Dollar on Chain (DOC)

Q: Is DOC safe?

As of Oct 24, 2026, Pharos grades DOC B- (68/100) on its Safety Score. Pharos's reviews record that admin controls such as a pause or an upgradeable contract exist, though no power to freeze a specific holder was found, and any holder can use its reviewed redemption route. That grade is in the Score's upper band, which does not rule out losses. The grade moves as reserve, redemption, peg and control evidence changes; the live Safety Score on this page shows the current reading.

Q: What backs DOC?

Pharos records DOC's reserves as of Sep 26, 2026 as 100% Rootstock BTC (rBTC) collateral. Reserve evidence: live reserve feed configured. Pharos classifies the backing as Crypto-Collateralized.

Q: Can DOC be frozen or blacklisted?

Based on tracked contract metadata and blacklist coverage, admin controls such as a global pause or an upgradeable contract are recorded, but the review found no active power to freeze or seize a specific holder's balance on material deployments.

Q: How do you redeem DOC?

Under the route Pharos reviewed on Aug 12, 2026, any holder can redeem DOC for BTC. Redemption settles atomically on-chain. The fee is variable or not fully published. Whether a given holder qualifies is set by the route's own terms, not by this summary.

Rootstock CDP With an rBTC Exit

DOC is Money On Chain's dollar on Rootstock, minted against rBTC held in the protocol's own contracts rather than bank deposits or a fiat . Mechanically it is a system with : DOC holds the senior claim on pooled rBTC, while BPRO holders absorb the residual Bitcoin exposure. Holders exit through permissionless for rBTC, which keeps the exit pillar the strongest of the three. That conversion runs on the OMoC BTC/USD oracle, and an April 2026 consensus-bypass flaw in that feed prompted a protocol panic pause before the protocol reported a fix. The B- overall grade is held back most by economic control: an accepted Money On Chain governance proposal can change collateral parameters or upgrade mint-critical logic. The Arbitrum and Ethereum deployments are external lock-and-mint representations rather than additional collateral. The durable constraint is that every DOC rests on one Bitcoin sidechain, one price feed and one governance system.

Review notes & sources (17)

DOC is minted permissionlessly against rBTC locked in Money On Chain's overcollateralized contracts on Rootstock, with permissionless DOC-for-rBTC redemption. The DoCToken is Ownable and its owner is the MoCExchange proxy, which is the only direct minter. MoCExchange is a zeppelinOS transparent proxy whose admin is the published Admin contract, owned by the Upgrade Delegator, which is governed by the Money On Chain Governor. The Governor authorizes Changer contracts and can therefore upgrade mint-critical logic, so the mint bound is governance-revocable rather than immutable. The Governor's owner is the verified Money On Chain VotingMachine proxy: token holders vote on proposals, and an accepted proposal calls the Governor to execute its Changer. The VotingMachine is itself upgradeable through a ProxyAdmin and UpgradeDelegator governed by that same Governor. The posture remains partially bounded because governance can alter collateral parameters and replace mint-critical logic, not because of an unidentified off-chain signer set.

Control posture

Material control is classified as exercised through an onchain governance process rather than one operator or signer group.

Decentralized (DeFi) is the broader governance classification. Control posture describes more precisely where operational authority sits.

Control posture is not a Safety Score input. Economic Control is scored from the reviewed mint authority, oracle and bridge evidence.

Money On Chain's pooled rBTC system consumes the OMoC BTC/USD feed, where up to ten staked operators use off-chain quorum signatures and elected fallback publishers. An April 2026 consensus-bypass flaw prompted a protocol panic pause; the protocol's incident report states the bug was fixed.

DOC is natively a Rootstock rBTC-collateralized CDP stablecoin. Its Arbitrum deployment (0x2ad62eb9...) is a self-deployed LayerZero V2 OFT representation documented by Money On Chain. Its low-supply Ethereum deployment is the legacy RSK Token Bridge eDOC SideToken (0x69f6d4d4...): at Ethereum block 25580192, the verified Bridge mapped original Rootstock token 0xe700691d... to eDOC in both directions. eDOC's sole minter was that Bridge proxy; upgrades and bridge ownership terminated at a 2-of-3 MultiSigWallet, while mint claims required the bridge's 2-of-5 Federation. Both peripheral deployments are external lock/mint routes rather than canonical rollup bridges.

DOC

Possible

An admin control could restrict holders, but the review found no active power to freeze or seize a specific holder's balance on its material deployments. Typical cases are a global transfer pause, an upgradeable token contract, or a blacklist role that exists but is unassigned.

Review notes & sources (13)

The deployed MoCExchange is a verified proxy implementation, but the current whitelist set/controller state was not independently enumerated. The upstream arbitrary-account methods are therefore evidence of a candidate route, not confirmation that a currently whitelisted member can reach it in this deployment. The known MoC wrapper passes msg.sender (MoC.sol lines 316 and 335). Token/exchange proxy control makes Possible under the binding policy; whether a current whitelisted operator has an arbitrary-holder path remains unresolved.
