You can borrow against Bitcoin, stake it, trade it on-chain, post it as margin for perpetuals, supply it to a liquidity pool, convert it into stablecoins to pay someone, and use it to buy tokenised stocks. Two of those are worth doing for most holders, two are worth doing for a specific kind of trader, and three are worth skipping unless you have a reason. None of them happen on Bitcoin’s own chain, so every one of them starts with moving value somewhere else.

Why would anyone want Bitcoin in DeFi?

Bitcoin holds more value than anything else in crypto and does less with it than almost anything else in crypto. At roughly $78,482 per coin on 8 September 2026, its market capitalisation sits near $1.57 trillion — 57% to 59% of the entire asset class, depending on the tracker. It is the deepest and most widely held pool of capital in the industry.

Almost none of it is doing anything. Spark’s BTCFi research, published 29 May 2026, put Bitcoin’s DeFi footprint at 91,332 BTC — 0.46% of circulating supply, or about 0.8% counting every wrapped variant and all of Babylon’s staking. Threshold’s July 2026 follow-up measured roughly 91,000 BTC. The same research puts Ethereum’s DeFi penetration near 15% of ETH supply.

So the gap is roughly thirty-fold, and it is not a demand problem. Holders want liquidity without selling; the tax event and the lost position are both real costs. The gap exists because of where Bitcoin lives.

Why can’t you do any of this on Bitcoin itself?

Bitcoin’s base chain has no lending markets, no perpetuals, no automated market makers and no stablecoins, and that is a design decision rather than a missing feature. Bitcoin Script can verify a signature, enforce a timelock and check a hash preimage. It cannot run the persistent, composable contract state a money market or an order book needs. Ten-minute blocks make anything price-sensitive slow, and there is no native dollar to price a loan in.

So every use case below has the same first step: value has to move to a chain that can execute it. That step is the part most guides skip, and it is where the real cost and the real risk live. Once value is there, you no longer hold Bitcoin. You hold a token that tracks its price, whose risk is the issuer’s or the bridge’s.

What can you actually do with Bitcoin in DeFi?

1. Borrow stablecoins against it

Borrowing against Bitcoin is the most used thing you can do with it, and the only one here that leaves your position intact. You deposit a Bitcoin-denominated token as collateral, borrow USDC or USDT against it, and repay later. No sale, so in most jurisdictions no disposal at the point of borrowing.

Aave is the biggest venue: over $14.6 billion in total value locked as of mid-2026, more than $3 billion of it in Bitcoin markets. It accepts WBTC and cbBTC, with WBTC carrying a 73% maximum loan-to-value and a 78% liquidation threshold. Morpho is second at over $1.5 billion in BTC vaults.

The honest part: this is a margin loan, and margin loans liquidate. Borrow at 50% LTV against a 78% threshold and your collateral only has to fall about 36% before the protocol sells it for you, at a price you did not pick. Bitcoin has produced that drawdown repeatedly.

2. Stake it

Bitcoin staking pays a yield for locking BTC in a timelock script on the Bitcoin chain itself, without wrapping or bridging it anywhere. The coins stay under your keys; the stake secures other proof-of-stake networks, and those networks pay for it.

Babylon is the category, not just the leader: over $4 billion in TVL and roughly 57,000 BTC as of May 2026, close to 80% of everything counted as Bitcoin DeFi. Lombard, at about $1.5 billion, issues the liquid staking token most people use to keep the position tradeable.

The honest part: yields are low single digits, lockups are real, and the liquid staking wrapper reintroduces exactly the token risk native staking was meant to avoid. Solv Protocol, another large player in the category, was exploited in March 2026.

3. Trade with it

Once Bitcoin is on an EVM chain or Solana you can trade it against anything else on-chain, at any hour, without an account. Uniswap is the largest decentralised exchange by volume and the deepest venue for WBTC and cbBTC pairs against ETH and stablecoins.

The honest part: for the plain trade of Bitcoin into dollars, a centralised exchange is almost always cheaper. On-chain trading earns its keep when the thing you want is not listed anywhere else — a token on a rollup, a new asset, something that never reaches an exchange.

4. Post it as margin for perpetuals

Perpetual futures venues let you take leveraged directional positions, and the largest on-chain one is Hyperliquid, which processed $633 billion in volume in Q1 2026, holds roughly 70% of decentralised perp volume and about 6.2% of the global perps market including centralised exchanges.

The honest part, and it is the whole story: Hyperliquid margins in USDC, not in Bitcoin. Putting BTC to work there means converting it first, which is a disposal, after which you hold dollar collateral and a synthetic position that can be closed against your will. A legitimate trade, but not the trade of holding Bitcoin.

5. Supply it to a liquidity pool

Supplying Bitcoin to an automated market maker earns a share of trading fees on the pair. Uniswap v3 and Curve are the two venues that matter.

