The RAILGUN project has developed this private DeFi system, which is user-friendly and operates independently of Layer 2 solutions or bridges, ensuring no compromises on security. RAILGUN serves as a privacy middleware available on Ethereum, Polygon, Arbitrum, and BNB Chain, allowing direct integration with applications and wallets. The primary interface for RAILGUN is Railway, an independent wallet enabling private transactions and anonymous swaps through 0x, a decentralized exchange (DEX) aggregator.Collect this post for FREE on Zora Network (only 100 mints available)Connect WalletCollectUniqueness of RAILGUNUnlike many competitors in the privacy space, RAILGUN operates on base layers like Ethereum and seamlessly integrates with external smart contracts, setting it apart. The project began gaining traction in July 2021, offering users native and hassle-free privacy solutions without relying on external privacy chains or basic mixers.Project HistoryRAILGUN emerged in July 2021 with open-source contributions and subsequently introduced the RAIL token via airdrop, establishing the RAILGUN DAO for governance. Notably, it launched the RAILGUN SDK on Ethereum and continued expanding to BNB Chain and Polygon. How RAILGUN FunctionsShielding AssetsUsers engage the RAILGUN Privacy System by "shielding" their assets. This non-custodial process involves sending assets (currently ERC-20 tokens or NFTs) to a public RAILGUN 0x address, which can then be shielded to a private 0zk address via RAILGUN's privacy pool, ensuring token anonymity.Transaction MechanicsRAILGUN transactions occur between 0zk addresses or within DeFi, involving encrypted data transmitted to Relayers via the private Waku network, ultimately interacting with the blockchain. Transactions use a UTXO model, employing ZK proofs for anonymity, while revealing only essential details like Relayer and destination addresses.For RAILGUN-to-RAILGUN (0zk) transactions, the sender, recipient, token type, and transacted amount remain totally private. The publicly visible details are the Relayer address and the destination address, i.e., the respective RAILGUN smart contract (for the given chain).For transactions involving other smart contracts (e.g., a DEX), the tokens/amount exchanged is also visible. Finally, users can unshield to any 0x address as they can with the typical coin mixer. In doing so, they can anonymously send tokens – linking the transaction to the RAILGUN smart contract address rather than their own.Integration and Additional FeaturesDevelopers use the RAILGUN SDK, employing Adapt Modules to bridge external contracts and the RAILGUN Privacy System. Noteworthy features include gasless transactions, multi-sends, and voluntary disclosure options for creating verifiable transaction histories.Governance and TokensRAILGUN operates with three governance tokens corresponding to specific deployments and DAOs on Ethereum, Polygon, and BNB Chain. Active Governors, staking RAIL tokens, influence governance and earn a share of DAO revenue.How to Use RAILGUN's Private DeFi System1. Create a WalletVisit RAILGUN's partner project, Railway's app, at https://app.railway.xyz to create a wallet.https://app.railway.xyzRailway: Private DeFi WalletRailway is a private DeFi wallet powered by the RAILGUN network. Shield, Send, and Swap across Ethereum, BNB Smart Chain, Polygon, and more.2. Two Addresses in Your WalletYour wallet will consist of two addresses:0x Address (Public)0zk Address (Private)Funds and activity in the 0zk address are hidden from public view such as on etherscan. We call funds in your 0zk address your private balance.3. Understanding Private BalanceFunds and activities in the 0zk address remain hidden from public view, such as on Etherscan. These funds are referred to as your private balance.4. Transferring FundsTransfer funds into your RAILGUN 0x address from any source (e.g., MetaMask or exchange wallet) across supported chains. Simply copy the 0x address generated in the first step and send funds to it as you would to any other address.5. Import Existing EVM WalletYou can import an existing EVM wallet by entering your seed phrase. Note: MetaMask will input only the first address if multiple addresses are linked to it.6. Privately Moving FundsTo move funds into your private balance, initiate the process by pressing the 'Shield' button. Choose the token and amount to shield. Your funds never leave the chosen chain.Input your password and click 'Shield'. The system generates a zk-SNARK proof, ensuring private ownership of your shielded assets.7. Additional FeaturesFor enthusiasts, any ERC20 token can be shielded by clicking the '+' icon above your balance and selecting 'Custom Token'.8. Private TransactionsOnce funds are in your private balance, you can privately send them to other 0zk addresses or unshield them back to any 0x public address. All fees are paid in stables/crypto of your choice, eliminating the need for ETH or $RAIL.RAILGUN SDK: Extending the CapabilitiesWith the RAILGUN SDK, you gain the ability to interact with any smart contract using your private balance. This means seamless swapping, trading, and earning on your favorite chain's dApps, ensuring complete privacy without compromising user experience or liquidity.Advantages of RAILGUN Over Other Privacy ProjectsBenefits for Users:Ease of Use: Simple and flexible asset support with NFT support coming soon.Maintained Liquidity: Users retain the same liquidity as before, without compromising on privacy or fracturing Total Value Locked (TVL) or user base.RAILGUN for DevelopersSimplified Integration: Integration into existing wallets or dApps is streamlined, requiring minimal adjustments to the codebase.Enhanced Security: RAILGUN's privacy system ensures security without the need for porting dApps to Layer 2 or introducing new security assumptions.Seamless Accessibility and SecurityRailway DEX, the first cross-contract integration of the RAILGUN SDK, enables token swapping within your private balance with low slippage, utilizing efficient order routing via the 0xProject API. The availability of Railway as a standalone desktop app, iOS, and Android ensures access to private DeFi from anywhere. Interested in learning more or joining the world of private DeFi?
