TL;DR Help test Wanchain’s Cardano Bridge and earn up to 10,000 $ADA and $WAN.Welcome to the <a href="https://bridge-dev.wanchain.org/" rel="noopener noreferrer nofollow">Cardano Bridge</a> Public Bug Bounty! As a valued member of the Wanchain and Cardano communities, your role in ensuring the security and stability of the <a href="https://bridge-dev.wanchain.org/" rel="noopener noreferrer nofollow">Cardano Bridge</a> is crucial. Your expertise in uncovering bugs and areas for improvement is invaluable for these cutting-edge blockchain interoperability solutions. The Wanchain team is committed to user safety and security above all else. This Public Bug Bounty is a vital part of this effort. Your findings will be rewarded as we work together to make blockchains interoperable. Thank you for your help!<h3 id="background">Background</h3>Wanchain is a sustainable Layer 1 PoS blockchain and a decentralised wide area network of blockchains. The Wanchain Layer 1 PoS blockchain is a full Ethereum-like environment that works with industry-standard Ethereum tools, DAPPs, and protocols. Wanchain’s wide area network of blockchains is a decentralised system of direct, non-custodial cross-chain bridges that connect both EVM and non-EVM networks without requiring any centralised intermediaries. Currently, more than 20 Layer 1 and Layer 2 networks are connected by Wanchain’s wide area network of blockchains including but not limited to Bitcoin, Ethereum, Arbitrum, Avalanche C-Chain, BNB Chain, Fantom, Litecoin, OKC Network, Optimism, Polkadot Relay Chain, Polygon, and the XRP Ledger.Last July, the team at <a href="https://iohk.io/en/blog/posts/2022/07/08/bridges-and-sidechains-wanchain-making-cardano-interoperable/" rel="noopener noreferrer nofollow">Wanchain shared details about their ongoing work with IOG and MLabs</a> to make Cardano interoperable — a complex undertaking since Cardano is a heterogeneous, non-EVM network. The goal was to build the infrastructure required to enable applications spanning multiple blockchains, thereby driving the adoption of Cardano’s ecosystem, promoting Wanchain’s network-agnostic cross-chain infrastructure, and advancing the future of Web3.In late March, <a href="https://www.essentialcardano.io/article/update-cardano-cross-chain-bridges-and-other-interoperability-solutions" rel="noopener noreferrer nofollow">Wanchain announced that decentralised, non-custodial, bi-directional cross-chain bridges were officially up and running on Cardano Pre-Production</a>! The following decentralised, non-custodial, bi-directional cross-chain bridge types are currently deployed:<ol><li>Move ADA to any EVM-compatible chain and back</li><li>Move Cardano native tokens to any EVM-compatible chain and back</li><li>Move any coin or ERC20 token from any EVM-compatible chain to Cardano and back</li></ol>Now, after hitting this significant development milestone, Wanchain is launching a Public Bug Bounty to encourage and incentivise the discovery and reporting of bugs and security vulnerabilities in the bridges’ front-end, smart contracts, wallet interactions, blockchain explorer and any other bridge-related element not explicitly mentioned here. The aim of this Public Bug Bounty is for users, developers and security researchers to identify any issues before the mainnet launch, thereby improving the overall security and integrity of the <a href="https://bridge-dev.wanchain.org/" rel="noopener noreferrer nofollow">Cardano Bridge</a>.<h3 id="key-information">Key information</h3><ul><li>Bounty Period: April 18th, 2023 to May 8th, 2023 [<a href="https://twitter.com/wanchain_org/status/1655496699568173057" rel="noopener noreferrer nofollow">EXTENDED to May 29th</a>]</li><li>Rewards: 10–10,000 $ADA &amp; 10–10,000 $WAN, depending on severity</li><li>Pre-Production Bridge: <a href="https://bridge-dev.wanchain.org/" rel="noopener noreferrer nofollow">https://bridge-dev.wanchain.org/</a></li><li>$WAN Testnet Faucet 1: <a href="https://t.me/wan_testnet_faucet_bot" rel="noopener noreferrer nofollow">https://t.me/wan_testnet_faucet_bot</a></li><li>$WAN Testnet Faucet 2: <a href="https://wanchain-faucet.vercel.app/" rel="noopener noreferrer nofollow">https://wanchain-faucet.vercel.app/</a></li><li>$ADA Pre-Production Testnet Faucet: <a href="https://docs.cardano.org/cardano-testnet/tools/faucet" rel="noopener noreferrer nofollow">https://docs.cardano.org/cardano-testnet/tools/faucet</a></li><li>$DJED Pre-Production Environment: <a href="https://preprod.djed.xyz/djed" rel="noopener noreferrer nofollow">https://preprod.djed.xyz/djed</a></li><li>Goerli $ETH faucet: <a href="https://goerlifaucet.com/" rel="noopener noreferrer nofollow">https://goerlifaucet.com/</a></li><li>Testnet WanScan: <a href="https://testnet.wanscan.org/" rel="noopener noreferrer nofollow">https://testnet.wanscan.org/</a></li><li>Testnet Token Addresses: <a href="https://testnet.wanscan.org/tokens" rel="noopener noreferrer nofollow">https://testnet.wanscan.org/tokens</a></li><li>Nami Wallet: <a href="https://namiwallet.io/" rel="noopener noreferrer nofollow">https://namiwallet.io/</a></li><li>MetaMask Wallet: <a href="https://metamask.io/" rel="noopener noreferrer nofollow">https://metamask.io/</a></li><li>Cardano Bridge on Github: <a href="https://github.com/wanchain/cardano-crosschain-contracts" rel="noopener noreferrer nofollow">https://github.com/wanchain/cardano-crosschain-contracts</a></li><li>Bug Bounty Report Form: <a href="https://forms.office.com/r/F9b9RrzS04" rel="noopener noreferrer nofollow">https://forms.office.com/r/F9b9RrzS04</a></li></ul><h3 id="public-bug-bounty-rewards">Public Bug Bounty rewards</h3>Rewards for submitting verified bugs and suggested improvements range from 10 $ADA &amp; 10 $WAN to 10,000 $ADA &amp; 10,000 $WAN, depending on severity.<ul><li>Trivial: 10 $ADA &amp; 10 $WAN</li><li>General: 50 $ADA &amp; 50 $WAN</li><li>Major: 200 $ADA &amp; 200 $WAN</li><li>Critical: 1500 $ADA &amp; 1500 $WAN</li><li>Fatal: 10,000 $ADA &amp; 10,000 $WAN</li></ul>Additionally, participants who participate in this Public Bug Bounty may become eligible for extra rewards.Please submit all bugs and suggestions using the <a href="https://forms.office.com/r/F9b9RrzS04" rel="noopener noreferrer nofollow">Bug Bounty Report Form</a>.<blockquote>Note: Where multiple users submit the same bug, only the first user to submit the bug via the Bug Bounty Report Form will receive the reward.
