Shielding

How to shield tokens into a RAILGUN Wallet

Shield transactions are executed publicly, using a public wallet.

Under the hood, the shield action sends ERC-20 tokens into the RAILGUN contract, where they are associated with a RAILGUN Wallet and a private balance. Once shielded, the owning RAILGUN Wallet can initiate private transfers and cross-contract calls to interact with external smart contracts.

Shielding actions incur a 0.25% fee on the amount of tokens shielded. This fee rate is subject to change by RAILGUN DAO. After tokens are shielded, private transfers incur no fees.

NOTE: Do not shield rebase tokens into RAILGUN, as these are not supported. For a list of rebase tokens, see Rebase Token List (Coingecko).
