What is Railgun (RAIL)?

RAILGUN is a privacy system that runs as smart contracts directly on Ethereum, with no layer 2 and no bridge involved. Tokens are shielded into its contract, where zk-SNARK proofs let balances be held and moved without the amounts and counterparties being visible on chain, and unshielded back out when the holder wants them in the open again. RAIL is the governance and staking token of that system - it is not the privacy mechanism, and holding RAIL does not make your other tokens private.

This distinction is the one thing to be clear about before choosing a wallet. Plain RAIL sitting in an Ethereum address is an ordinary visible ERC-20 balance, transferred with ETH for gas like any other. A shielded RAIL balance inside RAILGUN is something else: it is held under the protocol's own keys derived from your wallet, and it will not show up as a token balance in a wallet app that is only reading the public chain state. If you shield tokens, the ability to see and spend them depends entirely on still controlling the wallet those viewing and spending keys were derived from.

That makes the key custody question sharper here than for most tokens. In Tangem the key is generated inside the card's secure element and does not leave it, and a spare card from the same set carries the same key so a lost card is not a lost balance - there is no phrase written down anywhere unless you decide you want one. When the asset in question sits behind keys derived from that one root, keeping the root in hardware you physically hold is the arrangement that makes sense.
