Reserve Rights wallet

What is Reserve Rights (RSR)?

RSR belongs to the Reserve protocol, a system for creating stablecoins - called RTokens - that are backed by baskets of on-chain assets rather than by a bank account. RSR itself is not one of those stablecoins. It has two jobs: it votes on how each RToken is configured, and when staked onto a particular RToken it takes the first loss if something in that RToken's collateral basket defaults. Staking is per-RToken, not protocol-wide, and it is optional - plenty of RSR is simply held.

Supply is worth knowing about because it is unusual. The full 100 billion RSR was minted up front; nothing new is ever created. A large share sits locked in a contract that releases on a fixed schedule, so circulating supply increases over time without any new issuance.

Holding it across chains

RSR is an Ethereum ERC-20 by origin, and it is also deployed on Arbitrum and Base. These are distinct balances under one ticker. Since all three are EVM chains, one address serves all of them, which means a receiving address never reveals which network the person on the other end is checking - that is a question to ask, not to infer.

A governance token is the classic case of a key you barely touch and then suddenly need. Tangem generates that key inside the card and keeps it there, and a duplicate card held separately restores the same wallet if anything happens to the first; writing down a recovery phrase is a choice you can make rather than a step imposed on you. For RSR, which many people hold across years rather than weeks, that arrangement matches how the token is actually used. Supported networks in Tangem (3): Arbitrum One, Base, Ethereum.
