This is meant to avoid rebasing while still passing carrying costs on-chain.\n\nWhat is actually new is the explicit pairing of per-token decay with a balance-preserving reconciliation rule; most prior RWA work either absorbs costs off-chain or accepts rebasing. The authors correctly note that rebasing breaks ERC-20 composability with existing DeFi contracts, and they frame the standard as asset-agnostic.\n\nThe soft spot is that the reconciliation mechanism itself is never described. There is no update rule for totalSupply, no invariant relating q(t) to balances, and no argument that the step can be performed without external calls, timing windows, or oracle risk. The claim that ERC-20 semantics and DeFi integrations remain intact therefore rests on an unshown construction. No code, pseudocode, formal model, or even a worked numerical example appears.\n\nThis is aimed at people building RWA token standards who are already thinking about negative carry. A reader looking for a concrete, implementable design or a formal argument will find the paper too thin. It does not rise to the level that would justify sending it to referees; the central technical claim needs the missing reconciliation rule spelled out before any serious review makes sense.","headline":"A high-level design sketch for encoding carrying costs in RWAs that asserts a reconciliation fix but supplies no mechanism, equations, or verification.","tokens_in":2411,"tokens_out":363,"would_cite":false,"duration_ms":17100,"reading_group":"no","serious_thinker":"unclear","would_accept_peer_review":false},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"grok-4.3","headline":"The Fungible Reserve Standard encodes carrying costs into asset-backed tokens using a decreasing asset-per-token variable and supply reconciliation.","keywords":["Fungible Reserve Standard","carrying costs","asset-backed tokens","tokenization","ERC-20 composability","supply reconciliation","real-world assets","DeFi"],"falsifier":"Deploy an FRS token on a public testnet, apply a known carrying cost rate over several periods, and check whether holder token counts stay constant while total supply decreases and standard DeFi contracts continue to accept the token without modification.","tokens_in":2662,"feed_emoji":"","tokens_out":778,"duration_ms":35097,"temperature":0.7,"pith_summary":"The paper proposes the Fungible Reserve Standard to move the custody, insurance, and audit costs of physical assets like metals or commodities into the token itself on a blockchain.
