R-Assets are Router Protocol's wrapped assets that function as a representation token or a proof, akin to an LP token. These assets maintain 1:1 mapping with their underlying assets since one "R-Asset" can only be minted if one "Asset" is locked. Let us consider USDC and RUSDC. Router can only mint a RUSDC when it has a USDC successfully locked in its reserve. This means that the number of RUSDC in circulation is always equal to the number of USDC locked in Router's bridge reserves.
