Top Bitcoin DeFi Projects and Tokens to Watch in 2026

The top DeFi projects on the Bitcoin network to watch in 2026 start with Stacks, worth $573.6 million at the late-October close. This list covers six Bitcoin DeFi projects that stake or lend bitcoin or run chains built around it. Bedrock and Babylon come next by value at that close, with Fractal Bitcoin, Merlin Chain and Core behind them.

Bitlight (LIGHT), a Bitcoin smart-contract project outside CoinGecko's two Bitcoin DeFi categories, rose 36.83% in a single day in late October 2026. Of the 17 tokens in those categories that closed late October worth $10 million or more, only 5 rose that day and the median move was -1.35%.

Top Bitcoin DeFi Projects at a Glance

What Is Bitcoin DeFi?

Bitcoin DeFi is lending, staking and trading built on Bitcoin, or on chains and tokens that carry bitcoin to places where it can earn. The projects behind it often call themselves BTCFi projects.

Most of that activity runs on Bitcoin layer 2 projects and sidechains, or on other chains that hold a bitcoin-backed token. Two models split the field. In one, your BTC stays on Bitcoin and secures something else, which is how Babylon's staking works. In the other, BTC moves into a token on another chain and earns there, as with Bedrock's uniBTC on Ethereum.

A BTCFi coin is the token one of these projects issues, such as STX or CORE, and it trades apart from the BTC the project handles. That's why a good month for bitcoin can still be a bad month for the token.

How We Chose the Six

We started with the 43 tokens in CoinGecko's "BTCfi Protocol" and "Bitcoin Sidechains" categories and ordered them by market value at the late-October close. We then dropped projects whose own sites don't put Bitcoin first, along with one that describes itself as built and backed by exchanges. The top seven left at that close run down to Core at $27.37 million, and the cards below follow that order.

Threshold (T), whose tBTC carries Bitcoin onto Ethereum and other chains, also passes this filter and has its own explainer.

Stacks (STX)

Stacks is the Bitcoin layer behind sBTC, and STX closed late October at $0.3055, down 2.26% on the day. CoinGecko valued it at $573.6 million at that close, and CoinMarketCap at $553.4 million.

In late October 2026, Stacks' STX page said its Proof of Transfer system "has run in production since January 2021 and paid BTC to stakers every cycle since (4,224BTC distributed)". The cost is dilution, because "Block rewards add ~2% to STX supply yearly." STX/USDT still trades on Phemex spot, though an early October 2026 notice removed its margin pairs and Phemex delisted the STX perpetual in August 2026.

Bedrock (BR)

Bedrock runs BTC vaults that mint uniBTC, a bitcoin-backed token. BR closed late October at $0.4626, down 7.79%. Ethereum alone held 2,980 uniBTC at that close, a floor because it counts one chain.

This is the BR token, separate from an Ethereum layer 2 upgrade with the same name. Its weak spot is contract code, which failed in September 2024 when attackers exploited the uniBTC vaults. Its Phemex perpetual was delisted under a July 2025 notice, and its spot pair under a July 2026 one.

Babylon (BABY)

Babylon lets holders stake native BTC on Bitcoin itself as security for other chains, and BABY closed late October at $0.01338, up 1.96%. Its staking data showed about 40,920 BTC in active stakes across roughly 10,460 delegations in late October 2026, a live count that changes as stakers come and go.

Supply is the risk here. Only 4.92 billion of its 11.04 billion BABY circulated at the late-October close, so more than half sat outside circulation. Phemex removed the BABY perpetual under a June 2026 notice and the spot pair under a July 2026 one.

Fractal Bitcoin (FB)

Fractal Bitcoin runs a chain built from Bitcoin's own code, and FB closed late October at $0.3803, down 0.71%. Bitcoin aims for a block every 10 minutes, while Fractal's documentation says it "confirms a block every 30 seconds".

The chart shows the risk. FB's intraday all-time high on CoinGecko was $38.80 in September 2024, and the late-October close left it about 99.0% below that peak. Phemex's FB perpetual was delisted under an August 2025 notice, and FB has no order-book spot pair on Phemex.

Merlin Chain (MERL)

Merlin Chain is a Bitcoin layer 2, and MERL closed late October at $0.02699, down 1.16%. Merlin's documentationsays "The Merlin Chain, launched in January 2024, is a new project that originated from Bitmap Technology".

A layer 2 like Merlin runs on top of a base chain, and our explainer on the blockchain layers shows how they stack. Supply is the overhang here, with 1.43 billion of 2.1 billion MERL circulating at the late-October close. MERL's Phemex spot pair was delisted under a June 2026 notice and its perpetual under July 2026 notices.

