RSK Infrastructure Framework wallet

What is Rootstock Infrastructure Framework (RIF)?

RIF belongs to Rootstock, a sidechain secured by Bitcoin miners through merged mining and running an EVM on top, so Solidity contracts settle in an environment anchored to Bitcoin. The token pays for and governs the infrastructure layer around that chain: RNS, which turns long addresses into readable names, the RootstockCollective where grants and proposals are decided, and USDRIF, the stablecoin issued in that ecosystem.

One detail catches people out. Rootstock does not use RIF for gas. Its fee coin is RBTC, bitcoin bridged onto the chain one to one, so a Rootstock wallet holding only RIF cannot move it until some RBTC is there too. That is the opposite arrangement from most chains where the headline token also pays the fees.

RIF also exists away from its home chain, as a token on Ethereum and on rollups and on Solana, so the same three letters can point at several distinct balances, each with its own fee coin. A transfer sent to the right-looking address on the wrong chain is simply a transfer on that other chain.

Tangem treats each of these as its own line with its own balance, and names the network a transaction is going out on before the card is tapped to sign it - the check is yours to make, and the app puts it in front of you. Holding RIF where every version of it is visible at once, instead of guessing which one you are looking at, is the sensible arrangement here.
