Sui To Support sBTC & Stacks, Unlocking Powerful Institutional BTCfi Use Cases

This integration will enable holders to deploy their BTC into decentralized finance by tapping into Sui’s scalable, composable infrastructure without relying on centralized custodians. Sui Foundation will also operate a validator on the Stacks network.

By bringing sBTC to Sui, Bitcoin’s $1.6 trillion in liquidity will gain access to new onchain opportunities that preserve the asset’s native security while unlocking DeFi use cases like lending, borrowing, and trading.

“For too long, BTC has been treated as a passive asset,” said Adeniyi Abiodun, Co-Founder and Chief Product Officer at Mysten Lab, the original contributor to Sui. “sBTC on Sui means holders can earn yield, participate in DeFi, and stay true to Bitcoin’s trustless ethos—all on Sui, a blockchain built for performance and scale.”

Scaling BTCfi on the Only Blockchain Built for Mass Adoption

The demand for Bitcoin-based DeFi is growing rapidly. By the end of 2024, Bitcoin DeFi protocols reached $6.5 billion in total value locked (TVL). 

Bitcoin’s intentionally conservative architecture has historically limited native DeFi, but layer-2 solutions like Stacks are expanding its utility by enabling smart contracts and decentralized applications without altering Bitcoin’s core protocol. With Stacks, Bitcoin holders can put their BTC to work through lending, swapping, and liquid staking—all secured by the Bitcoin network.

Meanwhile, next-gen layer-1 blockchains such as Sui offer high throughput and scalability for DeFi and other use cases. Sui’s high-performance blockchain supports a rapidly growing DeFi ecosystem, including decentralized exchanges (DEXs), lending, and liquid staking, powered by its object-based architecture and parallel execution for fast, low-cost transactions. 

With this utility now on Sui, holders can repurpose their BTC and tap into Sui’s flourishing DeFi ecosystem, known for its fast, low-cost, and high-performance infrastructure. Sui’s parallelized execution and object-centric design based on the Move programming language make it the ideal home for BTC-backed assets.

Already among the top 10 chains by TVL and in the top 6 in monthly DEX volume, Sui’s DeFi ecosystem is booming with opportunities for Bitcoin DeFi. In fact, over 10% of Sui’s total TVL is in BTC and Bitcoin-derived assets, mere months after BTC bridging and staking became available on the network.

“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. We’re excited to expand BTCfi to a top ecosystem that stands out for its utility and rate of adoption.”

Expanding Bitcoin’s Utility

The upcoming sBTC integration builds on Sui’s momentum in Bitcoin DeFi. Earlier this year, Sui expanded BTCfi partnerships with Babylon, Lombard Finance, and Cubist, and welcomed SatLayer, a leading Bitcoin restaking platform.

With sBTC, developers gain access to Bitcoin liquidity through a decentralized asset that aligns with Bitcoin’s native principles. And Sui’s high-speed, asset-first design enables developers to build more composable applications with rich asset behavior that is all backed by secure infrastructure.

About Stacks
Stacks, the leading Bitcoin L2, enables smart contracts and decentralized applications to use Bitcoin as a secure base layer. The Nakamoto release, activated on October 29, 2024, brought faster speeds and transactions that are as irreversible as Bitcoin’s once confirmed. This set the stage for sBTC, a programmable Bitcoin asset, which launched on December 17, 2024. Stacks is the current leading Bitcoin L2 by developer traction and market cap and is helping unlock Bitcoin and its $1T in passive capital as a fully programmable, productive asset. The Stacks (STX) token, used as gas on the L2, was the first to undergo an SEC-qualified sale in the United States. The project explicitly decentralized with the mainnet launch in 2021. In the Stacks ecosystem, there are currently 30+ contributing entities including a non-profit Stacks Foundation, a developer tooling company Hiro, Xverse, Trust Machines, Mechanism, Bitcoin L2 Labs, ALEX, Bitcoin Frontier Fund, and more.
