BTCcx Adds $100 Million in Bitcoin-Linked Collateral to Dolomite
In the Oct. 19 snapshot reviewed for this article, Dolomite’s Ethereum market dashboard showed $100.08 million in BTCcx supplied, broadly matching the $100 million announcement by Dolomite and Concrete. Etherscan’s holder records separately showed about 1,221.15 BTCcx held by Dolomite’s margin contract. The two figures document the token position and collateral supplied, not the amount borrowed.
Supplied Collateral Is Not the Outstanding Debt
Under the documented structure, BTCcx itself is never borrowable. Concrete issues BTCcx on Ethereum as a representation of custodied Bitcoin, supplies the tokens to Dolomite and manages the borrowing position. Concrete borrows against the BTCcx collateral, rather than market participants borrowing BTCcx directly. Dolomite’s announcement did not specify the outstanding debt secured by BTCcx, meaning the reported $100.08 million in supplied assets should not be treated as a $100.08 million borrowing figure.
How Concrete Manages the BTCcx Borrowing Position
Dolomite says the borrowed funds are generally deployed into yield-bearing strategies that can be unwound for repayment. If collateral prices fall beyond acceptable thresholds, Concrete is responsible for making partial repayments to restore the position’s health.
According to Dolomite, the assets use the Chainlink price feed for their respective underlying assets. The BTCcx arrangement combines BitGo’s custody of Bitcoin with Concrete’s issuance and management of the borrowing position and Dolomite’s market for the supplied tokens. Market prices can change while a custody redemption is pending, creating a timing dependency between valuation and settlement.
Forced Liquidation Requires a Multi-Step Settlement Process
If a forced liquidation becomes necessary, a temporary, market-specific claim token represents the collateral during settlement. The underlying asset goes through off-chain redemption, the proceeds return on-chain to repay the debt and the temporary claim token is closed. Dolomite’s documentation still labels the settlement contracts “Coming soon.”
BTCcx Builds on an Existing Dolomite-Concrete Arrangement
BTCcx extends the existing arrangement between Dolomite and Concrete. Dolomite already supports Concrete’s WLFIcx, another BitGo-custodied asset issued on Ethereum. In the same Oct. 19 market snapshot, Dolomite’s dashboard showed $108.65 million in WLFIcx supplied.
The figures place BTCcx alongside a Concrete asset already supported on Dolomite’s Ethereum market. They also illustrate the difference between the value of collateral supplied to the market and the debt raised against that collateral, a distinction that is not visible from the dashboard totals alone.
Why This Matters
The BTCcx structure demonstrates how a tokenized representation of Bitcoin can support borrowing without becoming directly borrowable itself. Its operation depends on several connected components: BitGo’s custody, Concrete’s issuance and position management, Chainlink-based pricing and the on-chain market maintained by Dolomite. The structure also allows market prices to move while an off-chain redemption is being completed.
That makes the separation between collateral and debt central to understanding the announcement. The $100.08 million supplied figure and the approximately 1,221.15 BTCcx recorded in Dolomite’s margin contract show the scale of the collateral position, but they do not reveal the outstanding loan amount. Forced liquidation would also require both an off-chain custody process and an on-chain repayment process before the temporary claim token could be closed.
Frequently Asked Questions
What is BTCcx, and who borrows against it?
BTCcx is issued by Concrete on Ethereum as a representation of Bitcoin custodied by BitGo. Concrete supplies BTCcx to Dolomite and manages the borrowing position. The token itself is not borrowable; Concrete borrows against it.
How much did Concrete borrow against BTCcx?
The outstanding debt was not disclosed. Dolomite’s announcement did not specify the debt secured by BTCcx. The dashboard’s $100.08 million in supplied BTCcx and Etherscan’s record of approximately 1,221.15 BTCcx reflect collateral and holdings, not the amount borrowed.
How would a forced liquidation be settled?
A temporary, market-specific claim token would represent the collateral while the underlying asset underwent off-chain redemption. The proceeds would then return on-chain to repay the debt before the temporary token was closed. Dolomite’s documentation still labels the settlement contracts “Coming soon.”
