Earlier today, Coinbase announced the launch of “Bitcoin-Backed Loans” using Base, its native blockchain. But there’s one problem. (Actually, two.)

These loans are not backed by Bitcoin, nor are they even on the Bitcoin blockchain.

It’s disappointing that, in 2025, companies are still willingly omitting key details to mislead Bitcoin holders into giving up custody of their coins.

Here’s the truth: these loans are collateralized by cbBTC, Coinbase’s Bitcoin-wrapped product designed to compete with wBTC and tBTC. This is not Bitcoin. In fact, cbBTC is arguably the most centralized of these “wrapped” BTC tokens. To understand the trust assumptions associated with wrapped BTC, I recommend this excellent post by the Bitcoin Layers team: Analyzing tBTC Against wBTC and cbBTC.

Here’s the TL;DR:

“The BTC backing the cbBTC token is held in reserve wallets managed by Coinbase, a US-based centralized custodial provider. Coinbase holds funds backing cbBTC in cold storage wallets across a number of geographically distributed locations and additionally has insurance on funds they custody.”

Furthermore, instead of issuing these loans on a blockchain even remotely related to Bitcoin (such as Bitcoin sidechains or Bitcoin L2s), Coinbase is issuing them through Morpho Labs, a DeFi platform best described as an AAVE competitor. While Morpho is a well-established platform—and I don’t doubt its security—it has no connection to Bitcoin.

I, for one, look forward to seeing actual Bitcoin-backed loans issued on the Bitcoin network itself. Many L2 teams are working hard to make this a reality, striving to minimize trust assumptions—or even eliminate the need for bridging altogether (bullish!).

Why do we need native Bitcoin-backed loans in the first place? Consider this: many Bitcoiners today face stringent tax regulations that impose hefty liabilities on long-term holders who sell their Bitcoin to fund significant purchases like a house or a car. Taking out a loan backed by BTC allows individuals to avoid triggering these tax events.

Moreover, most Bitcoiners are confident that Bitcoin’s price will be significantly higher in the future than it is today. So why would anyone sell an asset with such promising long-term potential? Bitcoin-backed loans enable holders to retain exposure to Bitcoin’s upside while accessing the liquidity needed to meet life’s financial demands.

In today’s market, the options for Bitcoin-backed lending are limited. You can either rely on centralized companies (like the reputable team at Unchained) or turn to “DeFi” protocols, which are often centralized themselves and, in some cases, riskier than centralized alternatives like Unchained. However, there is currently no truly Bitcoin-native solution—no option for Bitcoiners to maintain custody of their coins while accessing loans.

Some companies, like Lava.xyz, are beginning to address this gap. However, their market share remains a small fraction of the volumes handled by existing DeFi platforms. (Keep an eye on Lava—they’re poised to make waves in 2025!)

One quote from the original announcement stood out to me:

“The integration of Bitcoin-backed loans on Coinbase is ‘TradFi in the front, DeFi in the back,’” said Max Branzburg, Coinbase’s vice president of product, in a statement to The Block.

Let’s call it what it really is: centralized in the front, and centralized in the back.

It’s time to leave these misleading offerings behind and bring true Bitcoin Finance (BTCfi) to users—not just marketing buzzwords and half-truths.

Instead of saying: Bitcoin backed on-chain loans let’s say: multisig-backed derivatives loans on a centralized chain.
