Railgun (RAIL) is a smart contract–based privacy system designed to bring confidential transactions and interactions to decentralized finance (DeFi). Built directly on the Ethereum mainnet, Railgun uses Zero-Knowledge Proof (ZK-SNARK) technology to shield user addresses, ensuring transactional privacy without reliance on centralized intermediaries or layer-2 dependencies.

In an ecosystem where transparency is the default, Railgun offers a unique value proposition: on-chain privacy combined with trustless architecture. Below is a detailed look at how the protocol works, what sets it apart, and how the RAIL token powers its governance model.

What Is Railgun?

Railgun is a privacy-preserving smart contract system that allows users to conduct DeFi activities—such as trading, leveraging, liquidity provision, and payments—without revealing wallet addresses or on-chain behavior. Its infrastructure uses ZK-SNARKs to verify transactions without exposing personal identifiers.

Because Railgun operates directly on Ethereum rather than using a specialized sidechain or rollup, it avoids the security assumptions and trust models required by many privacy or scaling solutions. Users maintain full control over their assets in a familiar environment compatible with wallets like MetaMask.

Supported Assets

Railgun initially supports several ERC-20 assets, including:

• RAIL
• USDC
• renBTC
• renZEC
• Additional tokens subject to governance approval

Security and Ease of Use

Security is central to the Railgun architecture. The development team includes experts in cryptography, blockchain engineering, and smart contract security. Railgun has undergone audits from respected firms such as ABDK, and its codebase uses well-established libraries to minimize attack vectors.

The user experience is designed to feel familiar. Anyone who has used MetaMask or similar Web3 wallets will find Railgun intuitive. All ZK-SNARK operations occur in the background, enabling private sends, swaps, or liquidity operations without additional technical steps.

Railgun’s design is both trusted—via reputable audits and experienced contributors—and trustless, since its smart contracts are open source and verifiable by the public.

Key Use Cases

Railgun enables private, permissionless financial activity across DeFi. Common use cases include:

• Entering new token positions without exposing trading intent
• Building a shielded balance to hide portfolio composition
• Preventing third-party tracking, data surveillance, and wallet profiling
• Executing “darkpool-style” trading without revealing strategies to bots or copy traders
• Making confidential payments—for example, legal consultations or professional services
• Receiving donations without exposing donor history
• Avoiding targeted advertising or exploitation based on on-chain behavior
• Maintaining personal privacy from acquaintances or the public

Where to Buy RAIL

The RAIL token is available on major decentralized exchanges, including:

• SushiSwap
• Uniswap
• Balancer

Users can explore relevant liquidity pools on these platforms to acquire RAIL with a variety of trading pairs.

RAIL Token: Governance and Utility

RAIL is the native governance token of the Railgun ecosystem. Token holders can participate in protocol upgrades, parameter changes, and treasury decisions. Staking RAIL grants voting power, enabling the community to shape the project’s future development.

One of Railgun’s innovations is privacy-preserving governance. RAIL holders can vote anonymously using the same shielding technology that powers the protocol, preventing coercion, influence tracking, or wallet-based discrimination.

Developers of Railgun hold no overriding privileges; all meaningful changes must be approved by RAIL token holders, maintaining the platform’s decentralized ethos.

Tokenomics

Supply Overview

• Circulating supply at launch: 50 million RAIL
• Maximum supply: 100 million RAIL

Initial Distribution

• 25% Airdrop
  Distributed to Ethereum addresses that have historically donated to privacy nonprofits such as the TOR Project, Free Software Foundation, and the Right to Privacy Foundation.
• 25% Foundation
  Managed by the Right to Privacy Foundation, a registered nonprofit. These tokens support long-term development, grants, and platform growth.
• 50% DAO
  Allocated to the DAO as locked, unminted tokens. These can only be activated through governance votes—for example, to boost liquidity mining rewards.

Railgun emphasizes decentralization. There is no corporate entity, no VC allocation, and no equity holders—ensuring that governance remains entirely community-driven.

Why Railgun Matters

As regulatory scrutiny increases and blockchain analysis grows more sophisticated, on-chain privacy is becoming essential rather than optional. Railgun offers a principled, transparent, and decentralized approach to financial privacy—aligning with the ethos of open and permissionless blockchain infrastructure.
