Sui Integrates Stacks’ sBTC—Unlocking $5.8B in Bitcoin DeFi Firepower
Sui just threw gasoline on Bitcoin DeFi’s smoldering potential—adding native support for Stacks’ sBTC bridges the king coin to its high-speed blockchain.
The move taps into BTCfi’s $5.8B TVL behemoth, letting Bitcoin holders finally earn yield without trusting wrapped token middlemen (or Wall Street’s 2% ‘high-yield’ savings accounts).
Smart contracts meet hard money—with fewer hopium-fueled intermediaries taking their cut.

Moreover, the sBTC support will enable developers to access this massive liquidity via a decentralized asset. At the same time, they’ll be able to build “more composable applications with rich asset behavior” through Sui, the announcement says.
Additionally, Sui notes that they’ve already entered the Bitcoin DeFi space with multiple previous partnerships. This includes,,, and.

Sui says that it will continue to “lay the foundation for the most complete Bitcoin DeFi ecosystem in crypto.” Adding sBTC is the latest step, which will enable the coin holders to “repurpose” their BTC and leverage Sui’s expanding DeFi ecosystem.
The team also argues that Sui is an “ideal home” for BTC-backed assets due to its parallelized execution and object-centric design based on theprogramming language.
Meanwhile, the rise in demand for BTCfi has been noticeable. Bitcoin DeFi protocols hit $6.5 billion in total value locked (TVL) by the end of 2024, the announcement notes. This figure currently stands at $5.84 billion, according to.
Notably, Sui says, Bitcoin has an “intentionally conservative architecture” that limits native DeFi, but Layer-2s built for this purpose have emerged. These solutions, including Stacks, enable smart contracts and decentralized applications (dapps) without altering Bitcoin’s CORE protocol.
This helps expand utility. “With Stacks, Bitcoin holders can put their BTC to work through lending, swapping, and liquid staking—all secured by the Bitcoin network,” the announcement says.
At the same time, Sui supports decentralized exchanges (DEXs), lending, and liquid staking within the DeFi space.
As Adeniyi Abiodun, Co-Founder at Mysten Lab, the contributor to Sui, put it:
"Up to now, BTC has been treated as an idle asset"
"sBTC activates Bitcoin liquidity in a decentralized way, unlocking Bitcoin DeFi across any ecosystem while benefiting from Stacks Signers’ security"
Moreover, the Sui team says that more than 10% of Sui’s total TVL is in BTC and Bitcoin-derived assets, just months after the network enabled BTC bridging and staking.
“sBTC is the safest, most decentralized path to making Bitcoin a productive asset,” said Muneeb Ali, Founder of Stacks. “Sui’s DeFi growth and powerful underlying technology make it a natural destination for sBTC.”