Core (CORE)

Core is a Bitcoin-powered chain for BTC staking, and CORE closed late October at $0.01823, up 1.26%. It's a separate thing from Bitcoin Core, the node software of Bitcoin itself.

Core's own site gives CORE a "fixed supply of 2.1 billion tokens", with block rewards paid out "over an 81-year period". The weak point is price, since CoinGecko's lowest print for CORE to late October was $0.01637 in mid-October 2026 and the close stood only 11.3% above it.

CORE's perpetual and spot pair on Phemex are delisted, the perpetual under a January 2026 notice and the spot pair under a July 2026 one.

Did Bitcoin DeFi Tokens Move Together in Late October?

Most of them fell, while Bitlight broke away. LIGHT went from $0.2277 to $0.3116 on CoinGecko over one day in late October 2026, a 36.83% gain, and CoinMarketCap's daily closes put it at 37.42%.

The two categories went the other way. Of the 17 tokens in CoinGecko's two Bitcoin DeFi categories valued at $10 million or more at the late-October close, 12 closed lower that day. The middle move was a 1.35% fall, while Bitcoin's own perpetual on Phemex slipped 0.36%. Among the six cards above, Babylon and Core rose and the other four fell.

Bitlight's late-October jump was its own, because most large Bitcoin DeFi tokens closed lower that day. It doesn't belong to either category, so you can't read its spike as a sector signal for the six above.

Method: each move runs from one CoinGecko daily close to the next, and the median is the ninth of the 17 moves in order. CoinMarketCap's daily closes agree in sign for Bitlight and Stacks, and Phemex's STX/USDT spot pair fell 2.30% on the same day.

Is Bitcoin Staking Safe?

Bitcoin staking is only as safe as the code and custody behind it, and the yield it pays is thin.

Bedrock shows the code risk. Rekt's account of the exploit says attackers took about $2 million on 25 September 2024, after a vault upgrade let users mint one uniBTC for each ETH they deposited. Rekt also reports that the upgrade skipped an audit.

Babylon shows the pay problem. In late October 2026 its staking data put the yield on staked BTC at about 0.04% a year, with the top rate under 1%, and the reward comes in BABY. Your BTC stays on Bitcoin under your own keys, though Babylon's documentation says security violations trigger slashing of a portion of the stake.

Stacks pays the other way round, in BTC to people who lock STX, and sBTC moves bitcoin onto Stacks for use in its apps. In every case the safety question comes down to who can move the coins and what pays the yield.

Risks of Bitcoin DeFi Tokens

Four risks run through the whole list, and each comes with a dated example.

• Exploits hit the contracts that mint bitcoin-backed tokens, and Bedrock's 2024 flaw reached eight chains before the team paused its vaults.

• Unlocks and new supply matter because much of each token has yet to circulate. Under 30% of BR's 1 billion tokens circulated at the late-October close, and about 599 million CORE sat outside circulation.

• Tiny yields paid in the project's token shrink when that token falls, and BABY closed late October about 92% below its April 2025 intraday high on CoinGecko.

• Delisted markets limit where you can trade. Every one of the six has a delisted Phemex perpetual, and only Stacks keeps an order-book spot pair there. Futures use leverage, and a leveraged position is closed automatically if losses reach its margin.

Frequently Asked Questions

Is Bitcoin DeFi or CeFi?

It's DeFi when code holds the coins and CeFi when a company does. Babylon's staking keeps BTC in the staker's own wallet on Bitcoin, while a bitcoin-backed token on another chain depends on the contract or custodian holding the BTC behind it.

How do you earn yield on Bitcoin?

The main routes are staking BTC through a protocol such as Babylon, which paid about 0.04% a year in BABY in late October 2026, or depositing it with a vault that mints a token such as uniBTC. Each route adds contract risk to bitcoin's own price risk.

What are the best Bitcoin DeFi projects?

Stacks led the Bitcoin-first projects by CoinGecko market value at the late-October close, at $573.6 million, with Bedrock and Babylon next. Value measures size, so read each project's named risk before you rank them.

Which Bitcoin DeFi coins trade on Phemex?

STX/USDT is the one order-book spot pair on Phemex among these six, though its margin pairs and the STX perpetual are delisted. The other five have delisted Phemex perpetuals, and four of them also have delisted spot pairs.

Bottom Line

A Bitcoin DeFi token is a bet on one project's code and supply, with bitcoin's price as one input among several. The late-October numbers make that plain. Bitcoin barely moved while most big tokens in the group slipped, and Bitlight's jump came from outside it.

So treat one token's spike as that token's news until its peers confirm it, and weigh any yield against the token it pays in.
