BTCS Sells Ether Below Cost to Manage Aave Collateral

Nick Sawinyh on 13 Nov 2026

BTCS disclosed that it sold ether below its purchase cost to manage collateral and repay DeFi borrowings. Its quarterly filing reports $64.1 million owed on Aave as of November 9, 2026, including accrued interest, backed by 46,676 ETH valued at $99.3 million.

The company reported no full or partial liquidation of its DeFi borrowings through November 11. BTCS described the sales as its own collateral management. The filing accounts separately for losses from selling ether and losses recognized when depositing ether into liquidity pools. Neither category is evidence that Aave liquidated the company.

BTCS said the sales “were executed at prices below their original cost basis as part of the Company’s active management of collateral levels and health factors associated with DeFi borrowing arrangements.” The company realized those losses while pursuing a borrowing strategy that uses ether as collateral for debt owed in stablecoins.

The collateral snapshot

BTCS used an ether closing price of $2,127 to value its November collateral. That price belongs to the filing’s dated snapshot; it is not a current valuation of the position. The company said a decline in ether could require it to add collateral or repay debt. Management monitors collateral values and loan health factors on an ongoing basis.

At September 30, BTCS reported approximately 46,607 Aave receipt tokens representing wrapped ether, with a fair value of $125,097,651. Those assets remained recorded as ether on its balance sheet, measured using quoted prices in active markets. The November snapshot reports a similar quantity of underlying ether at a lower dollar valuation than the prior quarter-end holdings.

Aave’s liquidation documentation identifies collateral additions and debt repayments as ways to improve a position’s health factor. A position becomes eligible for liquidation when its health factor falls below 1. Any network participant can liquidate an eligible position by repaying debt on the borrower’s behalf and receiving collateral plus a liquidation bonus.

BTCS’s board permits borrowing at a maximum loan-to-value ratio of 50% at the time the loan is taken. It also permits temporary operational exceedances lasting no more than two days. The board’s limit applies when the company takes out a loan. Aave’s rules determine whether the position can be liquidated as the value of its collateral and the amount of its debt change.

The loans have no fixed maturity, according to the filing. They remain outstanding until repayment or liquidation under Aave’s terms. BTCS also warns that it has no recourse against the protocol or a counterparty for liquidation, technical failure, smart-contract vulnerabilities or oracle manipulation. Its collateral-management disclosure is separate from Aave’s earlier market freezes following the Binance breach.

Stablecoin debt finances liquidity positions

BTCS primarily owes $USDT and $GHO. It must return the borrowed stablecoin units plus protocol interest, rather than an equivalent quantity of ether. The company says it primarily uses the borrowings to fund revenue-generating liquidity-pool positions. It evaluates the cost of that borrowing against the gross profit produced by the capital it deploys.

From January 1, 2025 through November 11, 2026, BTCS reported approximately $152.4 million of cumulative stablecoin borrowing and $89.4 million of repayments through Aave. Those totals include on-chain debt refinancing. They measure borrowing and repayment activity over the period, not the debt still outstanding. The filing reports the outstanding position separately in its November snapshot.

On November 9, the reported annual borrowing rates were approximately 6.54% for $USDT and 4.5% for $GHO. BTCS reported a weighted-average annualized rate of 3.94% across its DeFi borrowing during the nine months ended September 30. The earlier average covers a period and a mix of debt, while the November rates apply to individual borrowed assets on a particular date.

The ether supplied as collateral also earns variable interest, according to BTCS. Protocol conditions affect both the income on that ether and the cost of the stablecoin debt. Returns from liquidity positions depend on activity and market conditions. BTCS says it cannot control Aave’s rate adjustments and remains exposed to significant increases in borrowing costs.

Depositing ether into a liquidity pool also has an accounting consequence. BTCS says it derecognizes the underlying ether and recognizes a pool position. When the ether’s fair value at deposit is below its carrying value, the exchange produces a realized loss. The company attributed increased realized losses over the reporting period both to those deposits and to ether sales for collateral management and debt repayment. It also reported a net realized gain for the quarter, primarily from exiting liquidity-pool positions.

Cash and collateral have different constraints

BTCS held approximately $463,000 in cash at September 30, compared with $1,526,000 at the end of the prior year. At quarter-end, a significant majority of its digital assets measured at fair value were deployed as Aave collateral. Protocol-enforced restrictions made those assets unavailable for general corporate purposes while the related borrowing remained outstanding, according to the filing.

The company’s broader November 9 liquidity figure was $142.6 million. That included cash, stablecoins and liquid digital assets, primarily ether. BTCS cautioned that the aggregate includes volatile digital assets and DeFi balances that can change materially over short periods. The collateral restrictions still apply to the assets pledged against borrowing, so the aggregate is not a cash balance available to repay lenders.

Total debt at that date was approximately $82.0 million, including the Aave borrowing and $17.9 million of convertible notes. The notes fall due within 12 months of the filing. Management nevertheless assessed its resources, access to capital markets and ability to manage DeFi borrowing as sufficient for at least the next twelve months, subject to market conditions and its operating plans.

The filing also warns that protocol withdrawal periods, network congestion and market volatility can restrict conversion of assets into cash. It reports a November 9 collateral position and no liquidation through November 11, but gives no live health factor for the position today.