The honest part: for most holders, this is the worst option on the list. Bitcoin pools are thin — the WBTC/cbBTC pool on Base showed roughly $270,000 of liquidity against $135,000 of daily volume in 2026. And a volatile pair carries impermanent loss, so a large BTC move can leave you with less than holding would have. Fee income on a thin pair rarely covers it.

6. Convert it and pay someone — Lightning, or stablecoin rails

If the goal is to send value rather than hold a position, Bitcoin has two working answers and neither is a DeFi protocol. Lightning settles small BTC payments in seconds for cents, and is the right tool when both sides want bitcoin. For paying someone who wants dollars, converting to USDC or USDT and sending on a cheap chain is the standard route.

The honest part: spending Bitcoin is selling Bitcoin. A card, a payment processor and a stablecoin conversion are all disposals, taxable in most jurisdictions, and a year of small ones is worse to account for than a single sale.

7. Buy tokenised stocks and real-world assets with it

Tokenised equities are the newest destination, and Bitcoin is a legitimate funding source for them. On Solana, Kamino Lend handles 82.6% of tokenised stock lending — $31 million of the $53 million of tokenised stock collateral on the network as of late July 2026. Robinhood’s own chain is building in the same direction.

The honest part: $53 million across an entire chain is a small market. The rails work, the depth does not exist yet. Early rather than established.

Which of these are actually worth it?

How do you get Bitcoin onto an EVM chain, Solana or a rollup?

Four routes exist, and they differ mainly in who holds your Bitcoin while you are using the token. Ask that first; the fee difference is usually smaller than the custody difference.

A centralised exchange: Deposit BTC, sell or convert, withdraw the destination asset. For common pairs — BTC to USDC, BTC to ETH — this is frequently the cheapest route available and worth checking before anything else. It costs you an account, KYC and the exchange holding your coins in between, and it fails outright for most rollups, which exchanges do not support as withdrawal networks.

Mint directly from the issuer: Coinbase issues cbBTC, BitGo WBTC, Kraken kBTC, Binance BTCB, and Circle launched cirBTC on Ethereum on 8 June 2026. You are trading Bitcoin for a claim on that institution’s reserves, which buys the deepest liquidity and the widest acceptance in lending markets. Threshold’s tBTC is the decentralised alternative: 51-of-100 threshold signers, about $5 billion of cumulative bridge volume, no losses in six years.

Cross-chain swap protocol: Garden Finance, THORChain, and Chainflip all move native BTC to other chains without an exchange account, and they differ more in coverage than in what they enable. THORChain reaches the most standalone L1s; Chainflip runs a short, deliberate asset list across six chains. Garden’s catalogue on 8 September 2026 listed 26 assets across 15 chains, including Lightning, Solana, Starknet, Spark, Ink and Hyperliquid, 13 of those entries a form of Bitcoin across seven tickers. In a nine-swap cost snapshot on 20 August 2026, Garden quoted lowest on all nine and Chainflip highest, the gap widest on $100 swaps.

Bitcoin-native layer 2: Spark and Stacks run BTC as the network’s own asset rather than a company’s token — less counterparty concentration, thinner liquidity, fewer applications waiting. Botanix, often named in this category, announced a full wind-down on 9 June 2026.

What to check before you move anything

Check the token, not the ticker. WBTC on Starknet is a different token from WBTC on Ethereum, and cbBTC is three separate contracts across Ethereum, Base, and Solana.

Have gas on the destination. Arriving with a Bitcoin token and no ETH, SOL or STRK is the most common way a first attempt stalls.

Size to the destination’s liquidity, not to your balance. Caps exist on every route, and inside them the far side’s depth sets your slippage.

Assume the conversion is taxable. In most jurisdictions giving up BTC for a token is a disposal, and coming back is a second one.

FAQ

Can I use Bitcoin in DeFi without wrapping it?
Yes, in one case. Babylon’s staking locks native BTC in a timelock script on the Bitcoin chain, so the coins never leave and are never wrapped. Every other use case here needs a representation of Bitcoin on another chain.

Is wrapped Bitcoin the same as Bitcoin?
No. It is a token on another chain representing BTC held elsewhere, and its risk is the issuer’s rather than Bitcoin’s. cbBTC is a claim on Coinbase, WBTC on BitGo, kBTC on Kraken.

What is the safest way to earn yield on Bitcoin?
Native staking through Babylon has the fewest moving parts, because the BTC stays on Bitcoin under your own keys. Lending on Aave is more liquid and adds smart-contract and wrapped-token risk on top.

How much Bitcoin is actually in DeFi?
About 91,000 BTC, or 0.46% of circulating supply, per Spark’s May 2026 research and Threshold’s July 2026 update — roughly 0.8% counting every wrapped variant and all Babylon staking.

Can I use Bitcoin in DeFi on Solana?
Yes. cbBTC is the main Bitcoin representation on Solana, and Kamino is the largest money market there at around $3.2 billion in TVL, with Jupiter Lend second.

