Through its partnership with Stacks, Sui is gearing up to introduce sBTC, a programmable cryptocurrency backed by Bitcoin. This strategic move aims to establish Sui as a key player in Bitcoin's DeFi sector, which currently holds $9.68 billion in locked assets.
On May 1, 2025, a major partnership was announced between SUI, the rapidly expanding Layer 1 blockchain, and Stacks, the leader in Layer 2 solutions for Bitcoin.
This collaboration, revealed through a post on X by Stacks, marks a significant step towards integrating sBTC, an asset pegged 1:1 to Bitcoin, into the SUI ecosystem.
SUI, developed by Mysten Labs, is a renowned Layer 1 blockchain known for its speed, scalability, and native tools like zkLogin, which facilitate Web3 adoption.
According to the official announcement, SUI plans to integrate sBTC in the coming months, an asset designed by Stacks to make Bitcoin programmable and compatible with smart contracts. With a scheduled launch for the summer of 2025, this integration will enable SUI to become a key player in Bitcoin DeFi, a rapidly growing sector.
sBTC, backed by a decentralized network of validators and audited by experts like Asymmetric Research and ImmuneFi, offers a secure and decentralized alternative to unlock Bitcoin liquidity. As highlighted by Adeniyi Abiodun, co-founder of Mysten Labs:
“So far, BTC has been treated as an inert asset. sBTC activates Bitcoin liquidity in a decentralized manner, unlocking Bitcoin DeFi across any ecosystem while benefiting from the security of Stacks’ signers.”
sBTC is a revolutionary asset: each unit is pegged to a Bitcoin (1:1) and can be used in DeFi applications, unlike native Bitcoin which remains limited in terms of programmability.
With a TVL exceeding $286 million, sBTC is becoming a cornerstone of the Bitcoin DeFi ecosystem.
According to DefiLlama, Bitcoin-based protocols have already amassed a Total Value Locked (TVL) of $9.68 billion, with players like Babylon Protocol and Solv Protocol leading the way.
The integration of sBTC on SUI will allow users to interact with decentralized exchanges (DEX) like Cetus or Kriya, which have already processed over $11.1 billion in transactions in the last 30 days on SUI.
Stacks, as a Layer 2 for Bitcoin, positions itself as a central gateway to power the Bitcoin economy. This partnership with SUI is part of a broader strategy: following a successful collaboration with Aptos in September 2024, Stacks continues to expand the adoption of sBTC to other major blockchains. As stated by Muneeb Ali, founder of Stacks:
“sBTC is the safest and most decentralized way to make Bitcoin productive. SUI’s growth in DeFi and its underlying technology make it a natural destination for sBTC.”
SUI, already ranking among the top 10 blockchains with over $2.5 billion in assets and $889 million in stablecoins, is a fertile ground for sBTC. About 10% of SUI’s TVL is already composed of Bitcoin, indicating a keen interest in this asset.
This partnership comes at a favorable time for both networks. On April 25, 2025, BitGo, a leader in institutional custody, integrated sBTC on Stacks, enhancing investor confidence. This announcement had led to a significant increase in the price of STX, Stacks’ native token, a sign of growing enthusiasm.
On the other hand, SUI has proven expertise in liquidity management, notably through initiatives like its hackathon on non-custodial liquid staking in 2023. With sBTC, SUI could attract even more developers and liquidity, potentially driving up the value of its token SUI. Moreover, sBTC yields on SUI were announced at the Sui Basecamp.
The integration of sBTC on SUI could unlock some of the $1 trillion of Bitcoin capital currently unused, according to stacks.co. By making Bitcoin productive without reliance on centralized custodians, sBTC paves the way for new use cases, from lending to decentralized exchanges.
Other blockchains, like Cardano, are also exploring solutions to integrate Bitcoin through technologies like zero-knowledge proofs, but the decentralized approach of Stacks and SUI puts them at the forefront.
Currently, the STX token is trading at $0.84 and is up 2.89%. Some analysts predict highs of $5, $10, or even $20 for the most optimistic in a bullish cycle for altcoins.
In conclusion, the partnership between SUI and Stacks marks a turning point for Bitcoin DeFi. By integrating sBTC, SUI positions itself as a significant player in the ecosystem, while Stacks strengthens its role as a central hub for the Bitcoin economy.
With an imminent launch and a booming Bitcoin DeFi market, all eyes are now on the evolution of STX and SUI tokens. One thing is certain: the future of Bitcoin in DeFi has never seemed more exciting.
