited activities</div></div><div class="px-8 py-5"><div class="Markdown_markdown__63pVN prose bounty_static__BF7KO"><ul> <li>Any testing on mainnet or public testnet deployed code;

In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.</p> <p>Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.</p> <ul> <li><a href="https://immunefisupport.zendesk.com/hc/en-us/articles/16913153448721-Chain-Rollbacks?utm_source=immunefi" node="[object Object]"

empower more people around the world with efficient, transparent, and censorship-resistant financial services. \n\nWe do this by building applications, tools, and infrastructure enabling any smartphone holder, anywhere in the world, to build and manage their decentralized finance (DeFi) portfolios. The company was founded in 2016 by a technical team of crypto-native builders who sought to change the way centralized financial services work, primarily driven by experiencing the lack of financial opportunity within their countries.\n\nZerion has grown to become one of the most popular DeFi interfaces in the world. Since inception, Zerion has processed over $1.4 billion in transaction volume and serves more than 200K monthly active users from over 217 countries.\n\nZerion gives customers access to more than 50,000 digital assets, 60 protocols \u0026 all NFTs on the Ethereum blockchain through their app, which streamlines the UI of DeFi. Users can access tokens and invest through the app similar to exchanges like Coinbase or Gemini, but do so using their own personal wallets like MetaMask, meaning user funds and private keys aren’t controlled by or accessible to Zerion.\n\nFor more information about Zerion, please visit [https://zerion.io/](https://zerion.io/). \n\nThis bug bounty program is focused on their smart contracts, website and app and is focused on preventing:\n\n - Loss of user funds\n - Leak of user data\n - Deletion of user data","prioritizedVulnerabilities":"__Impacts in Scope__\n\nOnly the following impacts are accepted within this bug bounty program.

This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.\n\nAll web/app bug reports and Critical/High/Medium smart contract bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required. In addition, all Critical/High/Medium bug reports must come with a suggestion for a fix in order to be considered for a reward. \n\nThe following known issues are considered to be out of scope of this bounty program: \n - All issues highlighted previously in the following audit report: \n - Peckshield Audit for DeFi SDK (August, 2020): [https://drive.google.com/file/d/158GG-J681xAc4d8pMibpP_SFJikX4HPM/view?usp=sharing](https://drive.google.com/file/d/158GG-J681xAc4d8pMibpP_SFJikX4HPM/view?usp=sharing)\n - Audit: [https://github.com/zeriontech/defi-sdk/blob/interactive/audits/Zerion%20DeFi%20SDK%20Trail%20of%20Bits%20Audit%20Report.pdf](https://github.com/zeriontech/defi-sdk/blob/interactive/audits/Zerion%20DeFi%20SDK%20Trail%20of%20Bits%20Audit%20Report.pdf)\n - External apps having integrations with Zerion\n\nRewards for critical smart contract 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 reward of __USD 10 000__ for Critical bug reports. \n\nCritical website and application bug reports will be rewarded with the full __USD 15 000__ only if the impact leads to a direct loss in funds or a manipulation of the votes or the voting result, as well as the modification of its display leading to a misrepresentation of the result or vote. All other impacts that would be classified as Critical would be rewarded no more than __USD 10 000__.\n\nZerion requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed is email address, full name, and country of residence.\n\nPayouts are handled by the __Zerion__ team directly and are denominated in USD. However, payouts are done in __USDC or DAI__.","outOfScopeAndRules":null,"assetsBodyV2":"Only those in the Assets in Scope table are considered as in-scope of the bug bounty program.","impactsBody":null,"immunefiStandard":true,"tags":{"general":["Immunefi Standard","KYC Required","PoC Required"],"productType":["Bridge","Crosschain Liquidity","DEX","Wallet"],"projectType":["Defi","NFT"],"ecosystem":["Arbitrum","Avalanche","BSC","ETH","Fantom","Optimism","Polygon","xDAI / Gnosis Chain"],"programType":["Smart Contract","Websites and Applications"],"language":["JavaScript","Solidity"],"featured":["Launched Recently"]},"legacy":{"technologies":["Smart Contract","Websites and Applications"],"blockchain_rewards":[],"smartcontract_rewards":[{"level":"Critical","payout":"Up to USD $25,000"},{"level":"High","payout":"USD $7,500"},{"level":"Medium","payout":"USD $1,000"}],"web_rewards":[{"level":"Critical","payout":"Up to USD $15,000"},{"level":"High","payout":"USD $7,500"},{"level":"Medium","payout":"USD $1,000"}]},"websiteUrl":null,"description":"At Zerion, we are on a mission to empower more people around the world with efficient, transparent, and censorship-resistant financial services.