Is a bridge cheaper than an exchange?
Often not, for common pairs. Exchanges usually win on BTC to USDC or BTC to ETH. Bridges win when the destination is a rollup the exchange does not support, which is most of them.

Why did Bitcoin DeFi shrink in 2026?
Layer-two and sidechain TVL fell 74% in Q1 2026, and the broader ecosystem about 10%, from 101,721 BTC to 91,332. Threshold’s read is that capital rotated toward verifiable custody and a dependable route back to native BTC.

Do I have to sell my Bitcoin to trade perps?
Effectively yes. The major perp venues, Hyperliquid included, margin in USDC rather than Bitcoin, so the conversion is unavoidable.

Coinbase CEO Brian Armstrong Says Clarity Act Will Pass — And That Bitcoin Bottom Is In

Coinbase CEO Brian Armstrong has said that bitcoin’s bottom is in and reiterated that the coin will hit $400,000 by 2030. 

Speaking on CNBC Thursday, the head of America’s biggest crypto exchange said that he was confident the long-awaited crypto Clarity Act would pass next week. 

Bitcoin was trading sluggishly throughout June and July but started surging in August, spurred on by positive regulatory news. Over a 30-day period, the largest cryptocurrency is currently up over 20%. 

JUST IN: Coinbase CEO Brian Armstrong tells CNBC the Bitcoin "bottom is in" and BTC hitting $400,000 by 2030 is a "reasonable target" pic.twitter.com/RYfipYCNDk

— Bitcoin Magazine (@BitcoinMagazine) September 10, 2026

“[$400,000] is a reasonable target by 2030, and if you follow crypto, you know it typically goes through these four-year-ish cycles: there’ll be a run-up, some euphoria, there’ll be a down period,” Armstrong said. 

“Most of the down periods last about a year, and we’ve actually just come across the one-year mark for this down period, so I personally believe that the bottom is in.”

Bitcoin was recently trading for close to $77,318 per coin. It hit a new all-time high of $126,080 in October. 

Market observers have been paying attention to the long-awaited Clarity Act this year. The bill drafts a framework to formally divide oversight between regulators, distinguishing which digital assets are securities, commodities or stablecoins. The crypto industry has long called for such rules to be in place. 

Senators will vote on the long-awaited legislation next week after an August delay. 

U.S. President Trump helped spur a surge in the bitcoin price when he hosted crypto executives and traditional finance bigwigs at the White House and urged lawmakers to move forward with the bill. 

Armstrong said on Thursday that he was confident the bill would get through — and help unlock new capital as a result. 

“We saw with the Genius Act that passed last year for stablecoins: in the wake of that legislation passing, we saw well over 150 large companies integrate stablecoins within just a three-month period,” he said. 

“And I think something similar could happen with the Clarity Act passing — it’s a regulatory checkbox, it’d be a big milestone certainly to unlock institutional capital and to bring things like tokenized equities and perks to the United States, which would be very good.”

Coinbase and Better Mortgage Announce General Availability of Bitcoin-Backed Mortgages 

Coinbase and Nasdaq-listed Better Mortgage have announced the availability of Bitcoin-backed mortgages for Americans. 

The crypto exchange and lender said Wednesday that the service was designed in accordance with the Federal National Mortgage Association, or Fannie Mae. 

Coinbase and Better announced the funding of the first Bitcoin-backed mortgage in June. The service now hopes to cater to younger wannabe homeowners who have Bitcoin holdings.

— Bitcoin Magazine (@BitcoinMagazine) August 26, 2026

“In 2025, high interest rates, record home prices, and limited inventory pushed the median age of a first-time homebuyer to 40,” Chief Technology Officer at Better Mortgage, Ziggy Jonsson, said. 

“Coinbase counts millions of monthly users worldwide, and by allowing Coinbase One members to pledge crypto as collateral without selling their holdings, we’re opening a new path toward homeownership for a generation of borrowers whose wealth increasingly lives onchain.”

Ben Shen, head of financial services and loyalty products at Coinbase, added: “By enabling borrowers to pledge their digital assets in the mortgage underwriting process, we are allowing crypto to be more useful and powerful in the real-world — expanding the pathways to homeownership while preserving long-term investment positions.”

The announcement added that Coinbase One members will be eligible for a rebate equal to 1% of the mortgage value, up to a maximum of $10,000.

The debut loan by Coinbase and Better was closed by a married Michigan couple, Joe and Amy, in June. The couple used their Bitcoin holdings as collateral to fund their down payment rather than liquidating their position, the companies said at the time. 

Crypto-backed lender Milo said earlier this year that it had surpassed $100 million in digital asset mortgages, including a record $12 million loan, as more high-net-worth and institutional clients were using Bitcoin as collateral for home financing.

Bitcoin-backed loans are still a niche product but one of the biggest lenders in the space, Ledn, has released research claiming that the space could grow from its current size of $3 billion to $1 trillion in the next 10 years.
