Different by design

BITCOIN PRINCIPLES. DOLLAR STABILITY.

DOC is designed to maintain a 1:1 parity with the US dollar. Its backing stays in bitcoin, held in smart contracts on Rootstock.

bitcoin, not bank reserves.

DOC is collateralized in rBTC, bitcoin on Rootstock. It does not depend on dollar deposits or fiat reserves.

Your wallet. Your control.

Mint and redeem through smart contracts. No custodial account or centralized intermediary is required by the protocol.

Part of the Bitcoin ecosystem.

Use DOC with wallets, applications, and protocols on Rootstock, a Bitcoin sidechain with smart contract capabilities.

A DIFFERENT FOUNDATION.

What changes when bitcoin and smart contracts replace fiat reserves and bank custody?

Feature	DOC	Fiat-backed stablecoin model
Backing	bitcoin (rBTC)	Fiat reserves and related assets
Collateral custody	Smart contracts on Rootstock	Banks and other custodians
Issuance and redemption	Through the protocol	Depends on the issuer
Transparency	On-chain collateral	Depends on reserve disclosures

The comparison describes different models. Specific stablecoins vary; this is not a claim that all alternatives work the same way.

Mint. Hold. Redeem.

THE LOOP IS INFINITE.

Move between bitcoin and dollar stability without asking a centralized issuer for permission.

BPRO holders provide the collateral and absorb bitcoin’s volatility. This risk-sharing model makes DOC issuance possible without requiring DOC users to manage their own collateral position.

He can mint DOC with rBTC from his own wallet, without going through an exchange. When he wants bitcoin exposure again, he can redeem through the DApp.

A few things to know

YOUR QUESTIONS. STRAIGHT ANSWERS.

Is DOC really backed by bitcoin?

Yes. DOC is backed by rBTC held in smart contracts on Rootstock. Its backing does not rely on banks or dollar reserves.

How does it work without fiat reserves?

DOC uses bitcoin collateral and the protocol’s risk-sharing mechanism to target dollar stability. BPRO holders supply the collateral that supports DOC issuance.

What happens if bitcoin’s price falls?

Money On Chain is designed with a Non-Liquidation feature and incentives to maintain stability through market movements. That design is not a promise that holding DOC is risk-free; review the protocol documentation to understand the mechanism.

How can I convert DOC back to bitcoin?

You can redeem DOC for rBTC through the DApp or swap it on supported markets. Check the current protocol conditions, available liquidity, and transaction fees before proceeding.

Is DOC issued without fiat?

Yes. Issuance uses rBTC, and BPRO collateral is also provided in rBTC. USD is the reference unit for the peg, not the asset held as backing.
