Railgun

Railgun is a smart contract system deployed on Ethereum, BNB Chain, Polygon, and Arbitrum that adds privacy to on-chain transactions and smart contract interactions, including decentralized exchange trading and lending. It uses zero-knowledge proofs, specifically zk-SNARKs, to shield wallet balances and activity from public view without routing funds through a separate blockchain or a cross-chain bridge. The system is aimed at users who want to trade, send tokens, or manage on-chain positions without exposing those actions on a public ledger.

Railgun operates as a set of smart contracts that sit on top of existing blockchains rather than running its own chain, which is why the block time in the data is recorded as zero and no consensus algorithm is listed. Users deposit assets into the contract system to build a shielded balance and can then interact with other protocols from inside that private balance without withdrawing first. The RAIL token is a governance and utility token; stakers receive a share of treasury rewards and gain the ability to vote on protocol updates.

The protocol collected 385,626 USD in fees over the trailing 30 days and 4,192,136 USD over the trailing 12 months, with fees and protocol revenue recorded as identical figures, reflecting a take rate of 100 percent for that period. Of that 30-day total, 222,261 USD was directed to token holders as holder revenue, while the supply-side revenue for the same period is recorded as zero, meaning liquidity providers or analogous participants received nothing directly. Fee growth over the last 30 days was negative 13.01 percent, indicating the pace of fee generation contracted relative to the prior period. Fees are paid by users who interact with the shielded smart contract system.
