Core Architecture
Liberty SHIELD is a unified privacy and routing layer designed for dApps across any blockchain to integrate and use.
LibertySwap is one of the applications that leverages Liberty Shield to facilitate private swaps. See Liberty Shield vs Liberty Swap
Liberty SHIELD enables users to move assets into and out of Railgun and other privacy protocols seamlessly, while preserving strong privacy guarantees and reducing cross-chain complexity.
Liberty Shield abstracts away gas management, relayers, and liquidity fragmentation, allowing users to focus on outcomes rather than infrastructure.
Functionality
At launch, Liberty Shield supports the following flows on
Shield ETH: Convert public ETH on Ethereum into a private Railgun balance instantly.
Unshield ETH: Convert ETH held in a Railgun balance back into public ETH on Ethereum instantly.
These operations are executed directly from the Railgun system and do not rely on external liquidity pools.
In the future state:
Users can shield multiple assets, such as ETH and stablecoins, from many source blockchains into Railgun and other supported privacy protocols and layers.
From a shielded balance, for example a Railgun balance, users can unshield assets to any supported destination chain.
The destination chain does not need native Railgun or other privacy protocol or layer support.
Liberty Shield becomes the universal entry and exit point for leading privacy protocols and layers.
How Shielding Works
Users start with assets on a public blockchain.
Liberty Shield routes the assets into Railgun or other privacy contracts.
Funds appear as shielded balances inside Railgun or other privacy contract balances.
Public transaction history is broken, and assets gain strong privacy guarantees.
From this point forward, all actions originate from shielded balances.
How Unshielding Works
Users choose a destination chain and asset.
Liberty Shield routes funds out of Railgun or other privacy contract balances
Assets are delivered directly to the destination chain.
The user receives funds without revealing source history.
This works even if the destination chain does not natively support Railgun.
Fees and Execution Model
Liberty Shield uses a simple fixed fee model:
0.5% total fee, covering:
Blockchain gas fees
Railgun fees
Relayer fees
Cross chain execution costs
Gasless for users
Instant execution
No liquidity constraints
There are no variable fees, no gas estimation issues, and no need to manage multiple tokens for gas.
