Alpen Is Bringing USDC to Bitcoin Finance—So Holders Can Borrow Without Selling

Bitcoin holders looking for dollar liquidity face a familiar choice: sell some $BTC or borrow against it. Alpen wants to make the second option part of a financial system built around Bitcoin.

The company announced that it plans to integrate Circle-issued $USDC and Circle’s Cross-Chain Transfer Protocol, or CCTP, when its mainnet launches later this year. $USDC would provide the dollar side of lending and trading markets built around native $BTC.

The proposition is straightforward: use Bitcoin as collateral to access dollars while retaining exposure to $BTC. Alpen says its architecture is designed to support those applications while keeping the underlying Bitcoin on Bitcoin.

Who Is Building Alpen?

Alpen Labs, the company building the platform, was founded in 2022 by four MIT alumni and is led by CEO Simanta Gautam. It develops Bitcoin infrastructure intended to support financial applications, including payments, lending and trading.

The company has disclosed $19.1 million across two funding rounds: a $10.6 million seed round and an $8.5 million strategic round announced in January 2025. Its backers include Ribbit Capital, Castle Island Ventures, DBA and Cyber Fund, giving it venture support as it works toward mainnet and commercial adoption.

Bitcoin Is the Collateral. $USDC Supplies the Dollars.

A lending market needs more than an asset people want to borrow against. It also needs liquidity to lend, a currency for pricing loans and a way to settle transactions.

$USDC is intended to fill that role on Alpen. Developers would be able to build applications where $BTC backs a loan and the borrower receives dollar-denominated liquidity, alongside trading markets that use $USDC for pricing and settlement.

“Bitcoin is the most important pool of digital capital, but much of the on-chain financial infrastructure around it still remains limited,” said Simanta Gautam, CEO and co-founder of Alpen Labs.

Alpen uses zero-knowledge verification and supports EVM-compatible applications—the development environment familiar to builders across Ethereum’s ecosystem. Its goal is to bring that application model to markets centered on $BTC, with wallets, custodians and financial platforms offering access through their own products.

CCTP Gives Dollar Liquidity a Route In

The second part of the announcement addresses how $USDC reaches those markets.

Circle’s CCTP supports native $USDC transfers by burning the tokens on one supported network and minting the corresponding amount on another. Alpen says that connection will be available alongside $USDC at mainnet launch.

Developers would be building around Circle-issued $USDC, with a route for dollar liquidity to move between Alpen and other supported networks.

“Bringing $USDC to Bitcoin through Alpen gives Bitcoin-native financial markets access to trusted dollar stablecoin infrastructure while keeping $BTC at the centre,” Gautam said.

That connection gives Alpen access to established stablecoin infrastructure. Whether it attracts enough liquidity to support competitive lending and trading is a separate question.

Bitcoin’s Next Chapter Is About Using It

Alpen’s announcement fits a broader shift in what companies are building around Bitcoin.

Earlier this week, Blockster covered GoBTC Pay’s working prototypes for AI agents paying merchants and each other in Bitcoin. The project is testing whether $BTC can become a payment method for software buying goods and services on a user’s behalf.

Alpen approaches Bitcoin’s utility from the borrowing side. GoBTC Pay explores how users and agents can spend $BTC; Alpen wants holders to access capital against it.

Both developments echo GoMining CEO Mark Zalan’s earlier feature about Bitcoin’s next chapter beyond holding. Their adoption will depend on whether these services offer enough convenience and value to justify their costs and risks.

Borrowing Without Selling Can Still End in a Sale

Retaining exposure to Bitcoin means retaining its downside too. If $BTC falls, borrowers may need to add collateral or repay part of their loan. Depending on the application’s rules, a sharp decline could trigger liquidation—turning a strategy designed to avoid selling into a forced sale.

The economics also depend on the $USDC available to lend. Thin liquidity could limit borrowing capacity or make loans expensive, while interest costs continue regardless of Bitcoin’s performance. Stablecoin availability alone does not guarantee attractive borrowing terms.

Keeping the underlying $BTC on Bitcoin also does not remove every technical dependency. Users would still need to assess Alpen’s verification system, the lending application’s smart contracts and collateral controls, and the infrastructure supporting cross-chain $USDC transfers.

Those tradeoffs will depend on how individual applications are built. The announcement does not yet detail borrowing limits, liquidation thresholds, withdrawal conditions or collateral-recovery procedures if an application fails.

Mainnet Will Put the Proposition to the Test

Alpen plans to launch its mainnet later this year, but the announcement does not specify an exact date or name the initial lending applications. The integration remains a planned capability rather than a live borrowing product.

The next milestone is a functioning market with lenders supplying $USDC, borrowers committing $BTC and clear rules for what happens when prices move against them. For holders, the deciding question will be how much dollar liquidity they can access—and how much control, cost and risk comes with it.
